AISI 4130 4135 4140 Alloy Steel Pipe ASTM Cold Rolled Seamless
|
AISI 4130 4135 4140 High quality alloy steel cold rolled seamless steel tube Product Description Cold rolled (drawn)seamless steel pipe: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.
