hydraulic prop tube process flow

The 27siMn hydraulic prop tube is mainly used in coal mine hydraulic supports, columns and cylinders, as well as other hydraulic columns and cylinders. The 27siMn hydraulic support tube is based on the high quality carbon structural steel, with the appropriate addition of one or several alloy elements to improve the toughness, strength and hardenability of the steel. After the steel is made, it usually needs to undergo surface quenching, chemical heat treatment, tempering and other heat treatment. Compared with high quality carbon structural steel, it has good comprehensive mechanical properties and is rolled into flat, square and round steel, which is used as an important part of machinery or machine.

27siMn hydraulic pillar tube corrosion resistance itself is not stainless steel, of course corrosion resistance is not, but wear resistance, cutting performance is much better than stainless steel.

27siMn hydraulic strut tube work flow:

Industrial pipe process:

Tube billet heating - inspection - skin - - - perforation, pickling, fix the mushroom - lubrication dry - welding head - cold drawn - solid solution treatment, pickling, pickling passivation - inspection

Sanitary mirror tube process:

Tube billet heating - inspection - skin - - - perforation, pickling, grinding, dry lubrication, welding head, cold drawing, solid solution treatment, pickling, pickling passivation - inspection - cold rolled - oil - cutting head - dry - polishing, polishing, inspection, identification, finished product packaging
