Hot-finished seamless black steel tube 159x25 is an exceptionally rigid industrial pipe designed for high-pressure fluid transportation and massive mechanical loading. Manufactured from structural Steel 20 (European grade P235TR1) through the hot deformation of monolithic cylindrical billets, this weldless profile features an ultra-thick 25.0 mm wall and an outer diameter of 159 mm. The monolithic construction ensures absolute material density and structural integrity, delivering a massive safety factor for critical infrastructure.

The product is dual-certified under EN 10216-1 for pressure systems and EN 10210-2 for load-bearing structural hollow sections (3.1 + CE certified). The extra-thick wall makes it an ideal starting material for hydraulic cylinder bodies, high-pressure steam headers, and heavy support columns in large-scale architecture. Unlike welded tubes, this seamless profile is resistant to thermal expansion stresses and vibration fatigue. The P235TR1 grade ensures excellent ductility and superior weldability, making it efficient for integration into complex engineering networks.

The untreated black surface is suitable for project-specific industrial coatings. We offer self-pickup from logistics hubs in Europe, Poland, and Bulgaria. Bulk freight delivery is provided for orders starting from 1 ton. Our metal centers offer professional band-saw cutting for precise length requirements.
