West-to-East Gas Pipeline
Thread Content
Who knows what this preservation technique is? The outside of the pipe is yellow. . . .
This is not corrosion-resistant; since the West-East Gas Pipeline is a pressure pipeline, paint is applied to it.
The yellow paint is applied to prevent corrosion. This pipeline has a diameter of 1000 mm; it crosses the valley and is installed in the air using a truss structure.
This is the section of the West-to-East Gas Pipeline (Phase I)’s Yellow River crossing project in Zhongwei, Ningxia; it has a diameter of 1016 mm and uses a three-layer PE anti-corrosion coating.
The anti-corrosion method used in this section is reinforced three-layer PE for anti-corrosion protection, and ** the marking paint is used
Natural gas pipelines on the ground are painted yellow
The parts of long-distance pipelines that are exposed above the ground are generally coated with **
Personally, I think it’s just a topcoat; the person upstairs mentioned 3PE, which probably refers to the buried section~
Triple PE anti-corrosion coating: The pipelines above ground level in gas pipelines are coated with YELLOW anti-corrosion paint. Applying YELLOW paint is specified by the standards – it’s meant to be eye-catching!
