Production technology and application of reducing elbow

Reducing elbows are usually produced by reducing the diameter. First, cut a V-shaped notch at one end of a finished elbow with the same larger diameter as the reducing elbow, put the elbow into the mold, reduce the diameter of the elbow through the pressure of the press, and the pressure process should be slow to slowly eliminate the internal stress, gradually shrink into a round mouth, and then weld the notch, The finished reducing elbow is shaped by the elbow shaping machine.(Two kinds of production technology and comparison of reducing elbow)

Methods for detecting reducing elbow and pushing elbow:

Use a thickness gauge to detect the wall thickness of outer arc, side arc and inner arc, and use a platform scribing method to detect the radius of curvature, port section diameter and length machining allowance. The pushing speed is increased by 15mm per minute and the radius of curvature is increased by 50mm, that is, the pushing speed is accelerated and the radius of curvature is increased.

Reducing elbow is used in water supply pipeline, steam pipeline, gas pipeline and oil pipeline. The color of reducing elbow is black, with excellent quality, wear resistance and not easy to be damaged. The specification of reducing elbow is 1 / 2-10 inch. The products are widely used in pipeline installation, installation, supporting and other services in petroleum, chemical industry, metallurgy, electric power and other industries.
