Description

NRG GLOBAL MAKE Basket strainers are installed to protect equipment from damage caused by unwanted debris that may be in the pipeline. The unwanted debris could be dirt or other foreign particles that make their way into the process fluid. Typically, basket strainers are installed in horizontal pipelines and in situations where high flow capacity is required. These strainers are installed upstream of equipment like pumps, control valves, and traps, keeping potentially corrosive or damaging debris from making its way down the line. They can be installed alone or in a series to increase filtration. They may come with a single chamber (simplex strainers) or multiple chambers (multiplex strainers). To read more about the differences between simplex and duplex strainers, check out this post. Understanding Mesh Sizing Each strainer is designed with a mesh lined basket to filter and collect the unwanted debris. Mesh size should be chosen based on the job function, not the size of the system. Selecting a mesh with openings that are too small could result in more frequent clogged lines, while a mesh with significantly larger openings could permit more unwanted debris to flow through the pipeline and equipment. Ideally, then, you’ll want to choose a mesh where the perforation is slightly smaller than the smallest particle you’ll need to filter out. Mesh size is measured by the number of openings in one linear inch of screen. For instance, a 16-mesh screen would have 16 openings per inch, while a 100-mesh screen would have 100 openings. Higher numbers, therefore, are able to strain out smaller particles with a finer weave. The baskets are typically made of stainless steel for quality and durability. Factors for Selecting the Right Basket Strainer Each application could require a different basket strainer. Consider the unique functions of your pipeline before deciding on a strainer. Important factors include the pressure and temperature requirements of your line, the type of liquid flow (corrosive, abrasive, etc.), debris size, and the frequency of cleaning and maintenance. You may also consider a duplex style basket strainer (such as these), which holds two strainer baskets fed by diverting valves. This system allows one basket to be cleaned and serviced while the other maintains flow.
