Pipe Bending

Bend is the use of complete sets of bending equipment for bending, divided into cold simmer and hot push two kinds of technology. No matter what kind of machinery and equipment and pipeline, most of them are used to bend, mainly used for oil, gas, liquid, engineering bridge construction and so on.

Product Introduction

Tube Bending Description

Tube bending is any metal forming process used to permanently form pipe or tubing. Pipe bending can be shape-constrained or use a free-bend procedure, and can use either a hot-support or cold-forming procedure.

Bend Classification

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 Steels: ASTM/ASME A402 WPL3-WPL 6

Cast Steel, Alloy Steel, Stainless Steel, Copper, Aluminum Alloy, Plastic, Argon Pitch, PVC, PPR, RFPP (Reinforced Polypropylene), etc.
Aluminum alloy 3003, 6061, copper, copper, brass
2, to the production method can be divided into pushing, pressing, forging, casting, etc..
3, to the manufacturing standard can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.
4, according to its radius of curvature: can be divided into long radius elbow and short radius elbow. Long radius elbow means that its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R = 1.5D; short radius elbow means that its radius of curvature is equal to the outside diameter of the pipe, that is, R = 1.0D. (D is the diameter of the elbow, R is the radius of curvature).
5, if divided by pressure level: about seventeen, and the United States pipe standard is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160 XXS; of which the two most commonly used are STD and XS.
