单卡压式不锈钢管件的保护作用

网址:www.china-pipe.com.cn  2019-06-14  作者:admin    阅读:

单卡压式不锈钢管件经过成型焊接等工艺后,金属分子结构会发生变化, 经过1050℃的固溶处理 (采取氢气保护处理)对管件具有良好的保护作用:
The molecule structure of the single-clamp stainless steel pipe will change after forming and welding. The solid solution treatment at 1050 ("hydrogen protection treatment") has a good protective effect on the pipe.
一是可以消除管件焊接中的敏化现象,增强焊缝的耐腐蚀性能。二是可以恢复管件生产过程中的晶间变化,防止使用过程中的晶间腐蚀。三是可以消除管件生产过程中的应力,降低使用过程中应力腐蚀的可能。四是可以消除管件加工过程中的改性现象,恢复材料的耐腐蚀性能。五是可以还原不锈钢材料表面的自然光泽。
First, it can eliminate the sensitization phenomenon in pipe welding and enhance the corrosion rouruanji.37ix.com.cnmuliao.37ix.com.cnmuliaog.37ix.com.cnzhidaijiz.37ix.com.cn yawenzhi.37ix.com.cnwufangbuf.07858.netresistance of welds. Second, it can restore the intergranular change in the production process of pipe fittings and prevent intergranular corrosion in the use process. Thirdly, it can eliminate the stress in the production process of pipe fittings and reduce the possibility of stress corrosion in the use process. Fourth, it can eliminate the modification phenomenon in the process of pipe processing and restore the corrosion resistance of the material. Fifth, the natural luster of stainless steel surface can be reduced.
