ORDER

MELTING

01

Based on melting, electric arc furnaces or induction furnaces stabilize the composition of molten steel, while refining furnaces remove impurities and optimize alloys.

PIERCING & FORMING

02

Punching machine produces hollow blanks, extruded/
rolled into pipes, with uniform wall thickness and no pores.

COLD DRAWING & WELDING

03

Cold drawn molds accurately stretch tube blanks to ensure precise size.

NDT

06

Eddy current+ultrasonic+water pressure testing, comprehensive defect inspection to verify pressure bearing capacity.

PICKLING & POLISHING

05

Acid washing to remove oxide skin, polishing to improve smoothness and corrosion resistance.

HEAT TREATMENT

04

Dissolve the fire control temperature, optimize the microstructure, and ensure consistency in data monitoring.

DIMENSIONAL & VISUAL INSPECTION

07

Verify size parameters against standards, ensure surface is flawless (no scratches/cracks).

PACKING & SHIPMENT

08

Package per customer specs (plastic wrap/rust film/
caps), ensure safe transport; packing list/labels guarantee accuracy.
