Key Features of BENKOO METAL Tubes:
Superior Material Integrity: Seamless construction ensures uniform structure and enhanced pressure-bearing capability, free from longitudinal welds.
Precision Dimensional Control: Guaranteed tolerances on outer diameter (OD), wall thickness (WT), and ovality for optimal fit and performance in tube sheets.
Optimized for Service: Materials are selected and processed (e.g., heat treatment, finishing) to deliver specific properties like creep strength (for boilers) or corrosion resistance (for exchangers).
Full Certification: Supplied with complete Mill Test Certificates (MTC) and traceability to meet code compliance (ASME, PED).
