Description

Bellows shock resistance test device

Technical Field

The utility model relates to the field of corrugated pipe tests, in particular to a corrugated pipe impact resistance test device.

Background

The metal corrugated pipe is a thin-wall element with corrugated surface, is generally made of austenitic stainless steel and high nickel alloy, and is an important elastic element in petrochemical industry and engineering. Fatigue failure of metal bellows can present a hazard to the system. Therefore, the service life of the corrugated pipe is ensured to have important significance. Under fatigue, which is the alternating loading of a material or component below its static strength, certain localized or extensive areas first enter a yield state, where high plastic deformation occurs. For each corrugated pipe product, an impact resistance test should be performed when leaving the factory to measure the impact resistance.
