Cement mortar steel pipe manufacturer

Description :

　　The cement mortar lining is made by mixing ordinary cement with a certain thickness of yellow sand and additives according to the designed mix ratio, and then applying it to the inner wall of the pipeline through specialized construction machinery and equipment to form a certain thickness of mortar coating. After solidification, it becomes the lining. The cement mortar lining, relying on its own bonding force and the support of the pipeline wall, has a uniform, dense, hard and firm structure. If epoxy resin is applied to the surface of the mortar, its roughness coefficient after water flow can be further reduced. Cement mortar lining is not only a simple physical barrier, but also protects pipelines through the chemical properties of cement mortar lining. The mortar layer is combined with the pipeline to form a passive area with a pH value of up to 12 on the pipe wall surface. After water is supplied, the water seeps into the cement mortar, which is rich in alkaline components, making the water no longer corrosive when it reaches the pipe wall.

　　Epoxy coal tar anti-corrosion steel pipe is a type of pipeline with excellent anti-corrosion ability. Epoxy coal tar anti-corrosion steel pipes are coated with epoxy coal tar anti-corrosion paint, which is made of epoxy resin, anti rust pigments, additives, and modified amines. This paint is dry, agile, has good adhesion, flexibility, two-component packaging, and is easy to apply. It has the advantages of acid resistance, alkali resistance, salt resistance, water resistance, oil resistance, etc. It is a high-performance anti-corrosion insulation coating that is resistant to water, heat and humidity, can expand and shorten with the coated object, and can also change its main direction to a certain extent by adding different fillers to adapt to different environments. It is widely used in the anti-corrosion of oil, gas, water pipelines, tap water, gas, pipelines, refineries, chemical plants, and sewage treatment plants. It can also be used as a corrosion prevention and mining tool for offshore oil drilling channels and underwater vessels Corrosion prevention of underground equipment.
