Abstract
A system for transporting corrosive or erosive fluids having a flow conduit or flow equipment with a flow bore. One or more inserts (50) are disposed within the flow bore of the flow conduit or flow equipment. The insert(s) (50) include an internal structure (52) and an erosion or corrosion resistant coating (54) disposed around the internal structure. The insert(s) (50) is/are disposed inside the flow bore and provide erosion and/or corrosion resistance.
Claims17
A system for transporting corrosive or erosive fluids, the system comprising:
- a flow conduit or flow equipment comprising at least two flow bores perpendicular to each other;
- an insert disposed within each flow bore of the at least two flow bores, each insert comprising:
- an internal structure;
- and
- an erosion or corrosion resistant coating disposed around the internal structure,
- wherein the internal structure axially extends from a first end surface at a first end of the insert to a distance away from a second end surface at a second end of the insert to form an unsupported end without the internal structure at the second end;
- wherein each insert is disposed inside each flow bore of the at least two flow bores and provides erosion and/or corrosion resistance,
- wherein the internal structure is entirely within each flow bore of the at least two flow bores.
An insert for providing corrosion and erosion resistance to flow equipment, the insert comprising:
- an internal structural component that is sized to fit entirely within a flow bore of the flow equipment;
- and
- an erosion-resistant coating disposed around the internal structural component,
- wherein the internal structure axially extends from a first end surface at a first end of the insert to a distance away from a second end surface at a second end of the insert to form an unsupported end without the internal structure at the second end, and
- wherein the unsupported end comprises a section configured to form a seal along one or more respective interfaces formed between the insert and a respective portion of a second complementary insert perpendicular to the insert.
