化工行業對零部件(閥門)的要求
更新時間:[2017-02-17 17:41] 來源:www.jdfam.com 浏覽:

化工部對haughty行業的要求規範:

化工部工程建設技術規範【HGJ44-HGJ68-1999】 ;化工部标準;歐洲體系【HG20592-HG20605-1997】 ;化工部标準;歐洲體系【HG20613-HG20623-1997】。


 

化工部閥門的具體标準要求:

化工對閥門材質的标準要求;

 

碳化鎢塗層制備的特點:
1、焰流速度非常高,一般是音速的5倍。
2、噴塗粉末的速度也非常高,的可達2000米/秒。
3、塗層高度緻密,結合強度高,氣孔率能小于1%,結合強度可大于70Mpa。
4、塗層材料氧化程度低。失碳少,塗層硬度高。
5、某些特定材料,滿足修複場合,北京勤合科技。
6、高速的撞擊和強烈的變形使材料的晶格産生畸變,增加了材料的活性,從而增加了
   與相鄰的顆粒或基體材料生成物理結合的可能,塗層的可靠性極高。
7、工件不變形。
 
塗層産品特點:
1、耐磨塗層————硬度僅底于金剛石
2、耐腐蝕塗層———可耐硫化氫、飽和鹽水等腐蝕環境
3、耐氣蝕塗層———水輪機等水下工作環境
4、絕緣塗層————金屬工件耐壓3000V絕緣塗層
5、表面強化塗層——石墨表面強化抗粘連
6、高溫腐蝕塗層——耐溫1900度燒蝕,仿高溫粘連和損壞工件

不同國家對化工行業的标準要求大同小異(符合自己的國情而定)。各個國家對化工具體要求各有不同。所以在過程施工的時候一定要注意
