Large Diameter Stainless Steel Elbow

Large Diameter Stainless Steel Elbow

Our large diameter stainless steel elbow is engineered for high-flow pipelines, power plants and process industries that require full-bore directional changes at scale. Available from 1/2 inch up to 60 inch in both seamless and welded construction, these fittings are produced to ASME B16.9 dimensions and ASTM A403 / ASTM A815 material specifications across 304L, 316L and duplex 2205 grades. Controlled wall thickness, verified roundness and precise bevel ends ensure trouble-free fit-up and welding on site.

For diameters beyond 48 inches, we maintain dedicated forming tooling and experienced welders, allowing us to deliver dependable large-bore elbows that other suppliers cannot easily produce. Every fitting is dimensionally inspected and, where required, ultrasonically checked for wall integrity before shipment. With steady inventory of common large sizes and the ability to custom-fabricate special diameters, we keep large-scale piping projects on schedule.

Production is carried out on dedicated large-diameter forming equipment by experienced operators, ensuring consistent radius and wall uniformity across every batch. Welded seams are full-penetration welded and, where specified, radiographically or ultrasonically examined. Each finished fitting is checked for roundness and bevel preparation to support fast, accurate installation and reliable long-term performance in the field.

• Duplex 2205 option combines high strength with superior corrosion resistance.
• Controlled wall thickness verified by ultrasonic measurement for consistent performance.
• Custom sizes, non-standard angles and 3D / 5D radius bends available on request.
• Ready stock of common large diameters shortens lead times for urgent projects.

Applications

These elbows are widely used across demanding industries, including:

• Oil and gas transmission pipelines
• Power generation and utility piping
• Water supply and wastewater mains
• Chemical and petrochemical process lines
• LNG terminals and large-scale infrastructure

Frequently Asked Questions

Q: What is the largest stainless steel elbow you can supply?

A: We can supply welded elbows up to 60 inches in diameter, and even larger custom sizes can be fabricated on request to meet specific project requirements.

Q: Can you provide both seamless and welded large diameter elbows?

A: Yes. Seamless elbows are typically available up to about 24–48 inches depending on grade, while welded elbows cover the full range up to 60 inches and beyond.

Q: Which standards apply to your large diameter elbows?

A: Our elbows conform to ASME B16.9 dimensions and ASTM A403 (austenitic stainless) or ASTM A815 (duplex) material specifications.

Q: Do you offer duplex 2205 in large diameters?

A: Yes, duplex 2205 is available in large diameters and is an excellent choice for high-strength, corrosion-resistant applications such as offshore and chemical service.
