Interpret API RP 13C in the Form of Question & Answer
1.What is API RP 13C?
1.A new physical testing and labeling procedure for shale shaker screens. To be API RP 13C compliant, a screen must be tested and labeled in accordance with the new recommended practice.
2.Two tests were devised
1.D100 cut point
2.Conductance.
The tests describe a screen without predicting its performance and can be performed anywhere in the world.
1.Once we identify the cut point and conductance complying with API RP 13C, a permanent tag or label should be attached on the visible and legible position of the screen. Both cut point expressed as an API number and conductance shown in kD/mm are required on the screen label.
2.Internationally, API RP 13C is ISO 13501.
3.The new procedure is a revision of the previous API RP 13E.
2.What is D100 cut point meaning?
1.Particle size, expressed in micrometers, determined by plotting the percentage of aluminum oxide sample separated.
2.D100 is a single number determined from a prescribed laboratory procedure – the results of the procedure should yield the same value for any given screen.
3.The D100 should not be compared in any way to the D50 value used in RP13E.
3.What is conductance number meaning?
1.Conductance, permeability per unit thickness of a static (not in motion) shale shaker screen.
2.Measured in kilodarcies per millimeter (kD/mm).
3.Defines a Newtonian fluid's ability to flow through a unit area of screen in a laminar flow regime under prescribed test conditions.
4.All other factors being equal the screen with the higher conductance number should process more flow.
4.What is API screen number?
1.Number in an API system used to designate the D100 separation range of a mesh screen cloth.
2.Both mesh and mesh count are obsolete terms and have been replaced by the API screen number.
3.The term "mesh" was formerly used to refer to the number of openings (and fraction thereof) per linear inch in a screen, counted in both directions from the center of a wire.
4.The term "mesh count" was formerly used to describe the fineness of a square or rectangular mesh screen cloth, e.g. a mesh count such as 30 × 30 (or, often, 30 mesh) indicates a square mesh, while a designation such as 70 × 30 mesh indicates a rectangular mesh.
5.What does the API screen number tell us?
1.The API Screen Number corresponds to the API defined range of sizes into which the D100 value falls.
6.What does the API Screen Number Not tell us?
1.The API Screen Number is a single number which defines solids separation potential under specific test conditions.
2.It does NOT define how a screen will operate on a shaker in the field as this will depend upon several other parameters such as fluid type & properties, shaker design, operating parameters, ROP, bit type, etc.
7.What is Non-blanked Area?
1.The non-blanked area of a screen describes the net unblocked area in square feet (ft²) or square meters (m²) available to permit the passage of fluid.
8.What is the practical value of RP 13C to the end user?
1.RP 13C provides an unequivocal procedure and benchmark for comparing different screens.
2.The primary intent of RP 13C is to provide a standard measuring system for screens.
9.Should I use the old screen number or the new API Screen Number when ordering replacement screens?
1.Although some companies are changing their part numbers to reflect their conformance to RP 13C, others are not. It is therefore best to specify the RP13C value you want.
