Frequently Asked Questions
What is the minimum inner diameter available for standard products?
The standard inner diameter range starts from 1mm and goes up to 100mm. For applications requiring larger diameters between 100mm and 200mm, custom manufacturing is available upon request.
Can you manufacture tubes with wall thickness greater than 50mm?
Yes. While the standard wall thickness range is 0.1mm to 50mm, we offer customized production for special wall thicknesses between 50mm and 80mm to meet demanding structural or industrial requirements.
What is the maximum tube length you can produce?
Standard production lengths range from 100mm to 3000mm. For special projects, we can customize lengths up to 6000mm. We also support on-demand cutting to any specified length within these ranges.
Which international standards do your tolerance specifications follow?
Our products are manufactured in accordance with ASTM B760. Tolerances can also be customized to meet other international standards or specific customer drawing requirements, with inner/outer diameter tolerances as tight as ±0.01mm.
What is the difference between Precision Grade and Standard Grade straightness?
Precision Grade tubes achieve a straightness of ≤0.1mm per meter, making them ideal for high-accuracy assemblies and precision instruments. Standard Grade tubes have a straightness of ≤0.2mm per meter, suitable for general industrial applications.
How do I request a custom specification that is not listed in the standard range?
Simply contact our technical team with your required inner diameter, wall thickness, length, tolerance class, and any applicable standards. We will evaluate feasibility and provide a tailored solution along with a detailed quotation.
