FAQ About Screwed Pipe Fittings
BAFAW produces fittings with NPT, BSP, and BSPT threads according to ASME B1.20.1 and ISO 7/1 standards. Thread tolerance is controlled within ±0.05 mm, ensuring full interchangeability and tight sealing with global systems.
Our screwed pipe fittings are available in Class 2000, 3000, and 6000, manufactured under ASME B16.11. Each batch is pressure-tested at 1.5× the rated working pressure to ensure safe performance in high-pressure pipelines.
We manufacture in ASTM A105 (carbon steel), A182 F304/F316 (stainless steel), and A350 LF2 (low-temperature steel). These materials cover 90%+ of oil, gas, and industrial applications requiring corrosion and temperature resistance.
Threads are machined with CNC lathes using precision gauges certified per ASME B1.20.1. Each fitting undergoes 100% thread plug and ring gauge inspection to prevent leakage or mismatch during installation.
Yes. Every shipment includes EN 10204 3.1 MTC, showing chemical composition, mechanical properties, and heat numbers. We also support SGS / BV / TUV third-party inspection as requested by project owners.
Standard finishes include black oxide, zinc plating, and hot-dip galvanizing. Galvanized coating thickness is ≥70 μm, providing over 500 hours of corrosion resistance under salt-spray testing.
Dimensional accuracy is controlled within ±0.15 mm, and threads follow the ASME B1.20.1 / ISO 7-1 standards. Each fitting is verified for proper engagement depth and pitch accuracy before packaging.
Regular lead time is 25–30 days for bulk orders, 7–10 days for stock items. MOQ starts from 50–100 pcs per size, with sample production available for engineering validation before mass production.
