1, seamless steel pipe grinding and polishing: the end of the laser cutting, should be applied to grind the plastic layer of the branch pipe grinding and polishing solution, the purpose is to prevent the plastic layer in the flange welding melt or even ignite the pipeline destruction. Apply the grinder to carry out grinding and polishing of the plastic layer of the branch pipe.

2, seamless steel pipe plating solution: grinding and polishing end, the application of co2, C2H2 in the pipeline outside the pipe to carry out heating, heating to the internal plastic layer part of the molten condition, followed by technical workers will be prepared with electrostatic powder on the pipe evenly wiped, should pay attention to be wiped in a timely manner, the flange plating should be wiped on top of the waterproof line. This whole process should be strictly controlled heating temperature, such as temperature is too high, in the process of plating will appear bubble caused, seamless steel pipe how much money, such as temperature is too low, in the whole process of plating plastics electrostatic powder melting is not complete, how much money a ton of seamless steel pipe, the above conditions in the pipeline after delivery and use will cause the plastic layer down the condition of the zui final seamless steel pipe part of the pipeline was destroyed by erosion.

3, seamless steel pipe laser cutting: according to the specific length of the pipe required, the pipe should be applied to the metal material saw, toothless saw laser cutting. In the whole process of laser cutting, the application of water welding must have raw material maintenance. Laser cutting, fire safety and high temperature resistant raw materials should be selected as a partition, in the laser cutting to capture the fire and hot iron beans, in order to maintain the initial plastic layer of raw materials.

4, seamless steel pipe line connection: fill plastic end, hot dip galvanized groove pipe manufacturer, will pipe and pipe connection installation, in the connection of the whole process of flange in the middle of the rubber plate, tighten the foot bolt when tightened to the sealing situation.
