How does a duplex strainer work?

While one filter chamber of the duplex strainer is in filtering mode, the other chamber is always with a cleaned filter element off line. The liquid passes through the filter element and over time the pressure drop in this filter chamber will increase.

What is the advantage of a duplex filter?

An inline duplex strainer will remove more particles or contaminants than a simplex filter, which is a more basic form of protection for pumps and valves. With a duplex strainer solution, your plant can process more product — and gain better control of particulates.

What is the use of duplex filters on board ship?

Filters are mounted in pairs as a duplex system so that one can be used and other is kept on standby at a time. The filter can be utilized both in low pressure (suction) and discharge (high pressure) side of the system and is used to remove the smallest part of dirt which is carried away in the system.

What is the properties of strainer?

Strainers remove solids from a fluid line. Some strainers may be available for specific types of media only. Strainers can be used to filter solids and particles from liquid flow streams. Strainers can be used to filter solids and particles from gaseous flow streams.

What is Y type strainer?

Y-Strainers are devices for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. They are used in pipelines to protect pumps, meters, control valves, steam traps, regulators and other process equipment.

What is the difference between a simplex and a duplex burner?

Simplex strainers require that the full basket be replaced with an empty basket and only after this process is complete can the flow be resumed. Duplex strainers are designed for the use of fluid handling where the flow cannot be shut down for basket cleaning or when the system becomes clogged.

What is difference between filter and strainer?

The key difference between strainers and filters are the size of the particles they remove. Strainers typically remove larger particles that are visible in a liquid or gas, while filters remove contaminants that are often so small, they cannot be seen with the naked eye.

What is importance of strainer?

Strainers are important components of piping systems to protect equipment from potential damage due to dirt and other particles that may be carried by the process fluid.

What is the use of strainer in piping?

Introduction to Strainer in Piping. Strainer can be defined as a pipe fitting through which liquid is passed for purification, filtering or separation from solid matter; anything used to strain a liquid; any device functioning as a sieve or filter used to prevent solid bodies from mixing in a liquid stream or flowline.

Are there specialist strainers used in oil and gas industry?

It is not intended to be a definitive work and does not cover specialist strainers. Instead it is focused on the most common strainers used in today’s process applications in the oil and gas industry.

When to seek expert advice on a strainer?

It is always recommended to seek expert advice from the respective filter and strainer specialist for each application. The following information is fundamental to ensure the correct specification of strainer equipment for its intended purpose. The common purpose of a strainer is to remove debris from a process stream.

What are the effects of an undersized strainer?

An undersized strainer will result in increased maintenance required to continually clean the elements. In the worse instances it can create pressure drop problems in a process stream.

Why is a maximum pressure drop important for a strainer?

It is therefore important that the maximum allowable pressure drop for the strainer is determined to ensure that the design of the strainer will not present problems to downstream process equipment. As with all piping equipment it is important to specify the design pressure and temperature range.
