Seamless steel tube heat treatment is pided into three categories: (1) Final heat treatment to meet the performance requirements of seamless steel products; (2) heat treatment in the heat treatment st...

The crucible defects in the hot-rolled seamless steel pipe are present on the inner surface of the steel pipe, similar to the size of the soybean granules. Most of the crucibles have foreign objects t...

High-precision seamless steel tubes generally improve the properties of the materials by adding alloys to the metal. After cold drawing, the seamless steel tubes need to be subjected to stress relief ...

1: Thick-walled seamless steel pipe castability (castability): refers to the ability of metal materials to obtain qualified castings by casting. Casting properties mainly include fluidity, shortening ...

The seamless steel pipe ferrule is a pipe that will be cut off according to the pipe diameter. Generally, the pipe diameter is 15~32 mm, the 40~50 mm set is three times, and the 70 mm or more set is 3...

A steel pipe with no joints on the outer surface made of a single piece of metal is called a seamless steel pipe. According to the production method, the seamless pipe is pided into a hot rolled pipe,...

The connection method of ssaw steel pipe is generally welded, because the welded pipe is relatively low in cost. Some projects will also use other connection methods due to factors such as constructio...

The thermal expansion seamless steel pipe adopts the expansion technology of the original pipe. The expansion is a pressure processing process that uses hydraulic or mechanical means to force the stee...

When the seamless steel tube is tempered at 650 °C, its impact toughness value is the lowest, that is, the temper brittle zone, so it is not suitable to temper in this temperature range. It should be ...

The surface heat treatment technology of the 45th thick-walled seamless steel pipe is constantly being innovated, and the current technology has been developed more and more sophisticated. Let's take ...
