Galvanized steel pipes with Robur quick couplings

In the 50s the famous Italian firm Mellini and Martignoni starts to distribute its quick joint for irrigation, which is now very well received by the agricultural holdings in Europe, Africa and South America. Subsequently, all the the joint Mellini rights were acquired by Giunti SpA, which renames it Robur. Today the name Robur has spread to over 40 countries, and thanks to its high performance in pressure resistance is extremely modern and competitive. Despite having a wide field of applications the Robur joint is particularly appreciated in systems using irrigation machines. Pressure resistance is fully compatible with the working pressures of self-propelled machines. The range of items produced is as complete as possible, also different elements can be made to specific customer requirements

Description

REVIEW: Made of certified DC01steel, pipes are drawn in our workshops and soldered using automatic machines. Items are cut according to customers requirements and then are subjected to the Tightness test pressure on CNC testing facilities. The joints are printed from DD11 pickled steel by molds with mechanical presses up to 500 tons. Robot welders provide for the welding by inverter generators. The galvanization process is preceded by a salt bath in order to eliminate any possible superficial impurity contained in the product. Vertical galvanizing well is probably the only one in Europe and it is specifically designed for thin-walled pipes galvanizing – in service 24 hours a day, 365 days a year – with its 458 ° C operating temperature, provides an optimal grip of the mixture of zinc on the steel bottom. Another distinctive feature of the quality of the protective treatment is the use of virgin electrolytic zinc which purity is certified at 99.995%.
