The advantages of reducing the manufacturing process of elbow pipe are mainly shown in the following aspects: raw materials need the blank of elbow pipe, which can save the cost of mold and obtain the elbow pipe with any caliber. The blank is elbow blank, which is simple in work, easy to ensure accuracy and convenient in assembly and welding. Due to the above two reasons, the manufacturing cycle can be shortened and the production cost can be greatly reduced. Reducing elbow, also known as reducing elbow, is a production process of cutting standard elbow blank into V-shaped elbow and then applying pressure. With the help of the power of conventional or special stamping equipment, the elbow blank is directly deformed by deformation force in the die, so that the product parts with certain shape, size and performance are obtained, and gradually become round under pressure, and a circular shell is formed by welding. Reducing elbow machining is a metal cold deformation machining method. It is one of the main methods of metal plastic working (or pressure working) and also belongs to material forming engineering technology.

Elbows are suitable for all kinds of water quality. There is no need to control water quality except disinfection and sterilization. At the same time, there is no corrosion and excessive seepage, which can keep the water pure and sanitary, prevent secondary pollution and withstand the impact of high water flow up to 30 meters per second. Stainless steel elbow has high connection strength, strong anti-vibration ability, and the connection part is firmly made at one time, thus avoiding the possibility of "loose joint", convenient and fast construction, avoiding on-site welding operation and wire wrapping operation, and having long service life. The field corrosion test data show that the service life of stainless steel elbow can reach 100 years, and the stainless steel elbow hardly needs maintenance. Therefore, it has good cost performance, low operating life cost and remarkable economic benefits.
