Pressure Control Equipment Repair, Refurb and Certification
In the oil and gas sector, precision-engineered components are critical to maintaining safety and operational efficiency—especially when it comes to pressure control and flow regulation. This includes Ram and Annular Blowout Preventers (BOPs), Wireline and Coiled Tubing BOPs, and robust Drill-through Equipment, all essential for high-pressure well intervention. Wellhead and Christmas Tree systems provide the backbone of surface pressure control, while a range of valves, chokes, and specialized assemblies ensures safe flow management. Our expertise extends to the manufacturing, repair, and maintenance of equipment certified to API 6AR and 16AR standards, delivering reliability in the harshest environments and meeting the strictest compliance requirements across global operations.
Following several well-control incidents in the drilling industry, API introduced the API 6A and API 16AR standards to govern the service and repair of wellhead and drill-through equipment. Pioneer Engineering strictly adheres to these requirements, and our Certificates of Conformity demonstrate full compliance with these internationally recognized standards.
