Product Manufacturing Process
Tube blank
Inspection (spectral detection, surface inspection, and dimensional inspection)
Sawing
Perforation
Thermal inspection (alloy steel requires heat treatment)
Pickling
Grinding inspection
Lubrication
Cold drawing
Lubrication
Cold-drawing (the addition of cycled processes such as heat treatment, pickling and cold drawing should be subject to the specific specifications)
Normalization
Performance test (mechanical property, impact property, hardness, flattening, flaring, and flanging)
Straightening
Tube cutting
Non-destructive testing (eddy current, ultrasonic, and magnetic flux leakage)
Hydrostatic test
Product inspection
Packaging
Warehousing
Product Manufacturing Equipment
Shearing machine, sawing machine, walking beam furnace, perforator, high-precision cold-drawing machine, heat-treated furnace, and straightening machine
Product Testing Equipment
Outside micrometer, tube micrometer, dial bore gage, vernier caliper, chemical composition detector, spectral detector, tensile testing machine, Rockwell hardness tester, impact testing machine, eddy current flaw detector, ultrasonic flaw detector, and hydrostatic testing machine
Product Applications
Equipment in petrochemical industry and heat exchangers
Package of carbon steel seamless pipe
Plastic caps plugged at the two sides of pipe ends
Should be avoided by the steel strapping and transport damage
Bundled sians should be uniform and consistent
The same bundle(batch) of steel pipe should be came from the same furnace
The steel pipe has the same furnace number,the same steel gradethe same specification
