NPS, or nominal pipe size, is the North American set of size standards for pipes that are used for temperatures and pressures of all ranges. The nominal pipe size identifies the size of the diameter of the pipe’s hole with a non-dimensional number. Using the NPS, a pipe is identified by its diameter and then with another non-dimensional number for the pipe’s wall thickness.
Stainless steel bending is a functional, aesthetic way to complete many metal design tasks. Bending is often preferable to welded or mechanical connections, as when a seamless design is required, or there is concern about the crevices created by mechanical joints. Crevices can be particularly problematic for the food and pharmaceutical industries since they may introduce contamination.
Metal bending and rolling are key processes in the metal and alloy manufacturing and fabrication industries. While Section Bending processes vary with material, size, and thickness, but needn measures ensure the integrity, performance, and longevity of your final product. Bending operations include compression bending, roll bending, rotary draw bending, and other specialty tooling methods.
Although Section bending machine many metals including aluminum, brass, copper, and other alloys, carbon steel bending is curved in higher volume than any other metal.
Carbon steel comes in a wide variety of grades each with its special characteristics and mechanical properties. Some grades bend better than others; some are more easily machined; and some are more wear-resistant.
Bars are most commonly used for smaller manufactured parts and for industrial applications.
Square bars can only be bent as one style (i.e. there is no strong axis or weak axis to bend against).
Tube is bent around a fixed radius die with a mandrel insert in to prevent it from collapsing during bending. The tube or pipe is clamped against the die and this is then rotated whilst the pressure die moves in a straight linear motion. This is the most common form of bending.
Bent steel components don’t just “walk out” of the rolling mill. Bent steel members are made of straight materials and are bent by your bending company to your requirements.
The bending process does not affect the strength or structural integrity of the steel. When the shape is successfully bent without any buckling or local cracks in the steel, under actual conditions of use, the component will withstand much less stress than that associated with the bending operation. Once the bending is completed, the member can be expected to perform as needed.
Tube bending is a metal forming process that is used to shape pipes or tubing.
Bending machines take straight tube stock and create a shape involving single or multiple bends. This allows the tubing to be formed in any fashion to fit the application’s specific needs. Round tubes are typically used for tube bending, but square or rectangular tubes can also be bent in order to meet your specific needs.
Because bars are solid metal, they bend very well. Bending bars is the easiest when the sections to be bent are rounds, half rounds, squares, hexagons, or rectangular, and need to be bent “the easy way.” Bending bars the easy way (y-y axis) creates a belt-like shape; bending bars “the hard way” (x-x axis) creates what looks like a giant metal washer. All else being equal, bending bars that are flat the hard way is the most difficult bar bending process.
