Blind Flange Fabrication

Carbon Steel, Stainless Steel and other specialty grades of metal are available.

Fabricated Flanges

Benchmark has supplied and fabricated a wide variety of piping products in support of the Oil & Gas Industry, LNG Plant Construction, Marine Services and Pulp / Paper Plants.

The variations of assemblies we have deployed are enormous, however typically a piping assemble consists of the following basic components:

Piping, Flanges, Valves, Fittings, Stud Bolts, Gaskets, Isolation Kits and Pipe Spools AKA Flanged Spools.

Blind Pipe Flange is used whenever a line must be capped of at a flange. It is good practice to install blind pipe flange at the end of header or at location where future tie-ins are anticipated.

Blind pipe flanges are also used extensively for manways, in which case a davit is recommended for ease in handling the unbolted manway cover.

Blind pipe flange is specified by ANSI B16.47.

Benchmark offers blind pipe flange in A105, A105N, SS316, SS304, A20, High Yield & Nickel Alloys. Contact US for your flange buying needs.

Canada Stainless Steel Blind Flanges

Blind Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings.

From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types.

However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure temperature applications.
