Production process of JCOE large diameter straight seam welded pipe:
Steel Coil→ Re-test→ Flat Open and Transverse Shear→ Shear (Longitudinal Shear)→ Edge Planning and Milling→
Butt Welding of Plate→ Forming (Bending/Reeling)→ End Squaring&Tack Welding→ Welding Seam Cleaning→
Automatic Welding→ Radiographic Test→ Solution Treatment→ Rounding→ Straightening→ End Facing Treatment→
Hydrostatic Test→ Pickling Passivation→ Rinse and Dry→ Radiographic Test→ Finished Product Testing→ Marking→
Packing→ Finished Product Warehousing→ Shipping
Application:
Electric Power, Oil Refining, Nuclear Power, Drinking Water, Offshore Engineering&Shipbuilding, Natural Gas, Paper Making, Construction

Company Introduction
QUALITY CONTROL
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking
100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects
