Seamless hot-rolled ultra-heavy-walled tube 51x8.8 (P355NHTC1, S355J2H) is a top-tier profile designed for extreme pressure safety and maximum structural resilience. Achieving a wall thickness of 8.8 mm on a 51 mm diameter makes it one of the sturdiest profiles available in this size range, capable of withstanding immense crushing and bursting forces.

Manufactured through the hot deformation of monolithic billets, it guarantees absolute uniformity and structural strength. The pipe is made from premium fine-grained steel grades P355NHTC1 and S355J2H, ensuring superior structural safety even under sub-zero temperatures. It is verified under both EN 10216 and EN 10210 standards for high-load engineering.

Primary applications include high-pressure hydraulic lines, offshore structural supports, and heavy machinery frameworks. Due to its massive wall thickness, the tube serves as an ideal durable billet for high-precision mechanical turning of rings and bushings. The weldless design prevents pressure failure and ensures total reliability during operation.
