Iran’s biggest seamless steel pipe plant opens
Iranain Minister of Industry, Mine, and Trade Abbas Aliabadi inaugurated the country’s biggest seamless steel pipe factory in Abhar, Zanjan Province, in northwestern Iran.
The factory is equipped with the most modern manufacturing technology for seamless steel pipe production, which has also created 1,000 jobs directly, as well as 3,000 jobs indirectly, IRNA reported.
Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes.
According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes.
According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-shaped pipes include square, oval, triangular, hexagonal, melon seed, star, and finned pipes.
The maximum diameter is 900mm and the minimum diameter is 4mm. According to different purposes, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes.
Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and
aviation.
