Hastelloy Socket Weld Flanges Manufacturer and Supplier and in India

Hastelloy socket weld flanges are a type of flange made from Hastelloy alloys, known for their exceptional corrosion resistance properties. Socket weld flanges are manufactured for easy and safe connection to pipes using a socket weld joint. Hastelloy socket weld flanges are circular flanges with a bore (inner hole) that matches the outer diameter of the pipe they are attached to. They have a socket, or recessed area, at the base of the bore, where the pipe end is inserted. This socket is then fillet-welded to the pipe to produce a strong, leak-resistant connection. Various applications of hastelloy socket weld flanges where these flanges are used are pollution control, offshore and marine, semiconductor industry, petrochemical industry and many more.

Types of Hastelloy Socket Weld Flanges

They are often used in certain piping systems or equipment where a smooth, flat connection is desired. When the flanges are socket welded together, the ring gasket provides a reliable and high-pressure seal. These flanges are commonly used in applications requiring a secure and leak-free joint. When socket welded together, the tongue and groove create a secure, leak-free joint. They are often used in applications where alignment and positive sealing are critical.

  • Socket Weld Raised Face (SWRF) Flanges: These flanges have a raised face on the sealing surface, providing a ridge for better alignment and sealing when socket welded to a corresponding pipe or fitting.
  • Socket Weld Flat Face (SWFF) Flanges: SWFF flanges have a flat sealing surface, making them suitable for applications where the flange needs to be flush with the adjoining surface.
  • Socket Weld Ring Type Joint (SWRTJ) Flanges: SWRTJ flanges feature a groove machined into their faces to accommodate a metal ring gasket.
  • Socket Weld Tongue and Groove (SWTG) Flanges: SWTG flanges have a raised tongue on one flange and a matching groove on the other.
  • Socket Weld Orifice Flanges: These flanges are specifically designed for orifice meter applications, where precise flow measurement is required.

Features of Hastelloy Socket Weld Flanges

  • Hastelloy socket weld flanges offer excellent resistance to corrosion, including resistance to pitting, crevice corrosion, and stress corrosion cracking.
  • Hastelloy alloys used in socket weld flanges provide exceptional strength, allowing them to withstand high pressure and temperature conditions without deformation or failure.
  • Hastelloy socket weld flanges are designed to provide a reliable and leak-proof seal when properly welded to a matching pipe or fitting.
  • Socket weld flanges are relatively easy to install and require less preparation compared to other types of flanges.
  • Hastelloy socket weld flanges have a compact and space-saving design, making them suitable for applications with space constraints or where a sleek appearance is desired.
