proSTRAIGHT Straight Slotted Liner

Datasheet: [PDS-0001] [R4]

RGL developed the API certification for slotted liners, allowing us to provide the highest standards in quality, accuracy and delivery. Our innovative manufacturing methods and rigorous quality control standards provide a variety of slot configurations with precise tolerances. Based on core particle size analysis, RGL can custom design slotted liner according to specific reservoir sand distribution, optimizing sand retention and inflow/outflow distribution with various slot designs. Our extensive manufacturing capabilities ensure quick production turnaround time to meet customer demands and scheduling.

RGL’s proSTRAIGHT slotted liner has superior mechanical strength and integrity that provides a reliable, durable, and economic solution to certain reservoirs with low fines and clays contents. Finite Element Analysis ensures the load conditions are met for each application. RGL’s patented thermal deburring technology effectively deburrs the ID of the slotted liner, reducing the risk of induced pressure drop.
