How to divide these elbows?
Thread Content
Excuse me: What is the difference between hot-pressed elbow, stamped elbow and simmered elbow? What are the processing procedures and appearance?
Indicate in the material list when designing: Material, pipe diameter, bending degree (such as 90 degrees or 45 degrees, etc.), bending radius (1d, 1.5d, etc.), and SCH are enough.
Hot press elbow: After the pipe is evenly heated, it is mechanically bent (large diameter, pipe wall thickness) stamping elbow: Mechanical bending at room temperature (small diameter) Simmering elbow: Partially heated hand-bending
These three types of elbows are mainly divided into processing techniques. As mentioned on the 3rd floor, hot press elbows: After the pipe is evenly heated, it is mechanically bent. It is generally used for large diameter and thick pipe wall. That is, after mechanical bending, the local wall thickness becomes thinner and the elbow is stamped within the allowable range of the standard.: Mechanical bending at room temperature, generally used to simmer elbows in situations where small diameters are easy to bend.: Partially heated hand-bending
