The high precision seamless tubes manufactured at Fine Tubes begin their journey as seamless tube extrusions, in a range of different sizes.

This material is reduced in size several times until it gradually reaches the exact specifications our customers require. Each time we perform a reduction process, the tube needs to be cut, cleaned and heat treated before the next one can commence.

Seamless Processes

The main processes we use when manufacturing seamless tubes are tube reduction (or pilgering) and cold drawing. Other important processes in between or after the drawing process are:

Degreasing / cleaning

Straightening

NDT testing

Packaging

Annealing

Cutting to length / deburring

Printing

Shipment

Optional processes include:

Polishing

Electropolishing

Advantages

Seamless tubes offer the assurance of a completely uniform structure and are manufactured from an extensive range of materials derived from extrusions or bars. They are made to a broad range of sizes and specifications, with thick or thin walls, and can be made in small or large quantities.
