304 stainless steel elbow pipe fittings

タイトルまたは説明

1. Because most of the pipe fittings are used for welding, in order to improve the welding quality, the end of the car is beveled, leaving a certain angle, with a certain edge, this requirement is also relatively strict, how thick the edge, how much angle and deviation range are stipulated. 
The surface quality and mechanical properties are basically the same as those of the pipe. 
For the convenience of welding, the pipe fitting is the same kind of steel as the connected pipe. 
2. That is, all pipe fittings should be treated by surface treatment, and the iron oxide scale on the inner and outer surface should be sprayed off by shot peening and then coated with anticorrosive paint. 
This is for export needs, in addition, in order to facilitate transport to prevent corrosion and oxidation, we have to do this work. 
3. That is, the requirements for packaging. For small pipe fittings, such as export, it is necessary to make wooden cases, about 1 cubic meters. It is stipulated that the number of elbows in this kind of box cannot exceed one ton. This standard allows sets, that is, large and small sets. 
However, the total weight shall not exceed 1 ton in general. 
For large pieces y need a single package, such as 24 "must be a single package." 
In addition, the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.
