Elbows are used to connect two pipes with the same nominal diameter in a pipe system. The elbow is made of stainless steel, alloy steel and carbon steel. According to the production process, it can be divided into welding elbow, stamping elbow, etc.; the nominal pressure of the elbow is 1-1.6Mpa. Elbows are widely used in infrastructure projects such as chemical engineering, construction, water supply, drainage, petroleum, pipelines, and electricity.
According to the viewpoint, there are three most commonly used ones: 45°, 90°and 180°. Others include 60°and other abnormal viewpoint elbows according to engineering requirements. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.
The methods of connection with the pipe include: direct welding (the most common method) flange connection, hot melt connection, electrofusion connection, thread connection and socket type connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow. Other titles: 90 degree elbow, right angle bend, etc.
Elbows are commonly used fittings in plumbing installations. They are used to connect pipe bends and to change the direction of pipes. Other titles: 90° elbow, right angle bend, love bend, stamping elbow, limit elbow, machine elbow, welded elbow number. Use: To connect two pipes with the same or different nominal diameters, so that the pipeline can be turned at 90°, 45°, 180° and various degrees.
A tortuous radius less than or equal to 1.5 times the pipe diameter is attributed to the elbow, and more than 1.5 times the pipe diameter is attributed to the elbow. Skill requirements, because most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, leaving a certain point of view, with a certain edge. This requirement is also relatively strict. How thick the edge is and how much the point of view is The error scale has rules. The appearance quality and mechanical properties are basically the same as the tube.
For the convenience of welding, the steel grade of the pipe fitting and the pipe being connected is the same. That is, all the pipe fittings must be treated on the outside, and the oxide scale on the inside and on the outside must be sprayed off by shot blasting, and then coated with anticorrosive paint. This is for export demand, and also for facilitating transportation and avoiding rust and oxidation. All these operations must be done.
