A234 WPB SR 45D Elbow, ASME B16.9, 3 Inch, SCH 40, Wrought, BW, Socket
Purpose
A pipe fitting commonly used in pipe installation to connect two pipes with the same or different nominal diameter to make a certain angle turn, nominal pressure of 1-1.6 Mpa.
Technical requirements for folding and editing of this paragraph
1. because most of the pipe fittings are used for welding, in order to improve the welding quality, the end part is groove, leaving a certain angle, with a certain edge, this requirement is also more strict, how thick the edge, how much angle and deviation range are stipulated. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the pipe fittings are the same as the steel type of the connected pipe.
2., all pipe fittings must be surface treated, the internal and external surface of the oxide sheet through shot peening treatment, and then coated with anticorrosive paint. This is for export needs, moreover, in the domestic is also to facilitate transportation to prevent corrosion and oxidation, to do this work.
3. is the requirement of packing for small pipe fittings, such as export, need to make wooden cases, about 1 cubic meter, the number of bends in this box should not exceed one ton, this standard allows suits, that is, large sets and small ones. But the total weight should not exceed 1 ton. For large y, a single package, such as 24" must be a single package. Also is the packing mark, the mark is to indicate the size, the steel number, the batch number, the factory trademark and so on.
