Product Name: Polyethylene beam tube retardant antistatic PE-ZKW / 8 × 20 PE-ZKW / 8 × 20 coal polyethylene beam tube --- polyethylene flame retardant, antistatic special materials by extrusion of polyethylene particles processing and become a single tube of polyethylene, polyethylene single tube several root (called a core tube) through a combination of cable tie around the cloth wrapped around one in extruded outer jacket made of polyethylene or polyvinyl chloride. Mine --- each beam tube with polyethylene core tube label (or separation) clearly legible. Mine is black polyethylene beam tube, light weight, good flexibility, acid, corrosion-resistant, antistatic, flame retardant, impact resistance, high pressure, air tightness, serialized sets, and other characteristics ; various specifications can be customized according to user requirements and length can be divided according to their own needs when in use. Mine polyethylene beam tube --- suitable for coal mine gas sampling. Mine beam tubes with polyethylene pipe can be divided by the core tube diameter 8mm, 10mm two categories, according to the core tube can be divided into a number of core, two-core, three-core, four-, five-, seven-core, eight-core, ten core, twelve cores, sixteen cores, nineteen cores twenty-two kinds. Conditions of use: coal polyethylene using a beam tube --- Working pressure: ≤ 1.0MPa coal polyethylene beam tube --- working environment conditions: Ambient temperature -10 ℃ ~ 40 ℃; relative humidity of 30% ~ 90 % coal polyethylene beam tube model specifications: the use of coal by the beam tube, core tube and sheath material, nominal beam tube with polyethylene Model OD, core number to divide the specification format is: PE-□ □ - □ × □. The above specifications '□' were:.... A main material - PE Polyethylene, b uses - mine beam tube ZKM, c core tube diameter (mm), d core tube number (root).
