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. Alloy impurities: Center impurity element Bi, Te and Tl is less than 0.5 × 10-6Ag), and lead, tin is less than 5 × 10 -6, the impurity element types up to 40, in addition to the hub of the impurity element, other impurities The number of elements is less than 10-400x6; single impurity content of more than 25 × 10-6. Needs are different, of course, different materials, different parts, but the overall trend is limited gaseous impurities in the alloy is getting worse, preparation of high purity alloy development needs of emerging ductile iron pipe specifications, such as the preparation of high-purity alloys In718 is a crucial part. 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. 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 emerging ductile iron pipe valves and pipes wholesale, easy valve removal. 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. Ductile iron pipe] [Bozhou emerging, emerging ductile iron pipe wholesale, Shunxiang ductile pipe provided by Shunxiang ductile pipe. Welcome to consult Liaocheng Shunxiang Building Materials Co.
