Prefabricated Tube Blanks for Industrial applications are semi-finished cylindrical components designed to serve as the foundation for various tubular products in manufacturing. These tube blanks are manufactured to precise dimensional specifications, reducing the need for extensive post-processing and enabling efficient downstream fabrication. Available in a wide range of materials—including carbon steel, stainless steel (304, 316), aluminum, copper, and exotic alloys like Inconel—our tube blanks are produced using seamless or welded processes, depending on application requirements.
Manufactured through cold drawing, hot rolling, or extrusion, each tube blank features uniform wall thickness, consistent outer diameter, and smooth internal surfaces. Sizes range from small-diameter tubes (6mm OD) for precision instruments to large industrial pipes (up to 1200mm OD) for structural applications. Pre-finished options include deburred ends, chamfered edges, and pre-cut lengths, eliminating the need for initial machining steps and saving valuable production time.
Precision Dimensions: All tube blanks are manufactured to tight tolerances (OD: ±0.05mm for small sizes, ±0.2% for large diameters), ensuring compatibility with standard fittings and machining equipment.
Material Consistency: Strict quality control during casting and forming processes guarantees uniform mechanical properties, such as tensile strength and ductility, throughout the tube length.
Surface Finish: Internal and external surfaces are treated to minimize roughness (Ra ≤ 1.6μm for most grades), reducing friction and facilitating subsequent coating or plating operations.
Process Efficiency: By providing pre-cut, deburred blanks, we help clients eliminate raw material waste and reduce setup time for processes like bending, flaring, or threading.
Customizable Options: While we offer standard sizes and materials, we also provide tailored solutions for special lengths, wall thicknesses, and material compositions to meet unique project needs.
Pipeline Systems: Prefabricated stainless steel tube blanks for chemical processing plants, ensuring corrosion resistance and high-pressure tolerance.
Mechanical Engineering: Aluminum alloy tube blanks for lightweight structural components in automotive frames and aerospace assemblies.
Heat Exchangers: Copper tube blanks with enhanced thermal conductivity for use in refrigeration systems and industrial cooling units.
Fluid Handling: Seamless carbon steel blanks for hydraulic lines in heavy machinery, capable of withstanding high-pressure fluid transmission.
Architectural Applications: Decorative stainless steel tube blanks for building facades and interior design, combining aesthetic appeal with structural integrity.
Q: What is the difference between seamless and welded tube blanks?
A: Seamless tubes are formed from a single billet, offering superior strength and pressure resistance, while welded tubes are made from flat sheets and are more cost-effective for non-critical applications.
Q: Can you supply tube blanks with specific certifications?
A: Yes, we provide materials compliant with ASTM, ASME, EN, and other international standards, along with mill test certificates upon request.
Q: Do you offer pre-machined ends (e.g., beveled or threaded)?
A: Yes, we offer additional machining services to prepare tube ends for specific connections, such as butt-welding or fitting installation.
Q: What is the maximum length you can supply?
A: Standard lengths range from 1m to 12m, but we can produce custom lengths up to 18m depending on the material and diameter.
Q: How do you ensure straightness in long tube blanks?
A: All tubes undergo straightening processes and are inspected using laser alignment systems to ensure straightness within 0.5mm/m.
