Desenho de Engenharia de Tanque de Armazenamento

A professional engineering technical drawing on paper showing a shampoo liquid storage tank (洗发水料液储罐). The drawing includes: 1) Main front view of a vertical cylindrical tank with elliptical or flat heads, with detailed dimension lines showing tank diameter, height, wall thickness, and nozzle locations. 2) Top view showing the circular tank with pipes, manhole, and instrument connections. 3) A nozzle table (管口表) listing nozzle codes (N1, N2, N3, N4, N5), specifications, and purposes. 4) Drawing parameter table with design pressure, design temperature, welding coefficient, corrosion allowance, material, and capacity data. The drawing style matches Chinese engineering standards, hand-drawn look on grid/plain paper with blue or black ink lines, similar to the reference drawing.
