An apparatus (50) is provided for use in internal cleaning of at least one pipe (10), which apparatus (50) is arranged for connection to a first pipe end (14) of the at least one pipe (10) and to a second pipe end (15) of the at least one pipe, wherein the apparatus (50) at least comprises a coupling device designed for connection to a reservoir of pressurised gas, a pressure chamber (20) for introduction of cleaning pigs (21) and a pig receiver (23) for receiving cleaning pigs (21) which have passed through the at least one pipe (10). The apparatus (50) further comprises a pressure booster (29) for pressurising a liquid fluid and at least one valve means (16,17) so as to allow a cleaning pig (21) to be driven through the at least one pipe (10) by means of either the pressurised gas or the pressurised liquid fluid.
An apparatus (50) for use in internal cleaning of at least one pipe (10), which apparatus (50) is arranged for connection to a first pipe end (14) of the at least one pipe (10) and to a second pipe end (15) of the at least one pipe, the apparatus (50) at least comprising a coupling device designed for connection to a reservoir of a pressurised gas, a pressure chamber (20) for introduction of cleaning pigs (21) and a pig receiver (23) for receiving cleaning pigs (21) that have passed through the at least one pipe (10), characterised in that the apparatus (50) further comprises a pressure booster (29) for pressurising a liquid fluid and at least one valve means (16,17) so as to allow a cleaning pig (21) to be driven through the at least one pipe (10) with the aid of either the pressurised gas or the pressurised liquid fluid.
A method for cleaning at least one pipe (10) wherein an apparatus (50) is used that is connected to the first pipe end (14) and second pipe end (15) of the at least one pipe (10), which apparatus (50) at least comprises a coupling device for connection to a reservoir of pressurised gas, a pressure chamber (20) for introduction of cleaning pigs (21), a pig receiver (23) for receiving cleaning pigs (21) that are sent through the at least one pipe (10), and a pressure booster (29) for pressurising a liquid fluid, characterised in that during the cleaning of the at least one pipe (10), the following steps are carried out:
A method for cleaning and verifying the cleanliness of at least one pipe (10) wherein an apparatus (50) is used that is connected to the first pipe end (14) and second pipe end (15) of the at least one pipe (10), which apparatus (50) at least comprises a coupling device designed for connection to a reservoir of pressurised gas, a pressure chamber (21) for introduction of cleaning pigs (21), a pig receiver (23) for receiving cleaning pigs (21) that are sent through the at least one pipe (10), a pressure booster (29) for pressurising a liquid fluid, and a sampler (26) which can take samples of the liquid fluid after it has flowed through the at least one pipe (10), characterised in that during the cleaning and verification of the cleanliness of the pipe, the following steps are carried out:
