Tpep anti-corrosion steel pipe manufacturer for pipelines

Tianyuan Anti-corrosion Steel Pipe Co., Ltd. Manager Zhang Anti-corrosion Steel Pipe Manufacturer Product Introduction: The full name of anti-corrosion steel pipe is: outer-wound polyethylene and inner sintered epoxy anti-corrosion pipe. Name interpretation: outer-wrap polyethylene refers to the anti-corrosion treatment on the outer wall of the pipe, with two layers. A layer of epoxy powder, a layer of adhesive, and then a layer of polyethylene winding. Internal sintered epoxy refers to the anti-corrosion treatment of epoxy resin powder on the inner wall of the pipeline. It refers to the use of high-temperature sintering production processes to sinter the epoxy resin powder. Coating the pipeline. The product solves the problem of adhesion of the outer single layer of polyethylene to the steel pipe. At the same time, the anti-corrosion standard of the inner wall has reached food grade.
Anti-corrosion pipelines can be divided into two categories, lined with anti-corrosion steel pipes and outer wall anti-corrosion Steel Pipe. The main anti-corrosion lining is cement mortar lined anti-corrosion steel pipes, which are widely used and have lower costs. Cement mortar-lined anti-corrosion steel pipes use the cement mortar anti-corrosion layer to play an anti-corrosion role on the pipeline. Anti-corrosion pipes with outer walls are more commonly used. Anti-corrosion technology is a process that covers the outer or inner walls of steel pipes with anti-corrosion coatings to protect the pipe itself. It can process various pipes such as straight seam steel pipes and spiral steel pipes. In order to prevent explosions, casualties, property losses and other accidents caused when transporting flammable and toxic fluids, the spiral steel pipe factory adopts corresponding process standards to continuously meet important performance operations and ensure quality and safety in the market during the detection and measurement process. used in.
Anti-corrosion steel pipes generally consist of a layer structure

The quality of pre-treatment has a great influence on the performance of the coating. In the actual coating process, there are many examples of failure to achieve the expected anti-corrosion effect due to poor pre-treatment. In particular, many anti-corrosion coatings with excellent performance can form normal coatings and achieve the expected anti-corrosion protection only by strictly following their respective requirements.
The steel base material must be rust removed, degreased, and phosphated.
The thickness of the anti-corrosion coating must exceed its critical thickness in order to exert a protective effect, generally ranging from mm to mm.
If the primer is left for too long before the topcoat is applied, it will be difficult to adhere and affect the overall protective effect.
Epoxy powder has always been applied using electrostatic spraying process. Because the epoxy powder dipping process is plagued by adhesion problems, epoxy powder dipping has never been widely used. In recent years, with the successful development of Sanye's special phosphating solution for epoxy powder dipping, the adhesion problem of the epoxy powder dipping process has been overcome for the first time, and the emerging process of epoxy powder dipping has begun to be promoted.
Epoxy powder is a thermosetting, non-toxic coating that forms a high molecular weight cross-linked structural coating after curing. It has excellent chemical anti-corrosion properties and high mechanical properties, especially the best wear resistance and adhesion. The coating is 10% solid, solvent-free, and pollution-free, with a powder utilization rate of more than 10%. It is a high-quality anti-corrosion coating for buried steel pipelines.

Adhesive bonding (bonding, bonding, gluing, gluing) refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects together with adhesive, with stress distribution Continuous, light weight, or sealed, most process temperatures are low. Gluing is particularly suitable for connecting different materials, different thicknesses, ultra-thin specifications and complex components. Glue has developed the fastest in recent generations, has a wide range of application industries, and has a significant impact on the progress of high-tech science and technology and the improvement of people's daily lives. Therefore, it is very important to research, develop and produce various types of adhesives.
