Applications of Ball Valves in LNG and Natural Gas Systems

Unison Valves is a ball valve manufacturer in Maharashtra that has been delivering superior flow control solutions for the past four decades. Whether it's ball and butterfly valves, thermodynamic steam traps, or other industrial valves, Unison Valves has stayed true to the unwavering ethos of supplying high-quality products each time.

Methane-based natural gas is a clean energy source used in industrial, heating, and power generation. It transforms into Liquefied Natural Gas (LNG) around -162°C, allowing for effective transportation.

Here's why ball valves are used in natural gas pipelines. LNG operations require extreme precision and extensive precautions because of their explosive nature. Application of ball valves in LNG systems is engineered to work effectively in both low and high-pressure systems, making sure precise control over gas flow and reducing the danger of leakage, which is crucial in natural gas applications, to avoid risks, guarantee compliance, and ensure operational integrity.

Why Ball Valves Are Ideal for LNG and Natural Gas Systems

Ball valves are ideal for LNG and Natural Gas systems as they have a lot of benefits of ball valves in the natural gas industry, some of which are:

Leak-Proof Shut-Off for Hazardous Media

Even in conditions of high pressure and temperature, these valves provide dependable operation because of their durable structure and well-developed seals. They are perfect for essential shut-off points because of their rapid, quarter-turn action, which improves response during emergencies. 

These valves offer the security that comes with reliable, leak-proof control in settings where even a small leak can have major repercussions.

Low Torque and Quick Operation

Ball valves require less torque, which makes them easy to operate. The valve is capable of being fully opened or closed with barely any effort due to the quarter-turn mechanism. This function is especially useful for systems that need automatic actuation or frequent operation. The valve's dependability is further increased by the decreased torque, which also lessens wear on the stem and seals.

Key Applications in LNG and the Gas Industry

LNG Liquefaction and Storage Terminals

Ball valves are essential to regulate the flow of liquefied gas at LNG terminals during both liquefaction and storage. When working with hazardous gases at cryogenic temperatures, they guarantee safe isolation and tight shut-off. Ball valves like cryogenic ball valves in LNG systems keep things safe and efficient, whether they're isolating parts for maintenance or regulating flow into storage tanks.

Natural Gas Pipeline Systems

Ball valves are essential for long-distance natural gas pipelines. They allow operators to quickly shut off and redirect the flow of the liquid, especially during emergencies and timely inspections. Their durability in high-pressure environments helps to ensure safe and uninterrupted transmissions.

Onshore/Offshore Exploration Facilities

In both onshore and offshore exploration facilities, ball valves are used in a high-

pressure environment to ensure leak-proof flow of liquid gases like LNG. These ball valves can withstand harsh weather, saltwater exposure, and extreme weather conditions, making ball valves a reliable solution for flow control.

Processing and Compression Plants

Ball valves for gas distribution and metering are essential for controlling the flow of gas through different compression and processing phases. In systems that are subjected to high levels of stress, they offer accurate control and quick shutdown. Their leak-proof construction guarantees the safe handling of hazardous media, preserving plant productivity while safeguarding the environment and employees.

Types of Ball Valves Used in Gas Applications

There are a few types of ball valve gas flow control, each is suited for specific applications.

Floating Ball Valves

In low-pressure settings, floating ball valves provide a durable seal. These multipurpose valves ensure a tight seal by pressing the ball against the seats using the fluid's pressure. They’re commonly employed in smaller pipelines.

Trunnion-Mounted Ball Valves

These valves, which are made for high-pressure applications, have a supported ball design that keeps the ball from moving under pressure. In large-diameter pipes, where stability is crucial, they are extremely helpful.

Fire-Safe and Blowout-Proof Designs

In the oil and gas industry, safety is a non-negotiable; that's why ball valves are fire-safe and have blowout-proof designs. Ball valves used in LNG and natural gas systems are therefore constructed with blowout-proof and fire-safe designs.

In order to guarantee that they can continue to provide a dependable seal even in the case of a fire, these valves are tested to satisfy international safety requirements such as API 607 and ISO 10497. Another line of defense is provided by blowout-proof stems, which keep valves from failing under extreme pressure. These design elements make them a reliable option in crucial applications by protecting people, property, and the environment.

Compliance and Safety Considerations

API 6D, ASME B16.34, ISO 17292

The specifications for metal ball valves ideal for petrochemical, natural gas, petroleum, and other related industrial applications are outlined in ISO 17292. Coming to the API 6D certified ball valves for gas, they outline the provisions for pipeline valves with lengthier pressure periods, more test items, and difficult operating procedures. ASME B16.34 requires general testing guidelines for hydrostatic shell and seat tests and fire testing is optional and not specifically addressed in the standard.

Fire Testing, Fugitive Emission Tests

In order to satisfy ISO/ASME standards for LNG valves, the systems undergo extensive testing. These guidelines guarantee that valves can survive harsh circumstances, such as exposure to fire and high pressure. While emission tests concentrate on reducing fugitive gas leaks, fire testing verifies that the valve maintains a tight seal both during and after a fire. For crucial oil and gas applications, these certifications collectively ensure that the valves are dependable, emission-tight, and fire-safe.

Anti-Static and Blowout-Proof Features

A ball valve's antistatic feature is a safety feature that stops the static charge created when the metallic and polytetrafluoroethylene (PTFE) seats come into contact. Failure to control the static charge generated in the valve may result in flammable media burning.

The purpose of the anti-blowout stem feature is to prevent the stem from being forced out of the valve body by the inline pressure. By including an inverted T-shaped shoulder design for the stem, which is then inserted from inside the valve body, the anti-blowout stem feature is accomplished.
