1. Product Overview
High-Performance Polyethylene Piping Solutions for Water, Gas, Industrial and Infrastructure Applications
Be’lyz Group supplies high-performance HDPE PE100 and PE100-RC pipes and compatible fittings for potable water transmission and distribution, natural gas networks, industrial pipelines, wastewater infrastructure, agricultural irrigation and demanding underground installation projects.
Our product portfolio includes conventional PE100 pressure pipes and advanced PE100-RC piping systems engineered for enhanced resistance to slow crack growth, localized point loads and installation-related mechanical stresses.
PE100 and PE100-RC Material Performance
PE100 is a high-performance polyethylene material grade with a Minimum Required Strength (MRS) classification of 10 MPa, providing excellent corrosion resistance, flexibility, hydraulic performance and long-term reliability in pressure piping applications.
PE100-RC (Resistant to Crack) combines the established performance characteristics of PE100 with enhanced resistance to slow crack growth. This makes it particularly suitable for demanding installation methods, including horizontal directional drilling (HDD), pipe bursting and selected trenchless or reduced-bedding applications, subject to engineering assessment.
PE100-RC does not automatically provide a higher pressure rating than conventional PE100 pipes of the same diameter, SDR and design conditions.
PE100-RC Pipe Configurations — Type 1, Type 2 and Type 3
Be’lyz Group supports project-specific sourcing of PE100-RC pipes in three established construction configurations:
Type 1 — Single-Layer Solid-Wall PE100-RC Pipes
Homogeneous pipes manufactured from PE100-RC material throughout the pressure-bearing pipe wall, providing enhanced resistance to slow crack growth without requiring an additional protective jacket.
Type 2 — Coextruded Multilayer PE100-RC Pipes
Dimensionally integrated two-layer or three-layer pipe constructions incorporating PE100-RC materials, designed to combine pressure-pipe performance with application-specific layer configurations.
Type 3 — PE100-RC Pipes with Additional Protective Jackets
PE100-RC carrier pipes equipped with a supplementary external protective jacket, commonly made from polypropylene (PP), providing additional protection against installation-related surface damage.
The Type 1, Type 2 and Type 3 designations describe pipe construction rather than pressure classes. The applicable structural design, pressure-bearing wall thickness and product certification must be verified for each configuration.

8. Installation Methods & Engineering Considerations
Engineered Installation Solutions for Conventional and Demanding Pipeline Projects
PE100 and PE100-RC piping systems support a range of installation methods for water transmission, gas distribution, industrial infrastructure and underground utility networks.
Selection of the appropriate pipe configuration and installation technique depends on ground conditions, operating requirements, external loads, pipe dimensions and project-specific engineering assessments.
8.1. Conventional Open-Trench Installation
Open-trench installation is widely used for polyethylene pressure pipelines in municipal and industrial infrastructure.
Proper trench preparation, bedding, pipe positioning, sidefill and backfilling are essential to support long-term pipe performance.
Engineering considerations include:
- Trench width and installation depth.
- Bedding and surrounding soil characteristics.
- Compaction and backfill requirements.
- Traffic loads and external ground pressure.
- Pipe deflection and allowable deformation.
- Protection against sharp objects and localized point loads.
PE100-RC pipes may offer additional resistance to slow crack growth under demanding installation conditions. However, their use does not eliminate the need for an approved installation design.
8.2. Horizontal Directional Drilling (HDD)
Horizontal directional drilling enables the installation of pipelines beneath roads, rivers, railways and other obstacles without continuous open excavation.
PE100-RC pipes are particularly relevant for selected HDD projects because of their enhanced resistance to slow crack growth.
Key engineering parameters include:
- Maximum installation pulling force.
- Minimum allowable bending radius.
- Borehole geometry and ground conditions.
- Pipe wall thickness and SDR.
- Surface damage and abrasion exposure.
- Joint integrity during installation.
Type 1, Type 2 and Type 3 PE100-RC constructions may be evaluated according to the required mechanical protection and installation conditions.
8.3. Pipe Bursting & Pipeline Rehabilitation
Pipe bursting is a trenchless rehabilitation technique in which an existing pipeline is fractured or displaced while a replacement pipe is installed along the original alignment.
PE100-RC pipes may be selected for suitable projects involving localized mechanical stresses and challenging installation environments.
The design must consider pulling loads, existing pipeline material, surrounding utilities, ground displacement and the selected pipe construction.
Additional protective jackets may be considered where installation-related surface damage is a significant concern.
8.4. Ploughing & Reduced-Bedding Installation
Selected PE100-RC systems may be considered for engineered ploughing, narrow-trench and reduced-bedding installation methods.
These methods can reduce excavation requirements under suitable site conditions.
However, their suitability depends on the approved pipe system, soil characteristics, external loads, installation equipment and applicable technical guidance.
The enhanced slow crack growth resistance of PE100-RC does not automatically authorize installation without bedding or other protective measures.
8.5. Thermal Expansion & Pipe Movement
Polyethylene piping systems exhibit temperature-dependent dimensional changes and mechanical behavior.
Engineering design must consider thermal expansion and contraction, pipe restraint, anchor locations, bending requirements and operating temperature.
Above-ground installations may require additional assessment of UV exposure, pipe support spacing, thermal movement and mechanical protection.
8.6. Pressure Surge & Hydraulic Design
Pressure pipeline design must account for normal operating pressure, transient pressure events, pump operation and system shutdown conditions.
Relevant considerations include:
- Maximum operating pressure.
- Pressure surge and water hammer.
- Pipe SDR and material classification.
- Operating temperature.
- Design coefficient and service conditions.
- Joint and fitting pressure compatibility.
The selected pressure classification must comply with the applicable product standards and engineering requirements.
8.7. Installation Quality & Joint Inspection
Installation quality plays a critical role in the long-term performance of polyethylene piping systems.
Depending on the project, quality control activities may include:
- Verification of pipe and fitting identification.
