Abstract

The invention relates to a deep-sea pipe test pipe scribing device and method. The device comprises a base, a scribing pen holder detachably mounted on the base and a scribing pen detachably mounted on the scribing pen holder. The base is provided with two spaced sliding rails extending in parallel along the length direction. At least two pairs of rolling bearing supports spaced apart in the length direction are disposed between the sliding rails. A test pipe to be scribed is supported by the rolling bearing supports and can roll. The scribing pen holder comprises two A-shaped supports and a cross beam. The two A-shaped supports can be slidingly connected to the two sliding rails. The cross beam is fixedly connected to the upper ends of the two A-shaped supports and is detachably providedwith at least one hollow stylus tube. The scribing pen is movably and frictionally arranged in the hollow stylus tube. The device has a simple structure, realizes a low preparation cost, is easy to use and has the high test pipe axial line and circumferential line drawing precision.

Description

technical field [0001] The invention belongs to the technical field in the production, laying and installation process of deep-sea submarine pipelines, and in particular relates to a marking device and method for deep-sea pipeline test pipe fittings. 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...
