HOBAS pipe for its excellent corrosion resistance, water resistance characteristics, lightweight, high strength, transport flow, easy installation, short construction period and comprehensive advantages of low investment, HOBAS pipes chemical industry and become the best choice for drainage works . HOBAS pipes PERFORMANCE: High strength: resistance to external load capacity, can be used directly buried under the carriageway, without constructing concrete protective layer, can speed up the construction progress, and thus greatly reduce the construction cost, with significant social economic benefits. Corrosion: specially designed RPMP resistant to acid, alkali, salt, untreated sewage, corrosive soil and groundwater, and many other chemical fluid erosion, long life through traditional channels, its design service life more than 50 years. Flame, heat frost resistance: HOBAS -20 ℃ -100 ℃ in long-term use without deformation. Glass pipe Features: 1, glass pipe corrosion-resistant ability, insulation, non-magnetic, acid and alkali, but resistance antistatic. 2, a good glass pipe FRP pipe water power performance, long-term use in wet or water is not bad. 3, due to the specific properties of glass pipe FRP, the FRP pipe life of more than 50 years. 4, glass pipe construction side glass will, in particular when the repair works, the efficiency is particularly prominent, is the power cable engineering, communications cable engineering, municipal engineering and road laying underground cable ideal protection devices.
