Frequently asked questions
Short answers about GROUPPIPE polyethylene (HDPE) pipes and fittings.
What pipe diameters does GROUPPIPE® manufacture?
Pipes from 20 to 1,200 mm in outside diameter, with wall thicknesses of up to 90 mm, made at its manufacturing plant in San Luis.
What materials are the pipes made of?
Most are made of high-density polyethylene (HDPE), PE80 and PE100. For high temperatures and aggressive fluids, it also manufactures pipes in polypropylene (PP), cross-linked polyethylene (PEX), polyamide (PA11 and PA12) and polyvinylidene fluoride (PVDF).
Where is the manufacturing plant?
In the Parque Industrial Sur, San Luis (Calle 108 y 6). It stands on a 10,000 m² site, with four buildings totaling 2,400 m² and an installed capacity of 15,000 tons per year. The sales office is in Olivos, Buenos Aires province.
Which pipe is used for drinking water, and what standards does it meet?
The AGP Pipe, made of PE100+ polyethylene, for networks and aqueducts from DN 20 to 1,200 mm. It complies with the IRAM 13485 standard and holds the IRAM conformity mark and INAL approval.
What is the difference between solid pipe and corrugated pipe?
Solid pipe carries liquids and gases under pressure, such as drinking water or gas. Corrugated pipe carries flow by gravity (stormwater drainage, sewers and road crossings) and is also used as cable ducting.
How are HDPE pipes joined?
Solid pipes are joined by butt fusion or electrofusion, forming a continuous system with no joints. Corrugated pipes are joined with spigot and socket connections with anchors, or with a mechanical coupling.
What is the service life of HDPE pipes?
GROUPPIPE polyethylene pipes are designed to exceed 100 years of continuous service, with greater resistance than traditional materials.
What is the difference between PVC and HDPE?
Unlike PVC, HDPE offers greater flexibility, impact resistance and fusion capability (butt fusion and electrofusion), which results in a continuous, leak-free system.
Why use HDPE instead of concrete for drainage?
For underground and stormwater drainage, HDPE is much lighter, faster to install and more resistant to abrasion and chemical agents than traditional concrete pipes.
Does GROUPPIPE® provide advice on hydraulic calculations?
Yes. Its engineering department assists with calculating head losses and water hammer, and with diameter selection, to optimize each project. See Technical support.
