PIPE BLIND FLANGE USES
- Isolation for Maintenance: Seals pipeline sections for repairs without system shutdown, which improves operational efficiency and reduces downtime.
- 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. Engineered Flanges. Texas Made. Job-Ready.
NEED PORTS? Choose from middle, top, or bottom ports, and socket weld or NPT vent connections.
