Type CD of large gap ultrahigh-pressure sealing components Performance and Purpose The sealing component is made up of a polyurethone sealing ting and tan-shaped supports, it is mainly used in the pressure test of steel pipe Dy hydrostatic testing machine, in the non-working stole between the sealing ring and surtace ot steel ppe exists gop. When hydroulic iiqo>d 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, it is applicable to the pressure testing ot casing, tubing, naturoi gas ppe ond other steel ppe. it has also been used in leak inspection of the steel pipe, connection, welded joints and sealing for the high pressure valve. Working conditions According with API 50-2018. ISOI1960-20U. GB/T97I1-2017 etc. Such as petroleum and natural gas industries-Steel pipes for use as casing or tubing for welts: GB/T8163-2018 sea mess steel tubes: GB/T3091-2015 welded steel pipes, ond other standc'd hydraulic testing cond>tons Working pressure: < 2C0 MPa Working temperature: -20 to ‘SO'C Working medium: wa'er. emulsion, hydroulic o> Material: Polyurethane Design standards: Refer to GB/T3672.1-20D2 tolerance. Sample tor ordering sign: Marked the type, size and order no. of the sealing components. Order No. only is a>'SO permitted. Type Order No. Example: CD 193.7-46 C616
