Tube bending is any metal forming processes used to permanently form pipes or tubing. Tube bending may be form-bound or use freeform-bending procedures, and it may use heat supported or cold forming procedures. Form bound bending procedures like “press bending” or “rotary draw bending” are used to form the work piece into the shape of a ...
Tube flaring is a type of forging operation, [1] and is usually a cold working procedure. During assembly, a flare nut is used to secure the flared tubing's tapered end to the also tapered fitting, producing a pressure-resistant, leak-tight seal. Flared connections offer a high degree of long-term reliability and for this reason are often used ...
Fred A. Lennon and Cullen B. Crawford founded Crawford Fitting Company in Cleveland, Ohio, in July 1947 to manufacture the Swagelok tube fitting, which used a two-ferrule design to “swage” or form the tube and lock it into place. One year later, Lennon bought out Crawford and continued to grow the business.
Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater the material flexibility (as the radius of curvature decreases , the curvature increases ).
The first punch & die type tool for notching tube & pipe was invented in Chicago by Julius Vogel, who was issued a US patent in 1938. [1] The accuracy of punch notching is good, depending on the care with which it's carried out. For manual folding work, prior notching can often improve resultant accuracy of the folding itself.

Common sizes are 15 mm and 22 mm. [7] Other sizes include 18 mm, 28 mm, 35 mm, 42 mm, 54 mm, 66.7 mm, 76.1 mm, and 108 mm outside diameters. Tubing in 8 mm and 10 mm outside diameters is called a "micro bore" and is easier to install, although there is a slightly increased risk of blockage from scale or debris.
Bending A chimney starter, a sample product of bending. Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.
