  1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, with a certain angle and a certain edge. This requirement is also relatively strict, and there are provisions for how many sides are thick, how many angles and deviation range. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the steel grade of Stainless Steel Pipe Fitting Elbow and connected pipes is the same.

  2. All pipe fittings shall be subject to surface treatment, and the oxide scale on the internal and external surfaces shall be shot blasted off and then coated with anti-corrosion paint. This is for export. Moreover, in order to facilitate transportation and prevent corrosion and oxidation at home, we need to do this work.

  3. That is to say, for small pipe fittings, if they are to be exported, they need to be made into wooden boxes, about 1 cubic meter. It is stipulated that the number of elbows in such boxes should not exceed one ton. This standard allows suits, that is, large sets are small, but the total weight should not exceed one ton. For big Y, we need a single package, like 24 ″, we need a single package. In addition, it is the packaging mark. The mark is to indicate the size, steel grade, batch number, manufacturer's trademark, etc.
