At Oilfield Piping Systems, We offer a comprehensive range of Centek production casing centralizer’s, Centek design and manufacture a range of revolutionary centralizers which provide unprecedented stand-off – giving optimum pipe centralization, aiding pipe rotation and easing the string to total depth without issue. Centek products are manufactured in our facilities in the UK, USA and are available in various dimensions as detailed below:
The Use of centralizers on the casing string helps operators reach total depth by supporting the casing in deviated sections and then centralizing the casing within the wellbore promoting clean out, proper fluid dynamics and ensuring quality zonal isolation.
At Oilfield Piping Systems, We offer a comprehensive range of Endurance Downhole production tubing and casing for purchase with other Accessories , available in various dimensions as detailed below:
The EndurAlloy name is trademarked by Endurance Technologies Inc.
The feature of EndurAlloy TM tubing and casing is the diffusion alloying surface engineering process which creates a hard and dense alloy on the surface of the steel substrate. This engineered surface provides excellent protection against abrasion due to rod wear above the pump, around a deviation, high sand production, and corrosion in extreme environments where failures regularly occur. These failures result in increased costs associated with frequent well workovers, well servicing, lost production, and high maintenance.
In addition, the diffusion alloyed surface has a lower coefficient of friction which improves pumpability in a well, reducing top load and side load while increasing production rates and revenue on stream.
