  • Q10. I need 1m or tubing, can you sell it to me?

    No. We manufacture at an industrial scale and have minimum order charges. Unfortunately we aren’t able to offer our off-cuts for sale. Spare quantities are passed on to our customers, or we recycle the materials and use them in new projects.

  • Q11. What is your minimum order quantity?

    Minimum order sizes depend on various factors including the availability of raw materials and the size of the finished tubing you require. Our minimum order fee is £10,000 or € 12,000 which covers machine set-up, raw materials and tooling costs.

  • Q12. Do you hold stock of finished tubes?


    No, we manufacture to order. However for customers with long-term contracts we can ensure that a steady supply is maintained by making sure safety or buffer stocks are available.

  • Q13. What is your typical lead time?

    The availability of raw materials, how busy our plant is, the amount and length of tubes required and the technical specification of your order all play a role in determining how quickly we can deliver. A typical lead time is 10 to 12 weeks, but in some instances our turnaround can be as little as three weeks.

  • Q14. Can you manufacture tubes in non-standard specifications or sizes?

    Yes, our technical teams can review the specifications and application of the tubes you require. We develop and test solutions that add to existing international specifications in various industries as well as creating tubes intended for use in entirely new areas.

  • Q33. How should I specify my tube requirements?

    When you speak with our sales team they’ll discuss your requirements with you and ask if you have the UNS number or specifications of the tubing you need. We consider parameters such as the material being used, Outside Diameter (OD) by Inside Diameter (ID) in mm or inches or OD by wall thickness in mm or inches, the length of tubes, the quantity required, whether seamless or welded, as a straight length or coiled, and further quality, testing or finishing specifications.

  • Q34. Do you hot work tubes?

    All tube reduction operations are performed cold, thus maximising the potential for microstructure and hence mechanical property control.

  • Q35. What form do you supply tubes in?


    We supply tubes as straight lengths or coils.

  • Q36. How do you make tubes at Fine Tubes?

    They’re made using drawing, cold working and reduction techniques as well as using premium flat strip stock, which is roll formed to precise dimensions and then fused together with a laser. Subsequent drawing and cold working will 'sink' this welded stock to the desired dimensions. Both processes are used to deliver absolute performance.

  • Q37. What is the difference between a welded and a seamless tube?

    A seamless tube is extruded and drawn from a billet while a welded tube is produced from a strip that is roll formed and welded to produce a tube. A welded tube is less expensive than seamless tube and is readily available in long continuous lengths.

  • Q38. What materials do make your tubes in?

    We specialise in stainless steel, nickel alloys, titanium, super duplex, duplex and zirconium metals. At the moment we are unable to offer products in materials other than these.

  • Q39. How are tubes tested?

    Our tubes can be tested in a variety of destructive and non-destructive ways including eddy current, ultra sonic and pressure testing. For more information of our testing procedures please see our Quality testing page or contact Rob Eatwell on our quality assurance team.

  • Q40. Where do you get your raw materials?

    Our raw material sources are fully audited, tested and approved before use. We take a quality-first approach, keeping in mind that manufacturing advances around the world will, in time, bring further benefits for our customers.

  • Q41. What packaging do you ship the tubes in?

    We mainly supply our tubing in wooden crates with protective caps placed on either end of the tubes, and always ensure our packaging is sufficient to protect the product during storage and transit.

  • Q42. Do you bend tubes?


    We do not bend tubes, but regularly outsource this to a third party company.

  • Q43. Can I order tube samples?

    Yes, you can order samples from our sales team. Depending on the quantity and material required this could be subject to a small fee.

  • Q44. What does cannulated mean?

    Something that is cannulated means "affords a passage through its interior length for wire, thread, etc". An example would be a cannulated suture needle.

  • Q45. What are the Fine Tubes Terms & Conditions of Sale and Terms & Conditions of Purchase?
