Introduction to stainless steel
tube:
**4 **6 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 ~ **0T 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.
