Product Description
Sphere Part
Crafted from premium, high-strength, corrosion-resistant metals like stainless steel 304 or 316L, the sphere part of the Xuqi 4-Inch Aluminium Alloy Coupling is engineered to perfection. Its meticulously processed surface ensures unrivaled smoothness, minimizing medium flow resistance and guarding against wear and tear during repetitive loading and unloading tasks. The innovative spherical design grants the coupling exceptional flexibility, allowing it to seamlessly adapt to varying angles and positions during connection and disconnection, thus elevating operational ease and efficiency to new heights.
Sealing Components
Equipped with high-performance sealing materials such as fluoroelastomer and nitrile rubber, this coupling demonstrates outstanding resistance to oil, aging, and chemical corrosion. These materials sustain a reliable sealing effect over extended periods, even in the most challenging environments. The ingeniously designed sealing structure, coupled with the precise interaction between the sphere and sealing parts, creates a dual-sealing assurance, effectively averting oil and gas leakage. This ensures both the safety and environmental responsibility of the oil and gas recovery process, offering peace of mind during operations.
Connecting Parts
Designed for versatility, the coupling's ends feature a standardized configuration, enabling quick and secure connections to an array of common pipelines, loading arms, and other equipment. Connection options include threaded, flange, and clamp adapters, allowing users to adapt based on specific needs and on-site conditions. Precision in the dimensions of these connecting parts guarantees impeccable sealing and stability, preventing any potential loosening or leakage during the critical loading and unloading processes, thereby optimizing operational integrity.
Working Principle
In the dynamic process of oil product loading and unloading, the spherical oil and gas recovery loading and unloading couplings work harmoniously with related equipment to achieve optimal results. When fueling, the coupling channels oil and gas from the tanker back to the storage tank or recovery device, thanks to its ingenious internal structure that promotes smooth flow. Simultaneously, the sealing components ensure airtightness, preventing atmospheric leaks. During unloading, the process reverses, maintaining a closed circulation system for oil and gas. This method not only minimizes environmental pollution but also significantly reduces the risk of fire, explosion, or other safety hazards caused by oil and gas accumulation, promoting a safer and more sustainable operation.
