Blind Flanges

Our Blind Flanges feature proper bolt holes with a round plate having no center hold. Extensively employed for proper closure of the ends in the piping systems, the range of Blind Flanges is also useful in accessing a line even after its sealing has been done. Blind Flanges are offered by us in varying sizes and dimensions as per the specific requirements of the clients and in standards sizes as well. Useful for standard sized pipes that have to be reduced by threading or welding.

Materials of Construction :

• Stainless Steel
• Nickel Alloy
• Carbon Steel
• Titanium
• Aluminum
• Cast Iron
• Brass
• Bronze
• Polypropylene
• Silicone
• PVC

Information :

• When used with NPT Fittings, these are useful for testing pressure
• Blind Flanges handle the highest stress in terms of internal pressure and bolt loading
• Blind Flanges can be placed at a greater height than other flanges because the maximum stresses in them are the bending stresses at the centre

Why our Blind Flanges?

• Dimensionally accurate
• Robust construction
• Smooth finishing
• Corrosion resistant
• High stress bearing capacity
• Hard-wearing

Ideal for :

• Pipes
• Valves
