Extrusion-Wound Construction
Houston PolyTank builds PP and HDPE cylindrical tanks for industrial and municipal systems that need long‑term reliability. Our extrusion‑wound design resists corrosion and delivers a more dependable alternative to steel, stainless, fiberglass, and rotomolded plastic tanks in aggressive, high-duty applications.
Our extrusion‑wound cylindrical tanks are engineered for:
Fully custom applications and configurations
Uniform wall thickness for structural stability
Strong resistance to chemical attack
Proven reliability in high‑stress applications
Repairable construction in the field
This construction method is what sets Houston PolyTank apart in PP and HDPE cylindrical tank manufacturing.
10,000 gallon polypropylene slope-bottom tanks
Engineered for Harsh Chemicals and High Temperatures
These tanks are designed for conditions where traditional materials often fail. Typical uses include:
- Chemical storage and processing
- High‑specific‑gravity materials
- Industrial wastewater and treatment systems
- Continuous‑duty operations
- Corrosive and high‑temperature environments
- Municipal and industrial containment systems
- Reactor, flow battery, and mixing tank applications
The result is consistent performance in the most demanding service conditions.
Material Selection for Performance and Temperature
We'll select the right material for your specific chemical and operating conditions.
- High-density polyethylene (HDPE) for applications up to 120°F
Polypropylene (PP) for high-temperature applications:
- up to 180° F for chemical applications
- 200° F for water and hot air (ductwork applications)
Material selection is based on chemical compatibility, temperature, specific gravity, structural loading, and environment to ensure long‑term reliability from day one.
Structural Strength and Wall Thickness
Wall thicknesses range from 0.5 inches to 2.5 inches, delivering:
- High structural rigidity
- Excellent impact resistance
- Superior chemical resistance
- Longer service life than steel, fiberglass, and rotomolded tanks
This is engineered infrastructure. Not a commodity tank.
Tank Configurations and Capacities
Houston PolyTank cylindrical tanks are available in vertical and horizontal configurations to support a wide range of industrial and municipal applications.
Our tanks are available with flat, open, cone, or recessed tops and flat, sloped, or cone bottoms. Sloped-bottom designs promote full-drain service, helping achieve 100% clean-out, minimize residue buildup, and reduce cleaning and maintenance time in harsh chemical and high-duty applications.
Vertical Cylindrical Tanks
Industry standard for chemical processing, storage, and wastewater systems; engineered for maximum structural efficiency and long‑term reliability.
Horizontal Cylindrical Tanks
Ideal for height‑restricted areas, skid‑mounted systems, mobile equipment, and trailer‑mounted service; designed for stability and uniform load distribution.
Capacities
Standard cylindrical tanks range from 50 to 30,000 gallons, with larger custom and pressure‑rated designs available based on engineering review.
