Why Double Block And Bleed Valve Is Important for oil and gas project?

Different kinds of valves which can be used in the supply chain of oil and gas can be gotten from https://www.kplokusa.com, from the extraction in the field to the delivery to the final consumer; the priority is the safety of everyone in the sector. It is essential for the valves to have the ability to provide 100% tight seal regardless of whether it is reacting to emergency situation or you want to carry out maintenance or repair in some part of the pipeline.

Some double block and bleed valves are mainly installed to provide a safety measure and you may not need to close it. However, other ones may sit inactive on a pipeline for several years before it would be required, and it must also provide a 100% performance whenever it is needed in the industry.

For the pipelines which are used for transporting natural gas, crude oils and other derivatives of crude oil, it is compulsory to have a double block and bleed valve. This was incorporated by the report given in 1990 by Cullen when there was an occurrence of a disaster; it implies that you will need two separate valves so as to drain the space and release the pressure.

This is because, if the fluids have a passage via the first valve, the material will leave through the bleed which is opened rather than via the second isolate valve because such will move to the downstream section and later cause an accident. However, this would present a challenge, especially in the modern offshore project which involves floating production and storage facilities which has a lot of space and weight.

In the conventional system, you can achieve a block and bleed by the installation of two different ball valves independently, separate equipment which will allow the bleeding of the system should also be placed in between them.

But wherever it is crucial for you to have a space, this method would require more space when compared to a single valve which won’t make you achieve the desired result, especially when you have several valves which you need to upgrade along the line.

To solve the problem which most people are facing in the traditional system which would need more connection when compared to a single valve. The single unit style DBB valve which has three different valves in a single unit. This would help in increasing the safety of the system by removing the connections between separate units, thereby reducing the path where potential leaks can occur.

This will also help in reducing the volume of the cavity which is between the valves and also allow the operators to evacuate the space so that the isolation can be done quickly and in a safe manner. In addition to that the double block and bleed valve would help in averting danger in an emergency scenario.

This does not imply that the installation is limited to an existing structure without making changes on the pipes which are surrounding it, but it helps in the reduction of space by more than half thereby providing space for other equipment.

Also, because the valves have several bore, they provide a negligible pressure difference when it is open, thereby increasing the efficiency and allowing the engineers to carry out the inspection and maintenance.
