Pressure test with gas
Pressure testing and gas leak detection
Gas pressure testing and gas leak detection are two important processes in industries and other technical contexts to ensure that pipelines, vessels and other pressurised systems are safe and leak-proof. Gas testing is a method for testing the compressive strength of pipelines and vessels. The process involves injecting gas, usually air or nitrogen, into the system to increase the pressure to a level that exceeds the expected working pressure. This is done to identify any weak points or leaks in the system.
During the pressurisation test, the pressure is carefully monitored and if any indication of excessive load or leakage is detected, action can be taken before the system is commissioned. After a successful pressure test and verification of system integrity, the system can be commissioned with confidence.
At Power Heat, we have a long and documented experience from test pressure with gas and pressure testing with gas and liquid. Test pressure with gas and leak detection is part of the control elements that are carried out during non-destructive testing of e.g.
- pipework
- tanks
- vessel
- composite systems.
Gas pressure testing is done to ensure that pipelines and pressure vessels meet the calculated strength requirements. Testing by gas pressurisation is a hazardous operation because it is not possible to be certain that the device will hold. Because of these risks, there are regulations for testing with positive or negative pressure (AFS 2006:8).
The test equipment, together with risk assessment and the competence of the test personnel, is an important and central part of the regulation. According to the regulation, all organisations that use gas pressurisation as a test method must be accredited by Swedac. The regulation applies to the safety of both their own staff and other people. The Swedish Work Environment Authority is the regulatory authority.
Power Heat is an authorised inspection body
Pressure testing and pressure testing with gas can be used when special requirements exist, such as purity requirements or if it is difficult to drain liquid from the system. Power Heat is an approved inspection body accredited by SWEDAC according to SS-EN ISO/IEC 17020:2012. The accreditation means that we can test systems with up to 150 bar.
Pressure test with gas
Gas pressure testing is an important method to ensure that different types of containers and pipelines are tight and safe for use. The process involves
- gradually increase the pressure in the unit
- monitor any leaks
- ensure that no problems arise.
It is a method used to test the integrity and durability of different types of containers or pipelines at a pressure higher than their normal working load. The purpose of gas pressure testing is to detect any leaks or defects that may occur during use.
Leak detection with gas
Gas leak detection is a method of detecting and locating leaks in pressurised systems. If there are any leaks, the gas will flow out through the weak points. Using a gas detector or leak spray soap bubbles, leaks can be detected. Gas leak detection is a fast and effective method to find even small leaks, which may be difficult to detect by other means.
