Russian clients visit GNEE Group for API 5L X65 3PE pipeline

We were pleased to host a high-level technical and procurement delegation from a prominent Russian oil and gas enterprise this week. The visit was centered on the strategic procurement and technical alignment for API 5L X65 (L450) PSL2 pipes with 3PE anti-corrosion coating, destined for a major natural gas trunkline project in the Far East region.

A significant portion of the visit was dedicated to our automated 3PE (Three-Layer Polyethylene) coating line. 3PE is the gold standard for buried Russian pipelines due to its excellent electrical resistance and mechanical protection.
 

The delegation witnessed the multi-stage coating process:

• Surface Preparation: Achieving Sa 2.5 cleanliness via high-speed shot blasting.

• Epoxy Primer Application: Ensuring maximum chemical bonding.

• PE Extrusion: Achieving the precise thickness required by DIN 30670 and ISO 21809-1 standards.

• Holiday Detection: 100% spark testing to ensure zero pinholes in the anti-corrosion layer.

Quality Inspection (NDT)
 

• Online Ultrasonic & X-Ray: 100% scanning of the weld seams for our LSAW/ERW pipes.

• Hydrostatic Testing: Verifying the pipe's integrity at high-pressure ratings.

• HIC & SSC Testing: For projects involving "sour gas," we demonstrated our resistance to Hydrogen-Induced Cracking, a vital safety feature for modern Russian energy fields.

 

The visit concluded with a preliminary agreement for the first phase of the API 5L X65 3PE pipe supply. This visit not only strengthens our commercial ties with the Russian market but also aligns with the broader "Power of Siberia" energy corridor initiatives, reinforcing our role as a trusted global supplier of high-pressure pipeline solutions.
