Product introduction
Product Description
76mm To 660mm HFW ERW Pipe For Oil Field Auxiliary Pipeline Project is high-frequency straight seam welded line pipe specially customized for oil field auxiliary supporting pipeline systems, covering full outer diameter range of 76mm to 660mm. It is manufactured strictly in accordance with API Spec 5L, GB/T 3091, EN10217 standards, adopting L245, X42, X52, X56M, X60M petroleum dedicated low carbon pipeline steel, applicable to oilfield water injection, crude oil gathering, associated gas delivery, cooling water, well site support and other auxiliary medium-low pressure pipeline projects.
Adopting mature HFW high-frequency induction solid-state welding process, the weld achieves complete metallurgical fusion with base metal, equipped with online internal & external flash removal and weld normalization stress relief heat treatment to eliminate welding residual stress. All finished pipes pass 100% full-length hydrostatic tightness test and full weld ultrasonic/eddy current non-destructive inspection, with smooth burr-free inner wall to reduce medium transmission resistance and avoid wax, sediment accumulation inside pipes. Multiple professional oilfield anti-corrosion treatments including single/double layer FBE, 3PE composite anti-corrosion, internal epoxy coating and hot dip galvanized are optional, adapting to desert saline soil, coastal oilfield salt fog, swamp and other harsh oilfield geological environments. We support PSL1/PSL2 two quality grades and customized -20℃/-40℃ low-temperature Charpy impact performance, stable batch quality and complete petroleum industry certification documents, being reliable matching pipe material for global onshore oilfield auxiliary pipeline EPC projects.

2. Core Product Advantages
2.1 Full 76–660mm Caliber Series, One-Stop Matching Oilfield Auxiliary Pipeline
Covers all commonly used medium and large diameter specifications for oil field water injection, gathering and well site auxiliary pipelines, fully compatible with API standard oilfield elbows, tees, flanges and pipe fittings. Oilfield contractors can complete all caliber centralized procurement from single factory, simplify multi-supplier logistics coordination, reduce project procurement cycle and comprehensive supporting costs, suitable for large-scale oilfield development batch construction.
2.2 API 5L Petroleum Dedicated Steel, Adapt To Complex Oilfield Working Conditions
Adopt L245, X series TMCP controlled rolling pipeline steel with strictly controlled low carbon, sulfur and phosphorus impurity content, uniform fine grain internal structure. It has balanced strength, toughness and anti-fatigue performance, resisting long-term alternating pressure impact of oilfield injection and gathering pipelines. PSL2 grade provides stricter chemical composition and dimensional tolerance control, meeting high-standard oilfield project acceptance requirements. Customized low-temperature impact performance solves brittle fracture risk of pipelines in northern cold oilfields.
2.3 Advanced HFW Welding + Weld Normalization, Zero Leakage For Oilfield Medium Transmission
Flux-free high-frequency induction concentrated heating welding forms narrow heat-affected zone without coarse grain deterioration. Online normalization heat treatment eliminates welding residual stress, effectively avoiding weld cracking under long-term underground soil stress and medium pressure. 100% full-length hydrostatic tightness test + full weld ultrasonic scanning NDT completely eliminates hidden leakage hazards of crude oil, natural gas and injection water pipelines, improving oilfield operation safety.
2.4 Smooth Inner Wall, Reduce Oilfield Transmission Energy Consumption
Online mechanical complete removal of internal welding flash forms flat smooth inner surface, greatly lowering friction resistance of crude oil, water and gas medium. It prevents paraffin wax, mineral sediment adhesion and pipeline blockage common in oilfield gathering pipelines, reduces regular pipeline cleaning frequency and long-term pumping energy consumption of oil stations.
2.5 Professional Oilfield Graded Anti-Corrosion Customization For Harsh Geology
Hot dip galvanized: For overhead well site auxiliary pipelines, resist atmospheric corrosion
3PE three-layer anti-corrosion: Conventional buried oilfield pipelines, strong resistance to soil electrochemical corrosion and mechanical scratch
Double layer FBE coating: High salt content desert, coastal saline oilfield, superior acid and alkali corrosion resistance
Internal epoxy lining: For injection water pipelines, prevent medium scaling and pipe inner wall corrosion, extend pipeline service life up to 40–50 years
