Description

Production Feature

1. Short operating time: Locking-ring Quick Opening Closure as ite 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 easily finish in one minute;
2. With unique self-tightening type lip seal structure, make the sealing more safe and reliable;
3. With safety lock system has a self-locking function:
When the equipment is before booster, the fast-opening blind and the locking structure on the scheduled operating parts can all lock,if not reserve lock position, the equipment can not booster;
When the equipment is, before the blind flange cover is open, can completely make the container’s inner pressure relief, all realize the secondary pressure relief, to avoid the safety problems due to wrong operation.

I. Introduction

A Quick Closure is a mechanically sophisticated device specifically designed to function seamlessly with pressure pipelines and pressure vessels. This device is purposefully crafted to fit neatly onto the round openings of these systems, making it an integral part of the operation and maintenance of such infrastructure.

II. Components of a Quick Closure

A Quick Closure is not a simple, single-piece device. Rather, it is a complex assembly of multiple components, each contributing to its functionality and performance. It comprises a barrel flange, head cover, hook ring or clamp, and a sealing ring, which ensures a tight and secure fit when the device is in operation. A safety interlocking mechanism provides an added layer of security, while the opening and closing mechanism facilitates easy operation. A swing arm and a short section, when required, complete the structure of the Quick Closure.

III. Types of Quick Closures

There are several types of Quick Closures, each designed to meet specific needs and applications. These include the groove type, clamp type, buckle type, lock ring type, expansion ring type, and fixed pressure ring type. Despite their differences, all types primarily operate manually, giving the operator direct control over the opening and closing of the pressure vessel or pipeline.

IV. Design and Manufacturing Process

The design process of our Quick Closures follows the ASME VIII Div.1 standards, a well-regarded set of guidelines in the industry. To ensure structural integrity and performance, we employ the ANSYS finite element stress analysis. This computational method provides a detailed understanding of how the Quick Closure will perform under various conditions and pressures. The main pressure-bearing components of our Quick Closures are created from integral forgings, using low alloy high-strength carbon steel. This choice of material ensures durability and robustness, capable of withstanding high pressures and extreme conditions.

V. Corrosion Resistance and Compliance

In the manufacturing process, we apply a corrosion-resistant overlay welding technique. This process enhances the device’s ability to withstand various working conditions, extending its operational life and ensuring consistent performance. Furthermore, our Quick Closures can pass stringent hydrogen sulfide tests, demonstrating their resilience against corrosive gases. Compliance-wise, our Quick Closures meet and exceed the GB150 regulations and other relevant laws. Additionally, they adhere to the SY/T0556-2018 industry standard, a testament to their quality and reliability.

VI. Applications of Quick Closures

The applications of Quick Closures are extensive, spanning various industries and equipment types. They are essential in oil and natural gas gathering and transportation pipelines, where they provide a secure and easily accessible opening for maintenance and inspection. Pig launcher and receiver barrels also utilize Quick Closures, as do a variety of filters and filter separators. Furthermore, pressurized kettles and sulfurization tanks often employ Quick Closures due to their reliability and ease of operation. In fact, any equipment or system that employs a quick-opening door pressure vessel will likely utilize a Quick Closure.

VII. Technical Indicators of Quick Closures

Our Quick Closure’s technical indicators are a reflection of its high standards and quality. With a nominal diameter (Dn) of up to 1600mm and a design pressure (Pn) of up to 40 MPa, our Quick Closures can handle a wide range of applications. They are compatible with various working mediums, including oil, gas, and water. The design temperature range is from -50°C to 300°C, accommodating a broad spectrum of operational environments. The material of choice is carbon steel, known for its strength and durability. Lastly, the pipeline thickness can vary from 6mm to 100mm, depending on the specific requirements of the application.

VIII. Conclusion

The importance and efficiency of Quick Closures in the industry cannot be overstated. These devices provide a secure and easily accessible opening for pressure vessels and pipelines, making them essential for maintenance and operation. Furthermore, the adherence of our Quick Closures to industry standards and their robust design and construction make them a reliable choice for a wide range of applications. So with their versatility, reliability, and compliance with industry standards, Quick Closures continue to be a mainstay in the industry.
