Cement mortar lining anti-corrosion steel No. 100 refers to its cement mortar strength is 100kg / cm2, but now all into units of MPa, and 100 corresponding to the M10. Depending on the mix of raw materials, mortar use varies, the usual 42.5 ordinary portland cement, sand with 100 (M10) mortar example: cement 305kg: sand 1.10m3: water 183kg. Mortar labels have M3, M5, M7.5, M10, M12.5, M15, M20, M25, M30, M40 several. Divided by end-use mortar masonry, plastering, several unrelated seams, and labels. After the completion of cement mortar and most importantly a process, it is dry. Refers to air-dry for 2-3 days in the natural state. The main way to prevent the shipment of cement due to the bumps cause cracks! Because steel pipe filled with concrete, can absorb a lot of heat, so the string section when subjected to fire temperature field distribution is very uneven, increasing the pillar of fire-resistant, slow heating rate of steel columns and steel columns once yielded concrete Most can withstand axial load, to prevent structural collapse. The fire resistance of composite beam will increase as the temperature of the steel beam from the top flange of the heat will be transferred to the concrete increases. The experimental statistics show: up to 3 hours fire resistance level requirements can be saved and compared with fire retardant coating steel columns 1/3 a 2/3 or even more, with the pipe diameter increases, saving the more paint. High capacity, ductility, seismic performance of steel for superior corrosion protection: public works: for high-rise building water supply, heat supply network, water supply projects, gas transportation, underground water and other pipelines. Oil: Oil pipeline, chemical and pharmaceutical, printing and dyeing industry, transport process piping of corrosive media. Sewage: Sewage discharge pipes, sewers and biological corrosion engineering pool Agriculture: Agricultural irrigation pipes, deep well pipes, drains and other networks, corrosion resistance than steel pipe in favor of anti-fire and mortar fire anti-corrosion Pipeline: a mixture of cement, sand and water, called cement mortar. Commonly referred to as 1: 3 cement mortar with 1 part cement and 3 parts sand with, in fact, ignoring the composition of the water, usually in the ratio of about 0.6, which should be 0.6: 1: 3 cement mortar use in construction projects in, first base and wall masonry, masonry block used as an adhesive material, such as masonry rubble, red brick to use cement mortar; the second is used for interior and exterior plastering. Cement mortar when in use, they often incorporated additives such as micro-foaming agent, waterproofing powder to improve its workability and viscosity. Cement mortar in proportion to join the stones, they become concrete. Grade cement mortar strength is meant by standard methods for the production and maintenance of the cube specimens, in 28d age, a value measured by Standard Test Method for Compressive Strength of the overall distribution. Wherein the device includes a steel shot blasting machines, three PE winding equipment, PE pipe black and yellow jacket pulling machines, sand-blasting equipment, polyurethane Low Fat Kee, foam platform, FRP winding machine, two PE coating, cement corrosion insulation mortar spraying machines and other ancillary testing equipment. The company can undertake single and double steel pipe fusion bonded epoxy powder (FBE), double polyethylene (2PE) and three polyethylene (3PE), double polypropylene (2PP), and three poly propylene (3PP), coal tar epoxy pipe coating, polyurethane prefabricated buried pipe insulation, black and yellow jacket pipe insulation, IPN8710 corrosion anti-corrosion coating polymer, epoxy pipe corrosion, high-density polyethylene pipe corrosion, corrosion of cement mortar lining, prefabricated buried pipe insulation corrosion and other projects. Execution SY / T0447-96; GB50268-97; CECS10: 89; DIN30670, DIN30671, SY / T0413-2002, SY / T0315-97 standards. Depending on the product quality of life for enterprises, the establishment of a sound quality assurance system, has passed ISO9001: 2000 certification, we track the quality control from raw materials, rust, applied to the whole process of manufactured products. Improve the quality management system and advanced testing equipment to provide users with high-quality products to provide a reliable guarantee. Steel components performance under loads or have a certain influence. As for the aspect of deformation, stability, anti-fatigue and so are likely to have adverse effects. Hot-rolled steel products, poor control of the thickness and width of the edge in this regard. We are familiar with thermal expansion and contraction, due to the beginning of the hot-rolled out of even length, thickness are standard, and finally cooled or there will be some negative difference, this negative differential edge width wider, the thicker the more obvious manifestations. So for large steel, steel edge for width, thickness, length, angle, and no law requires very precise edges.
