MPP power protection tube
Product introduction:
Modified polypropylene (MPP) power tube without a lot of dredging, excavation and destruction of the pavement in roads, railways, buildings, riverbed inferior special section pipe laying, cables and other construction projects. With the traditional & ldquo; Wacao buried tube method & rdquo; compared to non excavation power pipe engineering more adapt to the current requirements of environmental protection, removal due to the traditional construction caused by dust, traffic congestion and other disturbing factors, this technology can also in some not implementation of excavation work in the laying of pipelines, such as Heritage Conservation District, downtown urban areas, crops and farmland protection areas, highways, rivers etc..
Modified polypropylene (MPP) power pipe with high temperature and external pressure, and is suitable for 10KV above high voltage transmission line and cable pipe line.. The common specifications of the tubes are outside diameter 11 O ~ 315, and are classified into ordinary and reinforced.. Ordinary type is suitable for excavation and construction and excavation crossing construction is less than 4M, and the strengthening type is suitable for construction of non excavation through deep construction and greater than 4M. This product has achieved good social and economic benefits through the testing of national chemical building materials testing center..
(two) application of scope:
Can be widely used in municipal, telecommunications, electricity, gas, water, heat and other pipeline engineering.
The engineering of the non excavation horizontal directional drilling in the urban and rural areas and the excavation of the power drain pipe project.
The engineering of the drainage drain line in the urban and rural areas of the non excavation horizontal directional drilling. Industrial wastewater discharge engineering.
(three) product superiority
(1) MPP power pipe having excellent electrical insulation.
(2) MPP power pipe with high thermal deformation temperature and low temperature impact performance.
(3) MPP power pipe tensile, compressive performance is higher than HDPE.
(4) MPP power tube light, smooth, friction heat, the main small butt welding.
(5) MPP power pipe for a long time using temperature of 5 ~ 70.
