When materials are rather expensive, like stainless steel rectangular tubes, it is often beneficial to the customer to try to utilize each length most efficiently. It is well known throughout the industry that the roller bending process requires extra length on both ends of a rolled member. This length is used in order for the machine . . . → Read More: Rolling Tubing and Saving Stainless Steel: 2 from 1
A customer who prides himself as a provider of technology-based solutions called while working on a design. He required bending a 3 x 3 stainless steel tube to serve two purposes: as a frame for a tunnel and as a ducting system to convey fluids. The tunnel is 14ft wide and 70ft long. It covers a conveyor which . . . → Read More: Stainless Steel Tube Bending for the Food Industry
Steel tees up to 22 x 142-1/2 can be curved stem in, stem out or stem up. At times, however, either the stem is too large or the radius is too tight to roll a tee. One solution is to fabricate a built-up tee.
For example, a customer wanted two tees with a 14in stem ½ in . . . → Read More: Built-up Curved Tees
The problems associated with Rotoform bending of steel pipe have caused major corporations to establish policies which forbid its use.
A multi-national conglomerate, major producer of bulk liquid storage tanks with 16,000 employees is at the forefront of this policy.
In a recent publication the company stated that “the use of “Rotoforming or equal is prohibited for bending . . . → Read More: The Dangers of Rotoform Bending of Steel Pipe
Curved steel has literally countless applications. Curved structural steel, curved steel plate and curved steel sheet—all bent by companies that specialize in curving steel sections—typically end up as parts within a larger structure, e.g. a building, or a canopy.
Perhaps you might be interested in knowing whether the market you are in uses a significant amount of . . . → Read More: Where Does the Curving of Structural Steel Fit in the Overall Construction Market?
Methods to curve pipe include rotary draw bending with a mandrel on a pipe bender and rolling pipe on a three-roll bender (also called an angle roll, a pyramid roll, or a section bender). For simplicity, let’s call the first method “BENDING” and the second “ROLLING.”
Let’s say you require 5D bends for basketball backboard supports.

Bending pipe to a tight radius often requires the use of an internal mandrel to keep the round pipe from becoming oval, wrinkling or cracking during the bending process. Original equipment manufacturers (OEMs) usually do not have the expertise to do mandrel bending of pipe. Or they choose to subcontract this work because specialists can do . . . → Read More: Bending Pipe Into a Flat-Back U with an Internal Mandrel
