1.1 Project Overview
Honghuaerji water supply project to Honghuaerji Hydro as the source, through the 69km-long water pipeline water, flood storage settling, pressure works for the Yimin Power Plant, the super Evenki industrial water power plants, but also for Hulunbeier provide alternate sources of life.
1.2 Engineering Task
The project is located downstream hub on the prairie, the main task for the water line of the spiral welded to do inside and outside corrosion, non-toxic white wall corrosion using tungsten carbide plate-component epoxy ceramic coating, the model for GH102 type A, B component, the outer wall using two-component epoxy coal asphalt anticorrosive cold tapes, the construction of an anti-corrosion pipe length is 12000mm.
1.3 Construction Technology
Anti-corrosion construction process, this anti-corrosion steel pipe specifications DN2020 × 18 × 12000mm, DN1420 × 12 × 12000mm, DN1220 × 12 × 12000mm, DN1020 × 10 × 12000mm, DN820 × 10 × 12000mm, DN720 × 9 × 12000mm, DN630 × 9 × 12000mm, DN530 × 9 × 12000mm 8 kinds of specifications corresponding specifications of the various steel pipes and pipe fittings and external corrosion.
