Type P of plain washer end-face sealing Performance and Purpose if makes use of fhe end-lace of steel pipe as sealing face fo test defect and bearing strength ot steel poe. t is mainly used in the hydraulic testing of large diameter seomiess pipe and a variety of weeded steel pipes. When testing, pay attention to the balance of oil and water pressure, and keep a uniform speed and strength during pressing, when release water pressure. it is important to prevent from the sealing ring being inserted to damage by a sudden change of fhe pressure on the sealing end-face.
