Custom Large Diameter Longitudinally Welded Pipe Fittings Finished and Packed for Project Delivery

Our workshop has recently completed the fabrication and packing of a batch of extra-large bore butt-weld pipe fittings, including large-radius elbows and heavy-duty tees, which are ready for onward shipment to our overseas project partner.

These non-standard large-size fittings are manufactured following ASME B16.9 specification, adopting longitudinal welding technology for big diameter production. This fabrication method is the reliable solution for sizes beyond the capacity of seamless fittings, widely applied in oil & gas transmission, thermal power, chemical and long-distance pipeline engineering.

Quality control runs through the whole production workflow: raw material inspection, forming, welding, heat treatment, NDT non-destructive testing and dimension verification. Every single piece is checked strictly to meet project technical requirements, with material test certificates (MTC) available for traceability.

For ocean transportation protection, all pipe ends are covered with durable blue plastic end caps to guard the bevel surface from scratches, dirt and moisture. The fittings are wrapped with waterproof woven fabric and secured firmly on solid heat-treated wooden pallets. Independent pallet packing prevents collision and deformation during loading, sea transit and unloading at the destination port.

We have rich experience in custom large diameter pipe fittings. Besides carbon steel, we can also fabricate stainless steel, duplex steel and alloy steel elbows, tees, reducers and caps according to customers’ drawings, special wall thickness and heat treatment requests.
