- Standards: Manufactured to ASTM, API, DIN, EN, JIS, BS and GB standards as required
- Diameter range: 1/8" up to 36" (nominal)
- Wall thickness: Standard schedules from SCH5 up to XXS (extra extra strong); custom wall thicknesses available to order
- Lengths: Typical loading lengths — 8.0 m for 20' containers; 6.0–12.0 m for 40' containers (custom cut lengths available)
- Inspection & certification: Third-party inspection and certification by BV, SGS, Lloyd's, DNV, CCS and other recognized bodies (certificates available on request)
Quality & testing
Pipes are produced under controlled manufacturing processes with mechanical and chemical testing to verify compliance with specified standards. Tests commonly provided include tensile and yield strength, elongation, chemical composition analysis, hydrostatic testing and dimensional inspection. Third-party inspection and mill test certificates (MTC) can be arranged per buyer requirements.
Packaging & logistics
Pipes are bundled, protected with end caps and corrosion-inhibiting measures for export shipping. Standard export packing for container and bulk shipment handled to minimize damage during transit. Loading lengths and packing configurations are optimized for 20' and 40' container shipments.
Typical applications
- Oil and gas transmission pipelines
- Water supply and distribution
- Industrial piping and structural applications
- Onshore and offshore pipeline projects
Ordering & customization
Custom diameters, wall thicknesses, material grades and lengths can be manufactured to meet project specifications. Please include required standard (API/ASTM/EN etc.), grade, OD, wall thickness (or schedule), length, quantity and any inspection or certification requirements when requesting a quotation.
