龍吉宇精密股份有限公司自1989年來運用離心鑄造技術生產高品質的特殊合金離心鑄管以及離心鑄件。

其製作原理乃利用熔融之金屬鋼液倒進高速旋轉之金屬模具中 ，將鋼液均勻地披覆於模具，由外向內慢慢凝固即成型為中空之無縫鋼管。因強大之離心力將所有雜質,氣孔..等排除，克服了一般鑄造無法達成之任務，無論機械性質,晶粒組織狀態及晶粒度均處於極優越狀態。

耐腐蝕合金, 耐熱合金, 耐磨合金為主要的離心鑄造材料，目前研發出的離心鑄造無縫鋼管材質已超越100種。使用這些材料製作出的離心鑄造產品都經過嚴格的品質管制及認證，並依照顧客的需求，做內外徑粗或精加工。 龍吉宇生產的離心鑄管已運用於國內外石化業,熱處理爐業,汽車業,鋼鐵業,造紙業,電廠…等廠商 。
