As we all know, compared with general pipeline products, plastic-lined pipelines are far better than general products in terms of performance and practical utility. It is also for this reason that this product is often used in the current industrial production field for the transportation of raw materials or products. The steel lined tetrafluoride pipeline, as one of the representative pipelines, should be paid more attention in the use process.

In the actual industrial production field, the corrosiveness of different types of production media is often different, but without exception, the anti-corrosion requirements of transportation pipelines are very high. Take steel lined tetrafluoro pipeline products for example, even if the pipeline's anti-corrosion performance is outstanding, if used improperly, not only the pipeline itself may be corroded, but also serious leakage may occur. So how can this situation be effectively avoided?

From a professional point of view, the practical application of fluorine-lined pipeline is a composite steel pipe made of a variety of modified blended polymer and steel pipe by special technology. It not only retains the strength of steel pipe and traditional connection methods, but also through different modifications of plastic materials, fully exerts the corrosion resistance, aging resistance and high performance of plastic materials. Wear-resistant, rust-free, non-toxic, smooth inner wall and other characteristics. The modified corrosion-resistant plastic-lined pipeline is a substitute product for industrial pipelines in petroleum, chemical, power, coal, ship and wharf industries.

In fact, for steel-lined tetrafluoro pipeline products, the main media that can really cause the corrosion of products are chloride corrosion to carbon steel, which is basically uniform corrosion. The tetrafluoro pipeline is accompanied by hydrogen embrittlement. The corrosion of pipeline is pitting corrosion or intergranular corrosion. Its effective prevention measures can choose suitable materials, such as Carbon steel-stainless steel composite pipe is used.

Steel lined tetrafluoride pipeline is an effective material to resist naphthenic acid corrosion, which is often used in high temperature naphthenic acid corrosion environment. Thermal shrinkage for anti-corrosion lining of tetrafluoroethylene pipelines can be bonded tightly even if there are depressions on the surface or other protective materials covered by the pipeline. The pipeline lined with tetrafluoro has good waterproof vapor permeability, chemical corrosion resistance and aging resistance. It is an ideal insulating anticorrosive material.

As the general plastic-lined pipeline is based on ordinary carbon steel pipe and lined with thermoplastic with excellent chemical stability, it has not only the mechanical properties of steel pipe, but also the corrosion resistance of plastic pipe, slow scaling, and not easy to grow microorganisms. It is characterized by conveying acid, alkali, salt and corrosiveness. Ideal pipe for medium such as gas.

The steel lined tetrafluoroethylene pipeline is composed of radiation crosslinked polyethylene and special hot melt sealant, which has the function of "shape memory". After heating, the melted hot melt adhesives are evenly squeezed into the weld to form a perfect sealing surface, which is tightly contracted and coated at the pipe interface or anticorrosive components.

As the steel-plastic composite pipes and pipe fittings are easy to be damaged, the leakage areas are: the right-angle part of the straight pipe flange, the middle part of the long pipe, the junction part of the main branch pipe of the tee and the center position of the elbow. Therefore, users often need to start from these aspects in the prevention of pipeline leakage.
