Manufactured without welding joints, ensuring maximum structural integrity and pressure resistance.
Cost-effective solution for less critical applications while maintaining excellent corrosion resistance and dimensional accuracy.
Each alloy is engineered for specific service conditions, ranging from seawater corrosion resistance to high-temperature oxidation performance.
We ensure tight dimensional tolerances, uniform wall thickness, and high-quality surface finishes, including:
| Outer Diameter (OD) | 6 mm – 762 mm |
| Wall Thickness (WT) | 0.5 mm – 50 mm |
| Length | Random or customized |
| Processing Services | Cutting, bending, machining available |
Custom sizes and specifications are fully supported to meet specific project requirements across various industries.
Our nickel alloy tubes are manufactured in strict accordance with internationally recognized standards to ensure consistent quality, performance, and compliance.
ASTM B163 / B165 / B167 / B444 / B407
ASME SB Series
DIN / EN
JIS
Example: ASTM B444 specifies the requirements for nickel-chromium alloy seamless pipes and tubes, including mechanical properties, chemical composition, and inspection standards, ensuring reliable performance in critical applications.
TSM Technology operates advanced production facilities with full-process control:


Raw Fabric Arrangement: High-purity nickel, chromium, and molybdenum are carefully chosen and analyzed.
Melting: Vacuum acceptance dissolving makes homogeneous amalgam composition with negligible impurities.
Forging: Hot producing shapes the ingot into rounds reasonable for pipe production.
Hot Puncturing: Warmed rounds are penetrated to make empty shells utilizing rotational penetrating mills.
Elongation: Pilgering or tube rolling amplifies the shell to the desired length and divider thickness.
Heat Treatment: Arrangement tempering at 1150°C followed by fast cooling optimizes mechanical properties.
Finishing: Pickling evacuates surface oxides, and the last measuring guarantees dimensional accuracy.
Inspection: Comprehensive testing counting ultrasonic, whirlpool current, and hydrostatic testing.

To ensure product quality, TSM Technology conducts the following self-inspections on manufactured seamless pipes. Here's a table summarizing the main testing requirements for seamless tubes under ASTM B338, to ensure that the products meet both applicable standards and customer requirements.
