全国重点工程——宁波北仑港电厂所需的直径3m混凝土循环水管的管芯已于1988年7月22日在浙江省火电建设公司镇海混凝土管加工厂浇注成功。每根重达27t、长4m的混凝土管管芯的模具(简称3m管模)是由能源部杭州机械设计研究所设计、富春江水工机械厂制造。脱模后的管芯表面质量及几何形状符合GB5696—85的规定。这套管模是能源部杭州机械设计研究所设计的第三套产品,它在总结了前二套(即江苏电建三公司的
The national key project - Ningbo Beilun Port Power Plant required diameter 3m concrete circulating water pipe die was July 22, 1988 in Zhejiang Thermal Power Construction Company Zhenhai concrete pipe processing plant pouring success. Each weighing 27t, 4m long concrete pipe die (referred to as 3m pipe die) is designed by the Ministry of Energy Hangzhou Mechanical Design Institute, Fuchunjiang Hydraulic Machinery Factory. Die surface quality and geometry after demoulding consistent with the provisions of GB5696-85. This set of mold is the Ministry of Energy Hangzhou Mechanical Design Institute designed the third set of products, it is summarized in the first two sets (ie, Jiangsu Power Construction Company three
