The inspection content includes appearance inspection to see if there are pits, cracks, scratches, heavy skin and uneven wall thickness, material, and model on the surface of the pipe. And analyze the chemical composition. The raw materials that pass the inspection can be blanked. When blanking, the material should be blanked with a sawing machine according to the data of the blanking process card. The finished material section should be clearly marked with quantity, specification, material, and if necessary, the number should be marked and transferred to the next process for pushing.
