ASTM A350 LF2 Class 1 and Class 2 Forged Fittings

ASTM A350 Lf2 Fittings and SA350 Grade.Lf2 Class 1 Forged Fittings Manufacturer

ASTM A350 LF2 Forged Fittings are killed and forged with low alloying elements. The fittings are of carbon steel and are used for high temperature and high pressure services. There are different standards to cover the dimensions such as the ASME 16.11 and others. Steel India Company is a leading manufacturer and supplier of the different fittings such as the A350 Lf2 Elbow and others in various dimensions and pressure classes. The elbow is one of the most used fittings that is used to change the pipe line direction either by 45 degrees angle or 90 degrees angle.

ASTM A350 LF2 Forged Fittings

SA350 Grade.Lf2 Class 1 Forged Fittings

The ASTM A350 Lf2 Fittings come in 1/8 inches to 36 inches nominal bore sizes. There are socket weld fittings and screwed fittings in addition to threaded A350 Lf2 Fittings. The different types are necessary for different types of fitting operations. The threaded fittings are used with threaded pipe ends. There are different pressure classes such as 2000LBs through 9000LBs. There are class 1 and 2 fittings which differ only in the chemical composition. The ASTM A350 Class 2 Forged Steel Fittings have higher mechanical properties than the class 1 fittings but the class 1 are the most used in applications. There are wrought austenitic carbon steel SA350 Gr Lf2 Forged Fittings that are used in applications like the petrochemical, petroleum, oil and gas and other fluid transmission pipe lines. There are elbows, unions, crosses, couplings, caps, bushing and other LF2 Carbon Steel Fittings that are used in the high temperature pressure applications. Please feel free to contact us for more information on the different types of fittings such as the SA350 Gr Lf2 Threaded Reducing Tee and other fittings along with the pricings.
