Qingdao Hexin Machinery Co.,Ltd

Tubes are used in hydrogen, methanol, and ammonia reformer furnaces, which are widely used in petroleum and chemical industries. HEXIN tubes are made of centrifugally cast from heat-resistant alloys such as HK-40, HP-50, Nb-modified HP, and micro-alloyed HP. (Reformer tubes, centrifugal casting reformer tubes assemblies, heat resistant petrochemical tube) At HEXIN™, we select only the new raw material ,like NICKEL plate, Chrome alloy. We use the currently worldwide first class spun casting machine designed with Germany technology, imported Spectrometer, boring machinery, and all the first-class professional inspection facilities in-house. (Reformer tubes, centrifugal casting reformer tubes assemblies, heat resistant petrochemical tube) To avoid the damage of the tubes on operation like creep damage, thermal shock, external oxidation, internal carburization, we control the quality of the tubes from the incoming raw material like weld filler material, molten materials, PMI is the first step, then we use Spectrometer to check chemical composition for each heat of molten, Eddy current testing,Ultra sonic testing,Radiography testing,Dye penetrant test, leak test,etc. (Reformer tubes, centrifugal casting reformer tubes assemblies, heat resistant petrochemical tube)
