管件

法兰的制造过程主要分为锻造，铸造，切割和轧制。　　The casting and forging flanges have advantages that the blanks of them have accurate shape, size and low costs and only need simple process. But forging flanges have manufacturing defects such as blowholes, cracks, etc and have not very smooth internal organization streamline. The obvious advantages of forging flanges are that they can be forged in various shapes and they have low costs. 　　Forging flanges generally have lower carbon content than the casting flanges and are not easy to rust. They have smooth streamline, uniform internal […]

钢管弯头是管道管道系统中的重要零件，用于改变流体方向。它根据身体材料的不同类型范围有不锈钢弯头，碳钢弯头和合金钢;根据流体方向，有45度，90度弯头和180度;根据弯头长度和半径，有短的半径弯头（SR弯头）和长半径弯头（LR弯头）;根据连接类型，有对接焊缝弯头，插座焊缝和螺纹钢管弯头。90级钢管弯头90度钢管弯头是[...]
