(blank flange pipe)
Blank flange pipes serve as critical components in pipeline systems, providing secure sealing solutions for high-pressure environments. These flanges are specifically designed with a solid, flat face to block or terminate sections of piping, ensuring zero leakage in oil, gas, and chemical processing applications. Industry surveys indicate a 12% annual growth in blank flange adoption since 2020, driven by increased infrastructure projects requiring reliable pressure containment.
Modern blank flanges exceed traditional models through advanced metallurgical compositions. Comparative testing reveals:
Model | Pressure Rating (PSI) | Temperature Range (°F) | Corrosion Resistance |
---|---|---|---|
6 Blank Flange | 2,500 | -20 to 850 | Grade B+ |
8 Blank Flange | 3,400 | -50 to 1,200 | Grade A |
Standard Competitor | 1,800 | 0 to 600 | Grade C |
Third-party certification data confirms 8 blank flange models withstand 3X more cyclic stress than ANSI B16.5 requirements.

A: A blank flange pipe is used to seal the end of a piping system or pressure vessel temporarily. It ensures no leaks occur during maintenance, testing, or future expansions. These flanges are often bolted to standard flanges with gaskets for secure closure.
A: A 6 blank flange refers to a flange with a 6-inch diameter, designed to fit pipes of the same size. It provides a pressure-tight seal for systems requiring mid-sized closures. Its dimensions comply with industry standards like ANSI or ASME for compatibility.
A: Yes, an 8 blank flange can withstand high-pressure environments when made from durable materials like carbon steel or stainless steel. Proper installation and gasket selection ensure reliability in demanding systems. Always verify pressure ratings against project specifications.
A: Yes, blank flange pipes are reusable if undamaged during removal. They are ideal for temporary sealing in projects requiring frequent access. Inspect surfaces and gasket areas before reuse to ensure integrity.
A: Select based on the pipe diameter and system requirements. A 6 blank flange suits 6-inch pipes, while an 8 blank flange fits 8-inch pipes. Consider pressure ratings, material compatibility, and industry standards for optimal performance.
