Strainer definition?

A strainer is a mechanical device which provides a means of removing solids from a flowing fluid or gas.

Strainers typically use perforated and/or wire mesh media for straining purposes. These materials are “two dimensional”, meaning they do not have a “depth” or “material holding” capacity. This means that when a material particle is caught in the straining media the opening is blocked or plugged. This results in an immediate reduction of available open area for flow. With this in mind, strainer sizing and selection are critical to ensure good cleaning cycle times, desired particle size retention, desired pressure drop, and acceptable velocity requirements are achieved.

General FAQ

Estimating pressure drop across strainers?

Weamco has pressure drop charts and graphs available for a variety of our strainers. (Please see specific strainer on web site or feel free to contact us at your convenience.)
The information on our charts and graphs is a combination of substantial engineering and a vast amount of actual experience.

In regards to estimating pressure drop across a clogged strainer, Weamco is very cautious and we typically resist engaging in this practice due to our many years of experience. Although there has been an attempt by many to estimate this scenario i.e., pressure drop of a clogged basket, we know from actual test results that the actual area clogged can have a significant influence to the flow and resulting pressure drop results. With this in mind since there is no way to know the pattern of the clogging of a basket at any given time, it is very difficult to accurately estimate the affect to pressure drop.

Calculating basket open area ratios (OAR)?

A common term used in strainer design is “Open Area Ratio (OAR)”. This equals the total open basket area divided by the internal cross-sectional area of the inlet pipe.

Published open area ratios for Weamco products are typically figured using a single 40% open area basket media. Open area ratios for Weamco fabricated permanent strainer types are calculated using the line of site method. There are two methods of instruction typically recommended by recognized establishments and manufacturers for calculating the open area of a strainer basket. One method referred to by the US military as “line of sight” uses the accrual of the open areas of the basket medias in series. Using this method, a 40% open area media in series with a 50% open area media has a calculated combined open area of 20%. An alternative method used in accordance with the US Underwriters Laboratories Standards, allows for the use of only the open area of the more restrictive media in the series. This would be 40% for the example above. In either case, the method used should be documented, as it has a direct impact on strainer design parameters such as sizing and estimating pressure drops.

What types of meter provers does Weamco manufacture?

• Bi-Directional pipe provers both stationary and mobile:
A positive displacement type prover with flow and displacer (usually a sphere) traveling in both directions by means of a 4-way diverter valve.
• Uni-Directional pipe provers both stationary and mobile:
A positive displacement type prover with flow and displacer (usually a sphere) traveling always in one direction, by means of a transfer chamber, or interchange.
• Volumetric Tank Prover:
As the name implies, this prover is a calibrated tank or vessel with a sight gauge and scale to read a metered volume. The flow must be stopped to determine the
volume.

Who is API?

The American Petroleum Institute (API) represents all segments of America’s oil and natural gas industry. Its nearly 600 members produce, process and distribute most of the nation’s energy. The industry supports millions of U.S. jobs and is backed by a growing grassroots movement of millions of Americans. API was formed in 1919 as a standards-setting organization. In their first 100 years, API developed more than 700 standards to enhance operational and environmental safety, efficiency and sustainability.
