Manufacturing Capabilities
Manufacturing Processes
Seamless (SMLS): For high-pressure, critical fluid transmission.
ERW (Electric Resistance Welded): Precision-welded for structures and standard pressure lines.
LSAW / SSAW: Large-diameter welded pipes for long-distance pipelines and heavy piling.
Advanced Coating & Anti-Corrosion
Anti-Rust Options: Light anti-rust oil or black varnish for standard transit.
Galvanizing: Heavy-duty Hot-Dip Galvanizing (HDG) for atmospheric humidity resistance.
Pipeline Protection: 3LPE (3-Layer Polyethylene), 3LPP, and Fusion Bonded Epoxy (FBE) for underground and marine environments.
Quality Assurance
Quality control plays a critical role in ensuring that every carbon steel pipe meets customer expectations and applicable standards.
In-House Laboratory:
Chemical composition analysis (Spectrometer), tensile strength, yield strength, and elongation testing.
100% Non-Destructive Testing (NDT):
Hydrostatic pressure testing, Ultrasonic testing (UT), and X-ray weld seam examination.
TPI Partners:
Regularly cooperating with SGS, Bureau Veritas (BV), TÜV, and Intertek for pre-shipment verification.
Every project has unique technical requirements. In addition to standard products, we provide customized solutions that help customers reduce processing time and simplify procurement.
Available customization services include:
1.Custom outer diameters and wall thicknesses
2.Non-standard lengths
3.Threaded or beveled pipe ends
4.Surface coatings and corrosion protection
5.Laser marking or identification
6.OEM branding
7.Drawing-based fabrication
8.Project-specific packaging
Packaging
Bundling:
High-tensile steel strapping with protective lift slings for secure port handling.
01
End Protection:
Heavy-duty plastic/rubber pipe caps to prevent bevel damage and debris entry.
02
Moisture Barrier:
Waterproof plastic wrapping and woven sheets to combat high humidity during Southeast Asian transit.
03
Loading Optimization:
Professional container blocking, bracing, and nesting to minimize shipping costs and prevent shifting.
