What is a thermal test schedule? Promstroy company video
General information
Based on the Rules technical operation thermal power plants (approved by order of the Ministry of Energy of the Russian Federation dated March 24, 2003 N 115), when operating heating network systems, heating network enterprises must ensure the reliability of heat supply to consumers, the supply of coolants (water and steam) with flow rates and parameters in accordance with the temperature control schedule and inlet pressure drop.
During operation, all operating heating network must be tested for strength and density to identify defects no later than two weeks after the end of the heating season.
Hydraulic testing of pipelines of water heating networks in order to check strength and density should be carried out by test pressure with the results entered into the report.
Test pressure is the excess pressure at which hydraulic testing of thermal power plants and networks should be carried out for strength and density.
The minimum test pressure during hydraulic testing is 1.25 working pressure, but not less than 0.2 MPa (2 kgf/cm2).
The maximum value of the test pressure is established by strength calculations according to the normative and technical documentation agreed with the State Mining and Technical Supervision Authority of Russia. The test pressure value is selected by the manufacturer (design organization) within the range between the minimum and maximum values.
Hydraulic tests are carried out by the person responsible for the safe operation of heating networks together with personnel authorized to operate heating networks.
Hydraulic tests
When conducting hydraulic tests To determine the strength and density of heating networks, heating network equipment (stuffing box, bellows compensators, etc.), as well as sections of pipelines and connected heat-consuming power plants not involved in the tests, should be disconnected by plugs.
Strength and density tests are carried out in the following order:
disconnect the tested section of the pipeline from existing networks;
in the most high point Set the test pressure of the section of the pipeline under test (after filling it with water and bleeding air) (control using a pressure gauge);
the pressure in the pipeline should be increased gradually;
the rate of pressure rise must be indicated in the regulatory and technical documentation (NTD) for the pipeline.
Tests for strength and density are carried out in compliance with the following basic requirements: pressure measurement during testing should be carried out using two certified spring pressure gauges (one control) of class not lower than 1.5 with a body diameter of at least 160 mm. The pressure gauge must be selected from the condition that the measured pressure value is within 2/3 of the instrument scale; test pressure must be provided at the top point (mark) of the pipelines; the water temperature must be no lower than 5 °C and no higher than 40 °C; when filling with water, air must be completely removed from the pipelines; the test pressure must be maintained for at least 10 minutes and then reduced to working pressure; at operating pressure, a thorough inspection of pipelines is carried out along their entire length.
The test results are considered satisfactory if during the test there was no drop in pressure and no signs of rupture, leakage or fogging were found in the welds, as well as leaks in the base metal, in valve bodies and seals, in flange connections and other pipeline elements. In addition, there should be no signs of movement or deformation of pipelines and fixed supports.
A report of the established form is drawn up on the results of testing pipelines for strength and density.
The results of hydraulic testing of a pipeline for strength and tightness are considered satisfactory if during the testing there was no pressure drop, no signs of rupture, leakage or fogging were found in welds, as well as leaks in the base metal, flange connections, fittings, compensators and other pipeline elements , there are no signs of shift or deformation of the pipeline and fixed supports.
Many residents of Ulyanovsk have no idea or suspicion about how they pass and why they are needed temperature tests heating networks for maximum temperature coolant. This year, in particular, it is planned to raise it to 140 degrees in the districts of Far Zasviyazhye: Sviyaga-8, Sviyaga-9, Sviyaga-10, Ryabikova-2, Ryabikova-3, Ryabikova-4 ", "UZTS-3", "UZTS-4", pos. “White Key”, “Profsoyuznaya”, “Experimental Field” on April 28 and 29.
Now we will answer several basic questions and explain the situation in more detail:
1. Why is this necessary?
The purpose of the tests is to identify all defects in pipelines, compensators, supports, and thermal deformations that occur when the coolant temperature increases to the maximum value, as well as when it subsequently decreases to the original level. The tests will allow the next heating season to frosty days if necessary, raise and maintain the temperature of the coolant in heating networks at the exit from the thermal power plant in accordance with temperature chart 150/70 C.
Thus, the quality of heat supply to consumers receiving heat from Volzhskaya TGC OJSC will be ensured. In addition, the holding of such events every five years is regulated by the Technical Operation Rules, so that power engineers can understand how ready the system is for the new period.
2. Why was this date chosen for testing?
This is the most optimal date, due to the fact that the end of the heating season is planned for holidays and carrying out tests after, in fact, will be considered inappropriate, in order to avoid this and possible consequences on holidays, according to the Decree of the City Administration, temperature tests will be carried out on April 28-29.
3. Will such a high temperature get into both the tap and the batteries?
For safety reasons during the testing period hot water supply will be turned off all consumers connected to centralized system heat supply. There will also be heating turned off schools, children's preschool institutions, healthcare institutions. During the tests, water will circulate in the heating systems of residential buildings for 5 - 6 hours elevated temperature.
Residents whose apartments have polypropylene pipes installed should not worry, because even when high-temperature coolant is supplied to internal system the house must be provided with network water from the supply and return pipelines, and the coolant will enter the heating system with a temperature of no higher than 95 degrees, and this corresponds to the standards.
It is also noted that sometimes during testing, management organizations arbitrarily shut down systems central heating V residential buildings, in addition to the necessary safety shutdown of hot water supply. This is contrary to the test program and may negatively affect their conduct, causing an increase in pressure in the pipelines and causing damage.
IMPORTANT: Managers of management companies, homeowners' associations, housing cooperatives need to complete the entire range of technical and organizational measures to prepare for temperature tests.
4.Who will pay for the heating that is provided during the tests?
In this case, because heating season has not yet been completed, all consumers in the indicated quarters will be recalculated for heating fees (specifically for two days, when temperature tests will be carried out). An increase in coolant temperature will not lead to an increase in the board.
5. What precautions must be taken?
First of all, you need to be careful when handling heating appliances. To avoid emergency situations during testing, hot water taps should be kept closed. If in the heating unit of a residential building the shut-off valves that turn off the hot water are faulty, and the hot water actually continues to flow, we recommend that you exercise caution when using water, establish increased control and exclude small children from access to mixing devices.
There are 4 types of testing of heating networks:
- For strength and tightness (crimping). Performed at the manufacturing stage before applying insulation. When used annually.
- At design temperature. Carried out: to check the operation of compensators and fix their working position, to determine the integrity of fixed supports (1 time every 2 years). Tests are carried out during the manufacture of networks before applying insulation.
- Hydraulic. They are carried out with the aim of determining: the actual water consumption of consumers, the actual hydraulic characteristics of the pipeline and identifying areas with increased hydraulic resistance (once every 3-4 years).
- Thermal tests . To determine actual heat losses (once every 3-4 years). Tests are carried out according to the following dependence:
Q = cG(t 1 - t 2) £ Q norms = q l *l,
where q l is the heat loss of 1 m of pipeline, determined according to SNiP “Thermal insulation of pipelines and equipment”.
Heat losses are determined by the temperature at the end of the section.
Strength and tightness tests.
There are 2 types of tests:
- Hydraulic.
- Pneumatic. Checked at t n<0 и невозможности подогрева воды и при её отсутствии.
Hydraulic tests.
Instruments: 2 pressure gauges (working and control) class higher than 1.5%, pressure gauge diameter not lower than 160 mm, scale 4/3 of the test pressure.
Order of conduct:
- Disconnect the test area with plugs. Replace the stuffing box expansion joints with plugs or inserts. Open all bypass lines and valves unless they can be replaced with plugs.
- The test pressure is set = 1.25 P slave, but not more than the working pressure of the pipeline P y. Exposure 10 minutes.
- The pressure is reduced to operating pressure, and inspection is carried out at this pressure. Leaks are monitored by: pressure drop on the pressure gauge, obvious leaks, characteristic noise, fogging of the pipe. At the same time, the position of the pipelines on the supports is monitored.
Pneumatic tests It is prohibited to carry out for: Overhead pipelines; When combined with other communications.
During testing, it is prohibited to test cast iron fittings. It is allowed to test fittings made of ductile cast iron at low pressures.
Instruments: 2 pressure gauges, pressure source - compressor.
- Filling at a rate of 0.3 MPa/hour.
- Visual inspection at pressure P ≤ 0.3P tested. , but not more than 0.3 MPa. R use = 1.25 R work.
- The pressure rises to P tested, but not more than 0.3 MPa. Exposure 30 min.
- Reducing pressure to P slave, inspection. Leaks are determined by the following signs: a decrease in pressure on pressure gauges, noise, bubbling of a soap solution.
Safety precautions:
- during the inspection it is prohibited to go down into the trench;
- Do not get exposed to air flow.
Design Temperature Tests
Heating networks with d ≥100mm are tested. In this case, the design temperature in the supply pipeline and in the return pipe should not exceed 100 0 C. The design temperature is maintained for 30 minutes, while the increase and decrease in temperature should not be more than 30 0 C / hour. This type of test is carried out after the networks have been pressure tested and breaks have been eliminated.
Tests to determine thermal and hydraulic losses
This test is carried out on a circulation circuit consisting of supply and return lines and a jumper between them, all branches of the branch are disconnected. In this case, the decrease in temperature along the ring is caused only by heat losses of the pipelines. The test time is 2t to + (10-12 hours), t to is the travel time of the temperature wave along the ring. Temperature wave - an increase in temperature by 10-20 0 C above the test temperature along the entire length of the temperature ring, is established by observers and the temperature change is recorded.
The test for hydraulic losses is carried out in two modes: at maximum flow and 80% of the maximum. For each mode, at least 15 readings must be taken with an interval of 5 minutes.
There is a launcher and a user testing of heating networks. It is divided into pressure testing, hydro- and heat testing, as well as testing for the highest temperature of the coolant. Pressure testing is necessary to establish the density and mechanical strength of the pipe route, fittings, and equipment.
Start-up crimping of ductless lines, also in non-through passages, is carried out in 2 stages - initially and finally. Its duration is determined by the period required to survey the lines.

Hydrotests are needed to establish the actual hydroindications of a new line and equip points or transform these values when used. During this testing, p is simultaneously transformed, waste along with t of the coolant in certain segments of the heating network. Based on the measurement values p in the supply and return pipelines, the actual piezometric mode is built, and based on the liquid waste in places, the calculation mode p is established. The differences between the specific and calculated piezometric modes are formed by comparison.
Thermal tests are needed to determine the actual heat losses in the lines and compare them with calculated and standardized readings. The need for this testing is dictated by the usual damage to thermal insulation, its replacement in separate places, and also by transformations of buildings. During testing, the waste and t of the coolant at the base and end of the investigated part of the delivery and return pipelines are replaced.
Testing at the highest temperature of the coolant is carried out to audit the practicality of buildings, the performance of correctors, the displacement of risers, to identify real stresses and distortions of the more loaded parts of the heating line.
Heating mains are also tested for strength and impermeability. They are performed both on separate segments and on the general line in general. When performing these tests, client devices must be turned off, and they are also tested separately.
- Testing can be carried out on water and steam heating lines for heat consumption.
- Testing of water heating lines for hydraulic flows.
In addition, it is possible to do:
- Analysis of the probability of “stray” currents (electrical transformation to identify the corrosive activity of soils and the dangerous impact of “stray” currents on the pipelines of heating networks underground);
- Analysis of the highest temperature of the coolant;
Calculate the cost of testing the heating network for you
Testing to identify heat losses in heating lines should be carried out once every five-year period on routes characteristic of this heating network according to the class of insulating structures being erected, shelf life and use situations, to prepare energy readings and standardize user heat losses, in addition to analyzing the technical position of heating lines. The results of these tests are used to standardize the operating costs of heat energy, also taken into account:
- When determining an economically justified payment for performing a service when supplying heat;
- When preparing regulatory energy indicators for heating lines;
- When determining in heat supply contracts the values of heat energy properties at the lines of responsibility with heat energy subscribers;
- For commercial energy calculations;
- When testing the effectiveness of energy release procedures, and also during methodological energy surveys;
- During testing of the technical position of thermal insulation structures of heating pipelines;
Heating networks can also be tested using calculated t.
Cost of testing heating networks
Heating networks with a diameter of less than 10 cm are analyzed. Here, the supply pipe route must have a calculated t, and the “return” must have no more than 100 g. Celsius. The temperature itself is maintained after half an hour, but the increase and decrease in temperature must be more than thirty degrees. Celsius per hour. This testing is carried out after crimping the lines and removing breakthroughs.
And finally, a test to establish heat and hydraulic flow rates of heating networks.
This testing takes place on a rotating circuit, which consists of a delivery and return network and a jumper between them; all clients of the branches are disconnected. Here, the decrease in t along the flow along the ring occurs only through heat waste from the pipe lines. The testing period is a certain period of travel t of the flow along the ring.
T flow - increase it by 10-25 g. Celsius greater than the test value over the entire distance of a given ring is determined by contemplatives and the transformation t is fixed.
Testing for hydraulic flow takes place on 2 levels: as a result of the largest flow rate and 80 points from the largest. For each of the routines, at least fifteen indicators should be taken with an interval of five minutes.
