Pipe Fittings technical requirements

PIPE Fittings technical requirements are the following:

 

Geometry including diameter, diameter, wall thickness. Also required to control the radius of curvature. Such as length of the radius of 1.5d, then the radius of curvature must be within the required tolerance range. Most of these fittings for welding, in order to improve the quality of welding, the end portion is a bevel drive, leaving a certain angle with a certain side of this one relatively strict requirements, how thick side, a little deviation angle have provisions geometry on a lot more than the pipe items.

Surface quality and mechanical properties of the same base and the tube. In order to facilitate welding, and the connection of the steel tube is the same. The fourth is that all the pipe pieces to go through surface treatment, the inner and outer surfaces of the oxide scale spraying out through shot peening, and then coated with anti-corrosion paint. Both for export needs. Moreover, in order to facilitate transport in the country is to prevent corrosion oxidation, have to do this work. Fifth, is the packaging requirements for small pipe fittings, such as exports, we need to do wooden box, about one cubic meter, the provisions in this case can not exceed the number of elbows about a ton, the standard allows suit, namely large set small, but the total weight generally not more than 1 ton.

 

For large should a single package, like the 24 "must be individually packaged addition is the packaging tags, which is to indicate the size, steel number, batch number, manufacturer trademarks of play on the tube on the stamp, along with the packing list and warranty book and other documents.
