From offshore developments to LNG, refining and mining upgrades worldwide, AMPO demonstrates integrated engineering capability, materials expertise and certified performance across severe service environments

AMPO POYAM VALVES (AMPO) continues to consolidate its position as a supplier of highly engineered valve systems across upstream, midstream and downstream energy and mining projects worldwide.

Recent deliveries spanning Saudi Arabia, Brazil, China, the US and Kazakhstan illustrate a portfolio defined by long design life, materials science expertise, severe service capability and integrated engineering support.

SUBSEA ENGINEERING BENCHMARKS IN KSA

In the Arabian Gulf, AMPO supplied several high-rating and large sized MRO valves for Aramco’s maintenance, refurbishment, and upgrade projects across its refineries and pipelines.

The order includes high-rating large-sized valves for sour service, such as 46-inch-600#, 40-inch, Class 600 and 30-inch, Class 600 ball valves, and a substantial package of 6-inch, Class900 gate valves, most of them with INC625 weld overlay.

These valves have been specifically designed to operate under the demanding conditions of Aramco’s facilities, ensuring safety, reliability, and compliance with Aramco’s SAMSS and IOGP standards.

AMPO also supplied critical subsea valves for two major offshore programmes led by Saudi Aramco.

For the CRPO 125 and 126 developments at the Abu Safah and Marjan fields, operated by Aramco with Lamprell as contractor, the scope covered two ABSF jackets and two production deck modules (PDMs) with associated subsea facilities.

The specification required valves capable of meeting API 6DSS while achieving a 50-year design life under aggressive offshore conditions.

AMPO delivered four 12-inch, Class 1500 subsea valves: Two hydraulically actuated top-entry ball valves, one manual top-entry ball valve and one manual subsea swing check valve, all with ring-type joint connections.

The ball valves were equipped with compact hydraulic actuators and configured in SPE/DPE arrangement.

Internally, the valves were clad with Alloy 625 weld overlay, enhancing resistance to corrosion and ensuring durability over extended subsea service.

A second subsea package was executed for the CRPO 82 and 83 projects at the Zuluf AH East and West oil fields, where new wellhead topsides, tie-in platforms and electrical distribution platforms were constructed.

For this project, AMPO supplied several 10-inch, Class 1500 gear-operated subsea swing check valves featuring a Class 4 ISO 13628-8 interface.

As with the earlier package, the valves incorporated Alloy 625 weld overlay to safeguard long-term performance in harsh marine environments while satisfying API 6DSS design criteria and 50-year life expectations.

SEVERE SERVICE & SMART INTEGRATION

Beyond the Arabian Gulf, AMPO’s offshore credentials were reinforced through deliveries to Brazil’s pre-salt sector.

For the P-84 (Atapu) and P-85 (Sepia) FPSO platforms operated by Petrobras, AMPO supplied eight 20-inch, Class 150 Duplex axial flow check valves.

Installed downstream of critical pumps, the valves protect against reverse pressure in the pipeline, a key requirement in floating production systems processing up to 225,000 barrels of oil per day and 10 million cu m of gas.

In Brazil’s mining sector, AMPO delivered an integrated severe service package to Samarco’s Germano Mine in Minas Gerais as part of the Momento 2 Filtragem Fase 2 renewal.

The project included 82 severe service ball valves up to 14 inches and two hydraulic power units (HPUs) engineered and manufactured in-house.

All valve flow paths and closure elements were coated with chromium carbide using HVOF technology to withstand abrasive service in tailings filtration.

The HPUs, developed by AMPO’s R&D team, formed part of its Integrated Smart Solutions approach, enabling automated and reliable valve actuation. Field service engineers supported installation, commissioning and operator training, aligning the valve package with Samarco’s objective of increasing dry stacking of tailings to 80 per cent.

Cryogenic performance has also featured prominently in AMPO’s recent portfolio. For the Caofeidian Xintian LNG Receiving Terminal in Hebei Province, China, the company supplied more than 200 cryogenic valves across three construction phases between 2022 and 2025.

The scope included a 32-inch, Class 1500 top-entry cryogenic ball valve installed in the regasification unit, alongside gate, globe and axial flow check valves up to 26-inch, Class 150 and 14-inch, Class 1500 ratings.

AMPO’s field engineering team provided on-site commissioning and start-up assistance, supporting safe integration into a facility designed to unload 12 million tonnes of LNG annually and equipped with twenty 200,000 cu m storage tanks.

In the US, AMPO completed a customised switch plug valve solution for a major Northeast refinery processing 144,000 barrels per day (bpd).

Installed in the Delayed Coker Unit, the 12-inch, Class 600 valve, manufactured in special alloy, performs high-temperature flow diversion between coke drums, a safety-critical function.

The package incorporated a fully engineered control panel with double redundancy, including a real-time plug position encoder and limit switches, ensuring seamless communication with the control room.

The entire assembly underwent final acceptance testing prior to shipment, followed by on-site installation and commissioning support.

After one year of operation, the system has maintained stable performance in continuous service.

In Kazakhstan, AMPO supplied 82 8-inch Hypercentric triple-offset ball valves for a metering station upgrade at Tengizchevroil.

The valves, equipped with electric actuators and Inconel overlay, comply with API 6D and passed PR2 testing.

A 6,000-cycle endurance test certified by DNV validated durability under extensive cycling.

Designed for high H2S content and erosive conditions, the friction-free seat arrangement limits wear by ensuring contact only at final closure, while the independent lower trunnion prevents particle accumulation.

Local support was delivered through AMPO’s hub in Atyrau, reinforcing lifecycle service capability in the Caspian region.

Across these projects, recurring themes include corrosion-resistant cladding, advanced coatings, compliance with API, ISO, ABS, TSG and DNV certification regimes, and in-house engineering of actuators and control systems.
