薄壁不锈钢管材与传统棺材的性质比较

薄壁不锈钢管作为供水、供气、供油用管材与传统管材相比较具有很多优势，它洁净卫生，抗拉强度是碳钢管的2倍、铜管的3倍，热传导率为碳钢管的1/4、铜管的1/25，能成倍减少热水输送中的热能损耗，其热胀冷缩系数是碳钢管的1.5倍、塑料管的1/4，与铜管相近。

Thin-walled stainless steel pipes have many advantages compared with traditional pipes as water,gas and oil supply pipes.They are clean and hygienic,with tensile strength twice that of carbon steel pipes and 3 times that of copper pipes.The heatconductiv contraction coefficientis 1.5times that of carbon steel pipes and1/4 of plastic pipes,which is similar to copper pipes.See the chart for specific parameters.
