The pressure of the radiator

Time:2017-12-01 16:00:02   Source:NanHaiWeiYu
We have some general understanding of the installation process of radiators.So tell you about the installation process often appear several "pressure".Test pressure is required inspection radiator air tightness and strength, is 1.2-1.5 times of the working pressure, many manufacturers to test the tightness of the radiator radiator pressure value is 1.8 MPa in the production process, to achieve the requirements of pressure test pressure stable after a minute, the welding deformation, no leakage is qualified.

Centralized heating pressure is generally between 0.4 - 0.6MPa, household heating is generally within 0.2MPa, after installation, air tightness test should be carried out. Under test pressure, the pressure stopping time is 10 minutes,and the pressure drop is not more than 0.05mpa;
The indoor heating system stops for 5 minutes and the pressure drop is not greater than 0.02 mpa. The main points of the inspection are the various
interfaces of the pipes, the radiator, the joints of the pipes and the radiator, and the close degree of various valves and accessories to be qualified without leakage.
As can be seen from the above:
Radiator test pressure is greater than the pressure of work and the work pressure is greater than the system pressure, milan spring radiator in the process of production strictly in accordance with material selection, production process, the pressure resistance of radiator such as security, to use for the user in the process of avoid and reduce the chance of leaks, burst to provide comprehensive protection.
