  There are many pipe fitting bend used in the bending part of the pipeline, and the direction of the pipeline can be changed by using the pipe fitting bend. There are many kinds of Stainless Steel 90 Degree 10D 304L Large-Caliber Pipe Fitting Bend, such as 45 degree pipe fitting bend and 90 degree pipe fitting bend. The bending radius is about 1.0 times of the outside diameter of the tube, which is called short radius pipe fitting bend, and 1.5 times of the outside diameter of the tube, which is called long radius pipe fitting bend. In the pipeline system layout, it is generally appropriate to use long radius pipe fitting bend connection, short radius pipe fitting bend is usually used in the pipeline installation location is more compact occasions or in order to reduce costs.

  When using short radius pipe fitting bend, the maximum working pressure should not exceed 0.8 times of long radius pipe fitting bend of the same specification. Oblique pipe fitting bends are usually used in large-sized pipes with low pressure, water and similar fluid medium conditions. When the angle of the single section variable direction of the oblique pipe fitting bend is greater than 45, it is better not to be used in poisonous and flammable medium pipelines, or in pipelines subject to vibration, pressure fluctuation and alternating load due to temperature change.
