Surface Finish: Available in hot-rolled, cold-rolled, pickled, bright annealed, mechanically polished, or other surface conditions to meet specific optical, fluid purity, or corrosion resistance requirements.

End Finish: Plain Ends (PE), Beveled Ends (BE).

Manufacturing Process & Quality Control

High-Purity Melting & Tube Forming: Utilizing advanced vacuum melting (VAR/EB Melting) technology to produce high-purity zirconium ingots/billets. Subsequently, seamless zirconium tubes are manufactured through rigorously controlled tube billet preparation, extrusion, and precision cold drawing and/or cold rolling (pilgering) processes. For welded zirconium tubes, high-quality TIG/GTAW welding techniques are employed.

Precision Heat Treatment: Implementing precise annealing treatments to relieve processing stress, optimize grain structure, and ensure the material's ductility, mechanical properties, and long-term stability.

Rigorous Quality Testing (INSPECTIONS):

Raw Material Inspection: Strict chemical composition analysis (Spectro Test), including control over trace impurities.

Internal Flaw Detection: Ultrasonic Testing (UT) and Eddy Current Testing (ET) are performed on finished tubes to ensure the absence of internal cracks, inclusions, porosity, and other defects.

Geometric Dimensions & Visual Inspection: Precise measurement of OD, WT, length, ovality, straightness, and high-precision visual and automated inspection for surface (internal and external) defects.

Pressure Testing: Hydrostatic testing or pneumatic testing to verify the tube's pressure resistance and sealing integrity under operating conditions.

Mechanical Properties Testing: Tensile Test (Elongation, Yield Strength, Tensile Strength), Hardness Test, Flaring Test, Flattening Test, etc.

Metallographic Analysis: Evaluation of grain size and microstructure to ensure conformity with standards and final application requirements.

Corrosion Testing: Corrosion tests in specific corrosive media (e.g., ASTM G28, G48) are performed to verify durability in harsh chemical environments.

Nuclear-Grade Performance Testing: (If supplying nuclear-grade zirconium) Low thermal neutron capture cross-section testing can be performed.

Traceability: Comprehensive material reports are provided, ensuring complete traceability from raw material to final pipe/tube, with support for independent third-party certification.
