Banjo Elbow is a kind of connecting pipe commonly used in pipeline installation. It connects two pipes with the same or different nominal diameters to make the pipes turn at a certain angle. Elbow is widely used in pipeline construction and has irreplaceable functions. Below, what are the technical requirements of Banjo Elbow?
First of all, because most of the pipe fittings are connected by welding, in order to improve the welding quality, the ends are beveled, leaving a certain angle and with a certain edge. The requirements of this welding technology are relatively strict. The number and deviation range are specified. For the convenience of welding, generally, the steel grade of the pipe fitting and the pipe to be connected is the same.
Secondly, all pipe fittings need to be surface treated, iron oxide on the inner and outer surfaces needs to be removed by special treatment, and then painted with anti-corrosion paint, this is to facilitate transportation to prevent rust and oxidation, not only that, but the export also needs to do this work.
Finally, the elbow also has certain requirements for packaging. For small pipes such as elbows, a wooden box of about 1 cubic meter is required for export, and it is stipulated that the number of elbows in this box should not exceed about one ton, but Under the standard, sets are allowed, that is, large sets and small sets, but the total weight is generally not more than 1 ton. For large pieces of pipe fittings, a single package is required, and the other is the packaging mark. The mark should indicate the size, steel number, batch number, manufacturer's trademark, etc.
