1. Large Pipe Diameter 【 Spring 】
Tips of large pipe diameter construction
1, due to the large diameter of the construction material width is too large, the protection measures of the wellhead are particularly important. It needs to avoid the material being scratched when cutting.
2. When cutting materials, selecting professional blanking auxiliary equipment can improve the construction efficiency to a certain extent.
3. Select the packer corresponding to the diameter of the pipe, and bind the materials at both ends tightly to increase the guarantee that the repair material can reach the standard pressure during the pressure.

2, high temperature environment construction part 【 Summer 】
Tips of Summer high temperature construction
1, In the summer construction, pay attention to the impact of high temperature on the material. Especially under high temperature conditions, the material cannot be stored outdoors for a long time, and if the outer film is damaged, it may lead to early solidification of the localization of materials.
2, In the case of high temperature construction, for the on-site construction personnel is also a huge challenge. It is recommended that the construction unit as far as possible to choose the night construction.

3, Super thick pipe diameter construction [Autumn]
Tips of super thick pipe diameter construction
1, The material is too thick to cause the material is too heavy. The traction equipment needs to match the weight of the material.During the traction process, be sure to consider a comprehensive plan to avoid the rope of the traction material halfway interrupted.
2, In the curing process of super thick materials, according to the different equipment, UV curing equipment parameters are different. In the curing of the material that more than conventional thickness , the prerequisite is the centered light source, the curing speed needs to be calculated (the length of the lamp stand/the top of the material tail fully curing time)
Assumption: With the material thickness of 18mm as the premise, the lamp stand is 4.3 meters, and the curing time of the tail tip is 45min
The result is :4.3/45=0.095m/min
Hose curing lamp stand travel speed:
When the pressure in the hose reaches the value, turn on the stopwatch after the UV lamp, and calculate the time after the tail material is completely cured.
Calculation method of travelling speed of light frame:
Light frame length ÷ full curing time of the tail UV lamp after turning on the light = the fastest curing speed of the lamp frame
The above formula is for the conventional thickness pipe diameter, and the curing of ultra-thick pipe diameter needs to be analyzed in combination with the actual situation on site

4, Winter material insulation construction 【 Winter 】
Tips of cold area construction
1, Before construction, ensuring that the material is stored in a suitable temperature environment, and ensuring that the temperature of the hose material in the box is at least 5 ° C before construction, preferably more than 10 ° C.
2, Before construction, ensuring that the site pre-processing work is fully prepared before the removal of the packaging box, to avoid early unpacking caused by the hose material cooling and hardening.
3, sub-zero curing needs to use the wind of the equipment to warm the material before it is carried out.
