304 Stainless Steel Butt Weld 90 LR Elbow MSS SP-43 Seamless

Product Specification

304 Stainless Steel Butt Weld 90 LR Elbow MSS SP-43 Seamless

1. Product Description 

The stainless steel butt welding elbow is a precision‑engineered pipe fitting designed for permanent installation in high‑integrity piping networks. Manufactured using hot extrusion, cold forming, or forging techniques, the product features a precision‑machined beveled end that enables full‑penetration butt welding, delivering a joint with mechanical properties equivalent to the pipe itself. The fitting is produced from premium quality stainless steel, including 304/304L, 316/316L, 321, 347, and duplex grades, ensuring outstanding resistance to corrosion, pitting, and high‑temperature oxidation. Each batch undergoes stringent quality testing to guarantee compliance with international standards and customer specifications.

2. Product Applications

The butt welding elbow is widely employed across industries where pipeline directional changes are required under demanding service conditions. Representative applications include:

• Petroleum refining – atmospheric and vacuum distillation units, catalytic cracking, coking, and hydrotreating sections.

• Natural gas processing – gas gathering, dehydration, sweetening, and LNG liquefaction/regasification plants.

• Chemical fibre and plastics – polymerisation reactors, extrusion lines, and solvent recovery circuits.

• Pharmaceutical manufacturing – API synthesis, sterile filling, and WFI (water for injection) distribution systems.

• Brewing and distilling – mash transfer, fermentation, and product routing pipelines.

• Mining and mineral processing – slurry lines, tailings disposal, and reagent feed systems.

• District heating and cooling – buried and above‑ground thermal networks with expansion loops.

• Hydrogen and new energy – hydrogen transmission, fuel cell feed lines, and green ammonia plants.

• Ship repair and offshore platforms – firewater, bilge, ballast, and crude oil washing systems.

​

​3. Product Advantages

• Material authenticity guaranteed – each heat is verified by PMI testing; full mill test reports (MTR) are provided with every shipment.

• Broad standard coverage – products are manufactured and certified to satisfy ASME, EN, JIS, GOST, and Chinese standards, simplifying global project sourcing.

• Flexible manufacturing – we accept small‑batch custom orders (including non‑standard angles, radii, and special alloys) with short lead times.

• Consistent wall thickness – advanced forming processes minimise wall thinning at the intrados (inner curve), ensuring uniform pressure‑bearing capacity.

• Ready inventory – standard dimensions in 304/L and 316/L are maintained in large stock, enabling 24‑48 hour dispatch for urgent requirements.

• Price competitiveness – integrated production chain from raw material to finished product reduces intermediate costs.

• Environmentally conscious – manufacturing processes are designed to minimise waste and energy consumption, with recyclable packaging materials.

• Global service network – experienced technical team provides pre‑sale consultancy, welding procedure support, and after‑sales follow‑up.
