What Types of Filtration, Separation, and Straining Equipment Does Winston/Royal Guard Offer?

Winston/Royal Guard Corporation designs and manufactures separation, filtration, coalescing, and straining equipment for oil and gas, natural gas gathering and transmission, refining, petrochemical, power, pulp and paper, and other process industries. According to the company's website, its product line covers filtration units and cartridges for gas and liquid, coalescers, natural gas filter-separators, separators and scrubbers for gas, steam, and air, a full range of strainers, sample coolers, and line blinds and bleed rings. If your process involves removing solids, liquids, or aerosols from a gas or liquid stream, the catalog likely includes a matching equipment category; the sections below map each category to its typical duty so you can judge coverage against your own process needs.

Filtration and Coalescing

The filtration side of the catalog is organized around removing particulate and liquid contaminants from both gas and liquid streams.

• Filtration units (gas and liquid): packaged filter vessels, such as the Type 61V unit shown with high-flow filter cartridges, that house cartridges for particulate removal.
• Filter and coalescing cartridges: replacement elements for the filter vessels, covering both straight filtration and coalescing duty.
• Coalescers (gas and liquid): equipment that merges fine liquid droplets into larger ones so they can be separated from the gas or liquid phase.
• Filter-separators for natural gas: combined units that remove solids and entrained liquids from natural gas in one vessel.

These categories are relevant when your goal is protecting downstream equipment, meeting gas or product quality specifications, or recovering entrained liquids.

Separators and Scrubbers

For bulk liquid removal rather than fine filtration, the site lists:

• Separators for gas, steam, and air: vessels that remove entrained liquid from a gas stream by gravity and mechanical means.
• Scrubbers for natural gas, steam, and air: equipment that washes or knocks out contaminants from these gas streams.

Separators and scrubbers are typically the first stage ahead of finer filtration or coalescing, so the catalog supports building a multi-stage treatment train from a single supplier.

Strainers

Strainers are listed as a distinct product family with several configurations:

The choice among these depends on whether your line can be shut down for basket cleaning, how much space the installation allows, and whether the strainer is permanent or temporary.

Sample Coolers, Line Blinds, and Bleed Rings

Beyond the core separation and filtration line, the site lists two supporting categories:

• Sample coolers for hot liquids, gases, and steam: used to bring a sample down to a safe handling temperature before analysis.
• Line blinds and bleed rings: isolation and verification hardware for piping systems, useful during maintenance and turnaround work.

Manufacturing and Quality Context

The company states it has provided these solutions since 1958 and manufactures in White Oak, Texas, in a facility certified to ASME Section VIII, Division 1, with National Board certification. It also states capabilities for all types of non-destructive testing under a controlled quality control system. These certifications matter if your specification or jurisdiction requires code-stamped pressure vessels.

How to Decide Whether the Catalog Covers Your Need

Use the following checklist against your process:

1. Identify the contaminant: solids only (strainers or filter cartridges), free liquid (separators or scrubbers), fine aerosols (coalescers), or a combination (filter-separators).
2. Identify the fluid: gas, liquid, steam, or air — the catalog is organized along this line, and some product families are specific to natural gas.
3. Decide on continuous vs. batch duty: this determines simplex versus duplex strainers and whether spare capacity is needed.
4. Check code and testing requirements: confirm that ASME Section VIII, Division 1 and National Board certification, plus the stated non-destructive testing capability, satisfy your project specification.
5. Confirm the ancillary scope: if you also need sample conditioning or positive isolation, the sample cooler and line blind/bleed ring categories may complete the package.

If your application falls outside these categories — for example, specialized membrane or thermal separation — the site's product list does not indicate coverage, and you would need to confirm directly with the manufacturer.
