What is the function of the elbow

What is the function of the elbow: according to the different process of the elbow to choose different bending radius, in general, or choose  1,5D special case and use 5D and 10D elbow, the use of 1D elbow: there is no special pressure reduction requirements, there is no special fluid flow and special requirements for the use of 1D elbow.The 1D elbow is used more often in overcoat.The 1.5D elbow is used in the pipe to match the 1D elbow of the outer pipe, so that the inner pipe can be inserted into the pipe smoothly and the construction difficulty is reduced.A 1D elbow may be used to reduce pipe vibration.Using a 1D elbow increases the rigidity of the entire pipe, as with a 1.5D elbow.Reduce pipe stress and use long radius elbows to increase pipe flexibility.In the design process of petroleum and chemical pipelines, we also use 3D and 4D elbows instead of pipeline compensators.To reduce pipe pressure reduction, 1D elbow and 1.5D elbow have different equivalent length values in the process of pressure calculation, but the difference is not large. However, if the number of elbows in the whole pipe system is large, there is still some adjustment effect to reduce the fluid power on the pipe.The larger the radius of curvature of the elbow, the less dynamic load the fluid will exert on the pipe system.

Elbows are divided into long radius elbows and short radius elbows, two commonly used elbow fittings.Elbow material is divided into: carbon steel elbow, alloy steel elbow, stainless steel elbow and other materials.Elbow is divided into butt welding elbow, straight seam elbow, seamless elbow and so on.

The above is a brief introduction of the functions of the elbow, as well as the shape of the elbow pipe and the material of the elbow pipe and so on.If you need elbow fittings, our company is willing to serve you.
