Why Do You Need Industrial Strainers?

Industrial strainers are essential for pipeline cleaning, process protection, and arresting debris. Learn about your process’s different types and sizing of strainers and filter systems. In addition to filter types and sizing, industrial strainers are also necessary for backwashing purposes. Read on to learn more. Listed below are a few reasons you might need these types of strainers.

The function of industrial strainers

The purpose of an industrial strainer is to remove impurities from flow systems. They come with inbuilt wire mesh of varying sizes. Typically, they are supported by a perforated sheet. Smaller holes in the mesh can cause the fluid to flow more slowly, resulting in undue pressure drop. On the other hand, larger holes allow for greater differential pressure and require less frequent washing. A few key factors to consider when selecting industrial strainers Ontario are:

Pot filters are another option for removing solid materials. The system can detect when the basket is full, directing the flow to other strainers in the system. Some filters come fastened with ball valves, which are quarter-turn valves. They are durable and dependable but do not offer the managerial features of other strainers. Moreover, some pot strainers have multiple compartments designed to protect the equipment. They are typically used in applications with abrasives and strong chemical reactions.

Types of industrial strainers

Gas and oil strainers have numerous applications in various industries. They are commonly used in upstream and downstream processes, including drilling oil, derrick/mast, draw works, top drives, mud/fuel tanks, and power/pump stations. In the downstream process, these strainers are typically used in filtration and hydrocracking. These strainers are commonly called TEE strainers. They are designed to replace the elbow in a piping run with a 90-degree configuration.

When selecting industrial strainers, the most crucial consideration is the type of pressure and temperature the product is likely to endure. For example, stainless-steel strainers typically have a one-gage-width perforation. In contrast, carbon steel and brass strainers have an overall thickness around the same as the diameter of the punched holes. However, the pressure limit that strainers can handle is an important consideration regardless of the material.

Sizes of industrial strainers

For most applications, the sizes of industrial strainers will depend on the size of the line, the pressure, and the type of dirt it must filter. While the size of the strainer may match the line size, it is crucial to consider the dirt volume it will handle and the maximum pressure drop allowed. Conversely, an undersized strainer can be problematic because of increased maintenance costs and pressure drops within the process stream. As such, choosing the right size is crucial to a successful project.

Basket strainers are available in various sizes, ranging from 0.5 square feet to over four square feet. They can be made of different materials and are compatible with both Style S and Style R strainer housings. These strainers are also available in custom designs. The main difference between basket strainers and wire mesh strainers is the material they are made of. Standard materials for basket strainers are carbon steel, stainless steel, Monel, and Hastelloy.

Backwashing capabilities

When selecting a suitable industrial strainer, it’s essential to consider the backwashing capabilities of the device. Automatic strainers must comply with ATEX Directive, Machinery Directive (522), and FEA-M. Multi-element designs have a separate backwash mechanism protected by a sheet of material. This prevents the backwash mechanism from damaging the media, resulting in less water waste and reduced maintenance costs. Backwashing capabilities are also essential considerations for pulp and paper industry operators focusing on reducing process downtime.

A backwashing strainer cannot retain large particles due to the narrow opening of its elements. In addition, the backwashing arm has to be very close to the screen to clean the element. This prevents large particles from passing through the element, and the biological film will form on the screen. This means that maintenance personnel must perform frequent backwashing procedures to remove the cake. In Kansas City, Missouri, a basket strainer was notorious for clogging and required extensive manual cleaning.

Cost of industrial strainers

Several factors determine the cost of industrial strainers. These factors include particle size, standard US mesh sizes, and service temperature. In addition, the life cycle cost, which accounts for capital and operating costs, also plays a role in determining the final selection. For example, basket cleaning and replacement are labor-intensive, and waste disposal costs can affect the final cost. Furthermore, downtime can increase production costs and ultimately impact the selection process. This article will review the factors that affect the cost of industrial strainers and provide you with an overview of the industry’s current price and future outlook.

Pipelines and industrial strainers must be able to remove impurities and debris during the process flow. Therefore, these industrial strainers are crucial for natural gas filtration. Most oil and gas strainers are made of corrosion-resistant materials such as copper and aluminum. Some types also feature an automatic blow-off valve to prevent sedimentation. Types of industrial strainers include simplex, y, and automatic strainers.
