■  各類管子、彎頭、異徑管、管路補償器、三通、四通、儀表接頭及過濾器等
一、管路補償器
用以補償器路的熱脹冷縮引起的尺寸誤差及泵出口與玻璃、石墨等脆性材料設備連接由于震動而引起的順壞。
二、過濾器
   適用于各類管路上用以過濾器內介質雜質，確保流程裝置中設備安全運行，延長壽命，安裝事應注意方向性。
三、各類管子、彎頭、三通、四通
管子選用國家標準無縫鋼管，法蘭根據用戶要求可按HG、GB、JB、ANSL、JLS、DLN等國家8
四、襯里層材料
一般常用為聚四路乙烯（PTFE)、聚氯乙烯（PVP）、聚丙烯（PP）、PO等
五、試驗與經驗
 管路附件均以1.5倍公稱壓力進行試驗，全部襯里層表面進行電火花致密性試驗
