Sockt welding steel pipe flange

Socket Welding Steel Pipe Flange is a high-strength pipe connection component designed for small-diameter industrial pipelines, featuring a socket welding structure that inserts the pipe into the flange socket for welding, complying with ANSI/ASME, GB, or DIN international standards.

Description

Core Advantages

  • Socket welding design ensures strong connection integrity, with welds evenly distributed to minimize leakage risks in high-pressure systems.
  • Compact size saves installation space, ideal for small-bore pipelines (typically DN15-DN50) and narrow working environments.
  • Available in carbon steel, stainless steel, alloy steel materials, offering excellent corrosion resistance and pressure-bearing capacity for diverse media.
  • Complies with global standards for strong interchangeability, enabling seamless matching with international pipelines and valves.

Application Scenarios

Widely used in oil & gas, petrochemical, power generation, water treatment, and instrumentation pipeline systems. It reliably connects small-diameter pipes carrying water, steam, oil products, natural gas, and general industrial fluids, suitable for scenarios requiring compact, leak-tight, and high-pressure-resistant pipe connections.
