Model Number: Type U sealing components Key Specifications/Special Features: I. Performance and purpose: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-faceII. Material:polyurethaneIII. Working conditions:According with several standards about hydraulic testing requirements such as API 5CT/ISO 11960:2011, GB/T9711.1-2011, GB/T9711.2-2011 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 MPaWorking temperature: 0 to +80℃Working medium: water, emulsion, hydraulic oilIV. Design standards: refer to GB/T3672.1-2002 tolerance
