Carbon Steel Pipeline Fittings For Pressure Usage Carbon Steel Pipe Elbow
Fittings made from block forgings may only be supplied subject to agreement between the manufacturer and purchaser. Such fittings need not meet the requirements of section 7. For applications where fatigue loading is a concern, required minimum dimensions shall be furnished by the purchaser. Fittings may be made to special dimensions, sizes, shapes, and tolerances by agreement between the manufacturer and the purchaser.The ways of connecting with the pipe are: direct welding (the more common way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection, etc.
According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow and so on.Other names: 90 degree bend, right Angle bend, etcCarbon steel elbow can be divided into long radius elbow and short radius elbow according to its radius of curvature.Long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, i.e., R= 1.5d.Product furnished to this specifification shall conform to the requirements of Specifification A960/A960M, including any supplementary requirements that are indicated in the purchase order. Failure to comply with the requirements of Specifification A960/A960M constitutes non-conformance with this specififi-cation. In case of a conflflict between the requirements of this specifification and Specifification A960/A960M, this specifification shall prevail.Wrought fittings covered by this Standard shall be in accordance with ASTM A234, ASTM A403, ASTM A420, ASTM A815, ASTM B361, ASTM B363, ASTM B366, or the corresponding specification listed in ASME BPVC, Section II. The term “wrought” denotes fittings made of pipe, tubing, plate, or forgings.
This Standard states values in both SI (Metric) and U.S.Customary units. These systems of units are to be regarded separately as standard. Within the text and tables, the U.S. Customary units are shown in parentheses. The values statedin each systemare not exact equivalents;therefore, it is required that each system of units be used independently of the other. Combining values from the two systems constitutes nonconformance with the Standard. ipe fitting, as the name suggests, is the part that connects bai sons into a pipe, which plays the roles of connecting, controlling the direction, diverting, supporting the pipe and sealing in the pipe.This article mainly introduces what the pipe fittings are and what the standards of pipe fittings are.
According to the pipe fitting, the pipe fittings can be classified into six categories: pipe fittings connected with pipes, including flanged pipe fittings, live pipe connectors, clamped sleeve fittings, pipe band fittings, etc.Pipe fittings used to change the direction of the pipe, including elbow pipe fittings and elbow pipe fittings;Pipe fittings used to change the pipe diameter, including reducing pipe fittings (i.e., reducing pipe fittings), reducing elbow pipe fittings, branch pipe bench pipe fittings, reinforcement pipe fittings;Fittings for adding branches of pipelines, including tee fittings and stone fittings;Pipe fittings used for sealing pipes, including gasket pipe fittings, head pipe fittings, flanged blind plate pipe fittings, pipe plugging fittings and welding plug pipe fittings;Pipe fittings used for fixing pipelines, including clamping ring pipe fittings, decoupling pipe fittings, lifting ring pipe fittings, bracket pipe fittings and bracket pipe fittings, etc.
