Features of Cement mortar lining anticorrosive spiral steel pipe

Cement mortar lining anticorrosive spiral welded steel pipe structure features:

The high compressive strength of concrete, but the bending ability is very weak, and steel, especially steel bending capability is strong, good plasticity, but easily when compression instability and loss of the axial compressive capacity. The concrete filled steel tube in structure can combine the advantages of the two together, can make the concrete in the lateral compression state, its compressive strength can become

Times. At the same time because of the existence of concrete can increase the stiffness of the carbon steel pipe, both play a role, so as to greatly improve the bearing capacity. Concrete filled steel tube as a new composite structure, mainly by the axial compression and forces smaller eccentric compression member is given priority to, has been widely used in frame structure.

Cement mortar lining anticorrosion spiral steel tube components for cement mortar lining anti-corrosion coating steel pipe anticorrosion primers and paint, are based on epoxy resin and coal tar as the main film-forming material, add various kinds of antirust paint, insulation fillers, toughening agent, flow ping agent, diluent, anti-settling agent and B component is modified amine curing agent or hardener as main ingredient, adding fillers. This product sales of A and B component matching supply, construction proportionally mixed, mix after finished within the prescribed time.
