About RTM Welding
RTM Welding, a division of RTM BV, has specialized for more than 25 years in the design, fabrication and installation of plastic tanks and piping systems. In the workshop in Bad Bentheim, plastic tanks made of HDPE or PP sheets as well as custom-made industrial wound pipes are manufactured. The piping systems are used for the transport of gas, water, air and slurry as well as for cable protection. In addition to the complete plastic welding service, the service portfolio includes the supply of pipes and fittings as well as project and construction management. The certified welding specialists carry out plastic welding work directly on site throughout Europe, both independently and under customer supervision. A key focus is the biogas industry; FTTH and FTTx fiber optic projects as well as blowing installation technology are also offered. Production ranges from one-off pieces to large series on a modern machine park.
