  • Detailed explanation of pipeline pressure grade classification

    The classification of pipeline pressure levels refers to dividing the pipeline pressure levels into high pressure, medium pressure, low pressure and other levels according to the pressure that the pipeline must bear during work.
  • How long does galvanized steel pipe last?

    Galvanized steel pipe usually means that a layer of zinc is coated on the surface of the steel pipe to prevent it from rusting, thus improving its service life. So, does galvanized steel pipe have a shelf life?
  • Why Are Anti-Corrosion Coated Steel Pipes So Popular?

    The main reason why steel pipes need to be coated with anti-corrosion materials is to prevent corrosion and extend their service life. Corrosion refers to the erosion and damage of metal surfaces by oxygen, water, chemicals, electrochemical reactions and other factors. The following are the reasons why some steel pipes need to be coated with anti-corrosion materials.
  • Anti-corrosion Technology of Steel Casing Pipe

    Pipeline anti-corrosion encompasses measures aimed at retarding or preventing the degradation of pipelines caused by the chemical and electrochemical effects of internal and external media, or the metabolic activities of microorganisms. The primary purpose of pipeline anti-corrosion is to impede corrosion resulting from chemical or electrochemical reactions within pipelines. Two predominant anti-corrosion methods are commonly employed for petroleum steel casing pipes: coating anti-corrosion and electrical protection.
  • Production Process of Butt Welding Elbow

    Butt welding elbows are elbows that undergo a hot forming or forging process, and their primary method of connection is through direct butt welding to the pipe. These elbows are categorized based on their curvature radius, resulting in two main types: long radius butt welding elbows and short radius elbows. Additionally, they are classified according to pressure levels, aligning with approximately seventeen types that adhere to American pipe standards, with STD and XS being the most commonly utilized. Furthermore, based on the elbow angle, variations include 45-degree butt welding elbows, 90-degree butt welding elbows, 180-degree butt welding elbows, and elbows with other angles. In terms of material, butt welding elbows can be further divided into carbon steel elbows, alloy steel elbows, and stainless steel elbows.
  • Flange Processing and Connection

    Flanges play a crucial role in connecting pipes, valves, and other components in a piping system. The processing and connection of flanges involve specific steps and considerations to ensure a reliable and secure connection. Here is an overview of the flange processing and connection process:
  • What Is Stainless Steel Pipe Caps?

    Stainless steel pipe caps are end fittings or closures used to seal the ends of stainless steel pipes. Stainless steel pipe caps are typically designed to fit over the outside of the pipe's end and can be welded, threaded, or clamped in place, depending on the specific requirements of the application. They are available in various sizes, shapes, and materials, allowing them to be customized to suit the specific needs of different industries and projects. Read on to learn more about stainless steel pipe caps.

  • What is the price of 4*6 stainless steel square tube?

      Stainless steel square tube is a kind of square tube material. In fact, it is a steel tube with the same length. The strip steel is processed and rolled. Usually, the strip is unpacked, flattened, crimped, welded to form a round tube, and then rolled into a square tube by a round tube and cut to a desired length. Stainless steel square tubes are mainly divided into two types: seamless and welded. The seamless square tube is formed by extruding a seamless tube. For those who want to buy stainless steel square tubes, it is necessary to know the specific price. So today, Xiaobian will tell you about the market price of 4*6 stainless steel square tube.
  • Detailed analysis of stainless steel price list

      As a material with a wide range of applications, stainless steel has a very high market demand. So what is the current market for stainless steel? Next, Xiaobian will share with you the latest stainless steel price list, I hope you will like it.
  • What are the factors affecting the price of 316l steel pipe?

      The 316L is a model in stainless steel tubing and is currently very valuable in use and market demand. People who often pay attention to the price of stainless steel pipes will find that the price of stainless steel pipes fluctuates greatly, sometimes rising to exaggeration, and sometimes falling to the bottom. Only after we understand the factors affecting the price of stainless steel pipes can we be keenly aware of the fluctuations in the price of stainless steel pipes and respond well in advance. So what is the price of 316L steel pipe?
  • Steel pipe difference: the difference between precision steel pipe and spiral steel pipe

    Precision spiral steel pipe is a kind of high-precision steel pipe after cold drawing or hot rolling. Because the inner and outer walls of precision spiral steel pipe have no oxide layer precision spiral steel pipe, high pressure and no leakage, high precision, high smoothness, no cold deformation, flaring, flattening without cracks, etc., it is mainly used to produce pneumatic or hydraulic components.
