Product Description

Product Description

It has high strength and wear resistance, high hardenability, medium cold deformation plasticity, and acceptable welding
performance. During heat treatment, the toughness of steel decreases less, and it can still maintain high toughness when water cooling, but it has overheat sensitivity, white spot sensitivity and temper brittleness tendency. It is mostly used after quenching and tempering, and can also be used under normalizing or hot rolling supply conditions. It is used for geological drilling, oil drilling, oil drill collars, automobile half-shafts, ships, etc.

Import and export steel pipes

Generally, the import volume of seamless pipe is large. The main importing countries are Germany and Japan. European countries such as Romania, Russia, Switzerland, France, Spain, the Czech Republic, Yugoslavia, Hungary and other countries have imported. There are also a small amount of imports from Argentina, Mexico and other countries in South America.
According to the different requirements of the consumer in China, there are more than 100 types of imported seamless pipes, including 15922mm, 1595mm and 15918mm. 114.38mm,114.310mm,114.313mm. The length is generally 5-8m or 4-7m. Mainly hot-rolled carbon structure and ST65. The minimum diameter of the inlet specification is 305 mm, and the maximum diameter is 47813 mm.
A small number of seamless pipes with small diameter and thin wall have been imported from France and Spain, such as 183mm, 223mm, 26.93mm, etc. Implement the general rules of Mannesmann Steel Pipe Plant in Germany.
Seamless pipes imported from Hungary and Japan often refer to DIN2448 and DIN1629.

product application

Seamless pipes are widely used. Seamless pipes for general purposes are rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for conveying fluid.
Supply is divided into three types according to different purposes: a. Supply according to chemical composition and mechanical properties; B. Supply according to mechanical properties; C. Supply according to hydraulic test. The steel pipes supplied according to category a and b shall also be subjected to hydraulic test if they are used to bear liquid pressure.
There are many kinds of seamless pipes for special purposes, such as boiler seamless pipes, geological seamless pipes and petroleum seamless pipes.
