  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.

  Benefits of Stainless Steel Flanges

  In the construction of large-scale pipelines, we can see stainless steel flanges as pipe fittings. Because stainless steel flanges have many excellent characteristics, they have many applications in large-scale pipeline construction. However, because stainless steel flanges are not a common component, many people do not know much about stainless steel flanges. So what are stainless steel flanges like? What are the specific advantages? Let's take a look together!

  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.

  Black Square Tube Production Process

  Black square tube is a commonly used steel pipe material, also known as black rectangular steel pipe or square welded pipe. Its cross-sectional shape is rectangular or square, with high strength and compressive resistance. Black square tube is mainly made by welding process, and common finished product sizes are 30*20mm, 40*20mm, 50*25mm, etc., which can also be customized according to customer needs.

  What are the advantages of seamless steel pipes?

  Seamless steel pipes have excellent properties compared to many steels. Under the same bending and torsional strength, they are lighter than solid steel such as round steel. They are economical steels with a wide range of uses. In order to improve the efficiency of the use of seamless steel pipes, we will focus on their performance. How to choose a suitable seamless steel pipe? Only by making the best use of it can the efficiency of the use of seamless steel pipes be improved. Today, the editor mainly introduces the advantages of seamless steel pipes.

  Pipeline pickling and passivation process and precautions

  Pickling and passivation of stainless steel pipes is a common process used to improve the corrosion resistance and extend the service life of stainless steel pipes. Pickling is a method of using chemical reactions to dissolve rust, oxide films and other products on the surface of the workpiece without affecting the base metal. Passivation is a method of using chemical reactions to form a dense oxide film on the surface of the workpiece. Its purpose is to prevent electrochemical corrosion by establishing an oxide film or oxygen adsorption layer on the surface of the workpiece, thereby improving the corrosion resistance (anti-electrochemical corrosion) of the metal.

  Hollow vs Solid Steel Pipes Full Comparison

  Today we are going to talk about steel pipes. It may sound a bit dry, but don't worry, we will make this topic easy and interesting so that you can understand it clearly. Hollow and solid steel pipes, these two guys are like two friends with different personalities, each with its own advantages and disadvantages. You know, steel pipes are really everywhere in our lives, from construction to transportation, they can be seen everywhere. Just like the rice on the table, although it is inconspicuous, it is an indispensable role. Today, let's take apart the "personalities" of these two steel pipes and see what the difference is in their strength and stiffness.

  ASTM A53 ERW Steel Pipe Specifications Grades and Uses

  ASTM A53 (also known as ASME SA53 pipe) is a carbon steel alloy used as structural steel or low-pressure piping, and is also suitable for general use in steam, water, gas, and air piping. The alloy specifications are established by ASTM International in the ASTM A53 / A53M specification. A53 pipe is available in three types (F, E, S) and two grades (A, B).ASTM A53 ERW steel pipe refers to a carbon steel pipe that conforms to the American Society for Testing and Materials (ASTM) A53 standard and is manufactured using the electric resistance welding (ERW) process. It is a type of steel pipe widely used in conveying media and pressure-bearing structures, such as piping systems for steam, water, gas and air, as well as in the construction and machinery industries.

  How long is the service life of carbon steel pipe?

  Carbon steel pipe is made of steel ingot or solid round steel through perforation into rough pipe, and then hot rolled, cold rolled or cold drawn. Carbon steel pipe plays an important role in my country's steel pipe industry. Carbon steel pipe fittings are made according to your medium and working conditions. No one dares to guarantee that they can be used for ten years or so. If the material is not suitable, even the best alloy may be corroded in 3 months.
