PP Aquaculture Tanks: Manufacturing Process and FAQs
Why Choose PP Tanks?
In modern aquaculture, the choice of containers directly affects farming efficiency and survival rates. PP tanks (Polypropylene Aquaculture Tanks) are gradually replacing traditional metal or fiberglass tanks for several reasons:
• Safe and Eco-Friendly: PP material is non-toxic, corrosion-resistant, and suitable for long-term fish and shrimp farming.
• Highly Durable: PP tanks are rust-proof and aging-resistant, with a typical lifespan of 10–15 years.
• Customizable: Diameter, height, overflow outlets, reinforcement ribs, and drainage systems can be customized according to farm scale.
Compared to metal tanks, which easily corrode, or fiberglass tanks, which can crack, PP tanks combined with thermoplastic welding technology (thermoplastic welding machine for PP aquaculture tanks / poly tank welder) are lighter, more durable, and environmentally friendly.

PP Tank Manufacturing Process
The core of PP tank manufacturing is precise cutting + high-quality welding, ensuring seamless, leak-proof tanks.
1. Sheet Cutting and Machining
PP sheets are cut and processed using cutting machines and CNC routers, with assembly features like holes and chamfers added.
2. Rolling and Cylinder Formation
Side sheets are rolled into cylinders, ensuring accurate dimensions for welding.
Cylinders are welded along longitudinal seams to form a high-strength structure.
4. Extrusion and Hot Air Welding
• Extrusion Welding (plastic water tank welding machine/poly tank welder): Welds the bottom and cylinder firmly for complete sealing.
• Hot Air Welding: Preheats, surface-activates, and reinforces small areas to ensure long-term leak-proof performance.
These processes create seamless, integrated tanks, which are safer and more durable than bolt or adhesive assembly.

Frequently Asked Questions (FAQ)
Q1: How long do PP tanks last?
A1: Under normal aquaculture conditions, the lifespan is typically 10–15 years.
Q2: Can PP tanks be customized in size and structure?
A2: Yes. Diameter, height, outlet positions, and reinforcement ribs can be customized to meet your farm’s needs.
Q3: Are PP tank welding processes reliable?
A3: We use international standard thermoplastic welding technology, with seam strength comparable to the base material, ensuring safety and reliability.
Q4: What are the advantages compared to fiberglass or metal tanks?
A4: PP tanks are rust-proof, crack-resistant, lightweight, corrosion-resistant, easier to transport and install, and environmentally friendly.
Q5: Is transportation and installation complicated?
A5: PP tanks are lightweight, can be transported as a whole, or welded and assembled on-site to suit different farm conditions.

Conclusion & Call to Action (CTA)
As aquaculture scales up, PP tanks combined with advanced thermoplastic welding technology have become the ideal choice for farms. They are durable, eco-friendly, customizable, and maintain long-term sealing performance and structural strength.
