Manufacturing Process Flow
The production of welded coiled tubing begins with steel strip. Incoming materials undergo material and surface inspections, followed by strip butt welding, cleaning, tube forming, and laser welding. Subsequent steps include sizing, cold drawing, in-line bright annealing, in-line eddy current testing, and hydrostatic or air tightness testing. The process concludes with precision coiling, marking, final inspection, packaging, and shipment. MTSCO’s welded coiled tubing is produced according to this comprehensive process, with critical control points managed through process cards.

Material Properties of 2507
2507 is a duplex stainless steel that combines high strength with excellent corrosion resistance, making it particularly suitable for applications requiring superior resistance to chloride corrosion and high structural strength. It is commonly used in marine environments, chloride-containing media, and systems demanding both pressure-bearing capacity and corrosion resistance. For control line projects requiring a balance between strength and corrosion resistance, 2507 is a common choice.
Quality Control System
· Secondary Inspection of Raw Materials: Raw materials are sourced from suppliers such as POSCO, JISCO, Outokumpu, and TSINGSHAN. Upon arrival, each batch undergoes PMI and related inspections. MTSCO employs a secondary verification process to minimize the risk of material mix-ups.
· Production Process Traceability: From laser welding, cold drawing, and bright annealing to plastic encapsulation, each process is supervised by the QC team and documented with photographs. MTSCO ensures traceability of manufacturing records through process card management.
· 100% Pre-shipment Inspection: Finished products must undergo inspections including appearance, dimensional checks, PMI, ET, and pressure testing. MTSCO also accepts third-party inspections by SGS, TÜV, and BV to facilitate project acceptance.
