Product Overview

BELNADE delivers elite-grade piping solutions designed for the world’s most demanding process industries. Our portfolio covers both seamless (SMLS) pipes for extreme high-pressure applications and welded (WELD) configurations for large-diameter fluid transportation. Manufactured under rigorous quality controls, BELNADE tubes ensure leak-free performance and long-term structural reliability.

Standard Sizes & Specifications

Manufacturing Process

Seamless pipes are produced via hot extrusion and cold pilgering or drawing without any longitudinal weld seams, ensuring maximum structural integrity under high pressure and temperature. Welded pipes are formed continuously from precision-slit plates or sheets using advanced ERW, EFW, or LSAW techniques, followed by automated TIG/plasma welding and full solution annealing.

Available Alloy Grades

We offer pipes & tubes in the nickel alloy grades listed in the left-hand navigation.

Industrial Applications

Oil & gas upstream extraction, sour gas service, and umbilical tubing

Chemical and petrochemical tubular heat exchangers, condensers, and piping headers

Nuclear power generation auxiliary cooling loops

Pharmaceutical and fine chemical fluid transport lines

Quality Control and Testing

All BELNADE pipes and tubes undergo rigorous non-destructive testing (NDT), including eddy current inspection, hydrostatic pressure testing, and X-ray radiograph examination (for welded pipes). Dimensional tolerances, ovality, wall thickness uniformity, and mechanical tensile/flattening tests are performed strictly in accordance with ASTM standards.

Packaging and Export

Pipes and tubes are supplied with plastic protective caps on both ends to protect bevelled or threaded edges. Bundles are secured with durable strapping, wrapped in protective woven fabric or plastic film, and packed into secure wooden crates or containers to ensure damage-free transit.
