Carbon Steel F70 Flanges are high-strength carbon steel components for demanding applications requiring corrosion resistance, high pressure, and increased temperatures. The ASTM A694 specification, which establishes criteria for carbon and alloy steel forgings for pipe components such as flanges, fittings, valves, and other pressure-containing elements, is used to manufacture F70. Carbon Steel F70 Flanges are well-known for their outstanding mechanical features, which include high tensile strength, yield strength, and hardness. They are widely used in sectors such as oil and gas, petrochemicals, and power generation, where dependability, durability, and performance are critical.

There are several types of carbon steel F70 flanges, two of which are explained, and the rest are mentioned in the table below. Orifice Flanges: Orifice flanges are specifically designed to measure the flow rate of fluids in a pipeline using orifice meters. They feature pressure tappings machined into their surface to accommodate the orifice metering device. Spacer Flanges: Spacer flanges, also known as spectacle blinds or line blinds, are used to temporarily blind or isolate pipeline sections. They consist of a pair of metal discs connected by a central steel bar or spacer. Spacer flanges are typically installed between two flanges, and by rotating the spacer, the pipeline can be either opened or closed, allowing for easy maintenance or repairs while maintaining pipeline integrity.

Carbon Steel: F70 flanges are primarily made from high-strength carbon steel, offering excellent mechanical properties and corrosion resistance. Alloy Steel: Some flanges may incorporate alloy steel to enhance properties such as hardness, toughness, and resistance to corrosion and high temperatures. Stainless Steel: Certain variants of F70 flanges may utilise stainless steel for superior corrosion resistance, particularly in aggressive chemical or high-temperature environments. Duplex Steel: Duplex steel may also be employed for F70 flanges, pr
