Method for performing submarine glass fiber reinforced plastic pipeline lunching construction by using submarine glass fiber reinforced plastic pipeline joint

Abstract

The invention discloses a submarine glass fiber reinforced plastic pipeline joint and a method for performing submarine glass fiber reinforced plastic pipeline lunching construction by the joint. The submarine glass fiber reinforced plastic pipeline joint comprises a glass fiber reinforced plastic sleeve joint and two baffle ring devices, wherein the two baffle ring devices are fixed on outer edges of opposite ends of two adjacent glass fiber reinforced plastic pipes and sealed and sleeved at two ends of the lass fiber reinforced plastic sleeve joint; and the glass fiber reinforced plastic pipeline joint also comprises a fixing device which connects the two baffle ring devices in a rigid manner. The submarine glass fiber reinforced plastic pipeline joint not only has good sealing performance, but also can change flexible connection among glass fiber reinforced plastic pipes into rigid connection, so that spliced glass fiber reinforced plastic pipes can meet requirements of a pipeline lunching installation process, and the construction is simple, convenient and rapid; the joint is high in tenacity, and during hoisting, buffer corners exist on both ends of the joint, so that tension and fracture resistance of a product are enhanced; and at the same time, the joint can realize submarine lunching construction of spliced glass fiber reinforced plastic pipe sections, and compared with conventional glass fiber reinforced plastic pipe sections, the installation method is more convenient and rapider.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastic pipelines, and in particular relates to a submarine glass fiber reinforced plastic pipeline joint and a method for launching and constructing a submarine glass steel pipeline by using the joint. Background technique [0002] With the continuous development and improvement of mining technology, there are more and more deep-sea oil and gas production operations in my country, which requires the production of oil and gas to be transported to the destination through pipelines. At the same time, long-distance water transportation on the seabed also needs to be realized through submarine pipelines At present, marine flexible hoses are beginning to replace traditional steel marine steel pipes for transporting media such as water or oil and gas. When laying flexible hoses such as glass steel pipes, because the glass steel pipes are flexible pipes and the connections between them are ...

AI Technical Summary

Problems solved by technology

When laying flexible hoses such as glass steel pipes, because the glass steel pipes are flexible pipes and the connections between them are flexible connections, the traditional rigid pipe launch installation construction process cannot be used for construction, and only more complicated processes can be used. For construction, it is necessary to excavate a trench on the seabed first, then lay down the single-section glass steel pipe, and then let divers dive into the bottom to connect the glass steel pipe and backfill it. This construction process is relatively complicated and the construction efficiency is low.
