Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] figure 1It shows the layout of a full-scale pipeline deep-sea complex marine environment load joint loading test system. This full-scale pipeline deep-sea complex marine environment combined loading test system includes a modularly arranged test chamber system 1a, a gantry crane mechanism 1b, a high-pressure water system 1c and an electronically controlled hydraulic oil source 1d. The test chamber system 1a and the gantry crane mechanism 1b are arranged on the base 1f through the orientation slide 1e, and the base 1f is fixed on the foundation 1h through the anchor bolts 1g. The high-pressure water system 1c and the electronically controlled hydraulic oil source 1d are arranged on the side of the test cabin system. The test cabin system 1a includes three truss supports 1i fixed on the base 1f by bolts arranged along the...

Abstract

The invention relates to a combined loading test system for full-scale pipeline deep-sea complex marine environment load, which belongs to the technical field of submarine pipeline safety evaluation test. The test system includes a modular test chamber system, a gantry crane mechanism, a high-pressure water system and an electronically controlled hydraulic oil source. On the side; under the truss support and the gantry crane mechanism, there are axial loading cabins, bending moment loading cabins and torque loading cabins. The system can realize the loading of single load or load combination, and can accurately simulate the loading conditions of deep sea oil and gas pipeline installation and operation. It can realize the simulation of load conditions and boundary conditions of oil and gas pipelines in the deep sea environment. It has two loading methods of force control and displacement control, and can realize cyclic loading of single load or load combination. It can carry out fatigue failure tests of deep sea oil and gas pipelines in situ to verify fatigue Ultimate bearing capacity, revealing the mechanism of fatigue failure.

Description

technical field [0001] The invention relates to a combined loading test system for full-scale pipeline deep-sea complex marine environment loads, which is used to carry out research on failure modes and damage mechanisms of full-scale oil and gas pipelines under different working water depths and internal pressure environments under the joint action of axial force, bending moment and torque. It belongs to the technical field of submarine pipeline safety evaluation test. Background technique [0002] Deep-sea oil and gas resources will occupy an important position in my country's energy system in the future, and deep-sea oil and gas pipelines are an important part of the development of deep-sea oil and gas resources. The development of safe and reliable storage and transportation technologies will become an important factor restricting their development and utilization. [0003] The main characteristics of deep-sea oil and gas pipelines are significantly increased design wall...
