Technology and Material
◪1.All the steel pipes used are hot-pressed seamless steel pipes. All the main materials are Q235 steel, in line with GB700-88
◪2.The pipe-to-pipe connection and pipe-to-connector connection use a butt weld or full-period fillet weld.
◪ 3.All butt welds must be cut-through welds. These welds are not specified and the weld grade is Grade 3.
◪4.Where the weld is not a fillet weld, the weld foot is not less than 4mm. All exposed mouths have sealing plates.
◪ 5.Bolts are galvanized common large hex head bolts, in line with GB5780-86; nuts in line with GB41-86.
◪ 6.Manual welding uses E43xx electrodes, welding wires and fluxes for automatic and semi-automatic welding.
◪ 7.Film fabric using white PVDF film with its total weight 850g/㎡.
◪ 8.The wire rope material conforms to the universal wire rope standard "GB/T8918-1996".
