Lipped seal

roundwith framepolyurethane

Performance and Purpose: 1.It is made up of sealing ring、fan-shaped supporting blocks and fan-shaped angles. It is mainly used in the pressure test of steel pipe by hydro-static testing machine. 2.As it is designed to test steel pipe from its inner diameter, when testing, the sealing ring will expand to enclose the pipe inner diameter to achieve the purpose of sealing. 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.Its test head is smaller than type D or C and production cost is lower as well. It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe. Working conditions: Working pressure: ≤ 60 M Pa Working temperature: -20℃～+80℃ Working medium: water, emulsion, hydraulic oil Material: Polyurethane
