Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron pipe, high quality ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells quality of our products. Brush oil pipeline flexible expansion joints in the pipeline pressure test should be qualified. The actual work is generally flexible expansion joints installed in the pipeline before the first pass of the paint brush, but to set aside part of ductile iron water pipe welding agent, to be installed and pressure test is completed and then complete a full paint job. Brush oil, dust, grease, rust and oxide surfaces you want to get rid of the pipe flexible expansion joints. Seam welding slag should be removed burrs. Metal surface sticky oil when more ductile iron water pipes, gasoline or available concentration of 5 ^ caustic soda solution cleared brush, and other dry before rust. If you do not clear the debris, the combined impact of the paint and metal surfaces. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron, ductile iron pipe, ductile iron pipe fittings of high quality flexible cast iron water pipe prices, cast iron pit wells quality of our products. Our pipeline applications and ductile iron water pipes wholesale started late last paved oil and gas pipelines is mostly Q235 16Mn steel. "Plan" period, China began to develop in accordance with API standard X60, X65 pipeline steel, and successfully used in conjunction with the imported steel pipeline laying. Early 1990s Baosteel, Wuhan Iron and have developed a high strength and high toughness X70 pipeline steel, and has been successfully applied in Shibuya ninglam pipeline project.
