Superior Corrosion Resistance and High-Temperature Performance

Designed with grade 347/347H stainless steel, these buttweld fittings offer exceptional resistance to corrosion, making them ideal for highly corrosive and high-temperature environments. The fittings are solution annealed, ensuring enhanced durability, stability, and performance even in tough operational conditions ranging from -196C to +870C.

Comprehensive Customization

Our stainless steel buttweld fittings are available in various shapes including elbows, tees, reducers, caps, stubs, and crosses. With customizable wall thickness (1.5 mm to 12 mm), outer diameter (1/2" to 48"), and length, these fittings can be tailored to meet specific project requirements in terms of size, pressure rating, and bending radius.

Reliable Quality Assurance

Every fitting undergoes rigorous quality checks, including hydrostatic, PMI, ultrasonic, visual, and dimensional inspections. With a maximum hardness of 201 HB and comprehensive surface treatments like pickling, passivation, and polishing, our fittings deliver reliable performance with compliance to stringent ASME standards and specifications.

FAQ's of Stainless Steel Buttweld Fittings 347:

Q: How are Stainless Steel Buttweld Fittings 347 manufactured?

A: These fittings are produced using cold or hot forming processes, followed by either seamless or welded construction methods. Each fitting is solution annealed and undergoes surface treatments such as pickling, passivation, or polishing for enhanced corrosion resistance and longevity.

Q: What benefits do 347/347H stainless steel buttweld fittings offer for high-temperature applications?

A: The 347 and 347H grades contain stabilized chromium-nickel steel, providing excellent resistance to intergranular corrosion and oxidation. This makes them suitable for operating temperatures up to 870C, ensuring reliability and mechanical strength under thermal stress.

Q: When should I use bevelled versus plain end fittings?

A: Bevelled ends are typically preferred for welded connections, allowing for a deeper, more secure weld in high-pressure pipelines. Plain ends may be chosen for lower-pressure applications or where mechanical joining methods are preferred. Selection depends on your specific welding and installation requirements.

Q: Where are these fittings commonly used?

A: They are widely used in industries such as oil & gas, chemical processing, petrochemical plants, and power generation. The fittings are particularly suitable for environments with aggressive chemicals or high temperatures due to their robust corrosion resistance and temperature tolerance.

Q: What inspection processes assure the quality of these fittings?

A: Every fitting undergoes comprehensive testing, including hydrostatic pressure tests, Positive Material Identification (PMI), ultrasonic non-destructive testing, visual inspections, and dimensional verification, ensuring each product meets ASME and client specifications.

Q: How customizable are these buttweld fittings in terms of size and pressure rating?

A: The fittings offer a range of wall thicknesses (1.5 mm to 12 mm), outer diameters (1/2" to 48"), and pressure ratings from Sch 10S to Sch XXS and custom options. Length and bending radius can also be customized as per ASME B16.9 or project requirements.
