EPiC database - Steel pipe

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.<br><br>Steel is a ferrous metal and is an alloy of iron and carbon, as well as potential other elements. It has a very high tensile strength. Steel has been used in the construction industry for over a century.<br><br>The core material for making steel is iron, which is found in iron ore. Iron is extracted from iron ore in blast furnaces through the smelting process, while controlling for the content of carbon. The molten steel is usually further processed before being extruded into circular pipes.<br><br>Steel pipes are often used in pile foundations, plumbing and as columns (usually filled with concrete).

本材料隶属于免费的建筑环境性能（Environmental Performance in Construction, EPiC）数据库。该数据库采用全面的混合生命周期清单方法，收录了250余种建筑材料的隐含环境流系数。

钢材属于黑色金属，是以铁与碳为基础的合金，可掺入其他元素，其抗拉强度极高。钢材在建筑行业的应用已有百余年历史。

钢材制备的核心原料为铁矿石中赋存的铁。通过高炉冶炼工艺从铁矿石中提取铁，并可精准控制碳含量；熔融态钢材通常需经进一步加工后，方能被挤压制成圆形钢管。

钢管常被应用于桩基础、给排水系统，也可用作（通常填充混凝土的）结构柱。
