3pe chemical corrosion steel pipe, 3pe oil pipe corrosion, 3pe anticorrosive steel smelting, 3pe anticorrosive steel water conservancy 3pe steel pipeline corrosion www.2pe3peguan.com Feng Steel Co., Ltd. Changzhou Guanghui manager 13,833,775,392 through the creation of two generations additional 2 pipeline external corrosion production line has reached nine pipe production lines, can be processed: 2pe / 3pe anticorrosive steel 2PP / 3PP anticorrosive steel FBE / 2FBE anticorrosive epoxy powder cement mortar lined steel coal tar epoxy anti-corrosion steel pipe drinking water, non-toxic preservative ipn8710 epoxy anti-corrosion steel pipe polyurea corrosion epoxy anti-corrosion steel pipe anti-corrosion epoxy micaceous iron pipe chlorinated rubber solvent-free anticorrosive epoxy anti-corrosion steel pipe anti-corrosion steel pipe and other products HT515 glass flake epoxy anti-corrosion steel pipe corrosion, etc., according to customer needs using a variety of materials seamless steel pipe spiral pipe straight seam steel pipe. Select 3PE anti-corrosion pipe mending methods 3PE anti-corrosion steel site field joint is first necessary to weld at the polished surface roughness, no rust, and then fill the mouth parts of the flame heater to warm up. In accordance with the requirements of the product specification and control of preheating temperature mending construction. For the convenience of on-site fill the mouth, ≤30 ° chamfer end to end surface of the coating to be formed to stay. Polyethylene coating damage the outer surface of the pipe, should be polished clean damage around, the first hot melt adhesive applied to the strip surface, and then welded or extruded with polyethylene tubing of the same material sheet was subjected to hot-melt patches. After cutting off the pipeline, at the crest of steel fracture site should be used or extrusion welding and pipe the same material polyethylene sheet was fracture sealing and corrosion protection. Mending construction methods in strict accordance with SY / T0413-2002 Mending request execution. (4) under the frost, dew, wind and other weather conditions can not be anti-corrosion construction site. (5) 3PE anti-corrosion steel pipe using the original soil buried pipeline infrastructure, such as the case of backfill or ditches, ponds, silt foundation treatment area should be done. Pipeline construction encountered more complex ground conditions, there have been landslides and pipeline issues on the basis of the arch. Been taken while playing set steel sheet pile, while ground handling, while the down tube, while backfilling solution to solve the problem of landslides and arch pipes basis. Also take a different foundation treatment. Figure 2 is a site set up to fight landslides and sheet piles. Polyurethane foam pipe insulation general principle of this project is the use of ground treatment program based substrates pipe replacement method to do silty clay layer bearing stratum, silty clay layer above section should drain dredging, gravel Replacement (Replacement cushion to the bottom of the upper part of the pipe aside pipeline infrastructure required thickness: 400mm thick gravel + 200mm thick sand cushion). When local rain drains below the bottom elevation of silty clay layer, to silt clay layer, buried steel sleeve steel steam pipe insulation should throw rubble reinforced silty clay surface, for sand and gravel to fill the design elevation (Cushion the upper part of the pipe to the bottom of the pipeline infrastructure needed to set aside a thickness: 400mm thick gravel + 200mm thick sand cushion base). To ensure the stability of the tube base, segmented fight dam, dredging drainage. In order to reduce the longitudinal differential settlement, laying geogrid in the substrate. Guanghui Cangzhou Pipe Co., Ltd. (HSBC Manager: 13833775392) with full enthusiasm, very hard to make high-quality products, we warmly welcome new and old customers and friends to inquire, to guide, to discuss cooperation and win-win with the king.
