Plastic Tanks & Process Equipment

Plastic tanks offer several significant advantages over fiberglass (FRP) and metal (steel) tanks, often making them the preferred choice for storage and transport:

• Corrosion resistance: Plastic tanks do not rust and, unlike metal tanks, are resistant to corrosion caused by water or chemicals.
• Lightweight & Easy Handling: They are significantly lighter than metal or FRP tanks, which makes transport, positioning, and installation considerably easier—often without the need for heavy equipment.
• Seamless construction: High-quality plastic tanks are often manufactured in a single piece (seamless) using the rotational molding process, which eliminates the risk of leaks at weld seams.
• Cost-effectiveness: They are generally less expensive to purchase than stainless steel or high-quality FRP tanks.
• Low maintenance: Due to the material properties, they do not need to be painted or protected against rust, which reduces long-term maintenance costs.
• Flexibility & durability: They are impact-resistant, UV-stabilized, and durable (often 20+ years), while possessing a certain degree of flexibility that can be advantageous in the event of ground movement.
• Environmentally friendly – plastic tanks can be fully recycled at the end of their service life

Our tanks made of thermoplastics, such as High-Density Polyethylene (HDPE), Polypropylene (PP), and Polyvinylidene Fluoride (PVDF) offer significant advantages over traditional metal or concrete tanks. These include superior resistance to chemicals and corrosion, low maintenance, lightweight design for easy installation, and high recyclability.

Our plastic tanks are manufactured from the following materials:

• PP-H Polypropylene homopolymer – temperature-resistant up to 115 °C
• PP-B Polypropylene block copolymer – up to 100 °C
• PE-HD High-density polyethylene – up to 80 °C
• PVC Polyvinyl chloride – up to 60 °C
• PVC-C Post-chlorinated polyvinyl chloride – up to 95 °C
• PVDF Polyvinylidene fluoride – up to 140 °C

Our tanks made of thermoplastics, are manufactured from homogeneous, spirally wound pipes with large diameters ranging from DN 850 to DN 4,500 mm. We primarily produce upright, i.e., vertical tanks, for which there is no limit on height. The maximum standard volume is 200 m³.

However, we also manufacture horizontal tanks; the choice depends on whether they are to be installed above ground or underground. Generally, the wall thickness of horizontal tanks is greater. The maximum diameter for horizontal tanks is 3.5 m, with lengths of up to 15 m. For larger underground storage volumes, we interconnect multiple tanks.

For the production of rectangular tanks, we employ a welding technique that requires no additional filler material; specifically, this involves vertical butt welding.

Cylindrical Process Tanks and Vessels feature conical bottoms, and their standard equipment includes agitators, heating and cooling coils, and aeration and spray systems.
