Pipe making & welding
Illustrative only; publish verified equipment lists separately.
Manufacturing & quality assurance
This overview explains how we think about traceability and inspection - it is not a substitute for a facility audit or third-party surveillance report.
Workflow (generic)
- Incoming steel inspection and release
- Forming / welding hold points per WPS
- Surface preparation and coating application under qualified procedures
- Holiday detection, thickness checks, and peel/adhesion tests as specified
- Final documentation bundle for release
ISO 9001 / ISO 14001 / ISO 45001 families are referenced on Baike as part of the management system posture - display official certificates only after client approval.
Program gates (illustrative)
Horizontal timeline for RFQ-to-release storytelling—dates are placeholders, not delivery promises.
RFQ
Line list, standards, and inspection regime captured.
Tech review
Coating build, hold points, and submittals agreed.
Melt / plate
MTC alignment to grade and heat strategy.
Coating
Surface prep, application, cure per procedure.
Inspection
Holiday, thickness, adhesion per ITP.
Release
Documentation bundle + packing list.
Video placeholder: no hosted walkthrough yet—add a short loop only after you have rights-cleared factory footage and a compressed poster frame.
Finished goods protection
Bevel protection, dunnage, and sea-fastening follow the contract packing list.
Inspection & release
Holiday detection, thickness, and adhesion tests per ITP and invoked standards.
