What are flanges?

A Flanges is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two Flanges with a gasket between them to provide a seal.

Flanges Manufacturer India is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pump, valve, pressure vessel or any other piece of equipment. Stainless Steel Flanges, Carbon Steel Flanges & Alloy Steel Flanges provide easy access for modification, cleaning or inspection. They usually come in various shapes, Pressure Rating, Weight Chart, Dimensions, size, grades & specification with ANSI/ ASME, EN, BS, DIN standards. The Flanges are joined to each other by bolting and joined to the piping system by threading or welding and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

What is flange material?

Materials for Flanges. Pipe flanges are manufactured in all the different materials like stainless steel, cast iron, aluminium, brass, bronze, plastic etc. but the most used material is forged carbon steel and have machined surfaces.

What is flange grade?

The most common materials for pipe flanges (forged grades) are: ASTM A105 (carbon steel high temperature to match A53/A106/API 5L pipes), A350 Grades LF1/2/3 (carbon steel low temperature to match A333 pipes), A694 Grades F42 to F80 (high yield carbon steel to match API 5L pipe grades), ASTM A182 Grades F5 to F91.

What is flange standard?

A flange standard lays down the dimensions, surface finish, facing type, marking, material and technical specifications for flanges. National flange standards in Europe have largely been superseded by the European EN 1092 series.

What are the different flange standards?

Standard Flange Classification: The most common flanges pressure classes are #150, #300, #600, #900, #1500, #2500 and #3000 according to ASME designation. To other standards, as DIN, pressure classes are defined by the acronym PN, as for example, PN10, PN16, PN20, PN25, PN40, PN50, PN100, PN150, PN250 or PN420.

What is 150 flange pressure rating?

For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F. In other words, when the pressure goes down, the temperature goes up and vice versa.
