Silicon core pipe | Haotong Pipe | silicon core pipe procurement provided by the ho-pipe industry. Silicon core pipe | Haotong Pipe | silicon core pipe procurement is ho-Pipe Co., Ltd., Zhengzhou (www.zzhtgy.com) 2014 upgrade been newly launched Zhengzhou Haotong Pipe Co., Ltd., is a large Central Plains municipal sewer HDPE double One wall corrugated pipe production enterprises and low maintenance costs. Due to the above-mentioned glass pipe corrosion, abrasion and frost and dirt and other properties of silicon core pipe order, so the project does not require anti-rust, anti-fouling, insulation, insulation and other measures and maintenance. Without the need for underground pipe for cathodic protection, engineering and maintenance cost savings of over 70%. 8, good wear resistance. Silicon core contains a lot of water mud, sand tube news, rotate the tube into the impact of comparative wear test. After three million times the rotation, the inner wall of the test tube wear depth as follows: enamel coated with tar and steel is 0.53mm, and tar epoxy coated steel is 0.52mm, surface-hardened steel to glass pipe is 0.21mm. Thus fiberglass good wear resistance. 9, electric insulation. FRP is non-conductive silicon core pipe, pipe electrical insulation Premium insulation resistance at 1012-1015Ω.cm, best adapted for use in power transmission, telecommunication lines dense area of ??heat transfer coefficient and multiple small fiberglass minefield, only 0.23, is five thousandths silicon core steel pipe procurement, excellent insulation properties of the pipe. Zhengzhou, Henan Haotong Pipe Co., Ltd., is the Central Plains municipal drains relatively large double-wall corrugated HDPE pipe manufacturer of underground drainage steel reinforced polyethylene (HDPE) pipe continuous spiral corrugated steel pressed into the approximate shape of a spiral ^ steel ribs wrapped in heat-sealed between the inner and outer layers of polyethylene, the high degree of steel steel, high strength and flexibility of polyethylene, corrosion, wear together.
