从China供应商批发进口90 45 Degree Carbon Steel Elbow Butt Welding — FOB条款

The 90 and 45 degree carbon steel elbow is a butt-welding pipe fitting manufactured to ASME B16.9, GB/T 12459, DIN, JIS, or BS standards, with wall thickness coverage from SCH10 through SCH160 including STD, XS, and XXS schedules. Hebei Borun Steel Trade offers these elbows in carbon steel grades A234 WPB, 20G, A105, and Q235A/B, as well as alloy grades including ASTM A420 WPL6, ASTM A234 WP5, WP11, and WP12. Sizes range from 1/2 inch to 48 inches nominal pipe size, with seamless and welded fabrication types both available to suit different pressure ratings and cost constraints in oil, chemical, electrical, and machinery applications.

Carbon steel elbows in the A234 WPB specification conform to ASTM requirements for wrought carbon steel fittings of seamless and welded construction, with chemical limits of 0.30% carbon maximum, 0.29-1.06% manganese, and specific residual element controls to ensure weldability and notch toughness. The 20G grade is a Chinese boiler steel with enhanced elevated-temperature properties, while A105 is a forging specification typically used for smaller forged fittings rather than wrought elbows; buyers should clarify which grade applies to their specific size and schedule requirement. Surface preparation includes blasting and oil, or black paint per customer request, with wooden case or pallet packaging selected to prevent ovality distortion during ocean transit. Alloy grades WP5, WP11, and WP12 are chrome-molybdenum steels for elevated temperature and corrosion-resistant service, with distinct welding procedures requiring post-weld heat treatment.

The butt-welding configuration provides full penetration joint strength when paired with matching pipe schedules, making these elbows suitable for high-pressure hydrocarbon service, steam lines, and process piping in accordance with ASME B31.3. Importers in the oil and chemical sectors typically require full traceability documentation including mill test certificates, heat treatment records, and NDE reports for critical service. Hebei Borun Steel Trade operates from Cangzhou, Hebei Province, a geographic centre of Chinese pipe fitting production with established supply chains for raw material plate and forging billets. Buyers should confirm stock availability against their exact schedule and standard requirements, as the wide grade and standard offering implies significant SKU variety that may affect delivery timing.

Hebei Borun Steel Trade Co., Ltd is located at Room 1208, Huashang International Building on Beijing Road in Yunhe District, Cangzhou, Hebei Province, China. The supplier holds a harbor trust tier, which represents basic verification without implication of quality system certification or financial standing. The response rate is recorded at 0.00% with zero average response hours, suggesting that platform-based enquiry channels may not be actively monitored. Buyers should seek direct contact through telephone or email and establish communication protocols before committing to orders.

Cangzhou is recognised as China's principal manufacturing cluster for carbon steel pipe fittings, with hundreds of producers ranging from integrated mills to trading companies, and Hebei Borun positions within this ecosystem as a steel trade specialist. The listing provides no information on in-house manufacturing assets, inspection laboratories, or API/ISO certifications that would distinguish factory from trader. Buyers requiring project-specific quality plans or third-party witnessed testing should confirm capability and accreditation status directly. The proximity to Tianjin Port (approximately 90 km) offers potential logistics advantages for consolidated export shipments.
