D-type ultra-high pressure large gap sealing element
1. Performance and Use
The D-type ultra-high pressure large gap sealing element is a sealing element composed of a sealing ring and a fan-shaped supporting block, which is mainly used for the pressure test of a steel pipe by a hydraulic testing machine. In the non-working state, there is a certain gap between the sealing element and the sealed surface. When in operation, the sealing element is pressurized by the outer periphery to closely seal with the surface to be sealed, and a hydraulic test is performed. This product is suitable for hydraulic testing of steel pipes such as casing, tubing, and natural gas transportation by hydraulic testing machines. It can also be used for leak detection of steel pipes, pipe joints, welded joints, and ultra-high pressure valve sealing. The C-type ultra-high pressure and ultra-large gap sealing element is a sealing element composed of a sealing ring, a fan-shaped supporting block and a supporting angle.
It is mainly used for the pressure test of steel pipes by hydraulic testing machine. The C-type sealing element has a larger sealing gap than the D-type (see the previous sample of the company for details), and the steel pipe specifications of the same type of seal ring can be applied to a wider range. This product is suitable for hydraulic testing of steel pipes such as casing, tubing, and natural gas transportation by hydraulic testing machines. It can also be used for leak detection of steel pipes, pipe joints, welded joints, and ultra-high pressure valve sealing.
