Introduction Of Coal Mine Underground Flexible Drainage Gas Rubber Hos Mining Hose

The gas drainage hose is mainly used for the flexible connection between the underground gas drainage pipeline and the device in the underground coal mine, and has good bending performance, and solves the airtightness problem of the connection between the coal mine gas negative pressure drainage pipe and the device. It has the advantages of easy installation, convenient use, flame retardant and antistatic. The gas drainage hose is made of polyvinyl chloride as the main raw material, and the elastic spiral steel wire is implanted in the pipe wall to optimize the product, which is especially suitable for underground coal mine gas drainage system. , drilling and sealing, and other fields.

Features Of Coal Mine Underground Flexible Drainage Gas Rubber Hos Mining Hose

The gas drainage hose adopts spiral steel wire as the skeleton support, and has certain strength and hardness. The hose has good bending performance, is extremely convenient to install and use, and can be directly inserted with the outer diameter of the polyvinyl chloride hard pipe under the mine. After use, the hose clamp can be clamped; it has the dual performance of flame retardant and antistatic, and the double-resistance performance is durable. It is suitable for the connection between underground gas drainage pipes; corrosion resistance and no scaling.

Gas drainage hose product specifications

Gas drainage hose (inside diameter): φ20 φ25, φ32, φ40, φ44, φ50, φ63, φ75, φ90, φ110 φ115 φ120 φ125 φ130


The mine gas drainage hose is an environmentally-friendly plastic pipe. It uses polyethylene as the main raw material and adds appropriate amount of auxiliary agents such as flame retardant and antistatic. It is mainly used for gas drainage, ventilation, drainage and shotcreting in underground coal mines. Products with different specifications and different performances can be produced according to the actual needs of the underground, and there are also straight-through, three-way, elbow, and joints.


Advantages of Coal Mine Underground Flexible Drainage Gas Rubber Hos Mining Hose


1. High bendability: This tube is easy to bend around obstacles, which is convenient for downholes, reducing the amount of pipe fittings and reducing labor intensity.


2, high corrosion resistance: coal mine underground production environment is harsh, liquid corrosive, the tube can withstand a variety of chemical media corrosion.


3, flexibility and impact resistance: good toughness, high impact strength, heavy weight directly through the pipeline, pressure bearing capacity is better, will not lead to pipe rupture.


4. Good resistance to deformation: Under the same conditions, the tensile strength and elongation are higher than that of the steel pipe. When the local foundation is set, it can withstand a certain degree of deformation and keep it from breaking, but the steel pipe is very prone to fracture and collision. Sparks, creating unsafe hidden dangers.


5, flame retardant, antistatic performance is stable: with a special coupling agent against the static charge flame retardant additives surface activation, so that it forms a "molecular bridge" with the resin matrix, fusion into one, has a small amount of addition, reached Very good double-resistance effect.


6, the flow resistance is small: the wall finish is high, the friction coefficient is small, and the flowability of the pipeline is stronger than that of the steel pipe under the same flow rate.
