Product Description
Product Overview
The SUNMORE Rotomolded Special-Shaped HDPE Water Tank is a custom irregular rotomolded plastic water tank manufactured using seamless one-piece thickened HDPE rotational molding. The tank body features integrated convex reinforcing ribs for superior pressure resistance. Custom configurations include special cone bottoms, square transitions, and multi-port reserved special shapes to accommodate specific installation space requirements. With excellent anti-corrosion, anti-aging, and leakproof performance, this tank is widely used in rural water supply, farm irrigation, sewage purification, environmental dosing, and underground confined installation projects.
Key Features & Benefits
  • One-Piece Rotomolded Thick HDPE Body, Zero Leakage Risk: The entire special-shaped tank is formed in a single rotational molding process without splicing or welding gaps. Thickened modified HDPE walls prevent liquid seepage, making it suitable for long-term storage of clean water, sewage, and chemical liquids.
  • Integrated Circumferential Reinforcing Rib Design, Outstanding Anti-Pressure Performance: Evenly distributed convex reinforcing ribs are molded together with the tank body, significantly improving radial compression resistance. The tank can withstand underground backfill soil pressure and internal liquid gravity without bulging or deformation during full-load long-term operation.
  • Anti-UV & Acid-Alkali Corrosion Resistant Raw Material Formula: HDPE raw material is blended with UV stabilizers and anti-corrosion additives, providing resistance to long-term outdoor sunlight aging and erosion from domestic sewage, agricultural fertilizer liquids, and weak acid-base reagents. Ideal for outdoor and underground buried installations with extended service life.
  • Comprehensive Customization For Engineering Projects: Customize tank capacity, redesign irregular outer contours, optimize reinforcing rib distribution, add multi-spec reserved pipe ports, match custom shell colors, and carve brand logos on the tank surface to meet special installation demands for sewage, farmland, and underground projects.

Frequently Asked Questions
Can this special-shaped tank bear backfill pressure when buried underground?
Integrated thick reinforcing ribs are distributed all over the tank body, which evenly disperses soil backfill pressure, effectively preventing bulging and cracking under buried working conditions.
Can the irregular outline and all pipe ports be formed in one step without post-processing?
We adjust the mold cavity according to customer drawings to realize special outline and all inlet/outlet ports integrated molding, no need for secondary cutting and drilling after demolding.
What customization can be provided for environmental and agricultural engineering bulk orders?
We customize tank internal volume, redesign irregular outer contour, adjust the layout and quantity of reinforcing ribs, add various reserved pipe ports, change tank shell color and print enterprise brand logos on the surface.
