China stainless steel pipe manufacturers 304, 316L, 321, 310S
stainless steel tube
HAOSTEEL is one of the most professional manufacturer and supplier
of stainless steel Tube.Stainless steel tube can be divided into
seamless tube and welded tube according to production mode.
Seamless tube can be divided into hot rolled tube, cold rolled
tube, cold drawn pipe and extruded tube.The welded pipe is divided
into straight welded pipe and spiral welded tube.
Description:
According to the metallographic structure of stainless steel, the
seamless tubes of semi-ferritic semi-martensitic stainless steel,
martensitic stainless steel, austenitic stainless steel and
austenitic ferritic stainless steel are divided.
Specification and appearance quality:
A. According to gb14975-2002 "seamless steel pipe of stainless
steel", the normal length of steel pipe (indefinite ruler) is
1.5-10m. The hot-rolled steel pipe is equal to and greater than
1m.Cold drawn (rolled) steel pipe wall thickness of 0.5~1.0mm,
1.0~7m;Wall thickness greater than 1.0mm, 1.5-8m.
B. 45 types of hot-rolled (hot-extruded) steel tubes with a
diameter of 54~480mm;Wall thickness: 4.5-45mm, total 36 kinds.There
are 65 kinds of cold drawn (rolled) steel tubes with diameter of
6~200mm.There are 39 kinds of wall thickness ranging from 0.5 to
21mm.
C. There shall be no cracks, folds, cracks, cracks, rolled folds,
dissociation and scarring defects on the inner and outer surface of
the steel pipe. These defects shall be completely cleared (except
for the pipe used for machining).Other minor surface defects not
exceeding the allowable negative deviation may not be removed.
D. the straight path allows depth.Hot-rolled and hot-extruded steel
tubes with diameters of less than and equal to 140mm shall not be
greater than 5% of the nominal wall thickness and the maximum depth
shall not be greater than 0.5mm.Cold drawn (rolled) steel tube
shall not be greater than 4% of nominal wall thickness and the
maximum depth shall not be greater than 0.3mm.
E. Both ends of the steel tube shall be cut at right angles, and
the burr shall be removed.
