  Materials and advantages of ASTM A182 butt welding flange

  ASTM A182 butt welding flange is a flange pipe with a neck and a round steel pipe connection, which is connected to the pipe port by butt welding. It is a disc-shaped part, which is most common in pipeline engineering. Flanges are used in pairs. A sealing gasket is added between the two flanges and then fastened with bolts. Flanges of different pressures have different thicknesses and use different bolts. This flange has the characteristics of no variability, good sealing function, moderate rigidity and ductility.

  What is ASTM A105 Flange?

  ASTM A105 flange is a pipe fitting made from forged carbon steel. It is mainly used in piping systems operating under high pressure and at either ambient or elevated temperatures. This flange is widely used in industries such as oil and gas, power generation, petrochemicals, and steam systems.The ASTM A105 standard specifies the chemical composition, mechanical properties, and dimensional requirements of this product, ensuring its strength, ductility, and durability in demanding environments. While there are other flange standards like ASTM A350 for low-temperature use, ASTM A105 flanges are popular for their versatility and reliability.、

  How to Clean and Maintain Stainless Steel Rectangular Tubes ?

  The use of stainless steel rectangular tubes has become more widespread with the development of the economy. People are closely related to stainless steel rectangular tubes in their daily lives, but many people do not know much about the performance of stainless steel rectangular tubes, and know even less about the maintenance of stainless steel rectangular tubes. Many people think that stainless steel rectangular tubes will never rust. In fact, stainless steel rectangular tubes have good corrosion resistance. The reason is that a passivation film is formed on the surface, and it exists in the form of a more stable oxide in nature. In other words, although the degree of oxidation of stainless steel rectangular tubes varies according to different use conditions, they are eventually oxidized. This phenomenon is usually called corrosion.

  What does DN and De mean in steel pipe?

  People always have questions about the DN of steel pipe, so today we will take some time to understand DN.DN is a common term that indicates the nominal diameter of a pipe. DN stands for "Diamètre Nominal", which is a French term that means "nominal diameter". The nominal diameter is the size of the inside diameter of the pipe, generally expressed in millimeters.Steel pipes come in a variety of DN sizes, each with its own specific purpose. Typically, the DN size of steel pipes ranges from DN15 to DN1200. Here are some of the most common steel pipe DN sizes and their corresponding nominal diameters in millimeters:

  Production Technology of Cold-drawn Precision Seamless Steel Pipe

  Cold-drawn precision seamless steel pipes, with their no oxide layer on the inner and outer walls, excellent high-pressure bearing capacity, high precision and high finish, and no cracks during cold bending, expansion and flattening, have become an ideal choice for mechanical structures, hydraulic equipment, and automotive and motorcycle pneumatic or hydraulic components, such as cylinders or oil cylinders. Its production process goes through multiple links such as hot-rolled rough tubes, rough tube inspection and grinding, pickling and re-inspection, cold drawing, straightening, pickling and lubrication, fine drawing, and finished product pre-treatment. Each link is strictly controlled to ensure product quality.

  How to choose the right drill pipe?

  When it comes to how to choose a drill rod, people in the industry know best. No matter what you choose, you must first consider suitability, because the drill rod is used to match the drilling rig. If the drill rod you choose cannot match the drilling rig, no matter how good the drill rod is, it will be idle. So, how do you view the matching of drill rods and drilling rigs? Some friends think that as long as the drill rod and the drilling rig can be connected, it can be used, while others think that there is a certain rule between the two. In fact, these are just amateur ideas and lack basis.

  Production process and steps of stainless steel seamless pipes

  Generally, seamless steel pipes are made of high-quality carbon steels such as 10, 20, 30, 35, 45, low-alloy structural steels such as 16Mn, 5MnV, or alloy steels such as 40Cr, 30CrMnSi, 45Mn2, 40MnB, etc., which are hot-rolled or cold-rolled. Seamless pipes made of low-carbon steels such as 10 and 20 are mainly used for fluid delivery pipelines. Seamless pipes made of medium-carbon steels such as 45 and 40Cr are used to manufacture mechanical parts, such as stress-bearing parts of automobiles and tractors. Generally, seamless steel pipes must ensure strength and flattening tests. Hot-rolled steel pipes are delivered in hot-rolled or heat-treated states; cold-rolled steel pipes are delivered in hot-rolled or heat-treated states.
