Description

Horizontal Quick Opening Closure is an integral, scalable locking ring structure, Compared with other type of quick opening closure, it shorten the time of opening and closing, and only a person with less than 200N force can easily finish in one minute. With unique self-tightening type lip seal structure, makes the sealing more reliable.

1. Introduction

The Horizontal Quick Opening Closure (QOC), an essential component in pipeline operations, has been ingeniously engineered to streamline access to pressure vessels in horizontal installations. This indispensable device is a testament to the industry’s commitment to safety, efficiency, and technological innovation.

2. The Function of the Horizontal QOC

In the intricate world of pipeline operations, the Horizontal QOC plays a crucial role. Its fundamental function lies in offering an optimal balance between secure containment and quick accessibility to pressure vessels. This is achieved by a unique design that allows the pressure vessel to be safely sealed under high pressure and rapidly opened when necessary.

The importance of the Horizontal QOC becomes particularly evident during maintenance, inspection, and emergency operations. In such situations, timely access to the interior of the pressure vessel is paramount. The Horizontal QOC facilitates this swift access, thereby minimizing downtime and ensuring that operations can resume expeditiously.

The relevance of the Horizontal QOC is also underscored in the context of pigging operations. Here, it serves as a secure gateway for the entry and exit of ‘pigs’ – devices deployed for cleaning or inspecting the pipeline. The Horizontal QOC ensures a seamless execution of these operations, contributing to the overall efficiency of the pipeline system.

3. Design and Compliance

The Horizontal QOC boasts a robust design enabling it to withstand the pressures often experienced in pipeline systems. Despite this sturdy construction, the device’s design allows for quick and easy opening and closure, a feature that markedly enhances operational efficiency.

In terms of compliance, the Horizontal QOC meets the stringent requirements of industry standards such as ASME and UG 35. This adherence to recognized benchmarks ensures that the device meets safety and performance expectations. Moreover, the Horizontal QOC is versatile enough to accommodate client-specific customizations, further underlining its adaptability to diverse operational requirements.

4. Models and Connection Types

The Horizontal QOC is available in two distinct models: the NLS (segment type) and the WOCC (yoke type). These different models cater to various requirements and applications, enhancing the device’s utility across various pipeline configurations.

In addition to the model diversity, the Horizontal QOC also offers a selection of connection types, including Butt Weld (BW) and flanged connections. This flexibility allows the device to seamlessly integrate into different pipeline setups, ensuring that it meets the unique needs of each application.

5. Material Construction

The construction of the Horizontal QOC utilizes high-grade materials such as ASTM A350, ASTM A105, and ASTM A694. This choice of premium materials ensures that the device can resist the harsh conditions often encountered in pipeline operations, thereby guaranteeing durability and long service life.

Moreover, the Horizontal QOC features corrosion-resistant cladding, such as Grade 316 SS/ Inconel 625. This protective layer significantly enhances the device’s resistance to corrosion, further boosting its durability and performance in the long run.

6. Conclusion

In conclusion, the Horizontal Quick Opening Closure has emerged as an indispensable tool in the landscape of pipeline operations. Its ability to offer quick access to pressure vessels, its robust design, and its compliance with industry standards all contribute to its vital role in the industry.

Furthermore, the versatility of models and connection types, coupled with the high-grade materials used in its construction, emphasizes the device’s commitment to durability, adaptability, and performance.

The Horizontal QOC is not just a device but a symbol of operational efficiency, safety, and technological advancement in the pipeline industry. Its presence continues to shape the industry, demonstrating the power of engineering solutions in addressing operational challenges and enhancing overall pipeline performance.
