API RP 13C (ISO 13501)
Derrick is leading the way to API's NEW API RP 13C (ISO 13501), the new
industry standard for physical testing and labeling of shaker screens. Until RP
13C, no common standard existed for testing and labeling screens. The result?
Great disparity and performance in screens throughout the oil and gas drilling
industry. But now, API RP 13C is here. So you know exactly what you're
buying!
What is API RP 13C (ISO 13501)?
- A new physical testing and labeling procedure for shaker screens. To be
API RP 13C compliant, a screen must be tested and labeled in accordance
with the new recommended practice.
- Two tests were devised: cut point and conductance. The tests describe a
screen without predicting its performance and can be performed anywhere in
the world.
- After identifying the cut point and conductance, complying with API RP
13C requires application of a permanent tag or label to the screen in a
position that will be both visible and legible. Both cut point expressed as
an API number and conductance shown in kD/mm are required on the screen
label.
- Internationally, API RP 13C is ISO 13501.
- The new procedure is a revision of the previous API RP 13E, which was
based on optical measurements of the screen opening using a microscope and
computer analysis. Under API RP 13E, screen designations were based on
individual manufacturer test methods, producing inconsistent labeling.
