Chemical Industry 304 304L Seamless Stainless Steel Pipe 316L 310S
Stainless steel seamless tube is a hollow round steel, widely used
in petroleum, chemical, medical, food, light industry, machinery
and instruments, such as industrial transportation pipelines and
mechanical structure parts, etc.. In addition, the bending and
torsion strength of the same time, the weight is lighter, so it is
also widely used in the manufacture of machinery parts and
engineering structures. Also used for production of various
conventional weapons, artillery barrel, etc..

A, according to GB14975-94 "stainless steel seamless steel pipe",
the length of the steel pipe is usually length (not constant) hot
rolled 1.5 ~ 10m, hot extrusion steel pipe is equal to and greater
than 1m. Cold drawing (rolling) steel pipe wall thickness of 0.5 ~
1.0mm, 1 ~ 7m; the wall thickness is greater than 1.0mm, 1.5 ~ 8m.
B, hot rolling (hot extrusion) steel pipe diameter of 54 ~ 480mm a
total of 45 species; wall thickness of 4.5 ~ 45mm a total of 36
species. Cold drawing (rolling) steel pipe diameter of 6 ~ 200mm is
65; the wall thickness is 0.5 to 21mm 39.
C, both inside and outside the pipe surface shall not have cracks,
folding, cracking, crack, rolling reduction, separation and
scarring and defects, these defects should be completely removed
(except for machining tube), after the removal of the outer wall
thickness and shall not exceed the negative deviation. Any minor
surface defects not exceeding the allowable negative deviation may
not be removed.
D, direct channel allows depth. Hot rolled, hot extruded steel
pipe, the diameter is less than or equal to 140mm less than 5% of
the nominal wall thickness, the maximum depth of not more than
0.5mm; cold drawing (rolling) steel is not greater than 4% of the
nominal wall thickness, the maximum depth of not more than 0.3mm.
E, both ends of the tube should be cut into right angles, and
remove the burr. Manufacturing process of stainless steel seamless
Characteristics of stainless steel seamless tube:
First, the product of the wall is thicker, it is more economical
and practical, the wall thickness of the thinner, processing costs
will be substantially increased it;
secondly, the product process to determine its performance
limitations, generally low precision seamless steel pipe: uneven
thickness, tube inner surface brightness low and high cost of fixed
length, and the inner surface pitting and black spots difficult to
remove; the detection and plastic
third, must be processed offline. So it is in high pressure, high
strength, mechanical structure of the material reflects its
Used in industries as chemical engineering, petroleum, medicine,
food, energy, nuclear power, aerospace,
environmental protection, boiler, gas, war industry, machinery,
ship building and so on.
Our factory is near to raw material market and high-speed way, the
producing cost is low.
Our factory have long history for producing stainless steel
seamless pipe,both producing and testing
machine is advanced and perfect.
Our factory was certificated by BV/ISO/LR/RINA/CCS/GL/ABS/DNV,
which can improve the quality.
We participated in many famous projects with our pipes.
