In a piping system, a bend is a pipe that changes the direction of the pipe.
Purpose: it is a common connection fitting used in pipeline installation, connecting two pipes with the same or different nominal diameter to make the pipe turn at a certain Angle.According to the Angle, there are 45° and 90°180° three most commonly used, in addition according to the engineering needs also include 60° and other abnormal Angle elbow.Pipe connection methods include: direct welding (the most 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.
classification
1. According to the material classification of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PVC, PPR, etc.
2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.
3. According to the manufacturing standard, it can be divided into GB standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.4. According to its radius of curvature, it can be divided into long radius elbow and short radius elbow.Long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is, R=1.5D.Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is elbow diameter, R is radius of curvature).6. According to different shapes and uses, it can be divided into: grooved elbow, card sleeve elbow, double socket elbow, flange elbow, reducing elbow, fixed seat elbow, internal and external tooth elbow, stamping elbow, push elbow, socket elbow, butt welding elbow, inner wire elbow, etc.Punching elbow: DN50R1.5, PN16.DN nominal pass, R1.5 nominal bend rate, that is 1.5 times of nominal diameter, PN pressure grade is 1.6mpa.The specification of steel pipe is DN*3.5 or ф *3.0.DN nominal diameter, ф meter diameter (generally used for seamless steel pipe), suffix digital meter steel pipe wall thickness.If there is no material requirement, default Q235 or 20# steel.
