Cangzhou Xinghui Pipeline Equipment Co., Ltd. specializes in the production and supply of ASTM A234 WPB seamless carbon steel butt-weld elbows, fully compliant with ASME B16.9 specification standards. As a professional pipe fitting manufacturer, we focus on high-pressure pipe fittings applied for process and industrial pressure piping systems. This series of elbows is designed for butt-weld connection with carbon steel pipes to change pipeline direction. Adopting integral seamless hot forming technology, the finished products have no internal welding seams, effectively avoiding pipeline leakage, structural deformation and stress damage during long-term service.
All A234 WPB elbows are processed by mature hot pushing forming technology, ensuring consistent wall thickness, smooth inner and outer surfaces, and strict dimensional tolerance compliance. The pipe end bevels are precision-machined to standard welding angles, guaranteeing perfect joint alignment and full penetration during field welding, which greatly enhances pipeline structural integrity and sealing performance. We supply complete specifications including 45°, 90°, 180° bending angles, with both long radius and short radius types available. Standard and custom non-standard sizes are all acceptable to meet diverse project requirements.
We implement strict full-range quality control from raw material incoming inspection to finished product delivery. Each batch undergoes rigorous testing, including dimensional inspection, chemical composition verification, mechanical property detection and full-scale NDT non-destructive testing. All raw materials originate from qualified steel mills, ensuring stable tensile strength, hardness and pressure resistance. Zero internal defects such as microcracks and inclusions are guaranteed, making the fittings adaptable for medium and high-pressure industrial piping working conditions.
Featuring stable mechanical performance, excellent weldability and high cost performance, our A234 WPB carbon steel elbows are widely adopted in petrochemical, thermal power, natural gas transmission and municipal piping projects. Cangzhou Xinghui Pipeline Equipment Co., Ltd. supports standard size bulk supply and non-standard customized processing according to client drawings. All products are packed with export standard and equipped with complete inspection documents, delivering reliable piping solutions for global industrial clients.
Our A234 WPB seamless butt-weld elbows cover complete specifications. Available in 45°, 90°, 180°, long radius LR and short radius SR types. Sizes range from 1/2” to 48”, wall thickness conforms to STD, XS, XXS and various schedule standards. Custom dimensions can be offered according to clients’ drawings. All items comply with ASME B16.9 for butt-weld piping projects.
