Eblow

Elbow

Elbow in the pipeline system, the elbow pipe fitting, to change the pipeline direction. According to the point of view, there are 45 DEG and 90 DEG to 180 DEG three most commonly used. According to the need of the project,  also includes a 60 degree angle. Other non normal elbow elbow materials of cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. Tube connection: direct welding (the most common way) hot melt connection, flange connection, welding connection, threaded and socket connections.

Technical requirements for eblow

1, because most fittings used for welding, in order to improve the quality of welding, the end of all vehicles into a groove, keep the certain angle, with a certain edge, this requirement is quite strict, more thick, much angle and deviation range are defined. The surface quality and mechanical properties of the pipe is basic and the same. For convenient welding, steel pipe and the connecting pipe is the same.

2, all fittings must be after surface treatment, the scale of the inner and outer surface of spray off by shot peening, then coated with anticorrosive paint. This is to export to, moreover, is for the convenience of transportation in China to prevent rust oxidation, to do this work.

3, is the packaging requirements for small fittings, such as export, they need to do the wooden case, about 1 cubic meters, the specified number of the elbow in box about no more than one ton, the standard Allow the suit is small, but the total weight is generally not more than 1 tons. For large y to a single package, like 24 “must be a single package. The other is labeled packaging, labeling is to indicate the size, number, batch number, trademarks and other manufacturers.
