Materials and Structure

Material: Mainly composed of glass fiber and resin, this combination gives the water tank the characteristics of light and hard weight, non-conductive, high mechanical strength, and corrosion resistance. The resins used are usually unsaturated polyester, epoxy resin, and phenolic resin matrix, while glass fiber plays a role in enhancing strength.

Structure: It is generally assembled from panels of different sizes and thicknesses made by hydraulic hot pressing. Common panel sizes include 2mx1m, 1m × 1m, 1m × 0.5m, 0.5m × 0.5m, etc., with a thickness between 4-16mm. These panels are connected together by a steel frame and rubber gaskets to form a complete water tank.

Core Performance

1. Material advantages

The density is 1/4-1/5 of carbon steel, and the tensile strength is close to carbon steel, combining lightweight and high load-bearing capacity.

Strong corrosion resistance, able to resist acid, alkali, salt, and oil erosion, suitable for harsh environments such as chemical and food industries.

2. Functional characteristics

Excellent insulation performance, reducing water temperature fluctuations, suitable for agricultural irrigation and constant temperature demand scenarios.

No leakage, no rust, water quality meets national drinking water standards, and has passed hygiene and safety testing.

Applications

Civil buildings: widely used in residential, apartment, hotel, school, hospital and other civil buildings for storing domestic water, fire water, etc., providing safe and reliable water sources for residents and users.

Industrial Fields: In the industrial field, it can be used to store various industrial water, raw material liquids, cleaning liquids, etc. in chemical, pharmaceutical, food and beverage, electronic and other industrial production to meet the water needs in the production process. At the same time, due to its corrosion resistance, it can adapt to various harsh industrial environments.

Agricultural irrigation: It can be used for agricultural production such as farmland irrigation, orchard irrigation, greenhouse, etc., to store rainwater or irrigation water, provide sufficient water for crops, improve irrigation efficiency and water resource utilization.

Rainwater collection: used to collect and store rainwater, achieve the recycling and utilization of rainwater, and can be used for non drinking water purposes such as watering flowers, trees, flushing toilets, car washing, etc., which helps to save water resources and reduce water costs.

Sewage treatment: In sewage treatment plants or industrial wastewater treatment systems, GRP water tank can be used as regulating tanks, sedimentation tanks, clear water tanks, etc., to store and treat sewage, helping to achieve purification and standard discharge of sewage.

Installation Process of Modular Panel Water Tanks

1. Preparation before installation

Basic construction

Ensure that the installation ground is flat and the horizontal error is ≤ 0.5cm. The channel steel base should be welded into a frame that matches the bottom plate of the water tank. The welds should be uniform and the size error should be controlled within ± 0.5cm.

Clean up the debris on site and reserve enough operating space.

Material inspection

Check the quantity and quality of base steel components, bolts, sealing strips, tension bars and other accessories to ensure that there are no defects.

2. Base installation

Fixed channel steel frame

Fix the welded channel steel base on the foundation with expansion bolts or cement piles to ensure no shaking.

3. Bottom plate installation

Bottom panel splicing

Arrange the bottom plates in the order of single board numbers, embed sealing strips between the plates, and evenly tighten them 3-4 times with φ 10 bolts to avoid cracking the plates.

Connected to the base

By fixing angle iron to lock the bottom plate and channel steel base, the overall stability is enhanced.

4. Side panel installation

Side panel assembly

Erect the side plates layer by layer according to their numbers, ensuring they are perpendicular to the bottom plate (at a 90° angle). Add sealing strips between the plates and fix them with bolts.

Reinforcement treatment

The connection between the side panel and the bottom panel needs to be reinforced with angle iron or iron sheets to prevent separation.

5. Internal reinforcement

Reinforcement installation

Cut the tie bars according to the size of the water tank, fix them with threaded bolts at the cross intersection inside the box, adjust the error to the minimum, and ensure that the tie bars are balanced with the box.

Plug sealing

Install plugs at the 14 corners of the joint between the bottom plate and the side plate, and apply enough glass glue to seal.

6. Top plate installation

Cover plate fixation

Lay the top plate in parallel in order, tighten the bolts evenly, and avoid over tightening causing deformation of the rubber strip or over loosening causing water leakage.

7. Pipeline connection and sealing test

Connection of inlet and outlet

Connect the inlet pipe, outlet pipe, and drain pipe, install a filter (optional), and ensure that the interface is sealed without leakage.

Comprehensive testing

After injecting water, check all joints and bolts for leaks, and if necessary, apply glass glue.

8. Acceptance

Acceptance criteria

The water tank body is free of deformation, well sealed, the pipeline is unobstructed, and the horizontal error meets the requirement.

Maintenance

Regular inspection

At least once a year, check the aging condition of the sealing strip, the tightness of the bolts, and the stability of the foundation.

Focus on checking the balance of the tension bars and whether there are cracks at the connection between the side plate and the bottom plate.

Cleaning and disinfection

Before the first use, thoroughly clean the inside of the water tank, drain the sewage, and rinse twice with clean water.

Clean at least twice a year, and after cleaning, open the drain valve to drain any remaining water to prevent bacterial growth.

Precautions

Avoid stacking heavy objects or conducting impact operations around the water tank to prevent deformation of the shell.

Antifreezing measures should be taken in winter to prevent internal icing from causing the water tank to rupture.

Attachment: Key operating tools and materials

Tools: Level ruler, wrench, welding machine, sealant gun, bolt fastener.

Consumables: 10 diameter bolts, silicone sealing strips, glass glue, antifreeze insulation material.

By standardizing installation and regular maintenance, the service life of fiberglass water tanks can be significantly extended and water quality safety can be ensured.
