1. Zinc coating thickness: The thickness of the zinc coating on the surface of the seamless steel pipe shall meet the requirements specified in the relevant standards, such as GB/T 24186-2009《Seamless Steel Pipe for Fluid Transportation》. The general requirement is that the minimum zinc coating thic

1. Steel grade: Higher-quality steel grades have better wear resistance properties due to their higher carbon content and other alloying elements.2. Surface treatment: Seamless steel pipes can be surface treated to enhance their wear resistance, such as phosphating, chromating, or coating with wear-

Plastic-coated steel pipes not only have the advantages of steel pipes such as high strength, easy connection, and resistance to water flow impact, but also overcome the shortcomings of steel pipes that are prone to corrosion, pollution, and scaling when exposed to water, as well as the low strength

Usually, we use epoxy coal pitch paint. If the requirements are high, you can use 3 oils and 2 cloths. 3 layers of paint and two layers of fiberglass cloth, staggered application. If required, generally use epoxy coal pitch primer and topcoat, each applied twice. Simple and convenient, this is gener

Choosing the right square pipe for your project requires considering a variety of factors to ensure it meets the necessary requirements for strength, durability, size and materials. The following step-by-step guide can help you choose the right square tube:1. Determine the application:Determine the

Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle.Angle steel, like mild steel pipe, is a carbon structural steel for construction.. It is a simple cross-section section steel and is mainly used for metal components and frames

Welded pipes are round pipes welded by steel plates, which are divided into high-frequency electric resistance welded pipes (ERW pipes), straight seam arc welded pipes (LSAW), and spiral welded pipes.Industrial TV internal inspection equipment: inspect the appearance quality of internal welding seam

IntroductionSeamless steel tube for structure purposes(GB/T8162-1999) is a seamless steel tube for general structure and mechanical structure.GB/T8162-- National Standard of ChinaASTM A53-- American Society of Materials and Testing StandardsASME SA53 -- American Code for Boilers and Pressure Vessels

According to the basic principle and process characteristics of nitriding treatment of seamless steel pipes , the process parameters affected by it mainly include nitriding temperature, nitriding time and ammonia decomposition rate.1. Nitriding temperatureWhen the nitriding temperature is 500 °C, th
