operational principle

The working principle of the corrugated pipe tensile tester is to apply longitudinal tension to the corrugated pipe through a stretching device, and at the same time, the measurement system records the force value and displacement data during the stretching process. The control system precisely controls the stretching process based on the set parameters, and processes and analyzes the test results through data analysis software.

GB/T 15820: This is a national standard of the People's Republic of China, which specifies the test method for longitudinal tensile resistance of polyethylene (PE) pressure pipes and fittings after connection. This standard equivalently adopts the international standard ISO 3501:1976, which is applicable to the connection of polyethylene (PE) pressure pipes with a diameter not exceeding 63mm and fittings of different materials and structural forms, but not suitable for fusion welding connection.

International standards:

1. ISO 3501: This is a standard developed by the International Organization for Standardization (ISO), which specifies the tensile strength test for the assembly joints between polyethylene (PE) pressure pipes and fittings. Similar to GB/T 15820, it mainly tests the tensile strength of pipes and fittings after connection.
