Special Standards for C95800 Floating Ball Valves in Low-Temperature LNG Use

As is known to all, in the field of LNG (liquefied natural gas) low-temperature applications, the selection and design of valves are of crucial importance, because they need to stably maintain reliable sealing performance and ensure operational stability in the harsh low-temperature environment. The C95800 FLOATING BALL VALVE, as a commonly used low-temperature valve, must meet a series of special standards and numerous considerations during the LNG low-temperature application process. The following will elaborate on these standards in detail and finally present the differences between it and ball valves made of other common materials in the form of a comparison table.

I. Material Characteristics of the C95800 Floating Ball Valve

The C95800 belongs to the category of aluminum-bronze alloys. This alloy has excellent corrosion resistance and relatively high strength, and is especially suitable for low-temperature environment applications. Its main components include elements such as copper, aluminum, iron, and nickel. With this composition, even under extremely low-temperature conditions, it can still maintain good mechanical properties, and its impact resistance is also quite remarkable. As a result, the ball valves made of this material exhibit excellent performance in LNG application scenarios and can effectively resist the impact and corrosion caused by low-temperature media.

II. Special Standards in LNG Low-Temperature Applications

Low-Temperature Sealing Performance

In view of the low-temperature characteristics of the LNG medium, it is required that the valves must achieve zero leakage in the low-temperature environment. For the C95800 FLOATING BALL VALVE, it mainly relies on special sealing design and careful material selection to meet this requirement. Usually, its sealing surface will choose elastic materials or metal sealing materials with low-temperature resistance properties, so as to ensure that the sealing performance is not affected and remains stable in the low-temperature environment.

Low-Temperature Toughness of Materials

In the low-temperature environment, the toughness of materials is a key factor. The low-temperature toughness of the C95800 material is quite outstanding. It can ensure that the ball valve maintains the integrity of its structure under extremely low-temperature conditions and effectively avoid the brittle fracture phenomenon caused by temperature changes. Based on this, the ball valves made of this material show good performance in low-temperature applications and can calmly cope with the impact brought by extreme temperature changes.

Requirements for Non-Destructive Testing

To ensure the reliability of the valves during the low-temperature application process, strict non-destructive testing needs to be carried out on the C95800 FLOATING BALL VALVE. Specifically, it covers multiple detection methods such as radiographic testing, ultrasonic testing, and magnetic particle testing. Through the above testing processes, it aims to ensure that there are no defects inside the valve, thereby ensuring that it can operate safely and stably in the low-temperature environment.

IV. Manufacturing Standards for the C95800 Floating Ball Valve

API 6D: This is the design, manufacturing, and testing standard for pipeline valves in the petroleum and natural gas industry and plays an important regulatory role in the entire valve manufacturing field.
ASME B16.34: This standard focuses on regulating and defining the flange connection and pressure rating of valves.
ISO 5208: It mainly focuses on the testing and experiment of valves and clearly stipulates the corresponding standard requirements.

It is precisely relying on the above standards that clear and definite guiding principles are provided for the design, manufacturing, and testing of the C95800 floating ball valve, thereby ensuring that it can operate reliably and safely in the LNG low-temperature application scenarios.

V. Summary

To sum up, the C95800 FLOATING BALL VALVE shows significant advantages in LNG low-temperature applications. With its excellent low-temperature toughness and outstanding corrosion resistance, it can stably maintain the sealing performance and operational stability even in extremely low-temperature environments. Coupled with the regulatory constraints of strict non-destructive testing and manufacturing standards, this ball valve can fully meet the special requirements of LNG low-temperature applications. Compared with ball valves made of other materials, the C95800 floating ball valve exhibits excellent performance in the low-temperature application field and is undoubtedly an ideal valve choice for LNG low-temperature systems.
