The corrosion system of external prestressed steel cable involves a variety of corrosion methods and measures. First, the external prestressed system is a prestressed structure system formed by applying prestress on the prestressed reinforcement outside the main body of the load-bearing structure. The concept and method of this technique originated in France and was widely used in later engineering practice：
Features: the prestressed system consists of 54 or 55 steel strands, 15,7mm diameter as per PrEN10138-3, strength grade of 1860 MPa, 2 anchors devices (one at each end), cement grouting, two permanent caps for each anchor.
Prestressed tensioning must comply with relevant applications technical regulations and be carried out in strict accordance with the pre-programmed tensioning operating procedures.
A steel wire rope is a winding rope made of multiple or multiple strands of fine steel wire. It is made of multiple layers of steel wires twisted into strands, and then a certain number of strands are twisted into a spiral rope with the rope as the center. In material handling machinery, For lifting, pulling, tightening and carrying purposes. Moreover, the steel wire rope has high strength, light weight, stable operation, is not easy to break suddenly, and is reliable in operation.
IPN8710 special coating film for drinking water has the characteristics of non-toxic, high solid and low viscosity, and is a new type of anti-corrosion coating with strong adhesion, high strength, abrasion resistance, hydrolysis resistance, corrosion resistance, water resistance and excellent weather resistance.
The outer wall of TPEP anti-corrosive steel pipe adopts 3PE hot-melt winding process. (bottom epoxy, middle layer adhesive, outer layer polyethylene) an anti-corrosive layer or a single-layer polyethylene (PE) with a three-layer structure is formed, the inner wall adopts a thermal spraying epoxy powder anti-corrosive mode, the powder is uniformly coated on the surface of the pipe body after high-temperature heating and melting, the adhesive force of the coating and the thickness of the coating are improved, and the bump resistance is enhanced.
FBE is the abbreviation of FUSION BOND EPOXY. FBE coatings are available in single and double layers.
The inner and outer coated plastic steel pipe is a steel-plastic composite pipe composed of a layer of polyethylene (PE) resin, epoxy (EP) powder, non-toxic polypropylene (PP) and other organic matter in the inner and outer walls of the steel pipe.
