Large diameter butt welded pipe fitting

Large diameter butt welded pipe fittings

　　The end seals of large-diameter welded steel pipe hydraulic testing machines usually have two types of end seals and radial seals. The earliest end face seals are sealed by the preparation of paralysis, the life is short, and the labor intensity of the workers is large. The radial sealing method uses a radial sealing rubber ring mounted on the test head to extend into the inner part of the steel pipe, and the internal pressure is used to achieve the contact sealing between the rubber ring and the inner wall of the steel pipe. The sealing ring has a long service life and is relatively convenient to install, and the installation is relatively convenient. Labor intensity, but there are shortcomings in the tube end test pressure zone.

　　The new face seal of large diameter welded steel pipe adopts high-strength polyurethane sealing material. Due to the application of electro-hydraulic proportional control technology, it can maintain proper sealing force and protect the sealing ring. The large-diameter welded steel pipehas a longer working life, is more convenient to install, and greatly reduces the dead zone of the test pressure. Nowadays, this sealing method has been widely used in large domestic welded pipe enterprises.
