AMPO Service has completed the supply of a series of high-pressure, large-diameter maintenance, repair and operations (MRO) valves for Saudi Aramco’s refinery and pipeline upgrade initiatives. The delivery supports ongoing maintenance, refurbishment and modernization activities across several of the energy company’s operating facilities.
The project demonstrates AMPO’s capability to design and manufacture specialized valve solutions for complex operating environments, particularly in sour service conditions where materials and performance standards must meet strict industry requirements. The supply package includes several large-scale, high-rating valves engineered specifically for demanding industrial applications.
Among them are 46-inch Class 600, 40-inch Class 600, and 30-inch Class 600 ball valves, along with a large number of 6-inch Class 900 gate valves. Many of these units incorporate Inconel 625 weld overlay, a corrosion-resistant material commonly used in aggressive environments such as sour gas processing.
These valves are intended to operate in some of the most challenging service conditions within Aramco’s infrastructure. Their design ensures durability and operational stability while meeting strict technical specifications established by Aramco’s Saudi Aramco Materials System Specifications (SAMSS) as well as standards set by the International Association of Oil & Gas Producers (IOGP).
AMPO’s engineering teams worked closely with project stakeholders to ensure each valve met the specific performance and dimensional requirements necessary for integration into existing infrastructure. The company’s ability to produce high-rating valves internally, combined with specialized weld overlay capabilities, enabled efficient customization for this application.
A key factor in the successful execution of the project has been AMPO’s operational presence in Saudi Arabia. The local support structure allows the company to collaborate directly with Aramco’s engineering, procurement and supply chain teams throughout the project lifecycle. This proximity facilitates technical coordination, improves response times and supports timely delivery of equipment.
The valves were manufactured using advanced machining and fabrication technologies that allow for precise engineering and reliable quality control. AMPO POYAM VALVES’ production facilities are equipped to manufacture large and technically complex valves within tight project timelines, ensuring that critical maintenance schedules can be maintained.
In addition to producing new equipment, AMPO Service also specializes in supplying replacement valves that can be installed directly into existing systems. These “plug-and-play” solutions are designed to match the original face-to-face dimensions of installed valves, allowing operators to carry out replacements quickly while minimizing downtime.
Such compatibility is particularly important in maintenance projects where infrastructure modifications must be avoided and installation windows are limited. By designing valves that align with existing configurations, AMPO helps streamline upgrade and refurbishment programs for energy operators.
The successful completion of this order further strengthens AMPO POYAM VALVES’ footprint in the Middle East, a region that continues to invest heavily in energy infrastructure upgrades and operational efficiency improvements. Through projects like this, the company continues to support Aramco’s efforts to maintain and enhance its refinery and pipeline assets with engineered solutions that prioritize safety, reliability and long-term performance. AMPO’s ongoing collaboration with major energy operators highlights its role as a technology partner capable of delivering specialized valve solutions for the most demanding industrial services.
