![Type D of large gap ultrahigh pressure sealing componets - 1](https://img.directindustry.com/pdf/repository_di/201042/type-d-large-gap-ultrahigh-pressure-sealing-componets-913990_1m.jpg)
Performance and Purpose The sealing component is made up of o polyurethane sealing ring ond fan-shaped supportors. It is mainly used in the pressure test of steel pipe by hydrostatic testing machine, in the non-working stole between the sealing ring ond surface ot steel ppe exists gap. when hydroulic liQud Is opptied to the external of the seeing ring, the ring is pressed to enclose the surface ot steel pipe firmly, and then the pressure testing can be performed, u is applicable to the pressure testing ot casing, tubing, natural gas poe ond other sfeel pipe. It has also been used in leak inspection of the steel pipe, connection, welded joints and sealing for the high pressure valve. Working concfl lions According with API 5CT-20I8- ISOI1960-2014. GB/T97I1-2017 etc. Such as petroleum and natural gas industries-Steel pipes tor use as casing or tubing tor wens: GB/T8I63-2018 seamless steel tubes: GB/T309I-2015 welded steel pipes, and other standcrd hydraulic testing conditions. Working pressure: < 120 MPa Working temperature: -20 to ‘SO'C Workmg medium: water, emulsion, hydraulic Of Material: Polyurethane Design standards: Refer to GB/T3672.1-2002 tolerance. Sample tor ordering sign: Marked the type, size one order No. of the sealing components. Order No. only is exso permitted, Type Order No. Example: D 168.3-40 D242
