Abstract

A device in connection with a separator for cleaning or reaming such a separator. The separator includes a tank or a body ( 2 ) with an inlet and at least one outlet ( 5, 6 ). A transport pipeline ( 3 ) is connected to the inlet for the supply of fluid that is to be separated in the separator. The transport pipeline ( 3 ) extends from the inlet through the separator body ( 2 ). Part ( 6 ) of the line that is located inside the separator body ( 2 ) is provided with perforations or slits ( 7 ) so that fluid that arrives in the transport pipeline ( 3 ) flows into the tank through the perforations/slits ( 7 ). Mechanical equipment for cleaning the transport pipeline ( 3 ) is designed to be sent from a magazine through the separator body ( 2 ) and on via a pipe loop back to the magazine.

Claims (9)

1. An apparatus for separating fluids, the apparatus comprising:

a separator tank or body having an inlet and at least one outlet; and

a transport pipeline connected to the inlet for the supply of the fluids that are to be separated in the separator tank or body,

wherein the transport pipeline extends from the inlet of the separator tank or body completely through the separator tank or body, and the part of the pipeline that is located inside the separator tank or body is provided with perforations or slits arranged so that fluid that arrives in the transport pipeline can flow into the separator tank or body through the perforations or slits.

2. An apparatus as claimed in claim 1 , wherein the transport pipeline is provided with a valve disposed downstream of the separator tank or body.

3. An apparatus as claimed in claim 2 , further comprising a magazine for sending mechanical equipment for cleaning the transport pipeline from the magazine through the separator tank or body and on via a pipe loop back to the magazine.

4. An apparatus as claimed in claim 1 , further comprising a magazine for sending mechanical equipment for cleaning the transport pipeline from the magazine through the separator tank or body and on via a pipe loop back to the magazine.

5. A method of cleaning the apparatus as claimed in claim 1 , comprising sending mechanical equipment through the transport pipeline to clean the transport pipeline.

6. A method as claimed in claim 5 , further comprising sending the mechanical equipment from a magazine through the transport pipeline in the separator tank or body and on via a pipe loop back to the magazine.
