Features advantages:
1. To avoid the corrosion and scale on the inner wall of the pipeline, to keep the pipeline in a good water delivery state for a long time, and to reduce the friction coefficient.
2. Due to the isolation of the lining coating, the water body does not contact with the metal pipeline, ensuring the water quality.
3. The inner wall of the pipeline is anti-corrosion by cement mortar, which prevents corrosion perforation, prolongs the service life of the pipeline, and is lined with cement mortar anti-corrosion elbow, water supply cement anti-corrosion elbow,
4. The material of cement mortar coating is easy to obtain, the construction period is short, the anti-corrosion effect is good, and the cost of pipeline engineering is reduced
The R & D and production process of cement mortar anti-corrosion steel pipe:
1. First, the steel pipe to be anti-corrosion shall be subject to rust removal;
2. The cement mortar mixed in proportion shall be used to form cement coating on the steel pipe through centrifuge or pipe spraying machine.
3. Detect the cement anti-corrosion coating and repair the anti-corrosion coating missing at both ends of the steel pipe;
4. After the completion of the cement mortar anti-corrosion steel pipe work, an important work should be done, air drying, that is to say, air drying in the natural state for 2-3 days, usually to prevent the cement mortar from appearing cracks due to bumping on the way of shipment. The structural feature of cement mortar lined anti-corrosion spiral steel pipe is to enhance the mechanical properties of the anti-corrosion coating. It can be applied at room temperature, naturally solidified, and easy to construct, which is very suitable for field use
