The Centek OBH centralizer combines high performance with easy field assembly, making it ideal for onshore wells, including vertical and slightly deviated applications. Its innovative design allows it to be nested on a pallet, reducing delivery and storage costs by up to 30% compared to non-hinged centralizers. The OBH is engineered for durability and efficiency in the field, delivering consistent performance while simplifying logistics for operators.

Constructed from high-quality alloy steel, the OBH’s bow springs are hot bent to shape using precision dies and undergo a controlled heat treatment process to ensure uniform spring characteristics. Designed to exceed API 10D standards, the OBH offers an extended profile and is also compatible with a hinged stop collar, providing a versatile solution for wells with build rates under 10° per 100 feet and depths under 10,000 feet. Its ease of assembly and robust construction make it a dependable choice for applications where slip-on centralizers cannot be used.
