Large gap ultra-high-pressure sealing components (Type C)


Price :

Performance and Purpose:
Comprised of a sealing ring, fan-shaped supporting blocks and fan-shaped angles, this product is mainly used by a hydro-static testing machine for the the pressure testing of steel pipes by hydro-static test. Type C has a larger seal gap than Type D (refer to company’s former catalogue). The sealing components with same dimensions are applicable to a wider range of steel pipe sizes. It is applicable to the pressure testing of casings, tubings, natural gas pipes and other steel pipes. It has also been used in leak testing of the steel pipes, welded joints and sealing for the ultra-high pressure valves.

Description

Ultra-High-Pressure Sealing Components

Advantages :
1. Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing.
2. 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.

Working conditions:
Compliant for use with several standards about hydraulic testing requirements including API 5CT/ISO11960:2011 Petroleum and natural gas industries—Steel pipes for casing or tubing, GB/T9711.1-2011, GB/T9711.2-2011; GB8163-2008 for seamless steel tubes; GB/T3092-2008 for welded steel pipes.

Working pressure: ≤ 120 MPa
Working temperature: -20℃~+80℃
Working medium: water, emulsion, hydraulic oil

Material: Polyurethane
