Tube making lines

Protube Engineering, together with its partners, specialise in the supply of plant, machinery, parts and consumables for the tube and profile making industry. Together we have designed and realised numerous standard lines, as well as highly specialised equipment for our broad-ranging clients. Below are some of our key partners.

Tube and profile making

OTO Fives

OTO Fives has been designing, manufacturing and installing complete units for the production of welded tubes and/or profiles for over 30 years. Considered a pioneer in the high speed line production techniques, OTO Fives experience and expertise, based on more than 700 units installed all over the world, guarantee top level equipment at competitive pricing. OTO Fives traditionally manufacture mills up to 8” but have extended their production range up to 26”.

Welding &

EFD Induction

EFD Induction offers a full range of solid-state welder systems fitted with induction coils and/or contact heads. All our welders have rugged, independent full-bridge IGBT transistors. These transistors are virtually short-circuit proof, considerably boosting reliability and uptime. You also get more output thanks to our continuous electronic load matching. This secures full power output across a wide range of tube sizes (OD 3/8"-26"/10mm-600mm), ensuring maximum welding speed for each size. Moreover, you can reduce your power consumption. The efficiency from input at the rectifier to output at the coil is, at least 85-87 percent. And the use of diode rectifiers results in a high, constant power factor (0.95) at all power levels - thereby eliminating the need for costly reactive power compensation capacitors.

testing (NDT)

Prüftechnik Fluke

Eddy current testing has become one of the most important testing methods used by industry today. It can be fully integrated in production lines, whether at low or high speeds or for cool or hot metals. It provides mill operators with immediate feedback on product integrity, allowing correction of process changes before scrap develops or serious overhauls are required. Eddy current testing is easy to install and operate providing reliable test results day after day, year after year.

  • Fast, state of the art, computer based system
  • All major applications requiring 1 or 2 test coils, or rotating system
  • Extremely simple operation featuring touch screen monitor
  • Extensive signal evaluation options
  • Complete documentation of test results and statistics
  • Connection to host computer or central controlling network

Consumables & Wear Items

Protube offers a complete range of tube making consumables and wear items, many already in stock, or can supply on short notice. The products below are just a small selection in our range.

Tube forming rolls
wear items &


Forming rolls for the tube sector can be made of different materials such as special steels, sintered materials or from various other alloys. In case of high quality products, such as automotive or furniture applications, and whenever the production of a tube with tight tolerances is required, Eurolls offers solutions which foresee the use of combined materials, including solid carbide rolls in the most critical applications, or where rolls are subject to wear. Eurolls can produce roll tooling for tube/pipe up to 24”.

cut off


Protube’s Swiss cut off blades are designed for maximum performance and cut quality. The range includes SwissCUT HR friction blades (new technology) for substantially higher number of cuts (3-4 x more compared to normal friction blades), much smaller tag and less cracking. The new SwissCUT Powerblades (45 or 65) are designed for maximum performance when cutting higher grade steels (dual grade). HSS blade features an innovative coating system for tubes and bars in the range of 450N/mm2 to 650N/mm2. The SwissCUT T (TC tipped blade) completes the range. Proven performance with all major tube manufacturers!
