Problems solved by technology

[0002] Shallow sea oilfields have been developed for more than 10 years. At present, many subsea pipeline riser clips are damaged or fall off. There are many reasons for this phenomenon: ①Severe corrosion in harsh environments; ②Ship impact damage; ③Pipe clip installation and welding The quality is not up to standard, and the long-term ocean current and wave action will fall off; ④The pipe clamp bolts are loose, and half of the tiles fall off
The damage to the underwater pipe card caused by the above reasons has lost its fixing effect on the pipe, causing the riser of the submarine pipe to sway or vibrate under the action of the ocean current. Over time, it is very prone to fatigue damage, fracture or leakage safety accidents , will lead to direct and indirect economic losses and even the pollution of the marine environment. The harm is very serious. In addition, because the current underwater welding technology is still in the immature stage, it is also difficult to repair the underwater welding points; on the other hand, The size and specifications of the pipe clamps are difficult to determine due to the size and specification of the pipe clamps due to the specifications, positions of the standpipes, and on-site errors during installation, which makes the maintenance and treatment of the old-fashioned pipe clamps an unsolvable technical problem

Abstract

The present invention provides an underwater grouting typing submarine pipeline vertical pipe fixer, composed of a snap ring and an elastic capsule, the snap ring is column, composed of symmetrical bivalve arc, a pin roll connector and a bolt connector are set on two sides of the bivalve arc symmetrical lines respectively, a symmetrical circular tubes are set on the top and the lower of the bivalve arc, an insertion seal joint is set between the circular tubes, the symmetrical circular tubes are welded with the bivalve arc; multiple column elastic capsules are set in the vertical direction in the 120 degrees of the bivalve arc inner, the height of the elastic capsule is less than the height of the bivalve arc, the middle of each elastic capsule top is connected between the top circulating tubes by a straight angle elbow, the upper of each elastic capsule lower is horizontally connected with the circulating tube at the top of the lower, a return slurry tube and a grout pipe are set on the upper and lower tube in the vertical direction. The connector of the invention is smart, having convenient construction, creating better condition of the submarine pipeline vertical pipe fixing comprehensive treatment.

Description

1. Technical field [0001] The invention relates to an underwater grouting stereotyped seabed pipeline standpipe fixing device. 2. Background technology [0002] Shallow sea oilfields have been developed for more than 10 years. At present, many subsea pipeline riser clips are damaged or fall off. There are many reasons for this phenomenon: ①Severe corrosion in harsh environments; ②Ship impact damage; ③Pipe clip installation and welding The quality is not satisfactory, and the long-term ocean current and wave action will fall off; ④The bolts of the pipe clamp are loose, and half of the tiles fall off. The damage to the underwater pipe card caused by the above reasons has lost its fixing effect on the pipe, causing the riser of the submarine pipe to sway or vibrate under the action of the ocean current. Over time, it is very prone to fatigue damage, fracture or leakage safety accidents , will lead to direct and indirect economic losses and even the pollution of the marine envi...
