Boiling tube - Wikipedia, the free encyclopedia (183 words) |
 | A boiling tube is a large cylindrical vessel used to strongly heat substances in the flame of a bunsen burner. |
| A boiling tube is essentially a scaled-up test tube, being about 50% larger in every aspect. |
| Boiling tubes are commonly made from Pyrex glass which can withstand high temperatures. |
| Patent 4059147: Integral finned tube for submerged boiling applications having special O.D. and/or I.D. enhancement (2869 words) |
| Heat transfer tubing adapted to be submerged in a liquid to be boiled as a result of transfer of heat from the interior of the tube to the liquid. |
| Tubing as defined in claim 6 in which the helix angle of said fins is related to the helix angle of said ribs such that each rib convolution extends axially of the tube to cross a multiplicity of fin convolutions. |
| This tubing, as in the prior Zatell patent, is produced by drawing integrally finned tubing through a circular die in such a way as to bend the fin convolutions transversely so as to bring the tip of each fin convolution into proximity to the side wall of the adjacent fin convolution. |
