A403 WP304/304L Seamless Butt Weld Fittings Shipped to Russia
Process piping installations in Russia often require matched sets of stainless steel buttweld fittings to handle corrosive process media. Haihao Group has finished manufacturing and shipment of A403 WP304/304L seamless fitting packages for a Russian industrial piping project. This batch combines reducing tee, eccentric reducer and 45° long radius elbow, all built to ASME B16.9 dimensions in SCH40S wall thickness.

The A403 WP304/304L seamless fitting set includes an 8″ x 6″ seamless reducing tee, a 6″ x 3″ seamless eccentric reducer and a 3″ long radius 45° elbow. The dual-grade WP304/304L stainless steel brings the benefits of low carbon content, which minimises intergranular corrosion risks after field welding. Every A403 WP304/304L seamless fitting is seamless formed, with full dimensional inspection before packing.
Many Russian plant contractors prefer A403 WP304/304L seamless fitting for chemical and general corrosive piping systems. The eccentric reducer helps avoid trapped liquid in horizontal pipe runs, while the reducing tee supports branch connections, and the 45° LR elbow creates gentle flow turns to reduce turbulence. All three fitting types follow ASME B16.9, making them fully compatible with standard stainless pipe on site.
Our quality team verified material identification and end preparation for each component. We supply A403 WP304/304L seamless fitting with full material test certificates, supporting local technical acceptance requirements in Russia. Haihao can also produce additional stainless fittings in custom sizes and schedules for follow-up project phases.
