Production Process of Oil Casing Pipe

Production process of oil casing pipe

Cold drawing: Tube billet – inspection – shearing – heating – hot perforation – heading – capillary tube storage – pickling, phosphating, saponification – cold drawing – heat treatment – physical and chemical experiments – straightening – cutting head and tail – surface and size inspection – eddy current testing – ultrasonic testing -Turning wire and tube end processing Hot rolled: Tube billet- inspection – cutting – ring furnace heating – perforation – tube rolling – micro tension reduction – straightening – cutting head and tail – inspection – non-destructive testing – hydraulic test – Turning wire and tube end processing

Quality Inspection:

Conventional non-destructive testing + hydrostatic test (magnetic particle testing MPI, eddy current testing ET, ultrasonic testing UT, radiographic testing RT.)
