Compared with the commonly used metal well pipes and reinforced concrete well pipes, the plastic shaft wall pipe has the following performance characteristics:
①The pipe is light. The dead weight of plastic well pipes can be reduced by 76%, 85% and 82% respectively than steel well pipes, zhuan cast iron well pipes and reinforced concrete well pipes.
②The running time is short, which is conducive to well completion. The length of each section of plastic well pipe is generally 6m, which can reduce the number of joints by 1/3 compared with other pipe materials. Moreover, the connection method of plastic well pipe adopts socket and screw riveting method, which can save money compared with other well pipes. About 1/2 of the time. After actual measurement, the construction of a 300m deep well, plastic well pipes can save 39%, 59% and 63% of the running time compared with cast iron well pipes, steel well pipes and reinforced concrete well pipes, respectively. The shortening of the running time will greatly improve the completion rate and quality of the deep well.
③Anti-corrosion, prolong the service life of the motorized well, and completely avoid the secondary pollution of the pipe to the well water.
④ The tubing is cheap, which can reduce the cost of a single well by 22% and 31% respectively compared with steel well pipes and cast iron well pipes.
