Technical reference for PE100 material grade, pressure design and pipe selection.
What is it?
PE100 is a polyethylene compound designation with Minimum Required Strength (MRS) of 10 MPa at 20 °C for 50 years — used to size HDPE pressure pipe wall thickness and PN class.
Designers specify PE100 when higher allowable stress enables thinner walls or higher pressure at the same outside diameter (SDR). Bukan Pipe produces PE100 HDPE pipes up to 630 mm OD for water, gas and industrial networks.
MRS is the long-term hydrostatic strength of the compound. PE100 (MRS 10 MPa) allows higher design stress than PE80 (MRS 8 MPa), which translates directly into PN class at a given SDR.
Standard Dimension Ratio (SDR) relates outside diameter to wall thickness. PN marked on water pipe is the nominal pressure at 20 °C reference temperature — not necessarily the field operating pressure.
| PE100 MRS | 10 MPa |
|---|---|
| PE80 MRS | 8 MPa |
| PN reference temperature | 20 °C for marked PN on supply pipe |
| Maximum OD (Bukan Pipe) | 630 mm single-wall HDPE |
Project-specific diameter, SDR and PN tables are issued on request.
Qualifying water supply production references INSO 14427-2. Gas projects may reference EN 1555, INSO 11233 and utility documents such as IGS-M-PL-014-1. Always follow the engineer's basis of design.
