ANSI B16.9 BW (Butt Weld) Pipe Fittings are high-quality, durable components designed to connect pipes in a wide variety of industrial piping systems. This standard primarily covers welded and seamless wrought steel fittings, including Elbows, Tees, Reducers (Concentric and Eccentric), and Caps. Shanxi Xinshunda Flange Manufacturing Co., Ltd. manufactures these fittings using premium-grade steel plates and seamless pipes, ensuring exceptional strength and complete compliance with ANSI B16.9 dimensional standards. Our advanced forming and welding technologies guarantee a perfect match with your pipelines, providing a robust, leak-proof, and permanent connection. Comprehensive Mill Test Reports and certifications are provided with every shipment to ensure total quality assurance.
Production Details
Our ASTM A193 bolts are produced using state-of-the-art CNC machinery to ensure every thread and hexagonal head meets precise engineering drawings. The raw materials undergo strict chemical composition analysis before entering the production line. Each fastener is subjected to rigorous surface inspection to ensure the absence of defects such as cracks, laps, or improper coating. The dimensional accuracy is verified using advanced measuring instruments, ensuring a perfect match with your mating flanges.
Product Properties and Application
Product Properties
Exceptional Strength & Durability: Designed to withstand high pressures and extreme temperatures, ensuring a long service life in demanding environments.
Smooth Fluid Flow: The seamless internal bore and precise curvature minimize flow resistance, turbulence, and potential material buildup.
Superior Weldability: The precisely machined beveled ends allow for full-penetration welding, creating a monolithic and incredibly strong joint.
Versatile Applications: Suitable for a wide range of piping configurations, easily adapting to various pipeline layouts and directional changes.
Application
ANSI B16.9 Butt Weld Pipe Fittings are extensively used in industries requiring robust and reliable piping networks. They are the standard choice for Oil & Gas Pipelines, Petrochemical Refineries, Chemical Processing Plants, and Power Generation Facilities (including nuclear and thermal). Additionally, they are widely used in Shipbuilding, Water Treatment Plants, and Heavy Machinery where high-pressure integrity is critical.

QA & QC
At Shanxi Xinshunda, we implement a rigorous Quality Control system for our ANSI B16.9 fittings. Every fitting undergoes strict dimensional inspections using calibrated templates and ultrasonic thickness gauges. We perform Hydrostatic or Pneumatic pressure tests to verify leak tightness and structural integrity. Surface defects are checked via Magnetic Particle Inspection (MPI) or Dye Penetrant Testing (DPT). Material composition is verified through spectroscopic analysis, and Mill Test Certificates (EN 10204 3.1) are provided with every shipment.
Packing, Storage, Handling and Transportation
To protect the product during transit, each fitting is carefully cleaned and the beveled ends are coated with rust-preventative oil. Smaller fittings are individually wrapped in plastic bags or bubble wrap, while larger components are stacked and securely fixed on strong plywood pallets. For international shipping, products are packed in sturdy plywood cases with ample cushioning to prevent movement and surface damage. Each package is clearly labeled with the size, material, quantity, and batch number. Store in a dry, well-ventilated area to prevent corrosion.
