Embodiment Construction
[0032] The present invention is described in detail below in conjunction with accompanying drawing:
[0033] The present invention provides a protective structure for coating counterweight sea pipes, comprising: a left end seal, a right end seal 6, a left end protector and a right end protector 3; figure 1 Only one end of the protective structure coating the counterweight sea pipe is shown in section. figure 2 It also only shows a schematic view of the structure of one end of the counterweight sea pipe equipped with a seal.
[0034] The counterweight sea pipe includes a sea pipe substrate 4, an anti-corrosion layer 2 and a counterweight layer 1; an anti-corrosion layer is coated on the outer surface of the sea pipe substrate to protect the sea pipe substrate from corrosion; a counterweight layer is coated on the outer surface of the anti-corrosion layer, Thereby increasing the weight of the sea pipe itself, thereby increasing the stability of the sea pipe underwater.
