Ultra-high stress-crack-resistant PE100-RC (Resistant to Crack) pressure piping systems engineered specifically for modern trenchless installation methods, including Horizontal Directional Drilling (HDD), pipe bursting, sliplining, and sandbed-free installation in rocky ground. Certified in accordance with PAS 1075 (Publicly Available Specification) and ISO 4427 across Type 1 (single-layer solid RC), Type 2 (multi-layer co-extruded RC with color-coded inspection layer), and Type 3 (RC core with outer protective scratch-resistant polypropylene/polyethylene shield). Formulated with modified high-stress copolymer resins providing over 10 times higher resistance to slow crack growth than standard PE100, completely eliminating the risk of notch-induced cracking caused by sharp rocks, gravel backfills, and tensile installation pulling stresses. Available from OD 63mm to 1000mm in pressure classes PN10, PN16, and PN25.

PE100-RC represents the peak of thermoplastic resin engineering for civil infrastructure, specifically developed to solve point-loading and external notch notch propagation failures governed by DIN PAS 1075 and ISO 4427-2. Unlike conventional PE100 materials that require a minimum of 100 to 500 hours in the Full Notch Creep Test (FNCT), PE100-RC compounds withstand continuous test durations exceeding 8,760 hours (one full calendar year) at 80°C under 4.0 MPa stress in a 2% Arkopal surfactant bath without failure. Furthermore, under the Point Loading Test (Dr. Hessel test), PE100-RC exhibits continuous resistance to localized point-stress concentrations over 10,000 hours. This exceptional molecular toughness prevents microscopic surface scratches and deep gouges sustained during pull-back operations from developing into through-wall structural fractures.
From a construction economics standpoint, PE100-RC completely revolutionizes trenchless civil utility deployment. In traditional open-trench pipe laying, contractors must excavate oversized trenches, import expensive graded silica sand for pipe bedding and haunching, and haul away native spoil. PE100-RC completely eliminates the need for imported sand bedding, allowing contractors to backfill directly with native excavated rocky soil and gravel up to 63mm particle size. For trenchless installations using Horizontal Directional Drilling (HDD) under busy urban expressways, riverbeds, and railway lines, PE100-RC Type 3 with an integrated peelable protective outer jacket guarantees that severe surface scratching down to 20% of pipe wall thickness does not compromise the internal pressure-bearing core.
In Iraq’s challenging geotechnical environment—ranging from hard limestone and flint deposits in Kurdistan, the Western Desert of Anbar, to congested utility underground networks in central Baghdad—PE100-RC is the engineered standard for high-risk projects. Where trenching causes unacceptable traffic chaos or where rocky terrain makes sand bedding economically unfeasible, PE100-RC delivers certified 100-year structural reliability under extreme mechanical loading and ground settlement.
While both materials share the same 50-year long-term hydrostatic strength (MRS 10 MPa), PE100-RC is formulated with specialized polymer chain branching that provides over 10 times higher resistance to slow crack growth (SCG), making it virtually immune to cracking from surface notches and stone point-loads.
No. PE100-RC utilizes identical welding parameters, temperatures (210°C–225°C), and heating times as conventional PE100 according to DVS 2207-1. It is 100% compatible for butt fusion and electrofusion jointing directly to standard PE100 pipes and fittings.
Standard PE100 mandates a 100mm–150mm surrounding sand envelope to protect against stone point-loads. Under PAS 1075, PE100-RC is certified for direct backfill using excavated native rocky soil (up to 63mm grain size), eliminating sand procurement and hauling expenses.
