Performance and Purpose

This end-face sealing ring is mainly used in the hydraulic testing of large diameter seamless pipes and a variety of welded steel pipes. When testing, pay attention to maintain the balance of oil and water pressure, and keep a uniform speed and strength during pressing. When releasing water pressure, it is important to have a good follow-up of oil pressure to prevent the sealing ring being damaged by a sudden change of the pressure on the sealing end-face caused by the insertion of the steel pipe.
