Analysis of the excellent performance of cement mortar anticorrosive spiral steel pipe
In the manufacture of cement mortar anti-corrosion spiral steel pipe because the steel pipe is filled with concrete, so it can absorb a lot of heat energy, the raw materials are mainly cement, sand and water mixture is often referred to as cement mortar. The specification of cement mortar anti-corrosion spiral steel pipe is 325-2400mm. The ratio of cement mortar is 1 part cement and 3 parts sand, which actually ignores the composition of water.Mortar by use of masonry, plastering, joint several, and no.After the completion of the cement mortar work there is the most important process, that is, air drying.The main purpose is to prevent the cement mortar from cracking due to the turbulence during shipment.Cement mortar lined anticorrosive steel pipe is used in municipal engineering: it is suitable for high-rise building water supply, heat supply network, tap water engineering, gas transmission, buried water transmission and other pipelines.Petroleum: petroleum transportation pipeline, chemical industry, pharmacy, printing and dyeing and other industries conveying corrosive medium process pipeline. Sewage treatment: sewage treatment discharge pipe, sewage pipe and biological pool corrosion protection engineering agriculture: agricultural irrigation pipe, deep well pipe, drainage pipe network, corrosion resistance is better than steel structure is conducive to the fire resistance and fire prevention of steel pipe.The main production base in hebei cangzhou.The nominal strength of cement mortar refers to the overall distribution of compressive strength measured by the standard test method in the 28d phase of the cube specimen made and cured in accordance with the standard method.The main implementation standards are SY/ t0447-96;GB50268-97;CECS10:89;DIN30670, DIN30671, SY/ t0413-2002, SY/ t0315-97.
