ASTM A182 F316L Socket Weld Elbow Class 3000 Forged Fitting

What are the Types of Forged Elbow?
Forged elbows are key fittings used to change the direction of fluid in high-pressure piping systems. They are mainly classified based on angle and bending radius. The most common angles are 90 ° (for right angle turns) and 45 ° (for gentle turns). In addition, according to different bending radii, it is also divided into long radius (LR), which has lower fluid resistance; And short radius (SR), suitable for situations with compact installation space. SMLSCO can provide various types of forged elbows according to customers' specific pipeline layout requirements.

Forged Fitting Pressure Ratings:
The pressure rating of forged pipe fittings follows standards such as ASME B16.11, which is different from the Class system of flanges. The pressure rating of socket weld fittings is usually divided into three levels: Class 3000, 6000, and 9000. Class 3000 is designed specifically for high-pressure conditions and is suitable for systems with thick walled pipelines, capable of withstanding harsh internal pressures. It is widely used in industries such as petroleum, chemical, and power, and is the foundation for ensuring the safe and leak free operation of high-pressure small-diameter pipeline systems.
