Characteristics & Advantages

High quality material: SUS304 stainless steel plate is generally used, with stable physical and chemical properties, no pollution to water quality, and can ensure clean and hygienic water quality, meeting the national OCr18Ni19 hygiene inspection standard.

Appearance and Structure: Stamped, high strength, light weight, neat and elegant appearance. The evenly distributed stainless steel reinforcement inside the box ensures even and reasonable pressure bearing of the box. The unique structure not only ensures the maximum pressure bearing needs of the box, but also reduces the material thickness, meeting the requirements of aesthetics and practicality.

Good corrosion resistance and sealing: The surface has a dense oxide layer, with superior corrosion resistance and good sealing performance, which can effectively prevent secondary pollution of water quality and extend the service life of the water tank.

Strong impact resistance and earthquake resistance: With high impact resistance and strong earthquake resistance, it can adapt to different installation environments and usage conditions.

Convenient construction: Standard stamping plates come in specifications such as 1000 × 1000, 1000 × 500, 500 × 500mm, and can be assembled freely. They can be assembled and welded on site without the need for lifting equipment, making construction convenient and fast.

Manufacturing Standards and Production Processes

Manufacturing standards: Generally following the national building standard 12S101 design drawings, there are strict regulations on the materials, structure, welding, dimensions, and other aspects of the water tank to ensure its quality and performance.

Production Process

Material cutting: According to design requirements, stainless steel plates are cut into suitable sizes and shapes using equipment such as plasma cutting machines and electric scissors.

Stamping forming: Use stamping equipment to press the cut stainless steel plate into plates with certain concave and convex shapes to increase the strength and rigidity of the water tank.

Welding assembly: Using argon arc welding machines and other equipment, the stamped plates are welded and assembled to form the main structure of the water tank. During the welding process, the quality of the welds must be ensured, without defects such as virtual welding, slag inclusion, or bubbles.

Internal reinforcement installation: Stainless steel reinforcement is installed inside the water tank to enhance its pressure bearing capacity. The position and quantity of the reinforcement are designed reasonably according to the size and capacity of the water tank.

Attachment installation: Install accessories such as water inlet, outlet, overflow outlet, sewage outlet, escalator, manhole, etc. of the water tank to ensure that all components are firmly connected and well sealed.

Full water test: After the water tank is made, fill it completely with water. After 2-3 hours, use a hammer lead weighing 0.5-1.5 kilograms to lightly tap along the weld seam about 150 millimeters on both sides to check for water leakage. If water leakage is found, it needs to be re welded and tested again until it is qualified.

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.
