Cement mortar anti-corrosion steel pipe manufacturer for water drainage

The cement mortar anti-corrosion steel pipe manufacturer designated for sewage treatment. Its main products are cement mortar-lined anti-corrosion steel pipes, cement mortar anti-corrosion spiral steel pipes for water supply pipelines, cement mortar anti-corrosion steel pipes for water supply projects, anti-corrosion steel pipes with three cloths and five oils on the outer wall, anti-corrosion steel pipes with one cloth and two oils. , three oil and two cloth anti-corrosion, anti-corrosion spiral steel pipe, etc. are complete in variety. Welcome to discuss adding stones in proportion to the cement mortar to become concrete. The graded strength of cement mortar refers to a value in the overall distribution of compressive strength measured using standard test methods at the age of cubic specimens made and maintained according to standard methods. The number of cement mortar means that its strength is /, but now it is all changed into units. The number corresponds to. The mix ratio varies according to the different uses of raw materials and mortar. Taking the commonly used ordinary Portland cement medium sand mixed with masonry mortar as an example, there are several labels for cement sand water cement mortar anti-corrosion pipes. Mortar is divided into several types according to its purpose, including masonry and plastering joints, and has nothing to do with the marking. After the cement mortar work is completed, there is the most important process, which is air drying. It means air-drying in a natural state. The main purpose is to prevent cracks in the cement mortar due to bumps during shipment! During the installation of cement mortar lined anti-corrosion pipes, our company has a good after-sales service team to provide customers with high-quality services. We will send technical engineers and technical workers from relevant departments to the construction site to arrange the installation and welding of the pipes! All expenses incurred during this period will be unilaterally borne by our company! We solemnly promise that all projects will be of high quality and quantity, and we will compensate you ten percent for every fake one! After all projects are completed, our company's construction team will supervise the trial process on site until they ensure that there are no problems in all project links before withdrawing! The company is responsible for all losses caused by the quality of the pipeline within one month from the date of withdrawal of the construction team
Cement mortar anti-corrosion steel pipes can be used in municipal projects, suitable for high-rise building water supply and heating networks, heating tap water projects, gas transmission, underground transmission Water and other pipes. Petroleum oil transportation pipelines, chemical, pharmaceutical, printing and dyeing and other industries are process pipelines for transporting corrosive media. Networks such as sewage treatment, sewage treatment discharge pipes, sewage pipes, bio-pool anti-corrosion projects, 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.
Cement mortar anti-corrosion steel pipe The mixture of cement, sand and water is called cement mortar. Usually the cement mortar is made of 1 part cement and 1 part sand. In fact, the water content is ignored. Generally, the proportion is about 100%, which is the purpose of cement mortar. In construction projects, one is foundation and wall masonry, It is used as an adhesive for block masonry materials. For example, cement mortar is used to build rubble red bricks. Secondly, it is used for indoor and outdoor plastering. When cement mortar is used, some additives such as microfoam waterproofing powder are often added to improve its workability and viscosity. When stones are added in proportion to cement mortar, it becomes concrete. The graded strength of cement mortar refers to a value in the overall distribution of compressive strength measured using standard test methods at the age of a cube specimen made and maintained according to standard methods. Cement mortar-lined anti-corrosion steel pipes are made of ordinary cement, yellow sand of a certain thickness and additives, mixed into a mortar according to the designed mix ratio, and then applied to the inner wall of the pipe through special construction machinery and equipment to form a mortar coating of a certain thickness. layer, which when solidified becomes the lining. The cement mortar lining relies on its own binding force and the support of the pipe wall. Its structure is uniform, dense, hard and firm. If epoxy resin is painted on the mortar surface, its roughness coefficient after water is passed through can be further reduced. Cement mortar lining is not only a simple barrier in terms of physical properties, but also protects pipelines through the chemical properties of cement mortar lining. The mortar layer is combined with the pipe to form a passivation area with a high value on the pipe wall. After water is passed through, the water penetrates into the cement mortar and is rich in alkaline components, so that the water no longer corrodes when it reaches the pipe wall.
How to deal with the anti-corrosion of on-site welded joints of cement mortar anti-corrosion steel pipes? The strength of cement mortar is /, but now it is all changed into units, and the number corresponds to. The mix ratio varies according to the different uses of raw materials and mortar. Take the commonly used ordinary Portland cement medium sand mixed with masonry mortar as an example of cement sand water. Cement mixed mortar is generally made of cement, lime, plaster, and sand, and is generally used for masonry above the ground. Due to the addition of lime paste, the mixed mortar improves the workability of the factory mortar and is more convenient to operate, which is beneficial to improving the density and work efficiency of the masonry.
