Stainless steel elbows are common fittings in piping systems and are widely used in many industrial fields. This article will introduce the manufacturing method of stainless steel elbow.

The manufacturing method of stainless steel elbow mainly includes cold state elbow, hot state elbow, three-dimensional elbow, four-dimensional elbow and many other ways. The following will be introduced in detail:

First, the cold state bend

Cold bending refers to the use of elbow molds to bend stainless steel pipe into the desired angle and radius. This method can maintain the physical and chemical properties of stainless steel pipe, will not affect the performance of stainless steel. In addition, the elbow manufactured by this method has excellent quality and more accurate angle.

The specific production process is: the selection of suitable steel pipe and elbow mold, the steel pipe through the elbow mold bent into a predetermined arc, and then the arc and bending angle inspection, if not meet the requirements continue to cold bending until it meets the requirements. In the entire cold bending process requires attention to the need to control the heating temperature of the elbow and bending angle.

Second, the hot state bend

Hot state bending refers to the stainless steel pipe in the case of heating through the elbow mold bending into the required angle and radius. This method can make the tube easily deformed to achieve a better bending effect. However, the characteristics of the tube, surface finish will change during the hot state bending process, so it cannot be used directly for the transmission of liquids or gases.

The specific production process is: first choose a suitable steel pipe and elbow mold, the steel pipe will be properly heated, and then put into the elbow mold for bending. In the operation, the heating temperature and bending angle need to be controlled to ensure the quality of the stainless steel elbow.

Third, three-dimensional bending

Three-dimensional bending refers to the bending of stainless steel pipe into an elbow with three-dimensional bending. The method is mainly used in specific areas, such as piping systems that need to fit the special shape of the part, or need to be installed in areas with small angles.

The specific production process is: first confirm the bending radius of the stainless steel pipe and the angle of the elbow, and then put the steel pipe into the elbow mold for bending and size inspection.

Fourth, four-dimensional bend

Four-dimensional bend refers to the bending of stainless steel pipe into a special function pipe fitting four-dimensional space bending. This pipe fitting can fit the shape of the space in addition to the direct connection of special equipment, with good sealing performance and stability performance.

The specific production process is: first select the stainless steel pipe, and determine its bending radius and angle, and then put it into the elbow mold for bending, for size inspection.

In short, the above is the manufacturing method of stainless steel elbow, regardless of which method is used, the production process needs to focus on quality control to ensure that the production of products meet the standards.
