Gas drainage hose model

Description :

　　Gas drainage hoses are mainly used for flexible connections between negative pressure gas drainage pipelines and devices in coal mines. They have good bending performance and solve the problem of air tightness between hard pipes and devices for negative pressure gas drainage in coal mines. They have the advantages of easy installation, use, flame retardancy, and anti-static properties The gas drainage hose is mainly made of polyvinyl chloride, and elastic spiral steel wire is implanted in the pipe wall to make it productized. It is particularly suitable for use in coal mine underground gas drainage systems, drilling and sealing external connections, and other fields.

　　Product characteristics of gas drainage hose

　　The gas drainage hose is supported by a spiral steel wire skeleton, which has a certain strength and hardness; This hose has good bending performance and is extremely easy to install and use. It matches the outer diameter of PVC hard pipes used in mines and can be directly inserted and clamped with a hose clamp; And it has dual properties of flame retardancy and anti-static, with long-lasting dual resistance, suitable for connecting hard pipes for underground gas drainage; Corrosion resistant and non scaling.

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

　　Mining gas drainage hose is an environmentally friendly plastic pipe made mainly of polyethylene and added with appropriate flame retardant, anti-static and other auxiliary agents. Mainly used for gas drainage, ventilation, drainage, and spraying in coal mine boreholes. We can produce products of different specifications and performance according to the actual needs underground, as well as matching straight, three-way, elbow, connection, etc.

　　Advantages of gas drainage hose products

　　1. High bendability: This pipe is easy to bend around obstacles, making it convenient to go down the well, reducing the amount of pipe fittings, and lowering labor intensity.

　　2. High corrosion resistance: The production environment underground in coal mines is harsh, and the corrosiveness of liquids is high. This pipe can withstand corrosion from various chemical media.

　　3. Strong flexibility and impact resistance: With good toughness and high impact strength, heavy objects can be directly pressed over pipelines, resulting in good pressure bearing capacity and preventing pipeline rupture.

　　4. Good resistance to deformation: Under the same conditions, the tensile strength and elongation are higher than those of steel pipes. When the foundation settles, it can withstand a certain degree of deformation without breaking, while steel pipes are prone to breakage, causing sparks upon collision and posing safety hazards.

　　5. Flame retardant and anti-static performance stability: Special coupling agents are used to activate the anti-static flame retardant additives on the surface, forming a "molecular bridge" with the resin matrix and fusing into one. With a very small amount of addition, it achieves good dual resistance effect.

　　6. Low flow resistance: The pipe wall has high smoothness and low friction coefficient. Under the same flow rate, the pipeline has stronger flow resistance than steel pipes. zmjt063
