In industrial fields such as petroleum, natural gas, chemical engineering, and petrochemicals, the fire safety design of industrial valves is of vital importance. Once extreme situations like fires occur, whether the valves can maintain their sealing performance and normal operating functions under high-temperature environments is directly related to the safety of the entire industrial system.
Differences between API 6FA and 607
API 6FA and 607 are commonly used for fire safety tests. API 6FA is for valves of API 6A and 6D, while API 607 is applicable to quarter-turn valves and valves with soft seats. API 6FD is for check valves. For the fire safety test, the valve needs to withstand a temperature ranging from 750 °C to 1000 °C and a pressure equivalent to 75% of the maximum working pressure for 30 minutes. The leakage amount should be controlled, and after the test, the valve must be able to complete at least one opening and closing operation cycle. This is to simulate harsh working conditions to evaluate the fire safety performance.
Analysis of Fire Safety Terminology
Valves with "fire-safe by design" are designed based on the concept of fire safety but have not been verified through actual tests to confirm their performance. Valves with "fire-safe tested" have undergone fire safety tests but lack approval from third parties, and their performance needs further verification. Valves with "fire-safe approved and certified" have passed the tests, obtained approvals, and been certified according to multiple standards. Their fire safety performance is reliable, and users can use them with confidence.
Integrated Design of J-VALVES Ball Valves
The fire safety design of J-VALVES BALL VALVES fully considers the requirements of relevant API standards and is organically combined with surface treatment and coating processes. For surface treatment, special materials and techniques are used. The coatings on key components are resistant to high temperatures and corrosion, ensuring the integrity of the structure during a fire. Machining processes ensure the smoothness and precision of the surface, reducing the risk of leakage. For coating, appropriate fireproof coatings are selected according to different working conditions. Under normal conditions, they can effectively prevent corrosion and wear. In the event of a fire, they can quickly form a heat insulation layer to delay the transfer of heat and protect key components from the direct impact of high temperatures. The selected coatings have good adhesion and durability, ensuring fireproof performance throughout the service life.
Practice in Line with API Specifications
J-VALVES BALL VALVES strengthen the fire safety design on the basis of meeting the requirements of surface treatment and coating in relevant standards. Through their structures and processes, they perform excellently in the tests of API 6FA and 607, demonstrating the reliability of fire safety and meeting special requirements.
Summary
J-VALVES BALL VALVES have strict control over surface treatment and coating, attach great importance to fire safety design, meet the requirements of relevant API standards, and have excellent performance under both normal and extreme working conditions. They provide reliable valve solutions for industrial fields and safeguard the lives and property of users.
