Description

Stainless Steel Weld Tees

Stainless Steel Weld Tees manufactured by Stainless Steel Fittings India are high-integrity forged pipe fittings used to branch or combine flow at 90° in stainless steel piping systems. Produced to ASME B16.11 and available as equal tees and reducing tees with socket weld (S/W) or screwed / threaded ends, our SS weld tees deliver leak-proof joints, outstanding corrosion resistance and long service life in high-pressure and high-temperature service. Priced from US$8.90 per kg, they are stocked in grades 304, 304L, 316 and 316L and can be supplied in duplex and nickel alloys on request.

Types of Stainless Steel Weld Tees

• Equal Tee – all three ends of the same nominal bore.
• Reducing Tee – branch outlet smaller than the run.
• Socket Weld Tee – recessed sockets for pipe insertion and fillet welding.
• Threaded / Screwed Tee – NPT / BSP threads for mechanical, non-welded joints.

Features & Advantages

• Leak-proof, high-pressure socket weld joints
• Superior corrosion, oxidation and scaling resistance
• Forged construction for high strength and dimensional accuracy
• Smooth bore for minimal flow turbulence and pressure drop
• Supplied with EN 10204 3.1 material test certificates

Applications

Oil & gas, petrochemical and chemical processing, refineries, power and nuclear plants, fertilizer and paper mills, pharmaceutical, shipbuilding, desalination, water treatment and instrumentation piping.

Stainless Steel Weld Tees – Frequently Asked Questions

1. What is a stainless steel weld tee?

A stainless steel weld tee is a forged pipe fitting with three openings arranged in a T shape, used to branch or combine flow at 90 degrees in a stainless steel piping system. It is joined by socket welding or threading.

2. Which standards do your SS weld tees conform to?

Our stainless steel weld tees are manufactured to ASME B16.11, with reference to MSS-SP-79, MSS-SP-83 and BS 3799 for forged socket weld and threaded fittings.

3. What sizes of stainless steel weld tees are available?

Standard sizes range from 1/2 inch NB to 4 inch NB (15 NB to 100 NB). Larger and custom sizes can be produced on request.

4. What pressure classes do you offer?

We offer class 3000#, 6000# and 9000# (LBS) ratings, selected according to the working pressure of your piping system.

5. What is the difference between an equal tee and a reducing tee?

An equal tee has all three ends of the same nominal size, while a reducing tee has a branch outlet smaller than the run, used to connect a smaller line into a larger one.

6. Which stainless steel grades do you supply?

We stock ASTM A182 grades F304, F304L, F316 and F316L, and can supply 304H, 316H, 316Ti, 321, 347, 904L, duplex and nickel alloys on request.

7. What end connections are available?

SS weld tees are available with socket weld (S/W) ends and screwed or threaded ends in NPT, BSP or BSPT.

8. What is the price of stainless steel weld tees?

Our stainless steel weld tees start at US$8.90 per kg. Final pricing depends on grade, size, class and order quantity.

9. Are these fittings forged or seamless?

They are forged fittings, which gives them high mechanical strength, a dense grain structure and excellent dimensional accuracy.

10. What is the difference between a socket weld tee and a buttweld tee?

A socket weld tee has recessed sockets into which the pipe is inserted and fillet welded, ideal for small-bore high-pressure lines, whereas a buttweld tee is welded end to end and suits larger diameters.

11. Which industries use stainless steel weld tees?

They are used in oil and gas, petrochemical, chemical, refinery, power, nuclear, fertilizer, paper, pharmaceutical, shipbuilding and water treatment industries.

12. Do you provide material test certificates?

Yes. Every consignment is supplied with EN 10204 3.1 mill test certificates confirming chemical composition and mechanical properties.

13. What surface finish is provided?

Standard finishes include pickled and passivated; polished or electro-polished finishes are available on request.

14. Can you supply special grades such as duplex or nickel alloy?

Yes. We manufacture tees in duplex, super duplex, Inconel, Monel, Hastelloy, Alloy 20 and titanium to order.

15. How are the fittings marked for traceability?

Each fitting is marked with the manufacturer, material grade, heat number, size and pressure class for full traceability.

16. Do you export and how are the products packed?

Yes, we export worldwide. Fittings are packed in wooden boxes or cartons to ensure safe, damage-free international delivery.

17. What is the minimum order quantity for SS weld tees?

There is no rigid minimum. We serve both small trial orders and bulk project requirements. Contact us for a tailored quote.
