Abstract

The invention relates to a deep sea pipeline test pipe piece line-marking device and method. The device can comprise a base, a line-marking pen rack detachably installed on the base and a line-markingpen detachably installed on the line-marking pen rack; two sliding rails which extend in the length direction and in parallel and are spaced are arranged on the base, at least two pairs of rolling bearing supports which are spaced in the length direction are arranged between the sliding rails, and a test pipe piece to be marked is supported by the rolling bearing supports and can roll; the line-marking pen rack comprises two trapezoid supports and an angle measuring arc frame, and the two trapezoid supports are correspondingly and slidably connected to the two sliding rails; the angle measuring arc frame is fixedly connected to the upper ends of the two trapezoid supports, a sliding groove with the front and the back communicating is formed in the angle measuring arc frame, wherein the sliding groove extends in the circumferential direction, at least one side face is provided with an angle mark scale ranging from 0 degree to 180 degrees, and at least one hollow pen tube capable of moving along the sliding groove is installed on the sliding groove; and the line-marking pen is movably arranged in the hollow pen tube in a friction mode. The device is simple in structure, convenient to use and high in precision.

Description

technical field [0001] The invention belongs to the technical field in the production, laying and installation process of deep-water submarine pipelines, and in particular relates to an angle-adjustable test pipe marking device and method. Background technique [0002] The submarine oil and gas pipeline is the lifeline project of the country, and its safety is of great importance to my country's offshore oil development and national economic development. However, the marine environmental conditions are complex and diverse. Submarine pipelines are subjected to complex loads and environmental conditions such as self-weight, external hydrostatic pressure, internal pressure, rough seabed, and seawater corrosion. Buckling and buckling propagation, once the submarine pipeline is buckled and damaged, it will lead to extremely serious oil and gas leakage accidents, which will cause huge economic, social, political and ecological losses to the country. [0003] At present, the resea...
