Upgrading and rebuilding tube mill and roll forming lines

UNIVERSAL Tube & Rollform has been working on upgrading and rebuilding tube mill and roll form lines using state of the art controls, new drive systems and die accelerators from Universal Controls Group. The current economic conditions have led many companies to upgrade their tube mills or rollform lines as opposed to going to the expense buying new equipment. This is the area Universal Tube & Rollform has been expanding in over the last several years. It is uniquely qualified to assess the current condition of customers’ machinery and offer expert advice for upgrades. It works together with Universal Controls Group to assess the options customers need such as new controls, drive systems, die accelerators, length control and other accessories to retrofit existing machinery. Universal Tube can also offer complete turn- key systems from initial design to start-up. The average lead time for a reconditioned machine is 12 to 14 weeks. Customers are encouraged to bring their material to run through the machine at final inspection and are offered a ‘customer inspection and safety awareness’ programme, for communication purposes so that any operational concerns can be written down by the customer and addressed accordingly by the Universal professionals. Universal also offers one of the largest EZTM JSC has begun designing a new generation of tube-rolling plant and the principle of efficiently fragmented technological process (EFTP) forms the basis of the project. The essence of the EFTP principle is that the technological process is divided into smaller subprocesses that are used to allow the flexible development of different manufacturing processes depending on the market requirement of the finished products. The use of this principle for designing the tube-rolling plant allowed three tube rolling technological schemes to be included. This allows the production of small and large batches of tubes of a wide range of product sizes and grades with minimum expenses for the resetting of the equipment. The 7-stand continuous mill of the new generation uses MPM Quattro technology, which will be used as an elongator. Eight-

selections of used tube, pipe mills and rollforming machinery in stock that can be found anywhere in the world. Many of its in-stock lines have already been upgraded and are ready to put into production. It offer tube mills, rollformers, HF welders, straighteners, cut-offs and more. Customers can purchase machinery direct from the floor as is and the experienced team can clean, paint, rebuild, install and train staff making certain that the machine is running efficiently. Universal Tube belongs to the MDNA (Machinery Dealer’s National Association)

so you can trust that the equipment is of the highest possible quality. It also offers a 30 day return privilege if something happens and the machine would need to be repaired or returned. The company is a proud member of the TPA, FMA, SME, ITA and The Better Business Bureau. Overall, Universal’s mission is to satisfy every customer that walks through its doors.

three-high scheme; this keeps the friction processes at the inner tube surface to a minimum at the mandrel extracting by implementing the technology of increasing of tube cross-section perimeter as compared to mandrel section perimeter, similarly to MPM mill technology (the use of such technology in a three-high mill is impossible); decreasing the transverse thickness variation of the produced tubes (the technology has the potential to reach the thickness variation parameter up to the value of ±4%); the distinctive feature of the new MPM Quattro technology is that it can be applied for both building new tube-rolling plants with continuous mill and retrofitting of

This decision provided friction conditions at the outer tube surface similar to the

existing MPM mills. EZTM JSC – Russia Fax: +7 496 577 73 04 Email: protokol@eztm.ru Website: www.eztm.ru
