Single Process Introduction—Laser Welding
Laser welding is one of the key processes in 825 heat coil tube production, directly affecting weld quality, dimensional stability, and the results of subsequent processing. It is a welding method that focuses a high-energy laser beam on the metal joint area, causing the material to melt rapidly within a small area and form a weld. Compared to traditional welding, laser welding offers more concentrated heat input and faster welding speeds. MTSCO’s welded coiled tubing production process incorporates 100% laser welding, better meeting requirements for continuous length and consistent quality.
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.
Inspection Methods
The focus of pipeline inspection extends beyond dimensions to include weld integrity, pressure-bearing capacity, and material consistency. Routine inspections cover visual inspection, PMI, dimensional verification, air tightness testing, ET, and hydrostatic testing, with standard pressure at 5,000 PSI and a maximum of 15,000 PSI. MTSCO’s welded coiled tubing undergoes a comprehensive inspection process prior to shipment to ensure product quality before leaving the factory.
FAQ
Q1: What is the maximum length available?
A1: Welded coils can be less than 15,000 meters in length, with a maximum of 50,000 ft per coil. Longer continuous lengths help reduce on-site joints.
Q2: Why is traceability a key focus for projects?
A2: Because records of raw materials, production, testing, and shipping directly impact acceptance and subsequent verification. MTSCO retains test reports, test specimens, and process images to facilitate traceability.
Q3: What is the pressure testing capability for welded coils?
A3: The standard test pressure is 5,000 PSI, with a maximum of 15,000 PSI, which can also be expressed as up to 100 MPa. This is suitable for high-pressure applications with stringent requirements.
