Evaluating drawing lubricantsChlorinated lubricants, which have been phased out in Canada and Europe, are still used in many metal-forming applications in the U.S. This class of lubricants is under scrutiny in the U.S., so it makes sense to test alternative lubricants now. Evaluating a lubricant for drawing tube requires much more than simply measuring the draw load during a pull. A comprehensive test evaluates ease of... Read More... |
Replacing the tapered roller bearings in your mill tooling frequently?Overlooking a small component on a tube or pipe mill—even something as seemingly insignificant as the roller bearings inside the inboard and outboard stands—can lead to excessive downtime. Learning the proper way to install and maintain these bearings can extend their service life and improve the mill’s uptime. Read More... |
Heat-treating line pipe weld seamsAs the use of thick-walled pipe for API applications grows, so does the need to verify that it has been correctly normalized. Use of 2-D simulation verifies that the temperatures and heating pattern needed to obtain the desired strength and toughness have been achieved. Read More... |
HPTR's past, present, and future—Part IIInitially developed in the 1950s for manufacturing tubing with ultrathin walls for nuclear fuel cladding, the high-precision tube roller (HPTR) continues to provide a fast, economical way to achieve extreme reductions in diameter and wall thickness.
