Industrial heavy-duty seamless black steel pipe 180x40 is a specialized hollow section designed for the most critical high-pressure and structural engineering tasks. Manufactured from premium quality structural steel grade 20 (equivalent to P235TR1) through a seamless hot deformation process, it ensures absolute material purity and structural density. With a 180 mm outer diameter and an ultra-reinforced 40.0 mm wall, this pipe acts as a nearly-solid cylindrical component with a massive safety factor against internal rupture and mechanical failure.

Certified under international standards EN 10216-1 and EN 10210-2 (3.1 + CE), this product is a reliable solution for critical infrastructure. The 40 mm wall thickness makes it an ideal raw material for the precision machining of ultra-heavy hydraulic cylinders, high-pressure steam headers, and primary structural support nodes in heavy machinery. The absence of any weld seams provides isotropic strength and prevents leakage under extreme vibration. The P235TR1 grade is favored for its excellent mechanical ductility and superior weldability, simplifying integration into complex engineering systems.

The untreated black surface is ready for project-specific industrial coatings or anti-corrosive insulation. We maintain stock of this heavy profile for prompt delivery from our logistics centers in Europe, specifically Poland and Bulgaria. Wholesale freight terms are available for bulk orders starting from 1 ton. Our service centers offer professional high-precision band-saw cutting to provide specific lengths tailored to your project requirements.
