Detailed classification of 45 degree stainless steel elbow
Stainless steel 45° elbow can be said to be the most common type of stainless steel pipe fittings and is widely used in chemical, pharmaceutical, food, papermaking, aviation, aerospace, petroleum, electric power and other fields.
Stainless steel 45° elbow has many functions such as turning, connecting, controlling flow, reducing pipeline stress, etc.
It is an indispensable component of the pipeline system.
Divided by material

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, aluminum alloy, aluminum alloy, PPR, RFPP (reinforced magnesium), etc.
Divided by production method
Pushing, pressing, forging, casting, etc.
Divided by manufacturing standards
It can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
Divided according to its radius of curvature
It can be divided into long radius elbow and short radius elbow.
A long-radius elbow means that its radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D; a short-radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D. (D is the elbow diameter, R is the radius of curvature).
According to pressure level
There are about seventeen kinds, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS ;The most commonly used ones are STD and XS.
According to different shapes and uses
Groove elbow, ferrule elbow, double bearing elbow, flange elbow, reducing elbow, dead seat elbow, internal and external tooth elbow, stamping elbow, push elbow, socket elbow , butt welding elbow, inner wire elbow, etc.
