Flat seal

circularpolyurethanepipe

I．Performance and Purpose: It makes use of the end-face of steel pipe as sealing face to test defect and bearing strength of steel pipe. It is mainly used in the hydraulic testing of large diameter seamless pipe and a variety of welded 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 the pressure on the sealing end-face. II．Material: Polyurethane III．Working conditions: According with several standards about hydraulic testing requirements：such as API 5CT/ISO11960:2011, GB/T9711.1-2011, GB/T9711.2-2011，etc. for Petroleum and natural gas industries—Steel pipes for casing or tubing; GB8163 - 2008 for seamless steel tubes; GB/T3092-2008 for welded steel pipes. ≤30 MPa Working temperature: 0℃～+80℃ Working medium: water, emulsion, hydraulic oil IV．Design standards:Refer to GB/T3672.1-2002 tolerance. V．Sample for ordering sign: Marked the type, size and order No. of the sealing components, Order No. only is also permitted. TypeOrder No. Example:D1092Xd888X50P060
