Groove Tube Groove Tube precautions when mounting bolts when connecting clamps, silver plastic-lined pipe trench, to apply a layer of lubricant inside the clamp, in part to get stuck rubber seals, there is to The clamp convex border checkpoint inside the trench, then hand-tighten the bolts lined groove tube, you can use a rubber hammer percussion bolt clamp tight convex line, Fujian lined pipe trench, Forbidden to use a hammer or other heavy percussion wrench to avoid damage to the surface of the tube, lined pipe trench sales, reduce safety performance. When tightening the bolts first and tighten the bolt cap, pay attention to the rubber seal when the cap is screwed bolt clamps are inside, tight seal preventing leakage affect the sealing effect at the same time affect the overall appearance. Lined pipe trench performance:? High corrosion resistance plastic-lined pipe trench density is high, with good corrosion resistance. To avoid secondary contamination of drinking water, effectively extending tube life? Good mechanical strength plastic-lined pipe trench has a hot dip galvanized steel equal (or even better) than the mechanical strength, impact, pressure and intensity of the look, with more strong endurance lined trench tube manufacturers, Fujian lined pipe trench, Chuanhai machinery supplied by Weifang Chuanhai Machinery Co.
