VIENERGY | Pipe

What we do best

Strength, consistency, and
certainty in every length

Our pipes are built to perform in harsh field conditions—high pressure, corrosive media, thermal cycling, and long-distance routing. By pairing strict metallurgy control with reliable weld integrity and precise dimensional tolerance, we help operators maintain pipeline safety, minimize leak risks, and secure consistent throughput across the asset’s lifecycle.

Certified quality with
engineered-to-spec manufacturing

We offer a full range of API-grade casing & tubing and transmission pipes—covering H40, J55, K55, N80, X-grades and more. Each product is manufactured to API 5CT, API 5L, GOST, or GB/T standards, with options for HFW/ERW or SSAW welding, specialized coatings, tight OD/ID tolerance, and cut-to-length supply. Custom production is available to match unique well, pipeline, or utility requirements without compromising delivery reliability.

Casing & Tubing Pipe

Petroleum Casing & Tubing Pipes include a full range of non-upset and external-upset tubing in steel grades H40, J55, K55, and N80. Manufactured in accordance with API Spec 5CT, they offer stable, reliable quality and fully meet the operational needs of oil field extraction.
