What are the advantages of carbon steel pipe fittings? Carbon steel pipe fittings are a new type of seamless steel pipe connection fittings, also known as clamp connections, which have many advantages. The design standards for automatic sprinkler systems and automatic fire extinguishing systems clearly state that the connection of system software pipelines should use trench joints, threaded joints and loose flanges. In the software, pipes with a diameter of 100mm or more should be connected using flanged or trench connectors.

The interface mode of carbon steel pipe fittings has distinct soft characteristics, which makes the pipeline have anti-vibration and anti-collapse working ability. Compared with electric welding and loose flange, the reliability of the pipeline system software is improved, and it is more adaptable to temperature changes, so as to maintain various valves of the pipeline and reduce the damage to the parts caused by the ground stress of the pipeline. Application of plastic pipe connection technology. It makes the complex pipe connection process easier and more convenient. A big step forward in plumbing technology. The hot simmering elbow is a kind of galvanized steel pipe elbow which adopts the pressing process. The manufacturing specifications of hot elbow can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc. Hot elbows are used in areas where pipes need to change direction, so they are widely used, especially in chemical plants, civil engineering, engineering construction, industrial production and other industries.

Classification of raw materials for carbon steel pipe fittings: Carbon steel can be divided into three types according to its use: carbon structural steel, carbon tool steel, and free-cutting structural steel. Carbon structural steel can be divided into building structural steel and mechanism structural steel. Carbon steel can be divided into low carbon steel (ωC≤0.25%), medium carbon steel (ωC 0.25%-0.6%) and high carbon steel (ωC > 0.6%) according to carbon content. Carbon steel can be divided according to phosphorus and sulfur content It is ordinary carbon steel (high phosphorus and sulfur content).

Good carbon steel (lower phosphorus and sulfur content) and good steel (lower phosphorus and sulfur content) generally the higher the carbon content in carbon steel, the higher the hardness and strength, but the lower the plasticity. Carbon steel pipe fittings are classified by carbon content: by mass percentage of carbon: low carbon steel (C: ≤ 0.25%), medium carbon steel (C: 0.25% ≤ C ≤ 0.6%) and high carbon steel (C: > 0.6% ). The higher the carbon content, the higher the hardness and strength, but the lower the plasticity.

According to the quality of steel (mainly the content of sulfur and phosphorus as impurities): usually carbon steel (S≤0.055%, P≤0.045%), good carbon steel (S≤0.040%, P≤0.040%) and good of carbon steel (S≤0.030%, P≤0.035%). Disposal: Carbon Structural Steel: Mainly used for ships, building components, bridges, machine parts, etc. Carbon tool steel: mainly used for tools, molds, measuring tools, etc. Carbon steel pipe fittings are classified according to the brand and use of carbon steel.
