TANKS MANUFACTURED BY HELICAL WINDING WITHOUT WELDING, IN ACCORDANCE WITH DVS2205

HDPE tanks

We have been designing and manufacturing HDPE and PP storage tanks for more than 40 years for companies that manufacture chemical products, warehouses, distributors, water treatment plants (WWTP, ETAP), etc.

Next, we invite you to discover our range of solutions for HDPE Tanks:

How do we manufacture our HDPE tanks?

We manufacture our PPA TANK tanks and accessories using helical extrusion technology in the manufacture of hulks to offer a reliable, safe and high-quality construction solution

This technology consists of the helical extrusion of HDPE or PP material on a steel mold that allows the construction of ferrules without welding. This makes our HDPE tanks more reliable and robust.

The combination of the translational movement of the extruder head with the rotational movement of the mold generates a helix of material that covers the surface of the mold.

The system is fully customizable and allows the extrusion of solid walls of any thickness, as well as reinforced walls with lightened sections. In the case of vertical tanks, we can also manufacture shells with variable thickness.

“We can extrude solid walls of any thickness and, in the case of vertical tanks, we can also manufacture shells with variable thickness”

The use of these lightened sections allows obtaining ferrules with high inertia and low weight, suitable for use in equipment subjected to vacuum or in horizontal and buried tanks. In addition, this system also allows the construction of fully monolithic double-wall ferrules (one piece).

As an additional advantage, the integrated co-extrusion system together with the main extruder allows the extrusion of homogeneous walls of two materials (weldable together), to improve visibility inside the tank (in the case of using a clear material inside) or add an inner lining with electro-conductive material.

The different components of the tank are assembled and joined together by extrusion welding.

In horizontal and buried tanks, we reinforce the lateral bottoms with brackets of the same material.

Types of HDPE Tanks available

The PPA TANK tanks, built in HDPE and PP, are designed according to the DVS 2205 standard. The use of specific calculation software allows us to offer a quick and efficient response to any design variation.

In the case of buried tanks or reservoirs, their design is carried out according to the ATV 127 standard for the calculation of burial forces.

We manufacture our PPA TANK tanks tailored to the needs of our customers and with different configuration possibilities

Examples of HDPE tank applications

Our PPA TANK deposits allow different possibilities taking advantage of the flexibility of the helical extrusion technology

HDPE vertical storage tanks with solid wall and variable thickness.

The possibility of manufacturing hulks (ferrules) of practically any thickness and varying it along its height, allows it to adapt to any design need with optimal use of the material.

The continuously non-welded wound ferrule ensures the structural integrity of the equipment.

Vertical HDPE tanks with monolithic double-wall ferrule and double bottom.

The possibility of first extruding a solid ferrule, then a structured (hollow) wall, and later, on said structured wall, another new solid ferrule, allows us to obtain a single monolithic piece.

This technology allows us to manufacture double-walled SQ tanks with an intermediate leak check chamber, thus making this type of tank meet the requirements specified in the MIE-APQ-006/007 standard for double-walled tanks, without the need for a bucket. additional retention.

These types of tanks are suitable for resisting vacuum conditions higher than conventional ones.

Vertical HDPE tanks with retention basin (according to DVS standard).

For cases of extreme safety, PPA TANK vertical tanks can be supplied with a retention basin with a capacity for 100% of the tank’s content in case of leaks or breakage of the main container

We built two tanks of different diameter. The main tank is introduced inside the retention basin, which has a larger diameter and a smaller height.

This type of tanks, according to MIE-APQ-006/007, are recommended to handle highly corrosive and dangerous fluids. and do not require an additional retention basin.

Reactors and vertical tanks for reagent preparation.

Our PPA TANK tanks can be equipped with supports for the placement of agitators or mixers, and internal baffles to be used as reactors or mixture and reagent preparation tanks

It is also possible to condition the upper covers for the addition of solid products.

Horizontal HDPE tanks.

Thanks to the use of structured walls in the construction of the ferrule with sufficient longitudinal inertia, we can build high-capacity horizontal tanks in thermoplastic materials.

Buried HDPE tanks

PPA TANK tanks with structured walls have an excellent weight-stiffness ratio. This makes them an excellent alternative for use as buried tanks for all kinds of applications

In addition, the use of structured walls makes these tanks double-walled with a sealing chamber, providing great reliability and safety.
