PVC 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, calcinable cast iron, carbon steel, non-ferrous metals and plastics. Connection 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.

PVC pipe elbows have many different specifications, and the size of elbows with different angles is also very different. The elbow size of PVC drain pipe is 450 * 450 pix in general, and the larger elbow size is 630 * 500 pix, of course, the specific problems need specific analysis. The size of 90 degree elbow is usually calculated according to the known pipe diameter, and the bending radius is usually 1.5 times the diameter. According to the different models, 90 degree elbow sizes are different, and its length and radius are also different.
In addition, if you have not used PVC pipes before, or are unfamiliar with the dimensions of PVC pipes, we strongly recommend that you review the following three important details about the size of PVC pipes:
1.The outer diameter is not the size of the PVC pipe.
2.PVC plan is very important
3.Some pipes are not compatible
You should always use the inside diameter of the tube to determine the size of your PVC tube. If you measure the outside diameter of a PVC pipe and order it based on this measurement, you will almost always receive a larger PVC size than expected. Do not order PVC products based on the outside diameter.
The PVC Schedule (abbreviated as SCH or Sch.) is the thickness of the PVC pipe wall. The most common schedule is 40, but Schedule 80 PVC can also be used. As the schedule becomes larger and larger, the pipe wall becomes thicker from the outside, so the inner hole (hole) of the pipe becomes smaller.
In order to get the correct PVC size guide, carefully read the markings on the pipe and measure the physical dimensions of the pipe. Compare with other objects if necessary.
Not all types of pipes are suitable for PVC fittings. For example, the outer diameter of steel pipes and pipes is the same size as the corresponding PVC pipe and is dimensionally compatible, but it is not recommended for use with PVC fittings and fittings because it is not possible to connect the steel pipe to Plastic PVC joints. In most cases, the steel pipe can easily slip out of the fitting, causing the structure to loosen or possibly collapse.
