Products – Flanges, Pipe Fittings & Gaskets
Our Products
Complete range of industrial pipe fittings and flanges, manufactured to international standards. All materials fully traceable with mill test certificates.
YAJIADA’s product program spans six lines: ASME B16.5 flanges, ASME B16.9 butt-weld fittings, ASME B16.11 socket-weld and threaded forged fittings, ASME B16.20 and B16.21 gaskets, pipe unions and nipples, and custom sight-glass flow indicators. The catalog covers more than 2,000 SKUs in carbon steel (A105, A234 WPB), stainless steel (A182 F304/F316, A403 WP316L), low-temperature (A350 LF2, A420 WPL6) and alloy grades.
Every item is manufactured to ASME, EN 1092, DIN, JIS and GB standards, with EN 10204 3.1 mill test certificates and optional SGS, BV or TUV third-party inspection. Stock items ship within 7 days; custom orders are delivered in 15-30 days. Material traceability runs from heat number through final export packing, so every fitting can be traced back to its original melt.
