At Solitaire Fittings, we are a trusted SMO 254 Buttweld Fittings Manufacturer & Supplier in India, delivering high-quality pipe fittings for various industrial applications. Our Stainless Steel SMO 254 Buttweld Fittings are widely used in industries such as chemical processing, desalination plants, offshore oil & gas, power generation, and marine engineering because of their excellent corrosion resistance and durability.
SMO 254 (UNS S31254) is a super austenitic stainless steel grade designed with a high level of molybdenum and nitrogen. This unique composition gives SMO 254 Buttweld Pipe Fittings superior resistance to pitting, crevice corrosion, and stress corrosion cracking, even in highly aggressive chloride environments.
As one of the leading SMO 254 Buttweld Pipe Fittings Manufacturer in India, we ensure our fittings meet international standards like ASTM A403, ANSI B16.9, ASME, and DIN.
What are Stainless Steel SMO 254 Buttweld Fittings?
SMO 254 Buttweld Fittings are pipe fittings made from SMO 254 stainless steel, designed to connect, change direction, or modify the flow of liquids and gases in piping systems. They are joined by a buttwelding process, which provides strong, leak-proof, and long-lasting joints.
Key types of SMO 254 stainless steel pipe fittings include:
- SMO 254 Elbows (90° & 45°) – For changing pipe direction.
- SMO 254 Tees (Equal & Reducing) – For dividing or combining pipe flows.
- SMO 254 Reducers (Concentric & Eccentric) – For connecting different pipe sizes.
- SMO 254 Caps & Ends – To seal pipelines.
- SMO 254 Stub Ends – Used with lap joint flanges.
- SMO 254 Cross Fittings – For four-way connections.
These fittings are preferred because they provide smooth flow inside pipelines, minimize pressure drops, and ensure maximum mechanical strength.
Key Features of SMO 254 Buttweld Fittings
- High Corrosion Resistance – Outstanding resistance to pitting, crevice, and chloride-induced corrosion.
- Excellent Strength – Higher mechanical strength than standard stainless steel grades.
- Long Service Life – Designed to withstand aggressive chemical and marine conditions.
- High Weldability – Easily weldable with standard welding methods.
- Cost-Effective Alternative – Often used as a cheaper substitute to titanium and nickel alloys in seawater applications.
Available Types of SMO 254 Buttweld Fittings
- SMO 254 Elbow (90°, 45°, Long Radius, Short Radius)
- SMO 254 Tee (Equal & Reducing Tee)
- SMO 254 Reducer (Concentric & Eccentric Reducer)
