Cement mortar anti-corrosion steel pipe
- Commodity name： Cement mortar anti-corrosion steel pipe
- Product Description
-
Cement mortar anti-corrosion steel pipe is a pipe material lined with a cement mortar layer inside the steel pipe, which combines the high strength of steel pipe and the anti-corrosion performance of cement mortar. It is mainly used in pipeline transportation systems in the fields of water supply and drainage, petroleum, chemical industry, etc., especially suitable for the transportation of high flow fluids. This design can effectively prevent corrosion inside the pipeline, improve the service life of the pipeline and the quality of the transported medium.
Material and Performance
The matrix of cement mortar anti-corrosion steel pipes is usually made of high-quality carbon structural steel or low-alloy structural steel, such as Q235B and Q345B. Q235B steel has good strength and toughness, with a yield strength of about 235 MPa and a tensile strength between 370-500 MPa; Q345B steel has a higher yield strength, approximately 345MPa. These steels provide solid mechanical support for the pipeline, ensuring that it can withstand internal pressure, external loads, and stresses during installation.
Craftsmanship
The key steps in making cement mortar anti-corrosion steel pipes include surface treatment of the steel pipes, preparation of mortar, and coating and curing. The surface of the steel pipe needs to be cleaned to remove oil stains, rust, and other impurities to ensure the adhesion of the mortar. The preparation of mortar requires the selection of appropriate proportions of cement and sand according to specific engineering requirements. The cement mortar anti-corrosion steel pipe with anti-corrosion function is formed by uniformly coating the mortar on the surface of the steel pipe and curing it for a certain period of time.
Application scenarios and advantages
Cement mortar anti-corrosion steel pipes are widely used in fields such as water supply and drainage, petroleum, and chemical engineering, especially for the transportation of high flow fluids. Its advantages include:
● Anti corrosion performance: The cement mortar lining provides both physical and chemical protection for the steel pipe, isolating it from the conveying medium and preventing direct contact between the medium and the steel pipe from causing corrosion.
● Wear resistance: The cement mortar lining has good wear resistance and can resist the erosion of solid particles in the fluid inside the pipeline, reducing the wear of the inner wall of the pipeline.
● Long service life: Through effective anti-corrosion measures, the service life of cement mortar anti-corrosion steel pipes is significantly extended, usually up to 20-30 years.
