Product Introduction

Stainless steel honeycomb inner floating roof with full liquid connection (product introduction)

In the field of petrochemical storage technology, in order to prevent the medium from escaping and causing environmental pollution and safety hazards, and to reduce volatilization losses, the country is currently using a large number of floating tubes as the buoyancy unit of the floating tubular inner floating top. Although it can greatly reduce the oil and gas loss, there is an oil and gas space between the floating disk and the liquid surface, and the medium has volatile conditions and overflows through the floating roof cover. Sealing performance is not ideal, there are safety risks. According to the State Administration of Safety Supervision “on further strengthening the safety management of chemical tanks notice” Safety Supervision General Management three [2014] No. 68: Article (b): strengthen the management of production and operation of chemical tanks, normal operation is strictly prohibited in the floating roof tanks floating plate and the formation of space between the material. 68 for the internal floating roof structure puts forward clear requirements, in order to solve the problem of the internal floating roof structure, the internal floating top cover plate and the liquid surface of the oil and gas space. In order to solve the problem of domestic internal floating roof tanks floating roof technology is backward, there is no oil and gas space of the internal floating roof. Combined with the technical status quo of floating roof without oil and gas space in foreign countries, we have developed a self-intellectual property rights with honeycomb box buoyancy unit of liquid-immersed internal floating roof.

It has the following features:

1. Fully liquid-connected stainless steel honeycomb inner floating roof is completely immersed in liquid, module fully immersed and sealed fully immersed, no oil and gas space, preventing oil and gas volatilization.

2. The buoyancy element adopts all-welded design, and the buoyancy of the fully liquid-connected stainless steel inner floating top is designed to be more than 2.5 times of the weight of the floating disk.

3. The whole liquid-connected stainless steel inner floating top adopts honeycomb core buoyancy unit module, with high overall structural strength, good stability and long service life.

4. Good sealing is required between the outer edge of the inner floating roof and the tank wall, and a new generation of high-efficiency elastic seal with large compensation can be adopted, which solves the problem of traditional sealing leakage failure.

5. Convenient and quick construction, easy to assemble. All parts are accessed through the manhole, no need to open the roof and fire work.

Technical description:

1. Solid structure, strength exceeds API650 (H4.2.1.4) requirements by more than 7 times.

2. The buoyancy is more than 2.5 times of its own gravity and is relatively independent, which makes the buoyancy unit of the whole floating roof evenly divided into millions of parts and completely avoids the chuck accident caused by the loss of buoyancy.

3. The honeycomb float box is the buoyant element of the fully connected liquid floating plate. The overall technology draws on the application of honeycomb panels in aerospace, trains, and ships, i.e., the honeycomb panels are characterized by high structural strength, light weight, and high flatness under the same volume, which meets the requirements of the buoyant element.
