Heavy-duty hot-finished seamless black steel tube 159x36 is an ultra-thick-walled industrial profile manufactured from structural Steel 20 (European grade P235TR1). This weldless tube is produced through the hot deformation of high-grade solid cylindrical steel billets, ensuring a completely monolithic structure with maximum material density. With a 159 mm outer diameter and an extraordinary 36.0 mm wall, this pipe is one of the most robust hollow sections for critical infrastructure and pressure installations.

Certified under EN 10216-1 for pressure pipelines and EN 10210-2 for hot-finished structural hollow sections (3.1 + CE certified), this pipe provides absolute structural integrity and resistance to extreme hydraulic hammer impacts. The massive 36 mm wall thickness allows for its use as a specialized mechanical billet for machining extremely heavy-duty bushings and machine components. The seamless profile eliminates weld fatigue risks and split-risk under thermal expansion. P235TR1 steel offers superior ductility and weldability, essential for secure integration into high-pressure energy networks.

The untreated black surface is ready for standard industrial insulation or custom protective painting. Available for self-pickup from regional logistics centers in Europe, Poland, and Bulgaria. We support wholesale freight delivery across the EU for orders starting from 1 ton. Our centers offer professional band-saw cutting to provide specific lengths.
