Carbon steel elbow manufacturer introduces the production process

The basic introduction of carbon steel elbow: carbon steel seamless elbow is resistant to air, steam, water and other weak erosion medium and acid, alkali and other chemical erosion medium erosion of steel. And the butt welding of rear axle housing, all kinds of connecting rod, pull rod butt welding, and special parts of the butt welding. New wear-resistant carbon steel elbow is a combination of ceramics and metal to form a composite pipe, carbon steel elbow combined with alumina high hardness, good chemical properties and the first will not have quality assurance.

Improve the corrosion resistance of carbon steel elbow in reducing medium, especially the local corrosion resistance of chloride. Improve the strength and tempering stability of carbon steel elbow. The study shows that the corrosion resistance of carbon steel elbow in reducing medium can be improved, and the composite action of Mo and Cr can improve the passivation and re passivation ability of carbon steel elbow, improve the stability of passivation film, so that stainless steel has good corrosion resistance.

Carbon steel elbow is a metal pipe that changes the direction of the carbon steel pipe. The connection mode is threaded and welded. According to the Angle, there are three kinds of 45° and 90°180° commonly used, in addition according to the engineering needs also include 60° and other abnormal Angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics, etc. The ways to connect the pipe are: direct welding (common way) flange connection, hot melt connection, electric melt connection, thread connection and socket type connection. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow and so on. Other names: 90 degree bend, right Angle bend, love bend and so on.

Forging method: the end of the pipe or part of the forging machine to stretch, so that the outer diameter is reduced, commonly used type forging machine has rotary, connecting rod type, roller type.

Rolling method: generally without mandrel, it is suitable for the inner circular edge of thick wall pipe. The core is placed in the tube, and the roller is used to push and press the outer edge.

Stamping: expansion of tube ends to desired size and shape with tapered cores in a punch press.
