HQ Pipeline produces kinds of fittings like Forged Steel FittingsSteel Flanges, Butt Weld  Fittings, Nipples and Coupling, UL/FM Ductile Iron Grooved Fittings and Grooved Couplings. So What kinds of technology do fittings need?


Firstly, because most pipes used for welding, in order to improve the quality, groove cut will effectively solve the problems, leaving a certain angle, with some edges. This requirements are quite strict,and how thick the edge is, what size the angle is and deviations are provided. Surface quality and mechanical properties of the pipes are same. For the convenience of welding, pipe fittings and connected steel pipes’ s material are same too.


Secondly, all the outside elbows need surface treatment, and the iron oxide scales of Interior and exterior surfaces need to be blast  by sprayed, then we need to coat them with anti-corrosion paint. This is for the export, moreover, even in the country. It can prevent rust oxidation in transportion.

Thirdly, it is the packaging requirements for small fittings, such as export, you need wooden boxes, about 1 cubic meter. It requires the number of elbows in boxes cannot be more than about one ton, which allows suits, but generally it should not exceed the total weight 1 ton. For the bigger one ,it needs a single package, like 24", it must be a single package.Else, it’ s the  packaging tags, tags need to  indicate size, number, manufacturer and so on.
