Since Liming is a hot forming elbow machine Supplier so there are some suggestions for elbows
1. Most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are all turned into bevels, leaving a certain angle with a certain edge. This requirement is also stricter, the thickness is too thick, the angle is how much and the deviation The scope has provisions. The surface quality and mechanical properties are basically the same as the tube. For the convenience of welding, the pipe is the same as the high quality hot forming elbow machine of the pipe to be connected.
2. All the pipe fittings must be surface treated, and the iron oxide skin on the inner and outer surfaces is sprayed by shot peening, and then coated with anti-corrosive paint. This is for export needs, and in addition, in order to facilitate transportation and prevent corrosion and oxidation in the country, we must do this work.
3. It is the requirements for packaging for small pipe fittings, such as exports, you need to do wooden boxes, about 1 cubic meter, the number of elbows in this box is not more than one ton, the standard allows the suit, that is, large sets, However, the total weight cannot generally exceed 1 ton. For large pieces y, a single package is required, such as 24", it must be a single package. The other is the package mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.
