Carbon steel elbow is a kind of elbow conveying medium, high-density polyethylene outer tube and polyurethane rigid foam carbon steel layer filled between the elbow and outer tube tightly combined, it is a kind of high-density polyethylene Protecting pipe polyurethane foam plastic prefabricated direct buried carbon steel elbow, only need to put the rust and anti-corrosion elbow in the polyethylene sleeve, inject polyurethane foam in the middle to fully fill the gap between the elbow and the polyethylene sleeve In the later stage, the elbow, casing, and carbon steel layer form a solid whole to achieve the effect of anti-corrosion carbon steel, and the carbon steel elbow is formed.

Most carbon steel elbows are processed by pressure, which will cause plastic deformation of the processed carbon steel elbow. According to the different processing temperature of the elbow, it can be divided into cold processing and hot processing. The main processing method of carbon steel elbow is: semi-continuous rolling mill: including a 1-stand Steckel rolling mill and a 5-stand finishing rolling mill. On the semi-continuous rolling mill, The hot rolling of the pipe fitting in the finishing pass is substantially constant from one end to the other end of the pipe fitting;

The time between passes on the finishing mill is usually less than 3s. The pipe fitting process is characterized by the presence of central segregation in continuous casting thin slabs. Eliminating central segregation in continuous casting thin slabs is a key technical issue to further improve the quality of carbon steel elbow pipe fittings.

In addition, carbon steel elbow is a kind of elbow that can increase the warmth temperature. It is often used in people’s daily life and has been widely accepted and used by people. Carbon steel elbow is widely used in construction, decoration and pipeline laying, which can guarantee The normal flow of the pipeline.

Carbon steel elbows can be used as roofs, doors, windows, curtain walls, interior and exterior wall finishes, railings, etc. in construction. They are widely used in the entrances, entrance halls, and central halls of shopping malls, restaurants and hotels. In the Tonggao Hall and the Four Seasons Hall, they are also frequently selected, because carbon steel elbows are not just a novel architectural decoration method with high appreciation value.

At the same time, because of its mirror reflection effect, it can get the effect of different colors and sceneries in the surrounding environment. At the same time, with the cooperation of lights, it can also form the high light part of the crystal bright hall, which helps to form the center of interest in the space environment in these shared spaces, and embellish and contrast the effect of the space environment.

According to the development of the carbon steel elbow fitting industry, new requirements have been put forward for carbon steel. The industry believes that the carbon steel industry has a large market capacity, but the competition has not diminished. The answer is to increase technological development. For example, the colorful carbon steel craftsmanship of some carbon steel manufacturers has transformed the gleaming carbon steel products into a variety of colors, filled the domestic gap, and reached the level of reliability in the foreign industry. Carbon steel products used in construction and decoration include thin steel plates, pipes, profiles and various profiles and various shapes. The thickness of thin steel plates is less than 2mm. Thin steel plates are mostly thin steel plates to prevent pipelines from cooling and shrinking due to ambient temperature and pushing.

The heating sensor and thermal sensor are combined into a heating combination sensor that reduces preheating and reduction to form a heating combination sensor, which is not only required for the production of large-diameter elbow combined sensors, but also very effective in the production process of stainless steel elbows.
