1. Confirm the application fit

The product description lists these uses for fiberglass scrubbers:

• Liquid storage and water treatment
• FGD (flue gas desulfurization) systems
• Chemical processing and pollution control
• Gas cleaning and control of gaseous emissions, especially polluted gases
• Waste incineration and power generation processes

If your project involves an FGD scrubber for a power or incineration line, an FRP design is a reasonable option to discuss. Ask for a project-specific review before you go further.

2. Understand why FRP is being considered

The product description compares FRP with metal and rubber-lined steel. It says FRP is lightweight, strong, can be produced in a wide range of diameters, and resists abrasion, chemical corrosion and rust, as well as very low and very high temperatures. It also says the smooth interior gives good flow characteristics and is easy to clean.

These are general material claims, not guarantees for your process. Chemical and temperature resistance depend on the specific medium and operating conditions. Treat them as reasons to evaluate FRP, then confirm them against your own process data.

3. Prepare the specification data the design depends on

The description says each new project is analyzed, and the system performance specifications are reviewed to select materials and construction methods. The design is then based on these requirements:

If any of these inputs are missing from your RFQ, expect the supplier to ask for them before quoting a design.

4. Check the material options

Two material options are described:

• Glass fiber type: ECR glass fiber can be used along with E-glass fiber when higher chemical resistance is needed. Ask whether your medium calls for this.
• Top coat: A colored or semi-transparent top coat can be applied to resist UV light and protect the exterior. This matters for outdoor installations.

Dual laminate scrubbers are also listed in the product range. If your process needs a dual laminate construction, state that in your enquiry.

5. Define the supply scope

An FRP scrubber package can cover more than the vessel. The description lists:

Internals and system components: internal and external piping, spray banks, support beams, mist filters, packing, distribution systems and ducting. These can be made in many shapes and configurations.

Exterior accessories: ladders, platforms, railings, walkways, drainage, protection liner and electrostatic discharge.

The description also says the supplier designs, produces and installs exterior equipment. Write down exactly which items you want quoted, and whether you need installation, so that competing offers cover the same scope.

6. What this guide does not confirm

Summary checklist

• Is the application one of those listed (FGD, gas cleaning, chemical processing, pollution control, incineration, power generation, water treatment, liquid storage)?
• Have you provided medium, temperature, flow rate, pressure, earthquake, wind load and climate data?
• Do you need ECR glass for higher chemical resistance, or a UV-resistant top coat?
• Is a dual laminate construction needed?
• Which internals and exterior accessories are in scope, and is installation included?
• Have price, lead time and any required certifications been confirmed in writing?
