D7焊接横担 吊架D7焊接横担 恒轩管道D7焊接横担

焊接横担D7焊接横担D7A焊接横担，由槽钢×2、垫板×2、支座×1组合而成，其与D6型管夹横担的区别在于：去除了支座上面焊接的管夹。焊接横担与管道的固定方式为焊接，即将管道与支座的接触面以焊接工艺进行固定。焊接横担两端底部的F3垫板开孔用于穿过螺纹吊杆，螺纹吊杆与槽钢之间以螺栓螺母进行固定，组成管道悬吊系统。表面处理方式一般是喷防锈漆，制作材质根据不同的需求而采用不同材质，设计手册上按照不超过300°C的温度环境，采用Q235碳钢材质。订货时表示方法为：焊接横担D7.273S（使用管径Dw=273，S为材料代号）。该产品是西北电力设计院1983年颁布的汽水管道支吊架设计手册中的管部吊架类产品，是管道常见的管道悬吊系统组件之一。
