180° carbon steel elbow VS 90° elbow

Today, i will show the most welcome products to you: 180° carbon steel elbow VS 90° elbow. When the two sections of the tube is parallel, the axis is not coincident, using 180° carbon steel elbow, than two 90° elbow less than a weld.
180° carbon steel elbow VS 90° elbow Use Occasion:  
1. When the media in the pipeline need to flow in the opposite direction, and the layout of space is not enough, with 180° carbon steel elbow or U-bend can be resolved;
2. If you use 90° carbon steel elbow, the general middle need a certain short tube, and weld increase, the cost increases but the stress resistance is bigger;  
3. Some of the spray-type serpentine heat exchanger may be used to 180° carbon steel elbow, can also be directly simmering bends, common in the early synthetic ammonia compressed gas heat exchanger.

About two 45 degree elbows pieced together into a 90 degree elbow

Two 45 degree elbows can not be welded into 90 degree elbows for use, because elbows are the concentration of stress on the pipe, expansion and cooling deformation of most of the stress is released at the elbow. In addition, the weld itself should be a weak link, fatigue deformation will soon cause cracking damage, which buried a great hidden danger, so you can not figure out for a while convenient, and ultimately cause huge losses.
About other elbow
Elbow in pipe system, 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 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, malleable iron, carbon steel, non-ferrous metals and plastics. Connecting with the pipe are: direct welding (the most commonly used way) flange connection, hot melt connection, electric melt connection, threaded connection and socket connection. According to the production technology, it can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow and so on. Other names: 90 degrees elbow, right angle bend, love and bend.

180° carbon steel elbow VS 90° elbow
When the pipe needs to turn, we use this part, which is called the elbow. Elbow production materials are divided into many kinds, there are stainless steel materials, there are cast iron materials, of course, there are alloy materials, this part is divided into many angles, different angles of the shape of the parts, now many people are also understanding, the angle of this part is divided into how many kinds? Which of these angles is most commonly used?
180° carbon steel elbow VS 90° elbow
In the building materials market, we can often see distributors in the sales elbow, in fact, this part is divided into many categories, different kinds of parts from different angles, usually, in the building materials market, the more common angle, there are 45 degrees, 60 degrees, 90 degrees and 180 degrees, these degrees are more common parts. But also have other angles of the parts, if people have special needs, can also find this part of the manufacturer of large quantities of custom-made, people can be customized special angle of the parts.
