Dual-capacity, high frequency tube mill T&H LEMONT has delivered a new dual-capacity quick-change tube mill system, developed to handle increasing demands for JIT deliveries of welded tubular products. The dual-capacity mill will allow for a greater range of production diameters in a minimum amount of floor space. producing tubing from 1.25" to 5", and a second set of subplates with 6" shafts was designed to produce tubing from 2.5" to 8" diameter. The distance between the stands is optimised for the diameter of tubing produced on each set of subplates. Complete line for precision steel tubes TUBE mill equipment supplier ASMAG has shipped a complete line to manufacture up to 4" high-precision steel tubes to a customer in the USA. The comprehensive line comprises a fully automated 600kN triple draw bench with integrated pointing machine, and a fully automated finishing line consisting of a ten-roll straightener RRM-pro-100/10, testing table, multiple sawing line, chamfering units and a stacking, bundling and banding system. The requirements of the line were to achieve savings on production costs and a simultaneous increase in quality of the products made. Modern drive technology and innovative machinery concepts in addition to a high degree of automation allow for faster production speed and higher availability of the line. The placement of all equipment in-line and the resulting elimination of manual material handling between the individual components of the line resulted in significant reduction of scrap. The customer benefits from ASMAG’s quality and consistent manufacturing standards, a single point of contact, and Quick-change tech for mills and roll forming RAFTER Equipment Corporation has introduced a new patented Mill-Flip ® quick-change technology for tube mill and roll forming machines that promises part- to-part changeovers in 15 minutes or less. The new system requires no special mill stands or roll tooling, no complicated mill drive connections or electrical controls systems, no special operator or maintenance training, and no overhead cranes or special raft handling equipment. It features the ability to quickly break into a production run and quickly go back to the previous product, as well as built-in redundancy for increased line up-time, and no infringement on the operator’s side of the mill during changeovers. The company also manufactures tube mills, pipe mills, roll forming machines, flying cut-offs and other related mill machinery. Its business includes the retrofit and replacement of common tube mill components, including driven roll stands, idle side roll stands, weld squeeze boxes, weld upset bead removal equipment (OD bead trimmers) and turkshead type straighteners.

products, high-strength welded and roll-formed shapes and large diameter API pipe. In addition to complete production systems, the company provides a variety of components and services to the tube, pipe and roll-forming industries. Services include tube and pipe roll design and manufacturing, mill alignment and operational consulting. Components offered by T&H Lemont include welders, cut-offs, entry equipment, accumulators, pre- punch, post-punch, seam orientation stands, weld boxes, edge conditioners, bead scarfing systems, straightening systems, single point adjustment systems, dedimplers, blades, jaws and roll shafts.

As with all quick-change systems, one set of subplates is in production while the second set of subplates is available for change-over. The mill, which produces standard mechanical rounds as well as hollow structural shapes, is designed to utilise the customer’s overhead crane to change over the subplates. The subplates are held to the base by a hydraulic clamping system, allowing them to be connected and disconnected from the base quickly and efficiently. T&H Lemont has provided technologies to produce products such as stainless steel hypodermic needles, communication cables, flexible tubular

In effect, the dual-capacity mill gives the tubing producer the ability to produce a range of tubing normally produced on two mills. It also represents a smaller initial investment to produce a larger range of tubing diameters. The entire entry and exit equipment remains unchanged, as does the basic mill base and drive system. The dual capacity of the mill is achieved by two sets of quick-change subplates designed to mount on a single base system and utilise one drive system. In this instance, one set of subplates with 3.5" shafts was designed for
