Comparison of existing technical schemes for coal mine pipelines  | ||||
numerical order  | existing technology  | contrastive analysis  | ||
1  | Polyethylene pipes for underground coal mines  | Applicable caliber range is large, but the pressure is relatively
small, generally the highest 1.6Mpa, the price of the same specification model is lower.  | ||
2  | Steel mesh skeleton polyethylene pipe used in underground coal mine  | Applicable caliber range is large, but the applicable pressure is
small, DN200 up to 2.5MPa. The same specification model is the
highest price.  | ||
3  | Fiber-reinforced polyethylene liquid pipes for coal mines  | Applicable caliber range is large, the pressure is high, up to
4Mpa, the use of non-metal or metal withholding joint, according to
the working conditions, the pipeline can be fixed length, can coil,
construction is convenient and fast. Best value for money  | ||
