冷拉管时,由于受到拉伸设备的限制,经常要碰到在现场如何确定料管合理长度的问题。冷凝管以及某些作其他用途的管材都要求定长供货,因此,拉制前必须事前计算料管的应有长度。凭经验估计,往往会出差错,造成浪费。例如可以一开三的料管,误开为二投料,则无形中浪费了一根成品管。反之,如只能一开二的料管,误开为三,则到最后会因达
Cold drawing tube, due to the constraints of stretching equipment, often encountered in the field how to determine the reasonable length of the tube material. Condenser tubes and some other applications require a fixed-length pipe delivery, therefore, before drawing must be calculated in advance the expected length of the pipe. By experience, we often make mistakes and waste. For example, you can open three tubes, mistakenly open for the second vote, then virtually waste a finished tube. Conversely, if only one open two tube, mistakenly open for three, then up to the final due
