According to the news from the PetroChina Pipeline Bureau, the first batch of insulated finished pipes on the second line of the Sino-Russian crude oil pipeline has been successfully rolled off the line recently and shipped to the construction site
.
This is the first time that low-temperature insulation pipes have been laid in China's pipeline construction
.
This means that low-temperature-resistant insulation technology will be tested for the first time in the permafrost zone of the Sino-Russian second-line project
.
? The insulation pipeline of the China-Russia second line project passes through the permafrost and seasonal frozen soil areas.
In order to prevent the pipeline transportation temperature from causing the permafrost melting to cause settlement, landslides, mudslides and other disasters to cause damage to the pipeline, Mohe to Canada The 106-kilometer pipeline of Gedaqi Section 1 and 2 adopts the "pipe-in-pipe" forming high-pressure foaming process
.
In the design, it breaks the domestic convention of normal temperature insulation technology and adopts low temperature resistance insulation technology.
The finished insulation pipe will meet the ambient temperature of minus 55 degrees Celsius to 50 degrees Celsius, and the standard is higher than the technical specifications of extreme cold countries such as Northern Europe, Canada, and Russia
.
? This process is the first application in China.
To ensure the smooth implementation of the project, the Pipeline Bureau Anticorrosion Company built a thermal insulation plant in the northernmost part of China in Tahe County Industrial Park, Heilongjiang, to ensure that the first batch of low-temperature-resistant thermal insulation pipes were successfully rolled off the assembly line with quality and quantity
