Buttweld Pipe Fittings Manufacturer & Supplier in India

Q: What are Buttweld Pipe Fittings?

Buttweld Pipe Fittings are pipe fittings joined to pipes by butt welding their beveled or plain ends. They form strong, leak-proof joints and are manufactured as per ASME B16.9 in materials like carbon steel, stainless steel, alloy steel, and special alloys.

Q: What is the size range for butt weld fittings?

Buttweld fittings are available in sizes from 1/2 inch to 72 inch (NPS) or DN15 to DN1200. Wall thickness ranges from Schedule 5S to Schedule 160 and XXS depending on application requirements.

Q: What is the difference between seamless and welded buttweld fittings?

Seamless buttweld fittings are manufactured without a weld seam and provide higher strength for high-pressure applications. Welded buttweld fittings are made from welded pipes and are more economical for low to medium pressure systems.

Q: Which industries use butt weld fittings?

Butt weld fittings are widely used in oil and gas, petrochemical, chemical processing, pharmaceutical, power generation, shipbuilding, water treatment, food processing, cement, and automobile industries.

Q: Are EIL approved buttweld fittings available?

Yes, Amardeep Steel Centre supplies EIL approved buttweld pipe fittings that meet Engineers India Limited specifications for use in government and critical infrastructure projects.

What Are Buttweld Pipe Fittings?

Buttweld Pipe Fittings (also spelled butt weld fittings) are pipe fittings that are joined to pipes by butt welding their beveled or plain ends. The fittings are aligned end-to-end with the pipe and welded to form a strong, leak-proof joint. Unlike socket weld fittings, which are limited to NPS 2" and below, butt weld fittings are available in a wide size range from 1/2" to 72". They are manufactured in seamless and welded construction and are suitable for high-pressure, high-temperature critical applications.

These fittings are subject to high pressure for critical applications and can be manufactured in various grades of Stainless Steel, Carbon Steel, Alloy Steel, and special alloys such as Duplex, Nickel Alloys, and Copper-Nickel, making buttweld fittings ideal for demanding industrial environments.
