Use of heat preservation elbow and hot pressing elbow: Connect two pipes with the same or different nominal diameter to make the pipe bend at a certain angle.
Classification of heat preservation elbows and hot pressing elbows:
1. Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon lapping, ppc, etc.
2. The production methods can be divided into push, press, forge, casting and so on.
3. According to the production process can be divided into: welding elbow, stamping elbow, casting elbow.
4. The manufacturing standard can be divided into national standard, electric standard, water mark, American Standard, German standard, Japanese standard and Russian standard.
In piping system, carbon steel butt welded elbow is the pipe that changes the direction of pipeline.
According to the angle, there are 45 degrees and 90 degrees 180 degrees which are most commonly used, and other abnormal angle stainless steel butt welded elbows such as 60 degrees are also included according to the needs of the project.
Elbows are made of cast iron, stainless steel, alloy steel, calcinable cast iron, carbon steel, non-ferrous metals and plastics.
Connection with pipes in the following ways: direct welding (the most common way) carbon steel flange connection, thread connection and socket connection, etc.
