Description
Stainless Steel 90 Degree Weld Elbows
Stainless Steel Weld Elbows 90 Degree are precision pipe fittings made by SS forging or casting used to change the direction of flow by 90° in a stainless steel piping system. Manufactured by Stainless Steel Fittings India, an ISO 9001:2015 certified manufacturer and exporter with 25+ years of experience, these 90° elbows are available in both buttweld (ASME B16.9) and socket weld (ASME B16.11) configurations, in long radius (LR, 1.5D) and short radius (SR, 1D) patterns.
Produced from premium SS 304, 304L, 316, 316L, 317L, 321, 347, Duplex 2205 and Super Duplex 2507, our 90 degree weld elbows deliver excellent corrosion resistance, high-temperature performance and long, maintenance-free service life. Each elbow is pickled, passivated and supplied with an EN 10204 3.1 mill test certificate — ready for demanding oil & gas, chemical, pharmaceutical, food, marine and general process applications. Base price: US$9.20 / kg.

| Common use | Default for most piping | Congested / compact piping |
Key Features & Benefits
- Superior corrosion & pitting resistance (especially 316/316L in chloride / marine service)
- High-temperature and high-pressure capability
- Smooth full-bore weld for minimal flow restriction (buttweld)
- Fast, strong fillet-weld joints for small-bore lines (socket weld)
- Pickled & passivated for a clean, hygienic surface
- Consistent dimensions to ASME B16.9 / B16.11 tolerances
- 3.1 material test certificate traceability with every lot
Industries & Applications
Oil & gas and petrochemical piping, chemical & fertilizer processing, pharmaceutical & biotech clean piping, food, dairy & beverage processing, water treatment & desalination, power generation & boilers, shipbuilding & offshore / marine, and HVAC and general plant utilities.

Frequently Asked Questions
What is a stainless steel 90 degree weld elbow?
A stainless steel 90 degree weld elbow is a pipe fitting that changes the direction of flow by 90° and is joined to pipe by welding — as a buttweld elbow (welded end-to-end per ASME B16.9) or a socket weld elbow (inserted into a socket and fillet welded per ASME B16.11).
What is the difference between a long radius and short radius 90° elbow?
A long radius (LR) elbow has a centre-to-face radius of 1.5× the nominal diameter (1.5D) and gives lower pressure drop, so it is the default choice. A short radius (SR) elbow is 1.0× the diameter (1D), used where space is limited at the cost of higher turbulence.
What stainless steel grades are 90° weld elbows available in?
SS 304, 304L, 316, 316L, 317L, 321, 347, Duplex 2205 and Super Duplex 2507. Grade 304 suits general service; 316/316L offers superior resistance in marine, chemical and chloride environments.
Which standards do your 90° weld elbows conform to?
Buttweld 90° elbows conform to ASME B16.9 and MSS-SP-43 from material meeting ASTM A403 / ASME SA403. Socket weld 90° elbows conform to ASME B16.11.
What sizes are available?
Buttweld: 1/2″ to 48″ NB. Socket weld: 1/8″ to 4″ NB. Custom sizes on request.
What wall thickness or schedule can I order?
SCH 5S, 10S, 40S/STD, 80S/XS, 160 and XXS, matched to the connecting pipe wall thickness.
How is the price of US$9.20 per kg calculated?
US$9.20/kg is a base indicative rate for standard SS 304 buttweld elbows. Final pricing depends on grade, size, schedule, quantity and finish; cost per piece scales with elbow weight. Contact us for a firm quotation.
Are these elbows suitable for high-pressure applications?
Yes. Socket weld elbows are rated to Class 3000, 6000 and 9000; buttweld elbows are pressure-rated to match the connected pipe schedule.
Can you supply elbows with material test certificates?
Yes — an EN 10204 3.1 mill test certificate ships with every consignment. 3.2 certification and third-party inspection are available on request.
What surface finish do the elbows come in?
Pickled & passivated, polished (mirror or satin) and electropolished.
What is the typical lead time and packaging?
Stock sizes ship in 48 hours to one week; made-to-order items in 2–4 weeks. Box or wooden-case packed for safe export transit.
Do you export worldwide?
Yes — to the USA, UK, Germany, Australia, Canada, Europe, the Middle East and more, with full export documentation.
Which industries use 90° stainless steel weld elbows?
Oil & gas, petrochemical, chemical, pharmaceuticals, food & dairy, water treatment, power, shipbuilding, HVAC and general plant piping.
How do I choose between a buttweld and a socket weld 90° elbow?
Buttweld for larger-bore, high-flow lines needing a smooth full-bore weld; socket weld for small-bore (generally 2″ and below) high-pressure lines.
How do I place an order or get a quotation?
