Description

Performance and Purpose 1.The sealing component is made up of a polyurethane sealing ring and fan-shaped supporters. It is mainly used in the pressure test of steel pipe by hydro-static testing machine. 2.In the non-working state between the sealing ring and surface of steel pipe exists gap. When hydraulic liquid is applied to the external of the sealing ring, the ring is pressed to enclose the surface of steel pipe firmly, and then the pressure testing can be performed. 3.Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing. 4.The fan-shaped supporters , in the premise of increasing the strength of the sealing ring, can shrink and expand in radial direction with the sealing ring. 5.It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe. It has also been used in leak inspection of the steel pipe, connection, welded joints and sealing for the high pressure valve. Working conditions Working pressure: ≤ 120 MPa Working temperature: -20 to +80℃ Working medium: water, emulsion, hydraulic oil Material: Polyurethane
