Tube hydroforming process: A reference guide -
01-01-2012· Tube hydroforming is one of the most popular unconventional metal forming processes which is widely used to form various tubular components. By this process, tubes are formed into different shapes using internal pressure and axial compressive loads simultaneously to force a tubular blank to conform to the shape of a given die cavity.

Tubular Stamping | Mills Products
Also known as tubular stamping, tube stamping is a relatively new technology used to produce complex, tubular parts that are generally uncommon in the stamping world. Tube stamping offers design advantages, greater strength-to-weight ratios and up to 30% lower manufacturing costs than screw-machined parts, die casting and aluminum extrusions. We can often implement special design Read

Increasing the Efficiency on ERW/HFI Tube Mills:
The process of welding tube and pipe requires several variables to be in check for efficient stable production. The material type, gauge, edge condition, tooling setup, and weld heat are just a few of the factors that quality control managers, mill supervisors, and operators must pay attention to in their efforts to achieve output and efficiency targets.

Rolling processes - Al-Mustansiriya University
Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required. Hot-rolled metal is generally free of

Calculating Mill Drive RPMs: Is Your Mill Up to
Insure the trim is not adjusted too fast, so the tooling is not "spinning" on the tube, resulting in the lost of drive, marking and premature tooling wear in this section. This formula works for rounds and any shape on any tube/pipe mill line. Use our contact form below to request more information on tube and pipe or roll forming products.

24-07-2018· The mandrel mill shell is then reheated in a reheat furnace so that it can complete the final rolling process and gain its final dimensions and micro-structural qualities. Upon exit from the reheat furnace, the tube receives a high-pressure water descale, removing the iron oxide scale that formed in the reheat furnace.
Welded roll forming system versus tube mills:
Forming some shapes on the tube mill simply isn't possible, but a welded roll forming mill can form highly complicated shapes quite readily. Also consider the outside corner radii of those shapes. In some cases, a tube mill can form those radii down to 2 times the material thickness, but this isn't typical.
