弯头技术要求Technical requirements of elbow
1、由于管件大多数用于焊接，为了提高焊接质量，端部都车成坡口，留一定的角度，带一定的边，这一项要求也比较严，边多厚，角度为多少和偏差范围都有规定。表面质量和机械性能基本和管子是一样的。为了焊接方便，管件与被连接的管子的钢种是相同的。
2、就是所有的管件都要经过表面处理，把内外表面的氧化铁皮通过喷丸处理喷掉，再涂上防腐漆。这是为了出口需要，再者，在国内也是为了方便运输防止锈蚀氧化，都要做这方面的工作。
3、就是对包装的要求对于小管件，如出口，就需要做木箱，大约1立方米，规定这种箱子中的弯头数量大约不能超过一吨，该标准允许套装，即大套小，但总重量一般不可超过1吨。对于大件y就要单个包装，像24″的就必须单个包装。另外就是包装标记，标记是要注明尺寸、钢号、批号、厂家商标等。
1, as most of the pipe fittings are used for welding, in order to improve the welding quality, the end is all turning into a slope, leaving a certain angle and with a certain edge. This requirement is also strict, the edge is thick, the angle is as much as the range and the range of the deviation are all stipulated. The surface quality and mechanical properties are basically the same as those of pipes. For the convenience of welding, the fittings of the pipe and the connected pipe are the same.
2, that is, all fittings must be treated by surface treatment. The oxide scales inside and outside are sprayed out by shot peening, and then coated with anticorrosive paint. This is for export needs. In addition, it is also for domestic transportation to prevent rust and oxidation.
3, the requirements for the packaging for small pipes, such as the export, the need to do wooden cases, about 1 cubic meters, the number of bends in this box can not be more than one ton, the standard allows suit, that is, large sets, but the total weight is generally not more than 1 tons. For large y, a single package is required, like 24 ', which must be packed individually. Another is the packaging mark, marking is the size, the steel number, the batch number, the manufacturer trademark and so on.
