Heavy-duty seamless hot-finished black steel tube 168x28 is a reinforced industrial profile engineered for massive mechanical loading and high-pressure fluid transportation. Manufactured from high-quality structural steel grade 20 (European equivalent P235TR1) through the hot rolling of monolithic cylindrical steel billets, this pipe provides a weldless and monolithic structure with superior material density. With an outer diameter of 168 mm and an extraordinary 28.0 mm wall, it is designed for critical infrastructure components.

Certified under DSTU 8938, it serves as a reliable functional analogue to EN 10216 and EN 10210 standards (3.1 + CE certified), ensuring high safety margins. The ultra-thick wall allows for its use as a premium mechanical billet for machining extremely heavy-duty bushings, rollers, and pressure vessel components. The seamless profile ensures uniform material properties along the entire section, eliminating any risks associated with weld fatigue or structural inconsistency common in welded alternatives. Steel 20 grade provides excellent ductility and reliable weldability, making it efficient for integration into steam lines.

The untreated black surface is ready for project-specific industrial insulation or custom protective painting after onsite assembly. Available for self-pickup from regional logistics hubs in Europe, Poland, and Bulgaria. Wholesale freight delivery is provided for orders starting from 1 ton. Our metal service centers offer high-precision band-saw cutting to your specific lengths.
