Frequently asked questions about HDPE pipe
What is HDPE pipe?
It is pipe made of high-density polyethylene. It is flexible, does not rust or corrode, and is joined by butt fusion or electrofusion, so the network is continuous and joint-free. GROUPPIPE polyethylene pipes are designed to exceed 100 years of continuous service.
Are PEAD and HDPE the same thing?
Yes. HDPE is the English acronym (high-density polyethylene) and PEAD is the Spanish one (polietileno de alta densidad). It is also known as polyethylene pipe.
What do SDR and PN mean?
SDR is the ratio between the outside diameter and the wall thickness: the lower it is, the thicker the wall and the more pressure the pipe can withstand. PN is the nominal pressure in kg/cm² with water at 20 °C. For example, a PE100 SDR 11 pipe is PN 16.
What is the difference between PE80 and PE100?
PE100 is a stronger resin: with the same wall thickness, it withstands more pressure. In SDR 17, for example, PE80 is PN 8 and PE100 is PN 10.
What lengths are they supplied in?
In straight lengths of 12 and 15 meters from 40 mm in diameter. From 20 to 125 mm, they are also supplied in coils of 50 to 200 meters, depending on the diameter and the SDR.
What standards do they meet?
AGP pipe for drinking water and ICL pipe for pressure sewers meet the IRAM 13485 standard and carry the IRAM Conformity Mark. UFP fire protection pipe has FM1613 certification, and OGA pipe for oil and gas complies with API 15 LE.
What information do I need to request a quote?
The diameter, the SDR or working pressure, the length in meters, the application (water, gas, sewers, mining, industry) and the delivery location. You can request it through the quote form or on WhatsApp at +54 9 11 7097-7473.
