HEXIN MACHINERY , producer of heat resistant castings

 HEXIN Machinery now has full capability sand casting , centrifugal casting , precision casting , machining, riveting, heat treatment, assembly and other main workshops,  After years of development in the production of heating furnace accessories (heat-resistant steel castings),  it has provided complete sets of heating furnaces and waste heat recovery systems, as well as centrifugal casting alloy furnace tubes, radiant tubes, steam reformer tubes, steam reformer cold  headers, steam reformer inlet pigtails in Incoloy800H,Wye fittings, reducers, plug headers,and sharp bends for many refining and chemical projects of PetroChina, Sinopec, CNOOC and Sinochem.  Rich performance and experience, quality and technical ability. Especially the large-scale heat-resistant alloy steel castings with large size, high grade and complex structure have extremely obvious advantages in technology and experience. Centrifugal cast tubes, cast tube sheets, convection intermediate tub...

The alloy steel castings produced by HEXIN Machinery have good surface quality, high dimensional accuracy, and no slag inclusions, sand holes,  shrinkage holes, cracks and other conventional casting defects, major products for petrochemical industry like: Centrifugal cast tubes, cast tube sheets, convection intermediate tube supports, hooks, tube sheets brackets and hangers, various furnace doors/peep doors or observation doors,  air preheaters, flue baffles, butterfly valves, quick-opening dampers, compensators, flue duct systems, etc. The furnace hooks are used to hang furnace tubes in heating furnaces.  They are used in high-temperature working conditions. The material has high temperature resistance like ASTM A351 Gr.HK40. The draw tube sheet hanger is used to fix the furnace tube in the heating furnace and is installed on the side wall of the heating furnace.  It is produced by static casting process. The material has high temperature resistance. The general m...
