Non-standard Blind Flanges

Non-standard blind flanges are solid, round plates custom-made to tightly seal the end of a pipe, much like a permanent cap. They are built for specific jobs where standard, off-the-shelf caps won't work.
Here is the simple breakdown of what makes them "non-standard":
• Custom Dimensions: They are precisely sized and shaped to fit unique pipe diameters or specific pressure vessel openings not covered by standard industrial sizes.
• Special Materials: They are manufactured using specific, robust materials (like strong alloys, copper, or titanium) chosen to withstand extreme conditions, such as intense heat, massive pressure surges, or exposure to dangerous chemicals.
• Unique Features: They can be made with special taps for testing pressure gauges, specific grooves for unusual seals (gaskets), or altered thickness to handle a one-off structural requirement.
• Safety Critical: They are primarily used in high-stakes industries like oil and gas, chemical processing plants, or marine engineering where preventing leaks and ensuring safety is paramount.
In short, non-standard blind flanges are tough, tailor-made metal caps used to perfectly and safely seal the end of a pipe in extreme or unique industrial environments.
