  • Pressure Testing: Acts as a temporary closure for hydrostatic or pneumatic tests.
  • Permanent Sealing: Used for decommissioning or abandoning pipeline sections.
  • Versatile Applications: Common in oil and gas, chemical processing, power generation, and water treatment industries.

SPECIFICATIONS: Our ANSI flanges are typically manufactured with raised face or Ring Type Joint (RTJ) facing. The standard height is 1/16" for pipe caps under ASME rating 400# and 1/4" for flanges 400# and up.
