IType C of large gap ultrahigh-pressure sealing components
I．Performance and Purpose:
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 hydrostatic testing machine. Type C has more 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 gage. It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe. It has also been used in leak test of the steel pipe，welded joints and sealing for the ultrahigh pressure valve.
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.
Working pressure: ≤ 120 MPa
Working temperature: -20℃～+80℃
Working medium: water, emulsion, hydraulic oil
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.
