Problems solved by technology

[0005] During pipeline construction, due to factors such as project suspension, construction surplus, and engineering standby, some steel pipes will be stored on site or in material reserves for a long time. Since steel pipes are often stored in the open air, when the open air storage time is long, Due to factors such as more rain, stronger ultraviolet rays, and improper storage measures, there will be various problems such as corrosion pits, thinning of the wall thickness after corrosion, edge warping of the end anti-corrosion layer, aging of the end anti-corrosion layer, and damage to the end of the counterweight layer. This will lead to downgrading of steel pipes, waste reduction treatment or reprocessing, etc., resulting in waste of resources

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. Wherei...

Abstract

The invention provides a protecting structure for a coated and weighted sea pipe and a protecting method. The protecting structure comprises a left-end sealing piece, a right-end sealing piece, a left-end protector and a right-end protector; the weighted seat pipe comprises a sea pipe base body, a corrosion-resistant layer and a weighting layer; the outer surface of the sea pipe base body is coated with the corrosion-resistant layer; the outer surface of the corrosion-resistant layer is coated with the weighting layer, wherein the weighting layer is shorter than the corrosion-resistant layer which is shorter than the sea pipe base body in length; the exposed outer surface of the sea pipe base body and the inner wall of the sea pipe base body are coated with anti-rusting coat; the left-end sealing piece seals the left end surface of the sea pipe base body, and then the left end surface is externally and additionally provided with the left-end protector; and the right-end sealing piece seals the right end surface of the sea pipe base body, and then the right end surface is externally and additionally provided with the right-end protector. The protecting structure and the protecting method provided by the invention have the advantages that the storage time of the sea pipe can be effectively prolonged and the quality of the sea pipe can be ensured.

Description

technical field [0001] The invention belongs to the technical field of sea pipe protection, and in particular relates to a protection structure and a protection method of a sea pipe coated with a counterweight. Background technique [0002] According to the World Energy Outlook released by the International Energy Organization in recent years, the top three sources of global energy demand are fossil energy such as petroleum, coal and natural gas, and their consumption is much higher than that of bioenergy, nuclear energy, water conservancy and other renewable energy, and is increasing year by year. . It can be seen that marine oil and gas resources will be an important source of future oil and gas production growth, and more than 50% of global oil and gas production and reserves will come from the ocean. Submarine pipeline transportation is the most economical, safest, and most important transportation method for offshore oil and natural gas. Through submarine pipelines, th...
