| 管廊模具的发展历程在告诉我们排水管质量要注意选材，排水管选用钢件，铁件制作，在进行表面处理时， The development process of pipe gallery mold tells us that we should pay attention to the selection of material for drainage pipe quality, and the drainage pipe is made of steel parts and iron parts, 具备以下三点优势： 1.增加部件表面对塑性变形和断裂的抵抗能力，使表面产生应力，提高疲劳断裂强度。2.减少部件表面缺陷和由于机械加工所带来的损伤，从而降低应力集中；3.增加其表面精细度及油漆吸附力，使其表面美观，油漆不易脱落液压钢坝。水泥管模具是是井体钢模具的一种别称，它的形状类似于锥形体，是用于井盖下面的一种水泥制品，分为内管和外观中间是水泥制品，一般井体的上口直径可以配套70井盖 It has the following three advantages: 1. Increase the resistance of the component surface to plastic deformation and fracture, so as to generate stress on the surface and improve the fatigue fracture strength. 2. Reduce the surface defects and damage caused by machining, so as to reduce the stress concentration; 3. Increase the surface fineness and paint adsorption force to make the surface beautiful, and the paint is not easy to fall off. Cement pipe mold is another name for steel mold of well body. Its shape is similar to that of cone. It is a kind of cement product used under the well cover. It is divided into inner pipe and appearance. The middle part is cement product. Generally, the upper diameter of well body can be matched with 70 well cover |
