What is an ASTM A182 F304 Blind Flange?

Gandhi Metal India forges blind flanges with excellent wear resistance in multiple types and sizes. Flanges are integral components in many industries, facilitating the inspection and cleaning of piping. An ASTM A182 F304 Blind Flange is commonly used for pressure testing, sealing pressure vessels, and helping in line repairs.

It is an austenitic stainless steel with additions of chromium (18%), nickel (8%), carbon, manganese, phosphorus, silicon, and sulfur. This metallurgical profile lends these components superior strength and temperature resistance (up to 870 degrees Celsius).

Unlike a regular flange, blind ones lack a hub and get bolted instead of welding. Some applications also employ them to terminate a piping system by obstructing the flow of fluids.

Specialist in ss forged flanges and ASME SA182 plate flange

What are SS forged Flanges and ASME SA182 Plate Flanges?

Stainless Steel Forged Flanges join two machine parts to connect pipelines and deliver superior strength and mechanical properties. The forging process involves cutting and chiselling a hollow tube to avoid segregation, then rolling it into welded joints and flattening it. These fittings are durable and more corrosion-resistant than competing materials due to their lower carbon content.

Their high wear resistance helps them become less expensive after the first maintenance cycle. Their most common application is in liquid and oil pipelines in the petrochemicals industry and refineries subject to severe internal corrosion. These components boast a high tensile strength which limits deformation with time.

ASME SA182 Plate Flanges conform to the ASME SA182 specifications for forged or rolled flanges, fittings, valves, and other components that operate under high temperatures. The standard applies to piping systems and facilitates easier cleaning and inspection.

It covers guidelines for stainless steel piping components employed in pressure systems. They are the same as ASTM A182 flanges and find widespread utility in architectural and transportation-oriented applications. While the flanges usually get welded or screwed, joints use a gasket between two flanges to build a seal.

Flange hole and bolting at lowest cost in Maharashtra

Flange hole and Bolting

Flange holes differ in number and diameter based on the pressure rating of the component. The bolt holes get distributed uniformly. In ASTM A182 F304 flanges, the number of holes is usually even, for example, 4, 8, 12, etc. You can find the specifications listed under ASME B16.5.

The sealing approach also decides the positioning of the holes. They span the sides of the line for vertical flanges where the surface is perpendicular, but the pipeline is horizontal. However, the holes get placed astride the centerline for horizontal flange faces with the bore vertical.

What is a Flat Face & Raised Face Class 150 Stainless Steel Slip on Flange?

Gandhi Metal India supplies different types of flanges depending on the face types. The most common ones include Raised Face and Flat Face flanges. A Raised Face Class 150 Stainless Steel Slip on Flange comprises a raised area around the pipe bore and gets manufactured with 304L or 316L grade. It is highly corrosion-resistant and ideal for operating under high and low pressures and temperatures. For example, a Class 150 flange can handle 270 PSIG at ambient conditions and around 75 PSIG at 800°F. These flanges align with ASTM A182 and ANSI B16.5 standards. Raised face flanges regularly get employed in oil and gas pipelines.

A Flat Face Flange uses non-metallic gaskets and is suited to less intensive applications, i.e., low temperature and pressure. The standard materials are Viton and EPDM (ethylene-propylene-diene monomer). It works well in piping, water treatment plants, and pump suctions. Flat Face Flanges prevent the bending moment created when the bolts experience torque.
