Raw Material Incoming Inspection: Select appropriate raw materials, usually pipes or tubes, and conduct reinspection to ensure that the materials meet the required standards, including checking the material certificate, chemical composition, mechanical properties, etc. Cutting: Cut the pipes or tubes into specific lengths according to the dimensions required for the butt - weld outlet nozzles using cutting equipment such as sawing machines or cutting torches. Heating: Heat the cut pipe sections to a suitable temperature range to make the materials more malleable. This is usually done in a furnace, and the heating temperature and time need to be strictly controlled according to the material type. Forging: Use forging equipment to forge the heated pipe sections to form the basic shape of the butt - weld outlet nozzles. Forging can improve the internal structure of the materials and enhance their mechanical properties. Heat Treatment: After forging, carry out heat treatment, such as annealing, quenching, tempering, etc., to eliminate the internal stress generated during forging, improve the material's mechanical properties, and obtain the required strength, toughness, and hardness. Shot Blasting: Use shot - blasting equipment to remove the oxide scale, rust, and other impurities on the surface of the parts, which can improve the surface quality of the parts and provide a good foundation for subsequent processing. Drilling and Machining: Use machine tools such as drilling machines, lathes, and milling machines to carry out machining operations on the shot - blasted parts, including drilling connection holes, machining bevels, etc., to meet the design and installation requirements. Marking: Mark relevant information on the machined butt - weld outlet nozzles, such as part number, specification, material grade, manufacturer's logo, etc., for easy identification and traceability. Inspection: Conduct a comprehensive inspection of the butt - weld outlet nozzles, including appearance inspection, dimensional inspection, non - destructive testing (such as ultrasonic testing, magnetic particle testing, etc.), and mechanical property testing, to ensure that the products meet the quality standards. Packaging and Shipping: After passing the inspection, package the butt - weld outlet nozzles according to the requirements to prevent damage during transportation and storage, and then ship them to the designated location.
