Web1 de sept. de 1995 · Heating tubing to a red hot condition does have a place in bending. Bending causes the metal to harden somewhat. So, by heating the tubing you can anneal it and continue the bending carefully after the tube cools. In other words, it is possible to make bends over a smaller radius if you anneal the tube once or twice as the bend progresses. Because of their composite structure and the way they are commonly manufactured, tubular heating elements are prone to two main types of error: 1. Length errors: In the same batch of heating elements, the length of the straight resistor (before bending) can differ 1% compared to the total. This variation … Ver más In the BLM GROUP bending systems, the difference in lengthof the heating elements can be compensated by software and/or mechanically.
