As we know, according to fuid direction of the pipelines, elbow can be divided into diferent degrees, such as 45 degree, 90 degree,180degree, which are most common degrees.  Also there has 60 degree and 120 degree, for some special pipelines.

45 degree elbow

45 degree elbow of long radiusThe pipe elbow is mounted between two pipes so that the fluid direction can be changed to 45 degrees. Compared to 90 degree elbow,45 degree elbow produces less friction, and with the lower pressure.

45 degree elbow of short radius

SR Elbow in 45 degree is usually attached to copper, plastic, steel, cast iron and lead, and can also be connected to stainless andrubber fixtures. lt is widely used in chemical, food, water supply facilties, electronic industry, chemical pipelines, horticulture, agricultureproduction, solar equipment pipelines, air conditioning pipeline and other fields.

90 degree steel pipe elbow

Long radius 90 degree elbow

LR 90 degree steel pipe elbow are installed between diferent lengths pipe or tubing. lt helps to change direction at 90 degree, and iscommonly used to connect hoses to pumps, deck drains and valve.

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

180 Degree steel Elbow180 Degree steel elbow helps change direction at 180 degrees, since it usually results in low pressure. lts application is limited tominimal deposition and low turbulence system.
