AISI 4130 4135 4140 High quality alloy steel cold rolled seamless
steel tube
Product Description
Including seamless pipes for general structures, mechanical
structures, seamless pipes for low and medium pressure boilers,
seamless pipes for high pressure boilers, seamless pipes for
conveying fluids, cold drawn or cold rolled precision seamless
pipes, steel pipes for geological drilling, petroleum Testing of
cold-rolled seamless steel pipes for drilling steel pipes, seamless
pipes for precise inner diameter of hydraulic cylinders, seamless
pipes for chemical fertilizers, marine pipes, oil cracking pipes,
and various alloy pipes.
Cold rolled seamless tube is a seamless steel tube for high
dimensional accuracy and good surface finish.Cold rolled seamless
pipe in addition to include the general steel,low and medium
pressure boiler tube,high-pressure boiler tubes,alloy steel
pipe,stainless steel pipe and oil cracking tube,also includes
carbon thin wall steel pipe,alloy thin wall steel tube,thin-walled
stainless steel pipe and special-shaped steel tube.The diameter of
cold rolled seamless steel pipe is 6mm,wall thickness is
0.25mm,while the diameter of thin-walled tube can be 5mm,wall
thickness can less than 0.25mm.The dimensional accuracy of cold
rolling is higher than that of hot rolling.
Advantage of cold drawn seamless steel pipe:
Forming fast,high yield,and no damage to the coating,it can be made
into a variety of cross sectional form to meet the needs of the use
of conditions;Cold rolling can cause great plastic deformation,so
as to improve the yield of the steel.
The technological process of cold-drawn(rolled) seamless steel
tubes:
Tube blanks→Heating→Punching→Heading→Annealing→Pickling→Oil coating
(copper plating)→Many times cold drawing (cold rolling)→ Blank
tube→Heat treatment→Straightening→Hydrostatic test (flaw
detection)→Marking→Warehouse.
