Product Features
High Corrosion Resistance: PE material has excellent chemical stability, resisting the erosion of acids, alkalis, salts, and other chemicals, allowing for long-term stable operation in corrosive environments.
Stable Structure: The winding process gives the tank high strength and rigidity, enabling it to withstand significant pressure and weight without easily deforming or cracking.
Good Sealing: The tank body is welded, ensuring excellent overall sealing and effectively preventing leakage of stored media and the intrusion of external contaminants.
Long Service Life: PE material has good aging resistance; under normal operating conditions, PE winding tanks can last for more than 15 years and are recyclable.
Easy Installation and Maintenance: PE winding tanks are lightweight, easy to handle and install, and have a smooth surface that is not prone to scaling, resulting in low cleaning and maintenance costs.
Comparison with Rotomolded Storage Tanks
|
Characteristic |
PE spiral wound tank |
PE rotational molding tank |
|
Molding process |
Spiral winding and welding of strip sheet |
Resin powder is rotated, heated and melted in a mold to form the final product |
|
Size range |
Extra-large sizes (large diameter and length) are possible. |
Sizes are limited due to mold requirements and heating uniformity constraints. |
|
Structural Features |
Spiral welded seam, seamless construction |
Truly one-piece molding, without any seams. |
|
Strength characteristics |
Strong resistance to external pressure and negative pressure, superior rigidity |
Good overall toughness, and excellent impact resistance. |
|
Price Trends |
Large tanks offer better value for money |
Small and medium-sized tanks have advantages; the cost of large tanks is soaring. |
|
Shape restrictions |
Typically a horizontal cylindrical shape |
Various shapes (square containers, irregularly shaped cans, etc.) |
