At Hebei Allland Steel Pipe Manufacturing Co., Ltd., we bridge the gap between heavy-duty steel pipe manufacturing and complex global project execution. Major EPC contractors, state-owned energy companies, and international mining giants rely on Allland to engineer, manufacture, and deliver specialized pipeline products built to withstand severe pressures, corrosive media, and demanding topographies.
Our integrated production lines produce high-grade LSAW (Longitudinal Submerged Arc Welded), SSAW (Spiral Submerged Arc Welded), ERW, and seamless casing pipes with advanced external and internal anti-corrosion coatings (3LPE, 3LPP, FBE). Whether for cross-country natural gas transmission, deepwater seawater cooling, or downhole oil extraction, Allland delivers fully compliant, certified steel pipe packages on time and within budget.
Our project footprint spans over 50 countries across the Middle East, Australia, South America, and Asia-Pacific. Explore how our custom steel pipe solutions support critical industrial sectors:
Material integrity is non-negotiable for critical infrastructure. Every steel pipe supplied for Allland project orders undergoes rigorous QA/QC inspection protocols in full alignment with international standards including API 5L, API 5CT, ASTM A252, ASTM A53, EN 10219, and ISO 3183.
We provide full material traceability with EN 10204 Type 3.1 Mill Test Certificates (MTC) for all lots. Our testing scope includes 100% Non-Destructive Testing (UT/RT), hydrostatic testing, HIC/SSCC anti-corrosion testing for sour service, and dimensional verifications. We welcome third-party inspection agencies such as SGS, BV, and Intertek to perform factory acceptance testing prior to shipment.
A : Yes. We specialize in custom steel pipe manufacturing, providing non-standard outer diameters (OD), heavy wall thicknesses, custom lengths, beveling, and tailored shoulder ends for quick-coupling systems across mining and industrial projects.
A : Absolutely. Allland offers one-stop pipeline supply chain solutions. We provide factory-applied 3LPE, 3LPP, FBE, and HDG coatings along with compatible butt-weld fittings, grooved couplings, and flanges to ensure seamless field installation.
A : Pipes designated for sour service (such as API 5L Annex H / NACE MR0175) undergo vacuum degassed steel refining, precise chemistry control (low S and P content), restricted hardness limits, and mandatory Hydrogen-Induced Cracking (HIC) and Sulfide Stress Corrosion Cracking (SSCC) laboratory testing.
