Structural Types & Formats
Seamless Pipes & Tubes
Manufactured via hot extrusion or cold drawing with zero welded seams. Engineered specifically for extreme hydraulic pressure, thermal cycling, and critical process environments.
ERW & Welded Pipes
Produced from high-strength metal strips rolled and welded longitudinally. High surface accuracy and uniform wall thickness ideal for water lines, structural supports, and low-to-medium pressure pipelines.
Instrumentation Tubes
Highly calibrated, thin-walled capillary tubes designed for control panels, analytical equipment, and hydraulic control systems where micro-tolerances are critical.
Coiled & U-Bend Tubes
Custom-bent and continuous coiled tubing configurations optimized for boilers, condensers, heat exchangers, and space-constrained subsea processing modules.
