Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron pipes, ductile iron pipes ductile iron pipe water supply specifications, quality and flexible ductile iron pipe fittings of cast iron water pipe prices, cast iron pit wells quality of our products. Pressure gauge can be barriers, currently with methyl silicone pressure transmission between two titanium and molybdenum, tantalum film, diaphragm and trajectory control, the minimum range can be 0 ~ 100kPa ductile iron pipe water supply, if the diaphragm data also intolerant rot, 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. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling ductile iron pipe water supply cast iron pipe bends, ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells quality of our products quality. Flexible pipe expansion joints GB/T12465-2007 national standard is the latest standard pipeline equipment, using the latest standard products manufactured steel expansion joints and pipe connections can adapt to compensate for valves and piping, valves for easy disassembly. Expansion joints shall meet all kinds of pressure piping systems may be encountered due to quick closing valves, the system may encounter positive and negative pressure, respectively: maximum positive pressure: 1.0MPa. Maximum vacuum:-0.10MPa. Brushing requirements for the two end-face, dry film thickness of not less than 210. [DN450 ductile iron pipe water], ductile iron water pipe elbows, Shunxiang ductile pipe provided by Shunxiang ductile pipe. Welcome to consult Liaocheng Shunxiang Building Materials Co.
