Introduction to stainless steel tube:
304 316 Pickling Polished Seamless Industrial Precision Inox Tube,Exhaust,
Water, Gas Stainless Steel Round Pipe

Stainless steel pipe is a hollow long cylindrical steel, his scope of
application as a fluid pipeline, mainly widely used in petroleum, chemical,
medical, food, light industry, mechanical instrumentation and other
industrial pipeline and mechanical structural components. Stainless steel
pipes are made of acid and heat resistant billets, heated, perforated,
sized, hot rolled and cut.


Manufacturing method:

According to different production methods, it can be divided into hot rolled
tube, cold rolled tube, cold drawn tube, extrusion tube and so on.
1.1. Hot rolled stainless steel seamless tubes are generally produced on
automatic tube rolling sets. The solid tube blank is checked and cleared of
surface defects, cut into the required length, centering on the perforated
end face of the tube blank, and then sent to the heating furnace for
heating, and perforated on the punch machine. In the perforation at the same
time continuous rotation and forward, under the action of the roll and the
top, the tube blank gradually formed a cavity, called the wool tube. Then it
is sent to the automatic pipe mill to continue rolling. Finally, the wall
thickness of the whole machine is adjusted, and the sizing machine is
adjusted to meet the specification requirements. It is an advanced method to
produce hot rolled seamless steel tube with continuous rolling tube set.
1.2 If you want to obtain seamless tubes with smaller size and better
quality, you must use cold rolling, cold drawing or a combination of both
methods. Cold rolling is usually carried out on a two-high mill. The steel
pipe is rolled in an annular pass consisting of a circular groove with a
variable section and a stationary conical top. Cold drawing is usually
carried out in 0.5 ~ 100T single chain or double chain cold drawing machine.
1.3. Extrusion method: The heated tube blank is placed in a closed extrusion
cylinder, and the perforated rod moves together with the extrusion rod to
extrude the extruded parts from the smaller die hole. This method can
produce smaller diameter steel pipe.
This kind of steel pipe can be divided into stainless steel seamless steel
pipe and stainless steel welded steel pipe (seam pipe) two categories,
according to the different manufacturing process can be
For: hot rolling, extrusion, cold drawing and cold rolling these basic
types, according to the shape of the section and can be divided into round
pipe and special-shaped pipe, widely used is round steel pipe, but there are
some square, rectangular, semicircular, hexagonal, equilateral triangle,
octagonal special-shaped stainless steel pipe.
For the steel pipe under fluid pressure to carry out hydraulic test to test
its pressure capacity and quality, under the specified pressure does not
leak, wet or expansion for qualified, some steel pipe according to the
standard or the requirements of the side test, flaring test, flattening
test.
Seamless stainless steel tube, also known as seamless stainless steel tube,
is made of steel ingot or solid tube blank by perforation of wool tube, and
then made by hot rolling, cold rolling or cold dialing. The specifications
of seamless steel pipe are expressed by the number of millimeters of outer
diameter * wall thickness.
