ASTM Seamless Steel Pipe Pipeline & Water Galvanized Tube

Seamless steel pipe is made of whole round steel perforated, the surface of the
steel pipe without weld, called seamless steel pipe. According to the
production method, the seamless steel pipe can be divided into hot rolled
seamless steel pipe, cold rolled seamless steel pipe, cold drawn seamless steel
pipe, extrusion seamless steel pipe, pipe jacking and so on. According to the
section shape, the seamless steel pipe is divided into round and irregular two
kinds, irregular pipe has square, oval, triangle, hexagonal, melon seed shape,
star shape, with a variety of complex shapes. The maximum diameter is 900mm and
the minimum diameter is 4mm. According to different uses, there are thick wall
seamless steel pipe and thin wall seamless steel pipe. Seamless steel pipe is
mainly used for petroleum geological drilling pipe, petrochemical cracking
pipe, boiler pipe, bearing pipe and automobile, tractor, aviation high-
precision structural steel pipe.



Seamless carbon steel pipe are divided into hot-rolled and cold-rolled (drawn)
steel pipes.
Hot rolled carbon steel pipe is divided into general steel pipe, low and medium
pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe,
stainless steel pipe, petroleum cracking pipe, geological steel pipe and other
steel pipes.



The seamless steel pipe is made of perforated whole round steel, and the steel
pipe without weld seam on the surface is called seamless steel pipe. 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 pipe jacking. According to the
cross-sectional shape, the seamless steel pipe is divided into two types: round
and special-shaped. The maximum diameter is 900mm and the minimum diameter is
4mm. According to different uses, 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
industries, boiler pipes, bearing pipes and high-precision structural steel
pipes for automobiles, tractors and aviation.
