G.O.N.E. Chemical 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 PIA PR 13C (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 RP 13C number and conductance shown in kD/mm are required on the screen label.
Internationally, API RP 13C is 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.
