Elbows are common horizontal pipes in pipeline installation. Used for elbow connections to change the direction of the pipe. How to protect and care for the elbow. Long-term storage of elbows should be observed as planned. The exposed processing appearance must always be cleaned to eliminate dust, and stored cleanly in indoor wind-soaked holes. Partial storage should not be stacked or stored in the open air. Always stick to blunt and ventilated elbows, stickers are clean and tidy, according to the exact storage method. For the device, the elbow can be directly equipped on the line according to the connection procedure, depending on the direction of the device. Generally speaking, the equipment may be in the direction of the line, but it needs to be easy to check. Note that the medium flow of the cutting elbow should be vertical and upward.
In the production process of conventional technology, the lubrication of the elbow can meet the quality requirements of the bending pipe in the manufacture of the elbow, but its disadvantage is the oil-based pipe lubrication product. It is not easy to clean, because you need to take the method to eliminate the direct impact of its serious pollution on the environment. Its washable direct welding feature, which effectively reduces or even allows you to avoid its environmental problems and pay for materials and financial resources in order It can effectively meet the quality requirements of bent pipe products, and it is possible to significantly improve the company's production efficiency and product quality.
In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three commonly used elbows of 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The connection methods with the pipe include: direct welding, flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. 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.
