DFPB双金属重防护护桥管

DFPB双金属重防护护桥管是把普通钢管经过工艺处理,横向安装时,两固**之间的间距为,涂层复合管公称外径不小 于76mm时,应不大于1100mm。涂塑钢涂层在端口完好,应采用削刀削成倾内倒角。在钢管内、外层表面经涂敷一种特制的聚乙烯材料而制得的其表面具有抗静电、阻燃性能的钢塑复合管。先在钢管两端焊接法兰,法兰应焊接牢固,再经聚乙烯涂敷。沟槽应采用**滚槽机压槽,注意沟槽深度应符合相关标准(CJ/T156).管道切割应采用金属锯,大口径管宜采用锯床,使用盘踞切割时,其转速不得大于800r/min。安装时,在涂层复合管的两法兰间加装密封垫,用螺栓压紧即可。
DFPB bimetal heavy protection bridge pipe is a common steel pipe after process treatment, transverse installation, the distance between the two fixed points, coating composite pipe nominal diameter is not less than 76mm, should not be more than 1100 mm. The coated steel coating is in good condition and should be cut into chamfering by cutting knife. Steel-plastic composite pipes with antistatic and flame retardant properties were prepared by coating a special polyethylene material on the inner and outer surfaces of the pipes. Flange is welded at both ends of the steel pipe. The flange should be soldered firmly and then coated with polyethylene. The groove shall be pressed by a special grooving machine, and the depth of the groove shall conform to the relevant standards (CJ/T156). The metal saw shall be used for pipe cutting, the saw machine shall be used for large diameter pipe cutting, and the rotational speed shall not exceed 800r/min when the plate cutting is used. When installing, insert the gasket between the two orchids of the coating composite pipe and press it with bolts.
