Basic knowledge of precision seamless steel pipe
Views: 181 Update Date: Aug 18 , 2017
Precision seamless steel pipe is a kind of high precision steel pipe manufactured after cold drawing or hot rolling treatment. It is mainly used in hydraulic system piping, automobile manufacturing piping, military engineering, railway locomotives, aerospace, ships, injection molding machines, die-casting machines, machine tools, diesel engines, petrochemicals, power plants, boiler equipment and other industrie because of its high precision, high finish, no cracks and it can withstand high pressure without leakage.
Precision seamless steel pipe production process:
Tubing - Inspection - Peeling - Inspection - Heating - Perforation - Pickling - Grinding - Lubrication Drying - Weld head - Cold drawing - Solution treatment - Pickling - Pickling Passivation - inspection - cold rolling - oil removal - cutting head - air drying - internal polishing - external polishing - inspection - logo - finished packaging
Types: DIN series high precision seamless pipe, seamless pipe for hydraulic system, precision seamless steel pipe for automotive manufacturing.
Standard: DIN 2391, DIN2445, EN10305, DIN1629, DIN1630, ASTM A179
