Elbow In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three kinds of 45° and 90°180° which are more commonly used. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. Do you know what its technical requirements are?

1、由于管件大部分用于焊接,为了提高焊接质量,管件端部均要开坡口,留有一定的角度,一定的边,这个要求也比较严格,边厚多少,角度多少,偏差范围都有规定。表面质量和力学性能与管材基本相同。为了焊接方便,管件和被连接的管材的钢级要相同。
2、就是所有管件都要进行表面处理,用喷丸的方法把内外表面的氧化铁皮喷掉,然后涂上防腐漆。这个是为了出口的需要。而且也是为了国内运输方便,防止腐蚀和氧化。这个工作是必须做的。
3.就是对包装的要求。对于小件的管件,比如出口的,是需要做木箱的,大概1立方米左右,这个箱子里的弯头数量不能超过一吨。标准允许成套,也就是大套和小套。但是总重量一般不能超过1吨。对于大件,需要单独包装,比如24”的必须单独包装。另外就是包装标志,必须注明尺寸,钢号,批号,厂家商标等。
