Tianjin Polycarbonate Complex (Tianjin, China)


The 50-50 joint venture Sinopec Sabic Tianjin Petrochemical Co. Ltd (SSTPC) requested in 2019 the design and manufacture of several critical ball valves, some of them with the AMPO RCM valve condition monitoring system, with the aim to monitor the valves operation parameters which are really critical on the polycarbonate process.

Tianjin polycarbonate plant was developed by SABIC’s world-class advanced polycarbonate license, which was previously and successfully implemented on Sabic Cartagena plant in Spain. This complex has a production capacity of 260,000 polycarbonate tonnes per year.


AMPO POYAM VALVES produced and successfully delivered for this project diverse highly engineered isolation ball valves with double acting actuators and equipped by the AMPO RCM valve condition monitoring system, which is a predictive maintenance system patented by AMPO. The valves were installed on the most critical production lines of the polycarbonate complex. 

This AMPO RCM (Remote Condition Monitoring) system developed by AMPO POYAM VALVES monitors valves’ torque/position and detects possible future failures that may occur in the valves installed at the plant, so that they can prevent unexpected plant shutdowns and increase efficiency. Moreover, the system ensures that the valves are continuously connected, so that AMPO supplies monitoring and analysis of the situation of the valves.

Pennsylvania Chemicals project (Potter Township, Pennsylvania, US)


The petrochemical complex (now Shell Polymers Monaca) is a world-scale facility that produces 1.6 million tonnes of polyethylene pellets per year to create everyday products from food packaging to industrial and utility products. It comprises an ethane cracker, three polyethylene units, a 275MW combined cycle cogeneration power plant, a water treatment facility, and large product storage with rail and truck loading capabilities. 

Customers required during the construction of this megaproject the design, manufacturing and delivery of approximately 4,500 highly engineered valves while Bechtel was the Main Works Contractor for the construction, commissioning and startup of the facility. 


AMPO POYAM VALVES produced and successfully delivered for this project approximately 4,500 highly engineered and special valves such as cryogenic ball valves and high temperature (550ºC) ball valves for high pressure ethylene units. Due to the commitment of AMPO POYAM VALVES in this project and other key projects with Bechtel during this period,  AMPO POYAM VALVES was recognized in 2019 by Becthel as Top Supplier at the company’s annual Supply Chain Awards.

Companies were evaluated on multiple factors including: overall performance, ability to deliver quality services/supplies on time, ability to work collaboratively to meet milestones, and meeting or exceeding project expectations in aspects of safety, performance, technical expertise, and environmental compliance. Nominations were reviewed and approved by Bechtel procurement and project managers with final approval from senior leadership.

AMPO POYAM VALVES has been working hand in hand with Bechtel for more than 20 years, providing highly engineered valves for outstanding projects worldwide, such as: Pennsylvania Chemicals Project, Corpus Christi Liquefaction Project, Sabine Pass Licuefaction Project, Atlantic LNG, Australian LNG projects, Angola LNG, Jamnagar Refinery, Al Taweelah Alumina Refinery, etc.

SASA – PTA Production complex (Adana, Turkey)


SASA POLYESTER, one of the world’s leading manufacturers of polyester, fiber, filament yarn, polyester-based polymers, specialty polymers and intermediates, awarded to Técnicas Reunidas the execution of a project for a new petrochemical plant for production of PTA (Purified Terephtalic Acid) in Adana, Turkey, in 2020. The capacity of the plant will be 1.5 million tonnes per year.

Customer required during the construction of this PTA production complex, the design, manufacturing and delivery of approximately 7,100 highly engineered and special material valves. 


AMPO POYAM VALVES produced and successfully delivered for this project approximately 7,100 stainless steel, duplex, superduplex and titanium ball, gate, globe and check valves up to 32” and 1500 lbs. A special mention deserves the development of around 420 titanium valves up to 14” and 600 lbs for this project. 

AMPO has an extensive experience in projects involving PTA, ethylene, propylene, butadiene, benzene, toluene, xylene, methanol, fertilizers, U&O, helium, air separation plants, etc., where we offer highly engineered fluid handling solutions for the most demanding applications and in the most special materials.

Umid and Babek fields further development project (Azerbaijan, Caspian sea)


Customers required the design, manufacturing, and delivery of several Subsea isolation ball valves (SSIV) and Subsea NRV swing check valves for the Umid and Babek fields further development project. Located at 75Km far from Baku in the deep-water of the Azerbaijani sector of the Caspian Sea, The Umid-Babek fields have estimated reserves of 600 billion cubic meters gas and 110 million tons of condensate at minimum.


AMPO POYAM VALVES produced and delivered for this project 20” 1500 lbs API6DSS Subsea isolation ball valves, which have been destinated to create a safety barrier to protect the Umid-2 offshore platform from unexpected contingences. Additionally, 20” 1500 lbs API6DSS Subsea swing check valves were also delivered for the same project. The whole scope of valves undergone extensive R&D to guarantee reliability and safety, as well as qualification testing according to the API 6A PR2. The PR2 test qualification was performed at AMPO POYAM VALVES’ Product Performance Test Lab, integrated in the valve manufacturing facilities in Idiazabal and carefully overseen by Bureau Veritas to ensure and validate the integrity of the valves design and its components. Regarding valve manufacturing, a special mention must be made to the stem, which was manufactured in INCONEL alloy 725, a highly resistant material to corrosion not in mention to the AMPO In-House overlay process with Inconel 625 performed in our New Machining Center covering all the internal parts of the valves in contact with the fluid. Finally, a true metal to metal stem sealing solution was also applied to guarantee an operational extended life for both type of valves.
