弯头操作规范指南

碳钢弯头技术要求

Technical requirements for carbon steel elbow

1、由于碳钢弯头大多数用于焊接,为了提高焊接质量,端部都车成坡口,留一定的角度,带-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样的。为了焊接方便,管件与被连接的管子的钢种是相同的。

  1. Because most carbon steel elbows are used for welding, in order to improve the welding quality, the ends are turned into grooves, leaving a certain angle, with fixed edges. This requirement is also relatively strict. There are regulations on the thickness of the edges, the angle and the deviation range. The surface quality and mechanical properties are basically the same as those of pipes. For the convenience of welding, the steel grade of the pipe fitting and the connected pipe is the same.

2、就是所有的碳钢弯头都要经过表面处理,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。

2. That is to say, all carbon steel elbows have to undergo surface treatment. The oxide scales on the inner and outer surfaces are sprayed off by shot peening, and then coated with anti-corrosion paint. This is to meet the needs of export. In addition, in China, it is also to facilitate transportation and prevent corrosion and oxidation.

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。

3. It is the requirement for packaging. For small pipe fittings, such as export, they need to be made into wooden cases, about 1 cubic meter. It is stipulated that the number of elbows in such cases should not exceed 1 ton. The standard allows suits, that is, large sets are small, but the total weight should not exceed 1 ton. For large items, you have to pack them individually. For example, for 24 "items, you have to pack them individually.
