4IN SCH40 Stainless Steel 90 Degree Elbow

Steel pipe elbow is a key parts in a piping system for to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe turn to a certain direction of 45 degree or 90 degree.

This is the product which has degrees such as 45 degree, 90 degree and many more. The design of this is very simple like curve shape and both the ends can be buttweld or cast. Long Radius Elbow Pipe Fittings has some amazing functions like corrosion resistance, it lasts for longer period of time. As we discussed that this elbow has various degrees, such as 45- and 90-degree long radius elbow. This product specifications are divided into many forms such as dimension, thickness, schedule, size and type. Therefore, we would recommend you to manufacture long radius reducing elbow from our company and we will deliver the best to you.

What is Elbow Radius
The elbow radius mean curvature radius. If the radius is the same as pipe diameter, it called short radius elbow, also called SR elbow, normally for low pressure and low speed pipelines.
If the radius is larger than pipe diameter, R ≥ 1.5 Diameter, then we call it a long radius elbow (LR Elbow), applied for high pressure and high flow rate pipelines.

90 Degree Steel Pipe Elbow
90 degree steel pipe elbow functioned to change fluid direction by 90 degree, so also named as vertical elbow. It is the common degree in all the pipeline systems and used most in all different degree of elbows. (As it is convenient to suit to steel construction and structural.)

Long radius 90 degree elbow
LR 90 degree steel pipe elbow are installed between different lengths pipe or tubing. It helps to change direction at 90 degree, and is commonly used to connect hoses to pumps, deck drains and valve.

Short radius 90 degree elbow
SR 90 degree elbow is the same as the pipe elbow mentioned above, but the diameter is shorter. Therefore, this kind of steel elbow is often used when space is not enough.

Stainless Steel Pipe Elbow

Stainless steel pipe elbow has higher strength and higher corrosion-resistances than carbon steel elbow. For general surface treatment, stainless steel elbow is used in high corrosion environment, such as chemical plants, offshore and gas pipelines. Surface treatment in 2B or mirror, these are used in food industries and sanitary purposes.

Stainless steel 90 degree elbow

Stainless steel 90 degree elbow is a most common use of pipe elbow for stainless pipelines. Other than this is stainless steel 45 degree elbow, both of them in large requirements for butt weld, socket weld, and threaded connections.

Butt Weld Elbow
Butt weld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to directly weld the elbow and steel pipe. Butt welded elbows are mainly used for elbow with higher pressure and temperature than other connection types (socket welded elbow or threaded pipe elbow).
