大型乙烯球罐材质的选用

Selection of Material for Large- Sized Ethylene Spherical Tanks

国内建造大型乙烯球罐时，就球罐材质的选用，即选用国产材料还是进口材料，争议很大。从技术角度上讲，大型球罐的材料选用，不论是国产钢材还是进口钢材，只要能满足设计的要求，都可以采用。

When building large - sized ethylene spherical tanks in China, there is no agreement on material choice, which is choosing domestic steel or imported steel. It is proved that any material can be used if it meets design request.
