Frequently Asked Questions (FAQ)
-
Q: What makes this flange prop “non-sparking”?
A: It is manufactured from a special copper-aluminum alloy that does not produce sparks when struck or rubbed against steel or other metal surfaces. This is critical in environments with flammable gases, vapors, or dust. -
Q: What is the maximum pressure the safety clamp can handle?
A: Standard models support up to 3000 PSI. Custom higher pressure ratings can be provided upon request – please contact our sales team with your specific requirements. -
Q: Can this tool be used for all flange types (welding neck, slip-on, blind)?
A: Yes, the prop is designed to accommodate most common flange types, including weld neck, slip-on, threaded, and blind flanges, as long as the outer diameter falls within the adjustable range. -
Q: Is the clamp adjustable for different pipe thicknesses?
A: Absolutely. The clamping mechanism features a screw-adjustable gap that can be adapted to pipe walls or flange hubs up to 50 mm thick. -
Q: What certifications do your products meet?
A: Our products are manufactured under strict quality control and can meet ATEX, IECEx, or other regional standards. Certificates are available upon request. We do not include them as default to avoid false claims, but we can provide valid documentation for your project. -
Q: How do I choose the correct size for my flange?
A: Refer to the flange nominal diameter (e.g., 2", 4", 8") and match it with our size chart. For non-standard sizes, please provide the outside diameter and we will customize the prop accordingly. -
Q: What is the estimated lead time for a standard order?
A: Standard sizes are usually in stock and can ship within 7–15 days after order confirmation. Custom orders may require 20–30 days depending on complexity. -

A: Yes, we provide a 12-month warranty against manufacturing defects. Extended warranty options are available.
