Tube Bending Standards

This standard establishes basic design criteria including preferred bend radii, straight lengths between bends, flattening and surface conditions in the bend area. Also included is a table of preferred tubing sizes and wall thicknesses and a formula for determining a minimum...

This standard defines criteria for acceptability of tube bends for hydraulic system metallic tubing.

1 Scope This specification is inactive with no replacement.

This standard provides details of bend radii used in the manufacture of rigid tubes. It also provides details of the minimum length of straight permissible between such radii during manufacture. This standard applies to rigid tubes conforming to EN 3717 and produced only in ASD...

Purpose: draw process equipment covered by this specification shall be of adequate power, rigidity, and accuracy to make tight radius thin wall bends in aluminum, mild steel, stainless steel, titanium, and other alloyed tubing for Aerospace vehicles, to the applicable military or Federal...

Method for determining the ability of tubes of circular cross-section to undergo plastic deformation in bending.

This Standard specifies a method for determining the ability of full-section metallic tubes of circular cross-section to undergo plastic deformation in bending.

The design rules are applicable to tubes for welding, e.g. according to DIN 2605 and bent tubes. The design rules take account [1] of the fact that in the case of loading of a tube bend due to internal pressure higher stresses occur on the inside of the bend and...
