To select an FRP storage tank for an agricultural operation, first define what you will store, the volume you need, and the tank’s installation and operating conditions. Then confirm that the tank’s resin, structure, fittings, and support design are suitable for the stored material and site. FRP tanks can be considered for water, fertilizer solutions, and other agricultural liquids, but no single tank specification is appropriate for every liquid or location.
At Shunhao, we recommend sharing the application details before requesting a quotation. This helps a supplier assess material compatibility and propose a configuration based on the actual duty rather than capacity alone. Use the guide below to prepare a clear specification and compare suppliers on the details that affect safe, practical operation.
This guide is for agricultural distributors, farm operators, irrigation contractors, project engineers, and procurement teams sourcing tanks for commercial or industrial use. It is particularly useful when you are comparing FRP with other tank materials, planning a new storage installation, or replacing a tank without a complete record of its original specification. Smaller farm installations can use the same selection principles, even if the purchasing process is less formal.
The guidance is intended for preliminary selection, not a substitute for engineering review. Final design should account for the stored liquid, local environmental conditions, applicable project requirements, and the tank’s installation method. For unusual chemicals, elevated temperatures, or demanding structural conditions, confirm the design with a qualified tank supplier or engineer.
An FRP storage tank is a vessel made from fiber-reinforced plastic, typically using glass reinforcement within a resin matrix. The resin and reinforcement work together to form the tank structure, while the specific construction and design determine its suitability for a given service. Depending on the design, tanks may be manufactured in different shapes, capacities, orientations, and configurations.
In agriculture, a tank’s job may be to hold irrigation water, collect or buffer process water, or store a liquid used in a farm operation. The selection must consider more than the nominal volume: liquid chemistry, fill and discharge arrangements, cleaning needs, external loads, and access for inspection can all affect the required specification. A tank should be selected for its intended service, not simply because its material is described as corrosion-resistant.
Water storage is often a straightforward starting point, but water quality and site conditions still matter. Fertilizer solutions and other agricultural liquids can vary in composition and concentration, so compatibility depends on the actual formulation, temperature, and exposure conditions. Before ordering, provide the supplier with the product name and, where available, its safety data sheet or relevant chemical details.
Ask which resin system and construction are proposed for your service, and request confirmation of any operating limits relevant to the application. Do not assume that one resin is suitable for every fertilizer or chemical. If the liquid changes over time, list the full range of products that may be stored, including cleaning agents used during maintenance.
Tank orientation and support requirements should reflect the available space, foundation, access route, and connection layout. A vertical tank may use floor area differently from a horizontal design, while an elevated installation can introduce structural and anchoring considerations. Confirm the proposed tank dimensions, empty and operating loads, support arrangement, and access requirements before finalizing the site plan.
Specify the needed nozzles, manways, vents, drains, level indication, and overflow arrangements. Their size, position, and material should suit the connected pipework and the task operators need to perform. A drawing reviewed by both the buyer and supplier can help identify clashes before manufacturing begins.
Estimate demand over the period the tank must cover, then distinguish usable volume from nominal capacity. For example, if an operation uses 5 m³ of water per day and wants a three-day reserve, the basic reserve calculation is 15 m³. This is an illustrative calculation, not a universal design recommendation; the final tank size should also account for delivery schedules, seasonal demand, replenishment reliability, and the usable operating range.
Shunhao supply professional and honest service.
Ask the supplier to clarify how the quoted capacity is defined and whether the proposed volume includes space that must remain unfilled. Avoid selecting a tank solely from its catalogue capacity when the process requires a specific usable volume. If demand varies, provide both typical and peak-use estimates.
Record the liquid’s name, concentration or composition, expected temperature, and how often the tank will be filled, emptied, or cleaned. Note whether the tank will be installed indoors or outdoors and whether it may face wind, sunlight, frost, or other local environmental conditions. The supplier needs these details to evaluate the tank design and the installation requirements.
Also document the foundation, access for delivery and lifting, nearby equipment, and pipe loads that may be transferred to the tank connections. Do not assume that a tank designed for one support arrangement can be installed on another without review. Where site loads or local codes apply, have the project team confirm them before purchase.
Prepare a simple process sketch showing inlet, outlet, drain, overflow, vent, and level-measurement points. Include connection sizes and locations where known, and identify which components are supplied with the tank and which are provided by others. This reduces ambiguity in quotations and makes it easier to compare suppliers on an equivalent basis.
Consider how operators will inspect and clean the tank, and whether the design provides suitable access for those tasks. If the tank will serve a dosing or irrigation system, check the connection arrangement against the pumps, valves, and pipework. Clear operational requirements at the specification stage can prevent avoidable site modifications.
Request a written quotation that identifies capacity, dimensions, orientation, proposed resin or material system, fittings, support requirements, and included accessories. Ask for a general arrangement drawing and any design or installation information relevant to your project. Confirm what the supplier needs from you to validate chemical compatibility and structural requirements.
| Selection area | What to confirm | Why it matters |
|---|---|---|
| Stored liquid | Composition, concentration, temperature, and cleaning chemicals | Helps assess material compatibility |
| Capacity | Nominal and usable volume, operating range, and demand assumptions | Reduces the risk of undersizing or over-specifying |
| Installation | Foundation, supports, access, environmental exposure, and delivery route | Connects the tank design to real site conditions |
| Connections | Locations, sizes, materials, vents, drains, and instrumentation | Supports smoother integration with the process |
| Commercial scope | Accessories, packaging, documentation, delivery terms, and schedule | Makes supplier quotations easier to compare |
Ask how the supplier reviews application requirements, confirms drawings, handles changes, and communicates production and delivery milestones. Clarify the inspection and documentation included in the order rather than relying on broad descriptions such as “high quality.” Request applicable product information and installation guidance that your project team can review before shipment.
Price, minimum order quantity, and lead time depend on the tank’s size, design, materials, fittings, order scope, and delivery destination. A custom configuration may involve different commercial terms from a standard design, so ask for a project-specific quotation. Compare the complete scope, including transport and installation responsibilities, rather than treating the tank price as the only cost.
The right FRP storage tank for an agricultural application is the one specified around the stored liquid, usable capacity, operating conditions, site, and required connections. Start with a demand estimate, document the chemical and environmental conditions, and have the supplier review the proposed configuration before placing an order. For the illustrative reserve calculation in this guide, 5 m³ per day across three days gives 15 m³ before any project-specific allowances are considered.
To begin a discussion with Shunhao, prepare your required capacity, liquid details, installation location, preferred orientation, connection list, and target delivery schedule. We can use this information to discuss a suitable FRP tank configuration and identify the details that need confirmation before quotation. If some requirements are not yet known, share what you have and flag the open items for review.
