45 Degree Stainless Steel Butt Weld Fittings Sch 10S Sch20 Elbow

ASTM A403 45 Degree BW Elbow Stainless Steel Butt Welding Fitting

According to fluid direction of the pipelines, elbow can be divided into different degrees, such as 45 degree, 90 degree,180 degree, which are most common degrees. Also there has 60 degree and 120 degree, for some special pipelines.

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.

45 degree elbow of long radius

The 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 and rubber fixtures. It is widely used in chemical, food, water supply facilities, electronic industry, chemical pipelines, horticulture, agriculture production, solar equipment pipelines, air conditioning pipeline and other fields.

Class WP Fitting Categorizations

Class WP fittings are subdivided into three subclasses: Classes WP-S, WP-W. and WPWX. They are manufactured to the requirements of ANSI BI6.9, BI6.11, BI6.28, or MSS Standard Practice SP-79, and they have pressure ratings compatible with 9.2.

Class WP-S fittings are those manufactured from seamless product by a seamless method of manufacture (marked with class symbol WP-S);

Class WP-W fittings contain welds where the fitting fabrication or construction welds have been radiographed (marked with class symbol WP-W);

Class WP-WX fittings are those which contain welds where alI welds have been radiographed (marked with class symbol WP-WX).

Product Information

Materials Chemical Compositions

ASTM A403 Stainless Steel Pipe Fittings refers to the material of forged and rolled austenitic stainless fittings for pressure pipes. Common grades are WP304/L, WP316/L. They can be used into many fields as engineering industry, energy conversion plants etc

Note:

Where a ellipsis(﹍)appears in the table, there is no requirement and the element need to be analyzed for or reported

The method of analysis for nitrogen shall be a matter of agreement between the purchaser and manufacturer

Columbium 0.10-0.30%; Vanadium 0.10-0.30%.

For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.04% is necessary in grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500in.(23.7mm) in outside diameter and light wall tubes as those less than 0.049in.(1.24mm) in average wall thickness
