In coal mine underground drainage gas rubber hose
Structure: drainage of gas hose from the sub, with metal spiral (or metal ring) fabric reinforced layer and external rubber cover, and ends with a connecting flange and gasket.Glue inside so low resistivity, antistatic, rubber cover is at the same time of antistatic and flame retardant, maximum limit to ensure the safety production.
Characteristics: this product is compared with the traditional drainage gas pipe is light weight, convenient handling, good elasticity, good impact resistance, high safety, strong and durable.For both the company contains ingredients of antistatic, flame retardant additives, can be in downhole inflammable, explosive used in the particularity of the place.Rubber hose has good elasticity connection is convenient, is suitable for short distances and the coal mine drainage gas pipe connection, greatly reduces the consumption of manpower and material resources in the process of installation.And has wear-resisting, anti-aging performance, can prolong the service life of the hose.
Standard:HG/T 2490-93, suction rubber hose, MT 191-89 with a rubber hose in mine safety inspection gauge, Q/HYTJ 01-2011 coal mine drainage gas rubber hose
Application: for the coal mine drainage gas rubber hose.Of the coal mine with a rubber hose can be used in the coal mine drainage gas drainage gas, its length is not more than 10 m, and can be used for the coal mine drainage gas (hard) pipe connection, but may not be directly used in the coal mine drainage gas and other purposes.
Temperature: - 20 ℃ ~ 80 ℃.
