Technical requirements for pipe elbows
Date:2024-04-18
1, because most of the pipe fittings are used for welding, in order to improve the welding quality, the end of the car groove, leave a certain Angle, with a certain edge, this requirement is also strict, the thickness of the edge, the number of Angle and the deviation range are specified. The surface quality and mechanical properties are basically the same as the pipe. For easy welding, the steel of the fittings and the pipes to be connected is the same.
2. That is, all pipe fittings should be surface treated, the oxide sheet on the inside and outside surfaces should be sprayed off by shot peening, and then coated with anti-corrosion paint. This is for export needs, in addition, in order to facilitate transportation in China to prevent corrosion and oxidation, we should do this work.
3, The requirements for export packaging for small pipe fittings: you need to make a wooden box, about 1 cubic meter, the number of elbow in this box can not be more than one ton, the standard allows the a large set of small, but the total weight can not exceed 1 ton. For large piece, single package is required, like 24 ", single package is required. The other is packaging mark, mark is to indicate the size, steel number, lot number, manufacturer's trademark and so on.
