Embodiment Construction
[0023] Such as figure 1 — image 3 As shown, the present invention includes: a base 1 for connecting the sub-pipe and the main pipe, a top protective cap 2 that can be docked with the inside and outside of the base 1, and a sub-pipe limit embedded in the base 1. The bit card 3 and the binding band 4 that connects the base 1 and the top protective cap 2 together by binding.
[0024] The upper and lower ends of the above-mentioned base 1 are respectively provided with an arc-shaped limiting groove for cooperating with the submarine pipeline and accommodating the sub-pipe limiting card 3 .
[0025] The above-mentioned top protection cap 2 is a semicircular structure.
[0026] The above-mentioned sub-tube limit card 3 is composed of several arc-shaped cards connected together, and the inside of the butt-connected arc-shaped cards is circular;
[0027] Both sides of the above-mentioned arc-shaped card are provided with concave and convex grooves capable of inserting and butting ...

A separating type son-mother tube clamp comprises a base, a top protection cap, a son tube limiting clamp and a binding belt. The base is used for connecting a son tube with a mother tube. The top protection cap can be in butt connection with the inner side and the outer side of the base. The son tube limiting clamp is embedded into the base. The base and the top protection cap are connected together through the binding belt. The upper end and the lower end of the base are each provided with an arc limiting groove which is used for being matched with a seabed pipeline and contains the son tube limiting clamp. According to the separating type son-mother tube clamp, the son tube and the mother tube can be connected, meanwhile, adjustment can be carried out according to changes of the distance between the son tube and the mother tube, only one clamp is used for being applicable to connection of the son tube and the mother tube with various distances, and the problem that an existing clamp cannot be replaced is solved; meanwhile, limiting and protection can be provided for the son tube and the mother tube.
Description
technical field [0001] The invention relates to an installation and protection device of a submarine pipeline, in particular to a separate sub-pipe clip used for installation, connection and protection of the submarine pipeline. It belongs to the field of marine engineering. Background technique [0002] Submarine pipeline is an important part of deepwater oil and gas field development engineering construction. In order to save the construction cost of submarine pipelines or simplify the construction procedures of submarine pipelines, in some production projects, it is possible to adopt the method of bundling two large and small submarine pipelines together in a certain form. The pipes in which two pipes, one large and one small, are bound together are called son-mother pipes. [0003] During the installation process of the mother and child subsea pipes, clamps are needed to complete the connection between the child pipes and the mother pipe. [0004] At present, the exis...
