PE-ZKM mine detection beam by beam pipe fittings a coal mine detection beam PE PE pipe coal, coal use polyethylene pipe bundle beam tube is mine monitoring system is an important component. Suitable for coal mine gas sampling. 2 Features of polyethylene flame retardant, antistatic Compound or pure polyethylene particles become polyethylene extrusion through a single tube, several root polyethylene single tube (called a core tube) through a combination of cable tie around the cloth wrapped around one, In the outer layer made of extruded polyethylene jacket. Each core tube label (or separation) clearly legible. Mine is black polyethylene tube bundle, with light weight, good flexibility, acid, corrosion-resistant, antistatic, flame-retardant properties, impact resistance, high pressure, air tightness, serialization sets and strong Features; different specifications can be customized according to user requirements and length, can be divided according to their needs when in use. 3. Category beam tube diameter can be divided according to the core tube 8mm, 10mm two categories, according to the number of tubes can be divided into a core-core, two-core, three-core, four-core, five, six-core, seven core, eight-core ten core, twelve core, sixteen cores, eighteen core, core nineteen twenty core Twenty-four-core, core thirty, thirty-second core and other 17 kinds. Also can be customized in different sizes and lengths according to user requirements. 4. Working conditions for the use of pressure: ≤1.0MPa; working environment conditions: Ambient temperature -10 ℃ ~ 40 ℃; relative humidity of 30% to 90%.
