High-precision seamless hot-finished black steel tube 48.3x5.6 is a specialized hollow section engineered for pressure systems and heat exchange applications. Manufactured from premium structural steel grades P235GHTC1, P235TR2, or S235JRH through the hot rolling of solid cylindrical billets, this pipe provides a completely weldless and monolithic structure. With an outer diameter of 48.3 mm and a reinforced 5.6 mm wall, it offers an exceptional safety factor against internal pressure relative to its compact size.

The product is certified under EN 10216-1/2 for pressure and boiler pipelines and EN 10210-2 for structural sections (3.1 + CE certified). The reinforced wall thickness makes it an ideal choice for constructing high-pressure steam lines, boiler collectors, and hydraulic distribution networks. The seamless technology ensures absolute leak resistance and isotropic mechanical strength, preventing failure during rapid thermal expansion or pressure spikes. The P235GH grade is specifically designed for elevated temperature service, providing reliable long-term performance.

The untreated black surface is ready for project-specific industrial coatings or anti-corrosive insulation. We offer prompt self-pickup from regional logistics centers in Poland, Bulgaria, and Ukraine. Wholesale freight delivery is provided for orders starting from 1 ton. Our metal service centers offer high-precision band-saw cutting to provide pieces of specific lengths tailored to your project.
