Apparatus and methods for an erosion control coating on an interior surface of production equipment
A technique for reducing erosion on the interior of a production component of a well system involves coating the interior of the production component with a series of ribs and grooves. The coating can be a non-metallic material in which the ribs and grooves are formed. The coating can also be applied as a series of ribs that are attached to the interior surface of the production component. The series of ribs can be made of alternating materials that have a different hardness causing the ribs to wear at different rates.
1 . A method of coating a piping or production component for conveying a fluid stream, wherein the fluid stream flows in a flow direction within the piping or production component, the method comprising:
applying a first plurality of ribs to a wall of the piping or production component, the wall having an interior surface and comprising a base material, the wall of the piping or production component having a shape that contains the fluid stream flowing in the flow direction, wherein the first plurality of ribs extend circumferentially along the interior surface and crosswise to the flow direction; and
applying a second plurality of ribs to the wall of the piping or production component, wherein the first plurality of ribs and the second plurality of ribs are applied to the wall to produce an alternating pattern wherein each of the second plurality of ribs is adjacent to one of the first plurality of ribs, wherein the second plurality of ribs extend circumferentially along the interior surface and crosswise to the flow direction,
wherein the first plurality of ribs and the second plurality of ribs form a plurality of grooves with each of the plurality of grooves disposed between one of the first plurality of ribs and one of the second plurality of ribs, wherein the plurality of grooves extend circumferentially along the interior surface and crosswise to the flow direction, and
wherein the first plurality of ribs comprises a first material and the second plurality of ribs comprises a second material, the second material being different from the first material.
2 . The method of claim 1 , wherein the first material has a different hardness relative to the second material producing different wear rates between the first material and the second material.
3 . The method of claim 1 ,
wherein each of the plurality of grooves has an average maximum depth and each of the first plurality of ribs and the second plurality of ribs has an average maximum width, and
wherein the average maximum depth of the plurality of grooves is in the range of 1-3 millimeters and the average maximum width of the first plurality of ribs and the second plurality of ribs is in the range of 1-3 millimeters.
4 . The method of claim 1 , wherein the first plurality of ribs and the second plurality of ribs are applied by a cladding machine in an alternating manner wherein during a first pass of the cladding machine one of the first plurality of ribs is applied and during a second pass of the cladding machine one of the second plurality of ribs is applied.
5 . The method of claim 1 , wherein the first plurality of ribs and the second plurality of ribs are applied by a dual feed cladding machine that applies one of the first plurality of ribs and one of the second plurality of ribs during a single pass.
6 . A piping or production component for conveying a fluid stream, wherein the fluid stream flows in a flow direction within the piping or production component, the piping or production component comprising:
a wall of the piping or production component, the wall comprising a base material and having an interior surface, the wall of the piping or production component having a shape that contains the fluid stream flowing in the flow direction;
a first plurality of ribs attached to the interior surface of the wall of the piping or production component, wherein the first plurality of ribs extend circumferentially along the interior surface and crosswise to the flow direction; and
a second plurality of ribs attached to the interior surface of the wall of the piping or production component, wherein the second plurality of ribs extend circumferentially along the interior surface and crosswise to the flow direction, wherein the first plurality of ribs and the second plurality of ribs are attached to the wall in an alternating pattern wherein each of the second plurality of ribs is adjacent to one of the first plurality of ribs,
wherein the first plurality of ribs and the second plurality of ribs form a plurality of grooves with each of the plurality of grooves disposed between one of the first plurality of ribs and one of the second plurality of ribs, wherein the plurality of grooves extend circumferentially along the interior surface and crosswise to the flow direction, and
wherein the first plurality of ribs comprises a first material and the second plurality of ribs comprises a second material, the second material being different from the first material.
7 . The piping or production component of claim 6 , wherein the first material has a different hardness relative to the second material producing different wear rates between the first material and the second material.
8 . The piping or production component of claim 6 ,
wherein each of the plurality of grooves has an average maximum depth and each of the first plurality of ribs and the second plurality of ribs has an average maximum width, and
wherein the average maximum depth of the plurality of grooves is in the range of 1-3 millimeters and the average maximum width of the first plurality of ribs and the second plurality of ribs is in the range of 1-3 millimeters.
9 . The piping or production component of claim 6 , wherein the first plurality of ribs and the second plurality of ribs are applied by a cladding machine in an alternating manner wherein during a first pass of the cladding machine one of the first plurality of ribs is applied and during a second pass of the cladding machine one of the second plurality of ribs is applied.
10 . The piping or production component of claim 6 , wherein the first plurality of ribs and the second plurality of ribs are applied by a dual feed cladding machine that applies one of the first plurality of ribs and one of the second plurality of ribs during a single pass.
