Short radius elbow refers to the radius of curvature is equal to the diameter of the pipe bend, is often said that 1 times. D mean to elbow diameter.
Long radius is the most commonly used, generally the default also long radius, high pressure or high velocity it USES long radius, if it is solid conveying pipelines is demanding the larger the radius of the elbow.
Short radius is generally used in low pressure fluid or bend with limit of the installation place. If there are no restrictions or specified in the contract without first choose long radius elbow.
Using range: wastewater treatment, chemical, thermal, pharmaceutical, aerospace, electric power, papermaking, etc.
