ASTM A105 Forged Steel Flanges Manufacturers & Suppliers in India

ASTM A105 is a specification developed by the American Society for Testing and Materials (ASTM) for forged carbon steel piping components, including flanges, fittings, valves, and similar parts. It is one of the most commonly used specifications for carbon steel flanges in various industrial applications due to its wide availability, versatility, and compatibility with many types of piping systems.

Forged carbon steel flanges manufactured under the ASTM A105 specification are primarily used in high-pressure and high-temperature environments, such as in oil and gas, petrochemical, chemical, and power generation industries. These flanges are designed to withstand extreme conditions and provide reliable sealing connections in piping systems.

Material Composition: ASTM A105 specifies the chemical composition requirements for carbon steel forgings intended for use in pressure systems. The composition typically includes carbon, manganese, phosphorus, sulfur, silicon, and copper. The carbon content is limited to a maximum of 0.35%, making it suitable for welding applications.

Manufacturing Process: ASTM A105 Carbon Steel flanges are manufactured through the forging process, which involves shaping the raw material into the desired form by applying compressive forces. Forging enhances the mechanical properties of the material, such as strength, toughness, and resistance to impact and fatigue.

Pressure Ratings: ASTM A105 Carbon Steel flanges are available in various pressure ratings, ranging from 150 to 2500 pounds per square inch (psi). The pressure rating indicates the maximum pressure that the flange can withstand at a specific temperature without failure.

Dimensional Standards: Flanges manufactured under the ASTM A105 specification adhere to dimensional standards such as ASME B16.5 for pipe flanges and flanged fittings. These standards define the dimensions, tolerances, facing, and other relevant specifications for flanges to ensure interchangeability and compatibility with other components in the piping system.

Types and Facings: ASTM A105 Carbon Steel flanges are available in different types, including weld neck, slip-on, threaded, socket weld, and blind flanges, to suit various piping requirements. They may also feature different facing types, such as raised face (RF), flat face (FF), and ring type joint (RTJ), depending on the application and sealing requirements.

Corrosion Resistance: While carbon steel offers good strength and durability, it is susceptible to corrosion in certain environments, particularly those containing moisture, chemicals, or corrosive substances. Proper surface treatment, such as painting, coating, or galvanizing, can enhance the corrosion resistance of ASTM A105 flanges and extend their service life.

Quality Assurance: ASTM A105 specifies requirements for testing and inspection of forged carbon steel flanges to ensure compliance with the standard and quality consistency. Common tests include chemical analysis, mechanical testing (tensile, hardness), dimensional inspection, visual examination, and non-destructive testing (such as ultrasonic or radiographic examination).

ASTM A105 Forged Steel Flanges Manufacturing Process

Flange Forging

Compared to cast flanges, forged flanges typically contain less ASTM A105 Forged and are less likely to corrode. Forgings have superior mechanical qualities, a thicker structure, and a more streamlined shape.

Heat Treatment

The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds. The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds.

Forging Rolling

Roll forging is a forging technique that shapes a metal object by using opposing rolls. Although roll forging employs rolls to accomplish the desired material deformation, it is categorized as a metal forging procedure rather than a rolling procedure.

Rust Prevention

For steel flanges, conventional rust protection treatments include hot dip galvanizing, electro galvanizing (cold), varnish paint coating, black paint coating, black phosphating treatment, yellow (golden) paint coating, etc.
