Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of flexible milling cast iron pipe ductile iron pipe factory price, high quality ductile iron to ductile iron pipe manufacturer of flexible pipes, flexible cast iron pipe fittings, cast iron pit wells quality of our products. 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 pipe, high quality ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells quality of our products. GB estrangement pressure gauge can be flexible ductile iron pipe manufacturers, currently has between 2 titanium and molybdenum, tantalum film, diaphragm and ballistic pressure transmission pipe with methyl silicone oil, the minimum range can be 0 ~ 100kPa, if the diaphragm data also does not decay, you can add a layer of F46 (fluorinated ethylene propylene) membrane, but the appearance of active end declined. F46 can also be used directly as a resistance barrier film, but pay attention to the medium permeability, can be used to pass liquid fluorine oil, you can play two barrier effect.
