Cement mortar lined anti-corrosion steel pipe

    There are several grades of mortar, including M3, M5, M7.5, M10, M12.5, M15, M20, M25, M30, and M40. Mortar can be divided into several types according to its purpose, including masonry, plastering, and joints, regardless of the grade. The most important process after the completion of cement mortar work is air drying. It refers to 2-3 days of wind drying in State of nature. Mainly to prevent cracks in cement mortar caused by bumps during shipment!
    Due to the fact that the steel pipe is filled with concrete and can absorb a large amount of heat energy, the distribution of the temperature field on the cross-section of the column is very uneven during a fire, which increases the fire resistance time of the column and slows down the heating rate of the steel column. Once the steel column yields, the concrete can withstand most of the axial load to prevent structural collapse. The fire resistance of composite beams will also increase, as the temperature of the steel beam will transfer heat from the top flange to the concrete and decrease. According to experimental statistics, achieving the 3-hour requirement of first level fire resistance can save 1/3 to 2/3 or even more of the fireproof coating compared to steel columns. As the diameter of the steel pipe increases, the more coating can be saved.

    High bearing capacity, good ductility, and superior seismic performance.
    Cement mortar lined anti-corrosion steel pipes are used in municipal engineering: suitable for high-rise building water supply, heating network, tap water engineering, gas transmission, buried water transmission and other pipelines. Petroleum: Process pipelines for transporting corrosive media in industries such as petroleum transportation pipelines, chemical pharmaceuticals, printing and dyeing.
    Sewage treatment: sewage treatment discharge pipes, sewage pipes, and biological pool anti-corrosion engineering. Agriculture: agricultural irrigation pipes, deep well pipes, drainage pipes, and other networks have better corrosion resistance than steel structures, which is beneficial for the fire resistance and fire prevention of steel pipes

    A mixture of cement, sand, and water is called cement mortar. The commonly used 1:3 cement mortar is a mixture of 1 part cement and 3 parts sand, but in reality, it ignores the composition of water and is generally around 0.6, which should be 0.6:1:3
The purpose of cement mortar in construction engineering is to use it as an adhesive for block masonry materials in foundation and wall masonry. For example, cement mortar should be used for building rubble and red bricks; The second is for indoor and outdoor plastering.
    When using cement mortar, some additives such as micro foaming agents and waterproof powder should be often added to improve its workability and viscosity.
