Reducing elbow making matters

Reducing elbow is a pipe connection, its role is to connect two different diameters of the pipe, and change the flow of the pipe. In industrial production, reducing elbow is widely used in petroleum, chemical industry, electric power, metallurgy, paper and other fields.

Making method of reducing elbow

The reducing elbow is usually made of carbon steel, stainless steel, alloy steel, etc. In the selection of materials, it is necessary to consider the use of the pipeline environment, the nature of the medium, temperature and pressure and other factors. At the same time, it is also necessary to prepare the drawings and tools of the elbow, such as cutting machines, welding machines, grinding machines, etc.

The production process of reducing elbow is the template of elbow that needs to be combined with the drawing size of elbow. Formwork requires accurate measurement of pipe diameter, length and elbow orientation.

Then, according to these data, CAD software is applied to describe the three-dimensional modeling of the elbow and convert it into a two-dimensional drawing. Finally, according to the drawing size of the bend template.

The pipeline is divided according to the requirements of the template. During the division, attention should be paid to maintaining the tidiness and flatness of the pipeline to ensure the stability and quality of the elbow

Shape the two ends of the pipe to fit the bend. In processing, it is necessary to use equipment such as grinding machines to adjust the two ends of the pipe to ensure that it is closely connected to the elbow.

Shape the middle section of the pipe into a bend shape. In addition, a pipe bender is needed to bend the pipe to the desired Angle and radius. After bending, it is necessary to use equipment such as grinding machines to adjust the inner and outer surfaces of the elbows to ensure that they are smooth and neat.

Weld both sides and the middle section of the elbow. When welding, the welding machine is needed to fix the two ends and the middle section of the pipe.

When welding, it is necessary to pay attention to controlling the welding temperature and time to ensure the quality of the weld. After production, the elbow needs to be tested. The inspection mainly includes the size, appearance and weld quality of the elbow. Only the elbows that have passed the inspection can be delivered for use

Reducing elbow precautions

When making reducing elbows, it is also necessary to pay attention to maintaining the tidiness and flatness of the pipeline to ensure the stability and quality of the elbow, and it is necessary to pay attention to controlling the welding temperature and time to ensure the quality of the weld

It is necessary to pay attention to the protection of the environment and safety, avoid pollutants such as waste gas and waste water, and comply with relevant standards and specifications to ensure the quality and safety of the elbow.
