Problems solved by technology

[0004] However, underwater welding is mostly used to install sacrificial anode blocks underwater. Due to the existence of water environment and underwater pressure, the underwater welding process is very different from that on land.
The underwater welding technology is difficult, the welding quality is poor, and the installation cost is extremely expensive

Abstract

The invention discloses a pipe clamp type sacrificial anode installation device free from underwater welding. The device comprises a pipe clamp (1) and a sacrificial anode block (2), wherein the sacrificial anode block (2) is arranged on the pipe clamp (1) and is electrically connected with the pipe clamp (1). The sacrificial anode block and the pipe clamp are connected into a whole in advance through welding; due to the pipe clamp, the sacrificial anode block can be quickly fixed on an underwater protected metal pipe fitting, so that the sacrificial anode block and the underwater protected metal pipe fitting are conducted; therefore, the effect of preventing underwater metal structures from being corroded and damaged is achieved. By the device, underwater high-efficiency installation of the sacrificial anode block is realized and conduction connection is kept; and the device disclosed by the invention is simple in structure and free from underwater welding, can be installed quickly and is capable of shortening offshore operation time and reducing offshore operation risks and the operation cost.

Description

technical field [0001] The invention belongs to the field of offshore oil engineering, and specifically refers to a tube clamp type sacrificial anode installation device free of underwater welding. Background technique [0002] The marine environment is a severely corrosive environment. Seawater is the most abundant natural dielectric. In the surface seawater of the ocean, the normal salinity ranges from 32% to 37.5%, which is the most corrosive range. The chloride ions in the salt will destroy and It hinders the passivation of metals and is called "metal virus". Most of the steel structures of offshore oil engineering are eroded by seawater or foggy marine atmosphere. In a marine environment, steel corrodes approximately 10 times faster than in the atmosphere. According to statistics, the losses caused by corrosion of offshore oil projects are more than six times the sum of losses caused by natural disasters such as earthquakes and typhoons. [0003] At present, in order ...
