Adjustable calibrator makes better pipe faster.


A patented calibrating sleeve from Rival A/S in Skanderborg, Denmark, can change pipe diameter and wall thickness on the fly, avoiding hours of downtime The time during which a computer is not functioning due to hardware, operating system or application program failure. . It has a series of 32 separate rings or hoops that close on themselves like tightening a belt. By staggering the closures so they don't line up, the rings can keep the pipe profile round. Lateral pressure (Mech.) a pressure or stress at right angles to the length, as of a beam or bridge; - distinguished from longitudinal pressure or stress.

 is adjusted with two wedges outside the cage of rings. It has been on the market since 1997, but in the past year, Rival has redesigned the sleeve inlet, adding direct water cooling Water cooling is a method of heat removal from components. As opposed to air cooling, water is used as the heat transmitter. Water cooling is commonly used for cooling internal combustion engines in automobiles and electrical generators.  for more lubrication lubrication, introduction of a substance between the contact surfaces of moving parts to reduce friction and to dissipate heat. A lubricant may be oil, grease, graphite, or any substance—gas, liquid, semisolid, or solid—that permits free action of  and faster heat removal. Rival will exhibit at the K 2004 show in Dusseldorf, Germany, this October. Tel: +45 (86) 57 71 77 * PT Direct: 244LD
