A flange made of carbon steel is called a carbon steel flange, which is a connection device for two large-diameter pipes. It usually has two flanges plus several fastening bolts. A carbon steel flange is an essential component made from high-quality carbon steel.

Known for its excellent plasticity and reliable performance, low-carbon steel is also recognized for its strength and durability. After adding an appropriate amount of carbon, it will become hard, the plasticity will decrease, and the strength will increase. Flange connections may need to withstand very high tensile, compressive, torsional, and shear strengths. ASTM A106 GRADE B carbon steel flanges are a good choice.

Advantage

The mechanical properties of ASTM A106 Grade B carbon steel flange make it a versatile and reliable component in various applications. With high tensile strength and yield strength, it can effectively handle high pressure and demanding conditions, making it a crucial choice for complex pipeline systems.In addition, ASTM A106 GRADE B carbon steel flange also has good corrosion resistance, is not easy to rust and be corroded by chemicals, and can be used for a long time in various corrosive environments. These properties make ASTM A106 GRADE B carbon steel flange an ideal pipeline material that can meet the use requirements in various harsh environments.

Application Of ASTM A106 GRADE B Carbon Steel Flange

ASTM A106 GRADE B carbon steel flange has a wide range of applications. In petrochemicals, it is used to transport media such as oil and natural gas. It can withstand the influence of high pressure and corrosive environments to ensure the safety and stability of the transportation process.

In the field of electricity, it is used to transport high-temperature and high-pressure steam and water. It can withstand the harsh environment of high temperatures and high pressure to ensure the regular operation of power equipment. In addition, ASTM A106 GRADE B carbon steel flanges are also widely used in infrastructure construction such as bridges and highways. Its excellent mechanical properties and corrosion resistance can meet long-term use requirements.

In addition to the above fields, ASTM A106 GRADE B carbon steel flanges have been widely used in chemical, pharmaceutical, food, and other industries. In these fields, steel pipes need to withstand the erosion of various substances, and the corrosion resistance of ASTM A106 GRADE B carbon steel flanges enables them to be competent for this task. At the same time, the smooth inner wall and low friction of the steel pipe also contribute to the smooth transportation of fluids to meet production needs.

In general, ASTM A106B American Standard seamless steel pipe has excellent mechanical properties and corrosion resistance. Its wide range of applications proves its important position in various industrial fields.As advancements in science, technology, and industry persist in the coming years, the utilization of ASTM A106 Grade B carbon steel flanges is expected to expand into various sectors. This expansion will increase efficiencies and advantages in human production processes and daily life.

Carbon steel flanges have poor corrosion resistance compared with stainless steel flanges, but they also have good sealing performance and flexibility. They will not affect each other during work. You only need to open a steel pipe. This special feature allows carbon steel flanges to reduce certain losses caused by sudden disasters to a lower degree during use, which is more suitable for pipeline maintenance work.

Production Method

Carbon steel flanges are manufactured and produced by different methods and processes in actual production and development. Forging method, roller method, rolling method, and bulging method are the four common production methods of carbon steel flanges.

Using a forging press to punch out the end or part of the pipe to expand the outer diameter of the flange is the forging method. Torsion type, connecting rod type, and roller type are all common commonly used forging machines; the outer periphery of the core check valve placed in the pipe is pushed with a roller, and the roller method is used for round edge processing.

The roller method usually does not require a mandrel and is suitable for the inner circular edge of thick-walled pipes; one is to put rubber into the pipe and compress it with a punch on the top, and the other is hydraulic bulging, the middle of the pipe is filled with liquid, and then the liquid is pressurized to bulge the pipe into the desired shape. These two are bulging methods.

Precautions During Production

The carbon steel flange is welded by two clamping base plates with an angle of 90°, two flange support plates, two vertical plates, and four reinforcing rib plates. To ensure the rigidity of the equipment, the weld of the connecting plate should be opened so that the groove is welded through and the weld angle is 20-30mm high; the corresponding bolt holes are drilled on the flange support plate, and there is a gap between the back of the small end flange and the support plate to fit the small manual jack.

A notch is opened on the flange support plate along the direction of the vertical plate so that the elbow can be installed in the tool; when the tool is clamped on the workbench, the flange plane to be processed should be concentric and parallel to the workbench of the vertical lathe, and the tool should be able to change the clamping position to ensure that the flanges at both ends of the elbow can be processed on one tool, which is to reduce the number of tools. At the same time, the tool needs to have sufficient rigidity otherwise it will seriously affect the processing quality of the flange sealing ring groove.
