How to choose anti-corrosion steel pipe

Anti-corrosion coated steel pipe, through the anti-corrosion process, is to prevent corrosion or slow down corrosion in the chemical or electrochemical reaction that occurs during the transportation and use of steel pipes. According to our statistics, China's annual economic losses due to pipeline corrosion exceed 280 billion, and global annual pipeline corrosion losses amount to 500 billion. Anti-corrosion coated pipelines can effectively stop and slow down erosion, so the technology is widely used in industry.

Anti-corrosion steel pipes are mainly used in petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields in China. Anti-corrosion steel pipes are divided into the following categories.

How to choose anti-corrosion steel pipe


IPN8710 corrosion

When steel corrosion in more kinds of media, such as acids, alkalis, salts, oxidizers and water vapor, the coating must be chemically inert, acid salt corrosion, the coating should be dense structure, water permeability, adhesion, tough and plump. Such cases are IPN8710 corrosion.

IPN8710 anti-corrosion primer: composed of polyurethane, polyethylene, modified epoxy resin, non-toxic anti-corrosion pigments, additives, etc., room temperature curing to form interpenetrating networks, coating structure is dense, acid, alkali, salt, rust resistance, strong adhesion of water supply pipe wall anti-corrosion primer. IPN8710 anti-corrosion topcoat: composed of epoxy resin, rubber, resin modification, non-toxic anti-corrosion pigments, additives, etc. Excellent chemical resistance, non-toxic, anti-microbial corrosion, anti-corrosion protection of water pipeline wall.

FBE epoxy powder corrosion

FBE epoxy powder anti-corrosion structure: electrostatic spraying epoxy powder coating on the surface of steel parts, film formation. The coating has the advantages of simple coating operation, clean, good coating impact resistance and bending performance, temperature resistance, etc.

2PE/3PE corrosion

2PE/3PE anti-corrosion structure: the surface adopts steel plate and epoxy powder electrostatic spraying adhesive side winding, side winding polyethylene coating, combining the excellent performance of the three, thus significantly improving the overall anti-corrosion quality of the pipeline. Chemical corrosion resistance, cathodic stripping resistance, performance mechanical damage.

Coal tar epoxy anti-corrosion

Coal tar epoxy anti-corrosion structure: made of epoxy resin + coal tar asphalt filler + anti-corrosion coating, coated with glass cloth on the steel surface to strengthen the coating formation, commonly used in the inner wall of the pipeline anti-corrosion. Thickness 0.5 ~ 1.0mm.

High-density polyethylene sheath corrosion

High-density polyethylene sheathing anti-corrosion structure: The outer surface of the pipe is wrapped with high-density polyethylene material, which has high mechanical strength and excellent corrosion resistance, and can protect the steel from damage by external factors during transportation, installation and use.

The manufacture of bracket should add antioxidant, UV stabilizer and carbon black etc.

Easy to age polyethylene casing, such as open storage tarp and other suitable cover, stacking should be away from high temperature fire, anti-corrosion steel pipe made to prohibit exposure to the sun, sudden cold, otherwise polyethylene sheathing tube is prone to cracking, affecting product performance and service life.

Investment Casting vs. Die Casting: Which Is Right for Your Application

图片
    Casting is an ancient manufacturing technique that dates back to the 1890s. Two common casting techniques available today are investment casting and die casting. Although these technologies share the same basic principles, investment casting has specific differences from die casting. Investment casting involves injecting wax into an aluminum mold cavity. The die casting process, on the other hand, forces molten metal under high pressure into the mold cavity. This article will provide an overview of these technologies, including their main advantages. You'll also learn the differences between investment casting and die casting to help you choose the best option for your project. Detailed Comparison: Investment Casting Vs Die Casting work process The  precision custom casting  process begins with making a wax pattern that is used to produce the desired end product. The operator then attaches wax to the base of the sprue and repeatedly dips them into the ceramic mold. After the ce

Best Practices for Applying Cold Lamination Film

图片
  In the ever-evolving landscape of document protection and graphic enhancement, cold lamination has emerged as a versatile and efficient solution. Whether you are safeguarding important documents or enhancing the vibrancy of graphics, applying   cold lamination film   requires finesse and attention to detail. In this comprehensive guide, we unveil the best practices that will elevate your cold lamination process, ensuring a flawless finish that stands the test of time. Before we dive into the best practices, let's establish a foundational understanding of cold lamination. Unlike its hot counterpart, cold lamination utilizes pressure-sensitive adhesives to bond the film to the surface. This makes it an ideal choice for heat-sensitive materials, such as documents and graphics produced with inkjet printers. Selecting the Right Cold Lamination Film The success of your lamination project hinges on choosing the right film. Consider the following factors: 1. Film Thickness Choose a film
