Acceptance certificate for internal heating systems. Heating system acceptance certificate

Certificate of pressure testing of the heating system - important document, which is the result of hydraulic testing work and a guarantee normal functioning one of the main life support systems for Russians during the cold season.

FILES

In what cases is it compiled?

The act is required when:

• Commissioning of new equipment. The certificate will confirm that each element is in its place, the installation was carried out responsibly, and the system is working.
• Offensive heating season. After a summer break in work, the pipes could fail. After checking their capacity, a report is drawn up.
• Already carried out repair work Oh.
• The emergence of docked emergency situations on the pipeline. Experts thus identify the volume necessary work, weaknesses of the existing heating network.

For the uninterrupted operation of the heating system, preventative control checks and reliable information about the quality functioning of the system upon startup are necessary.

Who produces

Individuals never carry out pressure testing of the heating system on their own, as this is associated with a health risk. Crimping requires specific skills and knowledge.

Therefore, to carry out heating checks, they turn to specialized organizations. This could be a heating company. Also has the right to carry out such work service company, if it has a specialist with suitable education and skills on its staff.

The essence and types of crimping

Nowadays heating is most often carried out by a “water circuit” system. At the same time, heated water circulates through the works, imparting its thermal energy to the premises. Leaks are not allowed, the pipeline for normal operation must be completely sealed. Pressure testing specifically creates a larger volume in the pipe than normal.

When this is done using air, it is called pneumatic pressing.

When using water, then hydropressing. The latter method is considered safer and therefore more popular. For this reason, an example of hydropressing is provided as a form.

When testing, it is recommended not to exceed the pressure inside the pipe more than 15 MPa. If we're talking about about raising pressure with water, there are limitations. The maximum possible pressure should not exceed the normal operating pressure by more than 30%.

IN multi-storey buildings they resort to pneumatic pressure testing if the pipes are very old and there is a risk of flooding. But then there is a level of risk and all residents must be notified of the tests being carried out.

The work process is simple, but multi-stage. The algorithm looks like this:

• Preparations are underway necessary materials and equipment.
• Draining the liquid that was previously in the heating system.
• Uploading a new one.
• Create the highest possible test pressure.
• Taking control measurements after 10 minutes.
• Washing, adjustment heating system before normal indicators pressure inside.
• Documentation of work performed, generation of reports and acts.

But this is how the list of procedures looks only if there are no “thin spots” in the heating system and, accordingly, the tightness in it is not broken. If the pressure drops quickly and does not hold, then the system needs repair work. In such a situation, the specialist performs the necessary actions (replacing the pipe, sealing connections, cleaning, etc.), and then begins crimping from the very beginning. Only a heating system that has passed the test is allowed into the heating season.

Important nuance! Pressure testing should be carried out after cleaning and flushing the pipes. Otherwise, salt and other deposits inside them can mask possible external damage and breakthroughs.

If there are deposits of about 1 cm on the inner surface, then this reduces the overall heat transfer and efficiency by 15 percent or more of the overall indicators. To document the cleaning, a special report is also drawn up.

Is paper mandatory?

The form and sample provided are an example, a recommended form for drawing up an act, but not a mandatory document for everyone. Perhaps, in some cases, other options for recording the work being carried out to check utility systems will be more convenient. By the way, the hot water supply system is also checked through hydraulic testing.

Components of the heating system pressure test report

At the top left is information about the organization that carried out the inspection. Ideally, there should be a signature for approval by the chief power engineer of the heating supply organization.

The top right should contain subscriber information. That is, about who is the client and consumer of heating services. This could be a partnership of residents of a particular house, any organization that occupies the building, the owner of a private house, etc.

It is important to provide names and other information accurately and in detail. In this case, an address is required.

The main part of the act states:

• City.
• The date of signing the act (and the pressure test itself).
• Heat supply organization: its form of ownership, name, full name of the representative.
• Which of the subscriber's representatives accepted the heating system after the test: full name, position.
• To what indicators the pressure in the system was raised is indicated in kgf/cm2.
• To what indicators did it drop after 10 minutes following the shutdown (the units of measurement here are also kgf/cm2, it is also permissible to measure it in mPa if accurate data on this matter is available).
• Whether the system passed or failed the test (the person completing the form needs to highlight the correct option).

The final part consists of the signatures and seals (if any) of the representatives:

• Subscriber.
• Heat supply organization.
• Service organization.

In general, the act of pressure testing a heating system is convenient. primary document, for filling which the heat supply organization is responsible.
