This batch of ASTM B444 UNS N06625 pipe nipple is made from seamless nickel alloy tube, ASTM B444 Grade1 (Alloy 625), dimensionally controlled under ASME B36.19 and ASME B36.10. The order includes two end styles: PE/TE NPT plain-by-NPT threaded ends and BBE bevel both ends, in 1/2 inch and 1 inch sizes, all Sch 80 wall thickness, with finished lengths of 4 inches and 8 inches. Different end preparations let contractors directly match threaded instrument taps or butt-weld spool connections without extra adaptors.
Every ASTM B444 UNS N06625 pipe nipple passes full LPE liquid penetrant examination to catch surface cracks after threading and bevel machining. Beyond surface inspection, 100% PMI positive material identification is performed on each unit, with formal test reports listing measured values of Cr, Ni, Mo and Cb/Nb to confirm alloy composition. All nipples comply with NACE MR 0175/0103, making them fit for sour service where hydrogen sulfide corrosion control is critical.
Material traceability stays intact through production, inspection and packing. Each ASTM B444 UNS N06625 pipe nipple carries permanent marking tied to heat records and inspection certificates, so the end-user can audit material and test data easily. Our team cross-checked thread profile and bevel angles against project drawing before shipment, to eliminate fit-up issues during site installation.
Haihao Group supplies precision machined nickel alloy pipe nipples for offshore and chemical piping projects across Southeast Asia. We produce custom-length ASTM B444 UNS N06625 pipe nipple with threaded, plain or bevel ends, complete with PMI and LPE reports for sour service specifications.
