Yantai Manoir Heat Resistant Alloys Co., Ltd, was established in 1991 and from its first startup, became specialized in the manufacturing of centrifugally cast tubes and static cast fittings made of heat-resistant alloys designed for petrochemical, steel, and float glass industries. Over 30 years, Yantai Manoir has acquired the know-how and strong expertise in manufacturing of proprietary alloys; equipped with the latest and most advanced tube automatic production line and inspection facilities. Most of the welders and NDT inspectors are qualified with ASME & EN codes, and Level II or III certifications.
