Abstract

Pump plug (1) for flowline operations, which pump plug (1) comprises a resilient body (2) and a flexible cage (3) having a wear-resistant outer surface (4) arranged around the resilient body (2), wherein the flexible cag e (3) comprises a tube having a first end (6) and a second end (7), which tube is provided with a number of slits closed (16) at at least one end.

Claims (5)

1. Pump plug for flowline operations, which pump plug comprises a resilient body and a flexible cage having a wear-resistant outer surface arranged around the resilient body, wherein the flexible cage comprises a tube having a first end and a second end, which tube is provided with a repeating pattern of slits closed at at least one end.
2. Pump plug as claimed in claim 1, wherein the repeating pattern comprises two slits, a first slit that is closed at the first end of the tube and open at the second end and a second slit that is closed at the second end of the tube and open at the first end.
3. Pump plug as claimed in claim 1, wherein the repeating pattern comprises a first, second and third slit, wherein the first slit is closed at both ends of the tube, wherein the third slit is aligned with the second slit, and wherein the second and third slit are open at opposite ends of the tube and closed in the middle of the tube.
4. Pump plug as claimed in claim 3, wherein the repeating pattern is extended in axial direction with its mirror image.
5. Pump plug as claimed in any one of the claims 1-4, wherein the resilient body comprises a rigid core and a mantle of resilient material fixed on the outer surface of the rigid core.
