Select Zebang Technology for Gas Drain Rubber Hoses in Coal Mine
It is mainly used for flexible connection between underground gas negative pressure drainage pipelines and devices in coal mines. It has good bending performance and solves the air-tightness problem of coal gas negative pressure drainage hard pipes and connections between devices. It has installation and use Convenient, flame retardant, antistatic and other advantages. The gas drainage hose uses polyvinyl chloride as the main raw material, and the elastic spiral steel wire is implanted in the pipe wall to optimize the product. It is especially suitable for underground gas drainage systems and drilling and sealing of coal mines. Used in areas such as external connections. zmjt047 China Coal
The spiral steel wire is used as the skeleton support, which has a certain strength and hardness. The hose has good bending performance and is extremely convenient to install and use. It is matched with the outer diameter of a hard PVC pipe used in the mine and can be directly inserted after use. It can be tight; it has the dual performance of flame retardant and antistatic, and the dual resistance performance is durable, suitable for the connection between underground gas drainage hard pipes; corrosion resistance and no scaling.

Mine gas drainage hose is an environmentally friendly plastic pipe. It uses polyethylene as the main raw material and adds appropriate amounts of flame retardant and antistatic auxiliary agents. It is mainly used for gas drainage, ventilation, drainage and shotcrete in underground coal mines. It can produce products with different specifications and different performances according to the actual needs of the underground, and it also has matching straight-throughs, tees, elbows, connections, etc.
1. Large bendability: This pipe is easy to bend around obstacles to facilitate going down the well, reducing the amount of pipe fittings and reducing labor intensity.
2. High corrosion resistance: The production environment in coal mines is harsh, and the liquid is highly corrosive. The pipe can withstand the corrosion of various chemical media.
3. Strong flexibility and impact resistance: good toughness, high impact strength, heavy objects directly pressing through the pipeline, better pressure bearing capacity, will not cause pipeline rupture.
4. Good deformation resistance: Under the same conditions, the tensile strength and elongation are higher than those of steel pipes. When the foundation is settled, it can withstand a certain degree of deformation and remain unbroken, but the steel pipes are prone to fracture and collision. Sparks can cause unsafe risks.
5. Stable flame retardant and antistatic performance: special coupling agent is used for surface activation of antistatic electrostatic flame retardant additives to form a "molecular bridge" with the resin matrix and fuse into a whole with a small amount of addition to achieve Very good dual antibody effect.
6. Small circulation resistance: The tube wall has a high degree of smoothness and a small coefficient of friction. At the same flow rate, the pipeline flow is stronger than that of steel pipes.
The product has been exported to the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other countries, and has won unanimous praise from customers.
