Your most trusted one-stop Steel butt welding pipe fittings manufacturer
Product Categories
BAFAW manufactures steel butt welding pipe fittings for high-pressure and large-diameter pipeline systems. Each fitting is produced from ASTM A234 WPB / A403 / A420 materials, formed and heat-treated according to ASME B16.9 standards. All products are inspected for wall thickness, ovality, and weld integrity to ensure precise fit and long-term reliability.
Supports Third-party inspection (RT, UT, PT, MT)
Products Tested Under ASME B16.9 / MSS-SP-75 / ASTM A234 Standards
Manufacturing Capability
BAFAW integrates forging, machining, and surface treatment in one facility to ensure full process control. All fittings are produced with precision tools, experienced technicians, and standardized procedures—so every batch meets the same performance standards.

Every order follows strict inspection—from raw material testing to dimensional and pressure checks. BAFAW’s QC team issues inspection reports for each batch, ensuring traceability and compliance before shipment.
FAQ About Steel butt welding pipe fittings
Our fittings comply with ASME B16.9, MSS-SP-75, and DIN 2605/2615.
Every fitting is inspected for dimensional tolerance, wall thickness, and bevel angle to meet project specifications.
We manufacture with ASTM A234 WPB (carbon steel), A403 WP304 / WP316 (stainless steel), and A420 WPL6 (low temperature steel).
All materials include EN 10204 3.1 certificates with heat number traceability.
Each fitting is hot-formed and normalized to refine grain structure, then beveled at 37.5° ± 2.5° for accurate weld fit-up.
Surfaces are checked for defects using PT (penetrant) and MT (magnetic) testing before packing.
BAFAW controls outside diameter ±1%, wall thickness ±12.5%, and center-to-end ±1.5 mm, fully complying with ASME B16.9 dimensional standards.
Yes. Depending on project needs, we perform ultrasonic (UT), radiographic (RT), or hydrostatic tests, following ASME Section V guidelines.
Inspection reports can be issued by SGS, BV, or TUV upon request.
We supply fittings up to DN1200 (48″), covering elbows, reducers, tees, and caps.
Special sizes can be custom-forged or cold-formed to match project drawings.
Regular orders ship in 25–30 days, while stock sizes (≤12″) are ready within 7–10 days.
Urgent projects can be prioritized with split shipment arrangements.
All forming dies and bevel angles are CNC-controlled for consistency.
Before shipment, every fitting is 100% visually inspected and randomly checked for roundness ≤1.5% deviation to ensure perfect alignment during field welding.
