The 0SO slip-on stop collars are a reliable and economical choice for securing centralizers on casing in less challenging well conditions.
The 0SO slip-on stop collars are a reliable and economical choice for securing centralizers on casing in less challenging well conditions.
Designed to support primary cementing, these stop collars ensure centralizers remain securely in place during casing operations. The set screw design offers high holding forces while minimizing damage to wellbore tubulars, making the 0SO an efficient and effective solution for maintaining well integrity.
Tailored to complement Centek’s Level 2 centralizers, the 0SO stop collars are ideal for standard casing grades and applications in less demanding wellbore sections. Key features include anti-vibration screw retention to ensure consistent performance and Centek QA for quality assurance. This makes the 0SO stop collar an excellent choice for operators seeking cost-effective and durable equipment for surface casing and vertical wellbore sections in onshore environments.
0SO stop collars are developed as counterparts to Centek’s Level 2 range of centralizers for less challenging wellbore sections.
0SO stop collars are available in sizes from 3 1/2" to 16".
