Abstract:
1. A test pressurisation device adapted for reception of hose, the test pressurisation device comprising: a first pair of press rolls between which the hose can be inserted, and a second pair of press rolls between which the hose can be inserted, wherein the first pair of press rolls is arranged at a distance from the second pair of press rolls, and each pair of press rolls is arranged for pressing the hose together between the rolls in conjunction with pressurisation of the hose so that a limited part of the hose located between the first and the second pair of press rolls can be held pressurised, wherein the test pressurisation device further comprises: a motorised mechanism arranged to feed the hose through the pairs of press rolls in conjunction with pressurisation of the hose to allow different parts of the hose between the first and the second pair of press rolls to be successively held under pressure, wherein at least one of the pairs of press rolls is configured to operate as driving rolls for feeding of the hose at a suitable speed while adjusting and/or maintaining a prescribed test pressure of the limited part of the hose currently located between the first pair of press rolls and the second pair of press rolls, wherein the pair of press rolls is motorised and mounted on a sled where one or both of the pair of press/driving rolls is arranged to controllably drive the hose forward or not, and wherein the other pair of press rolls is motorised and mounted in a fixed position, where one or both of the other pair of press rolls is arranged to drive the hose forward at a constant or variable speed.
