管模是生产混凝土压力管的专用设备之一,分外模和内模两大部分。一阶段管外模的价格较贵,一套直径1200毫米外模单价约2万元。总结我厂多年生产实践,两片式结构外模(下称两片式外模)的使用寿命约3500次,摊入每根混凝土压力管的外模折旧费平均5元多。外模的结构形式是直接影响外模使用寿命的主要因素之一,同时又是影
The tube mold is one of the special equipments for producing concrete pressure pipes, and the two parts are the outer mold and the inner mold. The price of the first-stage tube outer mold is more expensive, and the unit price of a set of 1200 mm outer mold is about 20,000 yuan. Summarizing our plant’s multi-year production practice, the service life of the two-piece structural outer mold (hereinafter referred to as the two-piece outer mold) is about 3,500 times, and the depreciation cost of the outer mold that is charged into each concrete pressure pipe is more than 5 yuan on average. Outer mold structure is one of the main factors directly affecting the service life of the external mold, but at the same time
