The frequency of pressure tests on resin pipes needs to be determined comprehensively based on the application scenario, industry standards, and product type. Generally, it is recommended to conduct a periodic inspection at least once a year to ensure the safety and reliability of the piping system. However, in specific operating conditions or critical applications, the inspection cycle may be shorter.
Routine Inspection Cycle
Annual Routine Inspection: For resin pipes in most industrial, building, and municipal systems, a pressure test is recommended annually unless there are special changes in operating conditions. This helps to detect problems such as aging, corrosion, or structural damage in a timely manner, preventing the risk of sudden leaks or pipe bursts.
Type Testing Triggering Conditions: In addition to periodic inspections, a type test for pressure resistance should be performed immediately when one of the following situations occurs:
New product launch or material formula change
Production process adjustment or equipment replacement
Resumption of production after shutdown
Production malfunctions or abnormalities during use
Customer quality concerns or project acceptance requirements
