What is an or***ce plate?

Or***ce plates are one of the most widely used flow measurement devices in industrial pipelines. By creating a controlled restriction, they generate a differential pressure that can be converted into an accurate flow rate for liquids, gases, and steam.

In our latest guide, we cover:
- How differential pressure flow measurement works
- The role of the vena contracta, pressure taps, and transmitters
- Different types of or***ce plates and when to use them
- Accuracy, pressure loss, and turndown considerations
- How or***ce plates differ from strainers and why both are often needed

If you’re specifying flow measurement or troubleshooting accuracy, pressure loss, or fouling issues, this article walks through the fundamentals clearly and practically.

Different types of strainers in a pipeline – what to use and why

From Y strainers and basket strainers to duplex, tee, and temporary start-up screens, not all pipeline strainers do the same job. The right choice depends on pressure, temperature, solids load, maintenance access, and whether the line can afford downtime.

This guide covers:
- The main types of pipeline strainers and how each works
- Where Y, basket, duplex, tee, and temporary strainers are best used
- Sizing fundamentals like mesh, open area ratio, flow velocity, and pressure drop
- Practical maintenance tips to extend service life and avoid unplanned shutdowns

If you’re specifying, replacing, or maintaining a strainer and want to avoid unnecessary pressure loss or frequent cleaning, this article lays out the essentials clearly.

Why You Should Use a Customised Basket Strainer

Off-the-shelf strainers work for simple duties, but many industrial systems are anything but simple. Flow rates vary, solids profiles change, space is tight, and downtime is expensive. A customised basket strainer is designed around the real operating conditions, not catalogue averages.

In this article, we explain:
- When standard basket strainers fall short
- How custom mesh size and basket open area reduce pressure drop
- Material selection for corrosive, high-temperature, or hygienic services
- Design options for tight layouts, high solids loading, and continuous operation
- Where mist eliminators fit alongside strainers in gas and steam systems

If you’re dealing with frequent cleaning, rising differential pressure, or a strainer that never quite fits the system, this guide shows why a tailored approach delivers better reliability and lower lifetime cost.

Are Strainer Baskets Interchangeable?

It’s a common question during maintenance and replacements, but most strainer baskets are not universally interchangeable. Differences in housing geometry, seat design, sealing method, open area ratio, materials, and pressure class all affect whether a basket will fit and perform correctly.

In this article, we cover:
- Why baskets and housings should be treated as a matched system
- What actually needs to match before a swap is considered safe
- OEM vs quality aftermarket replacement baskets
- How basket design affects differential pressure and cleaning frequency
- A clear step-by-step process to select or replace a basket correctly

If you’re dealing with worn baskets, rising differential pressure, or an unknown brand, this guide explains how to avoid bypass, premature clogging, and downstream equipment damage.

Simplex vs Duplex Strainers - what’s the difference?

Choosing the right strainer comes down to one key question: can the system stop for cleaning, or does it need to run continuously?

In this article, we break down:
- How simplex and duplex strainers work
- When a brief shutdown is acceptable and when it isn’t
- The impact on uptime, maintenance, space, and cost
- Typical applications across water, HVAC, chemical processing, oil and gas, and power generation

If you’re specifying strainers for a new system or reviewing an existing installation, this guide helps clarify which option fits the job and why.

In industrial filtration systems, simplex and duplex are the two main types of industrial strainers used to meet different operational needs.

Basket strainer or Y strainer? The right choice depends on debris load, pressure, space, and how often the line can be taken offline.

This article breaks down:
- When a basket strainer makes sense for higher flows and heavier solids
- When a Y strainer is the better fit for compact or high-pressure services
- How screen area, pressure drop, and cleaning intervals differ
- Why duplex basket strainers are often used where downtime is not an option

If you are selecting strainers for water, steam, oils or process lines, this guide helps match the strainer type to the duty rather than relying on habit or guesswork.

The Difference Between Filters and Strainers

Filters and strainers are often treated as interchangeable, but they solve very different problems.

Using the wrong one can mean unnecessary pressure loss, higher maintenance, or equipment that is not properly protected.

In our latest article, we clearly explain:

- The real difference between filters and strainers
- When a strainer is enough, and when a filter is required
- Typical particle size ranges, mesh and micron crossover points
- How pressure drop, flow rate, and maintenance differ between the two
- Where each should be installed in an industrial system

If you are specifying new equipment, upgrading a line, or troubleshooting pressure issues, this guide helps you choose the right solution the first time.

Industrial Strainer Cleaning Procedures

Strainers do not fail suddenly. Most issues build up through rising pressure drop, restricted flow, and missed maintenance.

Our latest article sets out a clear, site-ready approach to industrial strainer cleaning, including:

- Safe isolation, venting, and depressurisation steps
- When ΔP indicates it is time to clean, not guess
- Correct cleaning methods for basket and Y strainers
- Common mistakes that damage screens and shorten service life
- How to set maintenance intervals based on real operating data

If strainers protect pumps, valves, meters, or heat exchangers in your system, this guide helps reduce unplanned shutdowns and extend equipment life.
