In one of the Polish cities customer of Tubes International drills a tunnel. This tunnel will connect two city parts. The works are carried out 12 m up to 24 m deep underground thanks to a huge “mole machine”. The drill head has a diameter of about 13 meters, the length of the entire device is over one hundred meters.
We deliver all kinds of hydraulics to the construction site – 1SN, 2SN, 4SP, 4SH, R15 hoses, quick couplings, ball valves, etc. A large part of our supplies are also SHANNON DN76 concrete hoses with groove couplings and all accessories such as: clamps, gaskets, cleaning balls. The working pressure of concrete hoses is 85 bar. The lengths of supplied assembled hoses are 5m to more than 20m.
The biggest challenge in cooperation with such a customer is the reaction time. One hour of downtime for such a powerful machine costs a fortune. Therefore, if the hydraulic hose breaks, it must be replaced immediately. An additional challenge is also to maintain adequate storage protection for 3 ”concrete hoses.
It is a pleasure to consult and supply goods to such a ambitious project.
