Product Description
ASTM A182 F316L Socket Weld Elbow Class 3000 Forged Fitting
SMLSCO Forged Fitting Manufacturing Process
The excellent strength of SMLSCO pipe fittings comes from rigorous
forging processes. We use standard round bars as raw materials,
which are cut, heated, and then forged as a whole on a forging
press. This process greatly refines the internal grain structure of
the metal and eliminates potential metallurgical defects.
Subsequently, the forged blank undergoes heat treatment and
precision CNC machining to form precise socket dimensions and
groove angles, ensuring full compliance with the dimensional
tolerance requirements of ASME B16.11.

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.
