Introduction to elbow

In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45 ° and 90 ° 180 °, and other abnormal angle elbows such as 60 ° are also included according to the needs of the project. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The connection methods with pipes include: direct welding (the most commonly used method) flange connection, hot-melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

Development trend of duplex stainless steel

LDX 2101 steel has been industrially trial produced and continuously cast after refining in AOD / clu furnace to produce long casting embryo and plate embryo, but it has not been widely popularized and applied at present. In view of its good comprehensive performance and wide potential range of applications, it is especially promising to be used as structural parts. For example, it can replace 2205 duplex stainless steel as bridge structure, and can also be used as reinforcement in concrete to solve the corrosion problem of materials in chloride ion polluted environment. In addition, It can also replace 304 and 316 steel to make containers, towers, hot water storage tanks and heaters.
