Flexible pipe expansion joints long unwashed, rusting occurs, there will be long and expansion joints parts rusting. Flexible pipe expansion joints rust rust artificial, mechanical descaling and pickling rust. Flexible expansion joints in pipes rust using a wire brush or artificial emery cloth. Electric machinery rust rust remover, rust various electric tools or sandblasting method. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron pipes, ductile iron water pipe flexible high-quality ductile iron pipe specifications, flexible cast iron pipe fittings, cast iron pit wells quality of our products. Ductile iron pipe fittings rubber seals installed incorrectly, causing friction due to the large apron from its original position when the ductile iron pipe fittings for installation. Because in the transport, lifting process is not standardized operation, resulting in loss of round socket, causing installation difficulties. Such cases are rare, for out of round ductile iron pipe fittings, special tools required to carry out round the school. Commonly used lubricant because soapy water, which almost no lubrication under water trench or higher temperatures, in this case we generally use higher viscosity oils as a lubricant.
