ASTM B366 WPNCMC NACE Sour Service Fittings Shipped to Singapore Project

Haihao Group recently completed the shipment of ASTM B366 WPNCMC seamless fittings for a Singapore sour service project, including a seamless tee and a 45-degree long radius elbow in NPS 2, SCH10S. These buttweld fittings follow ASME B16.9 dimension rules and are fully built to meet NACE MR0175 / NACE MR0103 sour working conditions, a critical requirement for oil and gas piping handling corrosive media.

This batch of ASTM B366 WPNCMC fittings adopts Grade 1 material, with dedicated heat treatment to stabilize mechanical properties. Every piece undergoes 100% LPE and 100% PMI testing, and the inspection report records actual measured content of Cr, Ni, Mo and Cb/Nb elements to verify alloy composition consistency. PT examination is also performed to eliminate surface defects before release.

We mark each fitting with required identifiers: NACE, PMI and unique item codes, and label the origin as Hebei Haihao, China. For transit protection, the ASTM B366 WPNCMC tee and elbow are fitted with end caps and packed into solid wooden cases, avoiding surface scratches and thread/end damage during ocean transport to Singapore.

Many sour-gas operators in Southeast Asia look for reliable suppliers of ASTM B366 WPNCMC fittings that can combine full material traceability, third-party test records and controlled packaging. Our workshop keeps strict process control on forming, heat treatment and non-destructive testing, so these NACE-compliant nickel alloy fittings can fit directly into high-risk sour pipelines.

If you are sourcing NACE qualified Inconel 625 buttweld fittings, including tees, elbows, reducers and caps, you can send your schedule, size and inspection requirements to our engineering team for quotation and technical datasheet support.
