Tube (Barrel)
a. Preparation (seamless steel tube) - inspection (material, etc.) - quenched and tempered (outsourcing: parts) - machining (outside, shelves, boring seam allowance, flange seam allowance, etc.) - tempering hardness testing-welding (welding pipe joint, flange and other accessories)-boring or honing (rough boring, boring, rolling) - machining(hole slot or the internal and external screw thread) -fitter (drilling) - inspection - anti-rust treatment, storage

b. Preparation (forging) - inspection (material, inspection, etc.), welding (blank butt welding) - welding flaw detection, rough machining- tempering (outsourcing: parts), machining(outside, shelves, boring seam allowance, flange seam allowance, etc.) - tempering hardness testing -welding (welding pipe joint, flange and other accessories)- boring or honing (rough boring, boring, rolling) - machining(hole slot or the internal and external screw thread) and fitter (drilling) - inspection - anti-rust treatment, storage

Piston Rod
