AISI 4130 alloy flange is a low alloy steel flange with excellent strength, toughness and high tensile properties. The material is widely used in the oil and gas industry in the manufacture of drilling equipment and components, as well as in piping and pressure vessel systems.
AISI 4130 Welding Neck Flange is made of high-quality AISI 4130 steel, which has undergone precision machining and heat treatment to ensure it has good mechanical properties and corrosion resistance. This kind of flange has high strength and good plasticity, and can withstand various complex working environments, such as high temperature, high pressure, corrosive media, etc.
AISI 4130 Lap Joint Flange is available in a wide range of sizes from ½ inch to 60 inches to meet a variety of piping system joining needs. Its excellent mechanical properties and corrosion resistance make it ideal for use in oil, gas, chemicals and other industrial sectors.
AISI 4130 flange can also be used in construction, shipbuilding, power, transportation and other industrial fields. It can be welded or threaded with other materials (such as cast iron, stainless steel, etc.) to achieve reliable pipe connections.

4130 Alloy Steel Flanges
What is AISI 4130 Flanges ?
G41300 Pipe Flanges belong to the ASTM A182 specification and are used in high pressure high temperature applications such as oil and has, heat exchanger and in power generation units. There are different types but the AISI 4130 blind flanges are special in that they are used to close a pipeline than continuing it. It is useful in test systems and cleaning the pipelines.
