Ritmo ALFA 400 CTB fitting fabrication welder (110-400mm)

The Ritmo ALFA 400 CTB is a workshop butt-fusion welding machine designed to fabricate fittings by joining HDPE pipe segments, with the help of special jaws. It can produce elbows Ø 110-400 mm and tees, crosses and wyes Ø 110 ÷ 355 mm. Elbows and wyes (Y) jaws opening/closing and locking movements are controlled hydraulically. Tees/crosses jaws opening/closing movements are manual.


– A machine body with two hydraulically controlled carriages; a control panel that features the Easy Life system, which enables the whole welding cycle to be simple, intuitive and repeatable
– An built-in memory allows the machine to store 400 welding cycles (including the set diameters and SDR). It is possible to transfer the welding data to a PC through a serial port (USB adaptor connector available) and data-management software. A printer can be connected to the serial port, to get a welding report at the end of each welding cycle
– A Teflon-coated heating plate with hydraulic movement (in / out) on spherical bearings guides
– A milling cutter with hydraulic movement (in/out) on spherical bearings guides, operated by an electrical engine, provided with eight steel blades
– An upper cylinder, to be positioned on the jaws, for welding extra thick pipes and/or whenever it’s necessary to use high pressures
