45 ° elbow is the most commonly used elbow in pipeline installation, and it is a fitting that changes the direction of the pipeline in the pipeline system. The curvature radius of all elbows is R ≤ 3D, and the most commonly used are long radius elbows with R=1.5D and short radius elbows with R=1D. The commonly used angles are 90 °, 45 °, and 180 °. Sometimes, there is also a small amount of use of reducing elbows (i.e. connecting to reducing pipes while changing the direction of the pipes). Our company can also customize other non-standard elbows according to engineering needs. Elbows can be classified into three types based on material: stainless steel, carbon steel, and alloy steel.

Butt welded pipe fittings are fittings that are connected to pipes by welding, especially suitable for long pipelines, but not suitable for pipelines that require frequent disassembly. In pipeline systems, welded pipe fittings are pressure pipeline components used to change the direction or diameter of pipelines, branch pipelines, and achieve special connection functions in production equipment such as petrochemical and power plants. It is an important component of pressure pipeline equipment. Due to changes in the flow direction and flow area of the medium at its installation location, its internal and external stress situations are relatively complex. Therefore, the quality level of the pipe fittings directly affects the safe and stable operation of the entire pipeline system. They have multiple product types to choose from, such as 90 degree elbows, 45 degree elbows, tees, crosses, pipe caps, concentric reducers, eccentric reducers, and flanged short joints.
Butt welded pipe fittings are a type of high-quality pipe fittings manufactured from welded pipes, which are widely used in the construction industry. They mainly include butt welded pipe fittings made of stainless steel, carbon steel, low alloy steel, and alloy steel. Compared with ordinary welded pipe fittings, welded pipe fittings have more durable characteristics and are less prone to deterioration due to external environmental conditions. Welded pipe fittings play an indispensable role in construction engineering and are a widely used type of welded pipe fittings.
