Carbon steel pipe fittings, as an indispensable part of the modern industrial field, its special performance and wide application field make it a material in many industries. Carbon steel pipe fittings are currently the most widely used pipe fittings. They have different shapes and sizes, including elbows, tees, crosses, flanges and caps. Carbon steel pipe fittings have many advantages, such as pressure resistance, corrosion resistance and strong reliability, so they are widely used in many industries. Below, we will discuss the main characteristics of carbon steel pipe fittings in detail.
What are the types of carbon steel pipe fittings?
The main products include
carbon steel elbows, carbon steel flanges,
carbon steel tees, carbon steel crosses, carbon steel reducers (large and small heads), carbon steel heads (pipe caps), etc. The main implementation standards include national standards, American standards, Japanese standards, etc. among which the Chinese standards include the Ministry of Chemical Industry standards, Sinopec pipe fittings standards, and power pipe fittings standards.
Classification by shape
Elbow: used to adjust the direction of the pipeline.
Tee: used to connect three pipes, making the flow connection more complicated
Cross: used to connect four pipes, making the flow connection more complicated.
Flange: used to connect the part between two pipes, usually need to be fastened with bolts,
Pipe cap: used to close one end of the pipe.
Classification by processing method
Cold drawing: using processing machines to shape the pipe, the surface finish after processing is high and will not produce
Forging: The steel is stamped and extruded to form the required shape, which is more refined than the cold drawing process.
Welding: Using welding machines to weld the pipe into shape, no deformation will occur after processing.
Standards for carbon steel elbows
Carbon steel elbows can be divided into long radius elbows and short radius elbows according to their radius of curvature. Long radius elbows refer to elbows whose radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D. Short radius elbows refer to elbows whose radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D. (D is the diameter of the elbow, R is the radius of curvature. D can also be expressed in times.)
If divided by pressure level, there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are commonly used. According to the angle of the elbow, there are 45° elbows, 90° elbows and 180° elbows. The implementation standards are GB/T12459-2005, GB/T13401-2005, GB/T10752-1995, HG/T21635-1987, D-GD0219, etc.
The manufacturing process of carbon steel pipe fittings
The connection process of carbon steel pipe fittings is very unique. Nowadays, pipe fitting technology is very developed. Some connections can be completed very simply. Some pipes can be connected together by making a groove on the surface of the pipe. It will not cause any damage to the inner wall of the pipe. This is incomparable to traditional welding technology. Let's take a look at some knowledge about carbon steel pipe fittings. Carbon steel pipe fittings have high strength. This is mainly due to its carbon steel material, which enables carbon steel pipe fittings to withstand huge pressure and weight. Under high pressure and heavy load conditions, carbon steel pipe fittings can still maintain stable performance, providing reliable support for various industrial applications. First, weld a circular shell with an irregular cross-section, or a fan-shaped shell with airtight sides, fill it with pressure medium, and then apply internal pressure to it to make its shape circular, becoming a round shell, and then cut them into 90-degree or 60-degree elbows, or elbows of other specifications according to your needs. Many large elbows can be made in this way. This method is very practical.
Advantages of Carbon Steel Pipe Fittings
1. Carbon steel pipe fittings are very convenient to cut, the precision is easy to ensure, and they are well welded together. It does not require pipe blanks, does not need to purchase equipment, and saves money on making molds. You can make many pipe fittings of different sizes, and their wall diameters are not thick, so its production cycle is short and the production cost is very low. It does not require special equipment and can make many large elbows, which is efficient, time-saving and money-saving.
2. Carbon steel pipe fittings are not easy to rust. Compared with other pipe fittings, it is not easy to rust because its carbon content is not very high, and its shape is very beautiful, the line is smooth, the organization is very dense, and the mechanical properties are very high. Carbon steel pipe fittings can withstand great pressure, it can connect pipes together, and its connection is also very simple and easy to operate. In the construction of pipelines, the connection of carbon steel pipe fittings is very extensive. In large construction sites, connected carbon steel pipe fittings can be seen everywhere.
3. The interface mode of carbon steel pipe fittings has distinct soft characteristics, which makes the pipeline have the ability to resist vibration and collapse. Compared with electric welding and loose flanges, it improves the reliability of pipeline system software and is more adaptable to temperature changes, thereby maintaining various valves of the pipeline and reducing the damage of pipeline ground stress to parts. The application of plastic pipe fittings connection technology. Make the complex pipeline connection process simpler and more convenient. It makes the pipeline connection technology a big step forward. The hot elbow is a galvanized steel pipe elbow using a pressing process. The manufacturing specifications of hot elbows can be divided into national standards, electric standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc. Hot elbows are used in areas where pipelines need to change direction, so they are widely used, especially in chemical plants, civil engineering, engineering construction, industrial production and other industries.
The above are some classifications and advantages of
carbon steel pipe fittings. In summary, carbon steel pipe fittings have become an indispensable part of industrial pipeline systems due to their high strength, easy processing and good corrosion resistance. The simplicity of its manufacturing process and the superiority of its materials make carbon steel pipe fittings play an important role in various application scenarios.
