Titanium alloy seamless pipe is a long pipe made of titanium alloy material with a hollow section and no seams around it. Initially it was mainly used to make aircraft engine compressor components and structural parts for rockets, missiles and high-speed aircraft.

This article mainly introduces the concept of quenching, six major problems and measures in the quenching process of carbon steel seamless pipes.

The expanded connection is made of malleable cast iron or ductile iron as the main material, and consists of a lined pipe body (bushing), nuts or bolts, threaded rings or expanded pressure flanges, and sealing rubber rings. It adopts fastening nuts or pressure flanges. In this way, the pipe compresses the sealing ring, so that the inner surface of the pipe and the sealing ring on the lining pipe body are connected to the metal pipe fittings to form a diagonal sealing connection.

This article introduces the four major factors that affect the service life of stainless steel seamless steel pipes, and how to select high-quality stainless steel seamless pipes.

Solution treatment refers to a heat treatment process in which the alloy is heated to a high temperature and maintained at a constant temperature in the single-phase region, so that the excess phase is fully dissolved into the solid solution and then rapidly cooled to obtain a supersaturated solid solution.

Three defects will occur during the welding process of austenitic stainless steel seamless pipes, and different measures should be taken according to the actual situation.
