送粉雙金屬耐磨管

送粉雙金屬耐磨管,此管是我公司生產的較大口徑的管件

陶瓷耐磨管與雙金屬耐磨管的應用成本比較:
目前市場耐磨管的價格是:雙金屬耐磨管每噸1.8萬元左右,鑄石耐磨管每噸1.3萬元,耐磨貼片管每噸1.7萬元。這幾類彎頭特別重,它們是以重量來謀利潤。也就是說,一個雙金屬耐磨管的價格是陶瓷耐磨管的兩倍,用一個雙金屬耐磨管的錢,可以買兩個陶瓷耐磨管,陶瓷耐磨管的使用壽命是這種雙金屬耐磨管的2-3倍,用價格與使用壽命比,也就是用1/5的雙金屬耐磨管的錢買一個陶瓷耐磨管。
例如:2×600MW超臨界機組送粉管,管徑為φ530×10,采用雙金屬耐磨管,重量為W=1700kg,全部彎頭總重(2臺爐)約為500~600噸;而采用陶瓷耐磨管,其重量僅為W=450kg左右,全部彎頭總重(2臺爐)約為110~130噸;對比可看出,采用陶瓷耐磨管,最直接的是使輸送介質管重量大幅下降,投資至少節約200萬以上(雙金屬耐磨管單價按1.8萬元/每噸),還不包括重量下降使得煤倉間土建構架梁荷載的降低所帶來的經濟效益,以及支吊架材料的節省所帶來的經濟效益。
以上從性能和價格上對幾種材質的彎管進行了對比,可見耐磨彎頭無論是初期投入還是運行費用都是最具性價比的!
