Technical requirements for pumping tubes
The article Time : 2019-04-01
1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are all turned into bevels, the angle of stay, and the edges of the belts. This requirement is also stricter, how thick the edges are, how much the angle is and the range of deviation There are regulations. 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 steel of the pipe to be connected.we are provide concrete pump twin wall pipe
,you can know it.we can guarantee the quality of concrete pump twin wall pipe
2. All the pipe fittings must be surface treated, and the iron oxide skin on the inner and outer surfaces is sprayed off 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, is the requirements for packaging for small pipe fittings, such as exports, you need to do a wooden box, about 1 cubic meter, the number of elbows in this box is not more than one ton, the standard allows the suit, that is, a large set, However, the total weight can not exceed 1 ton. For large parts y, a single package, like a 24" single package. The other is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.
Pump tubes are widely distributed in industries with severe wear such as thermal power, steel, smelting, cement, machinery, coal, mining, chemical, port terminals.
