A blind flange is a solid disk used to block off a pipeline or to create a stop. It is machined in the same manner as a regular flange with the mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that a blind flange has no opening to allow fluid to pass through. The blind flange can be inserted between two open flanges and used to block off the flow of liquid through a pipeline.

Without the blind flange it would be difficult to perform maintenance or repairs on a pipeline. The flow would need to be shut off at the nearest valve, which could be miles away from the repair area. Valves are also very expensive and are prone to sticking. The blind flange is a much more cost efficient way of sealing a pipe.

China Blind Flange Manufacturer Yaang supplies ASME B16.5 ASTM B564 Inconel 718 Blind Flange, 4 Inch, Class150.

Inconel 718 Blind Flange is a bore-less pipeline flange welded to end of the pipe in order to terminate the pipeline. Blind Flange is used to terminate the pipeline. It is bolted together with a mating flange with corresponding flange facing with a sealing gasket to provide effective leak proof joint.

Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy also displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures. This nickel alloy is used from cryogenic temperatures up to long term service at 1200° F. One of the distinguishing features of Inconel 718’s composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling. The addition of niobium acts with the molybdenum to stiffen the alloy’s matrix and provide high strength without a strengthening heat treatment. Other popular nickel-chromium alloys are age hardened through the addition of aluminum and titanium. This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition. This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution-control equipment, and nuclear reactors.

In what applications is Inconel 718 used?

• Chemical processing
• Aerospace
• Liquid fuel rocket motor components
• Pollution-control equipment
• Nuclear reactors
• Cryogenic storage tanks
• Valves, fasteners, springs, mandrels, tubing hangers
• Well head completion equipment and blow out preventers (BOP’s)
• Gas turbine engine parts

What are the characteristics of Inconel 718?

• Good mechanical properties – tensile, fatigue and creep-rupture
• Yield tensile strength, creep, and rupture strength properties are exceedingly high
• Highly resistant to chloride and sulfide stress corrosion cracking
• Resistant to aqueous corrosion and chloride ion stress corrosion cracking
• High temperature resistant
• Age-hardenable with a unique property of slow aging response that permits heating and cooling during annealing without the danger of cracking.
• Excellent welding characteristics, resistant to postweld age cracking

A Blind flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened.

Blind Flange is commonly used in petrochemical, pipe engineering, public services & water works.
