FLUID FLOW CONDUIT, METHOD AND USE |
摘要 |
<p>The invention concerns a section of tubing or other conduit having a flow passage. The flow passage extends through the tubing and incorporates a member extending through the passage and guides which constrain a fluid flowing through the flow passage to flow around the member along a path which is longer than an axial length of the flow passage in a fluid flow direction. The guides may define an annular path. The conduit may comprise an inside wall and the guides may comprise a combination of at least one spiral channel defined along the inside wall and the member may be a sucker rod extending along the flow passage.</p> |
