Stainless Steel Seamless Pipe

The biggest advantage of seamless pipes is that they are durable. Therefore, this type of piping is an indispensable element in the construction of facilities, i.e. for the conduction of gases and liquids, heat exchangers, coils, recuperators, condensers, evaporators, heaters, and as building Modules, for example, drilling, aircraft, motorcycle or bicycle elements. The highest pressure-resistant feature is the seamless stainless steel tube, made from steel rods with holes drilled along the length of the tube, which is how the tubing that produces the barrel is made.
Stainless steel seamless pipe (ss pipe) production process:
Simplify the main production process: round steel → re-inspection → peeling → blanking → centering → heating → perforation → pickling → flat head → inspection grinding → cold rolling (cold drawing) → degreasing → heat treatment → straightening → pipe cutting (sleeve ) ruler) → Pickling/passivation → Finished product inspection (eddy current, ultrasonic, water pressure) → Packaging and storage.
The stainless steel seamless pipe processed according to the above cold drawing and cold rolling can only be regarded as a semi-finished product, and the precision level is very low, which often fails to meet the requirements of users, such as uneven thickness and unevenness of the pipe wall, if there are scratches, internal and external surface pull marks And defects such as spots or pits must be ground. The specific operation procedure is: first inspect the cold-drawn and cold-rolled stainless steel seamless pipe, and then repair and grind the defective parts according to the inspection situation. Grinding form, for small-diameter thin-walled seamless pipes, mechanical overall grinding is usually used. For thick-walled seamless pipes with medium and large diameters, if there is an overall defect problem, mechanical grinding is used; if there is a local defect problem, manual grinding is used (this is more common), and the manual tools are portable electric sanders and inverted sander.
