Cement mortar anti-corrosion spiral steel pipe Because the steel pipe is filled with concrete, it can absorb a large amount of heat energy. The raw material is mainly a mixture of cement, sand and water, which is often called cement mortar. The specifications of cement mortar anti-corrosion spiral steel pipe are - the proportion of cement mortar is 1 part cement and 1 part sand, which actually ignores the water component. Mortar can be divided into masonry, plastering, and joints according to its uses, regardless of the number. After the cement mortar work is completed, the most important process is air drying. The main purpose is to prevent cracks in the cement mortar due to bumps during shipment. Cement mortar lined anti-corrosion steel pipes are used in municipal projects: suitable for high-rise building water supply, heating network heating, tap water projects, gas transmission, underground water transmission and other pipelines. Petroleum: process pipelines for transporting corrosive media in petroleum transportation pipelines, chemical pharmaceuticals, printing and dyeing and other industries. Sewage treatment: Sewage treatment discharge pipes, sewage pipes and bio-pool anti-corrosion projects Agriculture: Agricultural irrigation pipes, deep well pipes, drainage pipes and other networks have better corrosion resistance than steel structures, which is beneficial to the fire resistance and fire prevention of steel pipes. The main production base is in Cangzhou, Hebei. The strength of the cement mortar label refers to the overall distribution of compressive strength measured using standard test methods at the d age of cube specimens made and cured according to standard methods. The main implementation standards are /--: D, D, /-, /-. The cement mortar anti-corrosion spiral steel pipe also has good corrosion resistance and impact resistance under low temperature conditions and can be directly buried in underground frozen soil.
