Pipe Bending

Bend is a complete set of bending equipment used for bending, which is divided into two processes: cold bending and hot pushing. Regardless of the type of machinery, equipment, and pipelines, most of them use bent pipes, mainly for oil, gas, infusion, engineering and bridge construction, etc.

Pipe Bending

1. Divided by material:

Carbon steel: ASTM/ASME A234 WPB, WPC

Alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV

Stainless steel: ASTM/ASME A403 WP 304-304L-304H-304LN-304N

ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti

ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H

Low temperature steel: ASTM/ASME A402 WPL3-WPL 6

High performance steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon carbide, PVC, PPR, RFPP (reinforced polypropylene), etc.

Aluminum alloy 30036061, copper, purple copper, brass

2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.

3. According to manufacturing standards, it can be divided into national standards, electrical standards, ship standards, chemical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.

4. According to its curvature radius, it can be divided into long radius elbows and short radius elbows. A long radius elbow refers to a pipe with a curvature radius equal to 1.5 times the outer diameter of the pipe, i.e. R=1.5D; A short radius elbow refers to a curvature radius equal to the outer diameter of the pipe, i.e. R=1.0D. (D is the diameter of the elbow, R is the radius of curvature).

5. If classified by pressure level, there are approximately seventeen types, 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.
