Large sample-loading amount multifunctional deep sea environment sample frame, test device and test method

Abstract

The invention provides a large sample-loading amount multifunctional deep sea environment sample frame, a test device and a test method. The design of the sample frame meets requirements of simultaneously performing deep sea environment corrosion aging tests of plenty of materials at a specific depth. The number of standard samples capable of being loaded is 300 to 600, and environment tests of components and simulation parts can be carried out. Modularized design is adopted for material corrosion standard sample installation, and samples first form a sample string and then are fixed to the sample frame, so as to achieve effects of facilitating on-site installation and sampling. Corresponding tool clamps can be designed for non-standard samples according to shapes (pipe fittings, flanges and spheres and the like). The device can simultaneously carry out corrosion aging tests of plenty of materials and components and is high in test efficiency. Environment testing devices are integrated, so that more environment parameter data can be obtained. Modularized design is adopted for sample assembly, installation and replacement operations during marine operation are facilitated, laying time is reduced, and marine test safety is improved.

Description

technical field [0001] The invention belongs to the field of marine natural environment corrosion test devices, and relates to a sample frame, a test device and a test method in terms of environmental adaptability evaluation of metal materials, coatings and components in deep sea environments. Background technique [0002] The deep sea is rich in oil, gas and mineral resources. According to statistics, two-thirds of the world's existing oil and gas reserves come from the deep sea. At present, developed countries have begun to develop technologies and equipment for deep-sea oil and gas exploration at a depth of about 3,000 meters. China's offshore oil development is moving towards the deep sea. The South China Sea has very rich oil reserves, but 75% of them are located in the deep sea of ​​2000-3000 meters. Therefore, it is urgent to carry out the design and development of relevant deep-sea equipment. The service environment of deep-sea engineering equipment is in seawater t...

AI Technical Summary

Problems solved by technology

This kind of device requires high requirements for the test site, and the seabed must be flat and hard sea mud with a large area; the sample frame sits on the seabed for a long time, and it is prone to bottom suction, and a recovery ship with a large tonnage is required for recovery.

The type and quantity of materials put into the second device are limited. Generally, only a few kinds or more than a dozen samples can be put into each depth, and the sample size is small; the sample frame of the device is only suitable for single metal tests, and cannot Corrosion test of samples of other types (components, simulated parts)
