Safety valves for Oil & Gas
Safety and Reliability for the Oil & Gas Industry
Safety valves designed to ensure maximum control and regulatory compliance.
Industry Requirements
Periodic Safety Valve Inspections
In the Oil & Gas industry, one of the main challenges is ensuring the reliability and compliance of pressure equipment, particularly safety valves (PSV), throughout the lifecycle of the plant. End users typically perform preliminary checks before commissioning and subsequent periodic tests, as required by local regulations, which generally mandate an annual PSV inspection.
These inspections are crucial to ensure that the valves function correctly in the event of overpressure and continue to protect the system after the checks. For this reason, it is essential that the valves are designed with materials and technical solutions that preserve their integrity and functionality even after repeated tests, preventing malfunctions or leaks that could compromise safety and operational efficiency.
Operational Continuity in Oil & Gas Plants
In the Oil & Gas industry, operational continuity is critical, as any downtime, even partial, can result in enormous economic losses. Extraction, refining, and transport plants operate with high production margins, moving billions of dollars each year. A failure of a safety valve (PSV) or another critical component can lead to production disruptions, with costs potentially reaching millions of dollars per day. Additionally, sudden plant shutdowns can compromise safety, increasing the risk of accidents and penalties for non-compliance with regulations.
For this reason, choosing reliable and certified components is essential to ensure continuous operation, reduce maintenance downtime, and protect both the financial investment and the safety of the plant.
Where Are Safety Valves Located?
Nuova General Instruments safety valves are installed in Oil & Gas plants to protect the system from overpressure and ensure operational safety. These valves are typically located near pneumatic actuators that drive shut-off, control, or regulating valves. Their function is to automatically intervene in the event of excessive pressure, preventing damage to the actuator and piping.
They can be installed both on the actuator inlet side and on discharge lines to ensure safe operation of the entire system, particularly in plants with high pressures and critical operating conditions. The safety valve activates when the pressure exceeds the predefined limit, allowing the controlled release of fluid or gas to prevent failures and ensure the proper functioning of the system.
Challenges and Critical Issues in the Industry
Wear and Reliability of Safety Valves Over Time
The frequent opening and closing of safety valves, even for short periods, accelerates the wear of seals and contact surfaces, reducing their reliability over time. This can compromise the seal, increasing the need for maintenance and the risk of failures. If the PSV (Pressure Safety Valve) does not operate correctly in the event of overpressure, actuator damage may occur, and in extreme conditions, there is a risk of explosion.
What is Nuova General's Solution?
To ensure reliable operation over time, we use high-performance soft seals, designed to provide a hermetic closure even after each valve intervention. This minimizes the risk of leaks and ensures the safety of the system.
The particular design of our seals not only improves the valve's sealing ability but also offers greater resistance to particles and impurities present in the process fluid. This allows our valves to maintain consistent performance, reducing the need for maintenance and ensuring long-lasting protection for the systems.
Certified Materials for Extreme Environments and Corrosion Resistance
In Oil & Gas plants, safety valves operate in environments with harsh conditions, including high humidity, extreme temperatures, exposure to aggressive substances, and highly corrosive atmospheres. To ensure reliability and long-lasting performance, it is crucial that the materials used are certified and corrosion-resistant, minimizing the risk of degradation and malfunctions.
What is Nuova General's Solution?
Our valves are made with 100% Italian materials, ensuring complete traceability and maximum quality. All components are selected to withstand the harshest environments typical of the Oil & Gas industry, ensuring safety and reliability over time.
The use of special corrosion-resistant steels and 316L stainless steel guarantees optimal performance even in the presence of aggressive agents, saline humidity, or extreme temperatures. For pressure parts, a material certificate 3.1 is available upon request.
Limited Installation Space for Safety Valves in Oil & Gas Actuators
In Oil & Gas plants, pneumatic actuators on ball valves and other large valves often operate in confined spaces, where every component must be optimized to ensure efficiency without compromising safety. The installation of safety valves (PSVs) in these systems can be complex due to restricted layouts and plant configurations, requiring compact and reliable solutions.
What is Nuova General's Solution?
Nuova General safety valves for Oil & Gas actuators are designed to fit in tight spaces without sacrificing performance. Their compact design allows for easy integration onto pneumatic actuators, ensuring effective protection against overpressure. Thanks to their optimized structure, they facilitate installation and maintenance, reducing the footprint while ensuring reliable operation even in space-constrained environments.
Certifications and Standards for the Oil & Gas Industry
In the Oil & Gas industry, the geographical location of plants directly impacts the certifications required for safety valves and pneumatic actuators. Plants located in Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan must obligatorily comply with the EAC (EurAsian Conformity) certification, which ensures compliance with local technical standards and allows operation in these markets.
On the other hand, plants located in North America and global projects with U.S. standards, such as those in the Middle East, must adhere to ASME regulations, specifically ASME VIII/ASME XIII for pressure equipment and ASME B31.3 for process piping, to ensure the structural integrity and operational safety of equipment.
Proper certification of safety valves is therefore a crucial aspect of providing reliable components based on the geographical location of the plant.
