OctoPipe Your Specialist in Paste Fill Pipe Reticulation
OctoPipe is a dedicated supplier of paste fill pipe reticulation solutions for underground hard rock mining.
Through direct OEM relationships, independent factory quality assurance and managed distribution, we provide mines across Africa with reliable access to high-pressure Steel Wire Reinforced Composite Pipe (SRCP), Schedule 80 steel pipe and the supporting systems required to transport, install and monitor paste reticulation infrastructure. We provide direct shipping from the OEM to mine sites, supported by strategically located storage facilities across Africa in Johannesburg, South Africa; Gaborone, Botswana; Windhoek, Namibia; and Dar es Salaam, Tanzania.
Introduction
Technology
OctoPipe Steel Wire Reinforced Composite Pipe (SRCP) brings together the pressure capability of steel with the light weight, flexibility and corrosion resistance of polyethylene. Designed for on-level paste fill reticulation, it provides a smooth, low-friction bore, faster installation and safer underground handling while coupling directly to the steel systems mines already operate.
Third-party burst testing has demonstrated a safety factor of up to three times the rated working pressure, while the lightweight grooved system can significantly reduce installation time and installed cost compared with a steel-only system.
Relationship
Dwyka Mining Services is the exclusive distributor of OctoPipe™ SRCP and Schedule 80 steel paste pipe across Africa. Genuine high-pressure SRCP is produced by a limited number of manufacturers worldwide. Through direct OEM relationships, OctoPipe makes this specialised product more accessible and supports every shipment with independent quality assurance conducted by OctoPipe personnel at the point of manufacture.
The product range is supplied alongside Shurjoint XH-70EP high-pressure couplings and is also compatible with the Victaulic equivalent. These coupling systems have been used at major underground paste reticulation operations internationally, with references available on request.

Product Range
SRCP Paste Pipe
Steel Wire Reinforced Composite Pipe for on-level paste fill reticulation
OctoPipe™ SRCP combines a smooth PE100 HDPE bore with high-tensile steel wire reinforcement and a corrosion-resistant outer PE100 layer. The result is a lightweight, low-friction pipe system engineered for underground paste and backfill distribution where installation speed, safety and long-term durability matter. Available in 160mm and 200mm sizes, with 3.5 MPa, 7 MPa, 10 MPa and 12MPa pressure options.
Schedule 80 Steel Pipe
Seamless carbon steel pipe for high-pressure paste fill applications
OctoPipe™ also supplies cut-grooved A106B Schedule 80 steel pipe for sections of the paste system where steel remains the preferred solution, including borehole trunk lines and high static head applications. Pipe is available in 160mm and 200mm sizes and supplied with machined grooves for compatibility with high-pressure couplings.
Shurjoint XH-70EP Couplings
Extra heavy rigid grooved couplings for high-pressure paste fill systems
Shurjoint XH-70EP couplings are designed for demanding paste fill applications and are compatible with OctoPipe™ SRCP and steel pipe when EP cut-groove ends are used. They offer a high-pressure grooved connection standard across the reticulation system, helping mines simplify installation and maintenance while avoiding welding or hot work underground.
PackSafe™ Racking System
Safe storage and transport for paste pipe
The PackSafe™ racking system supports safer transport, handling and storage of both steel and SRCP pipe. Designed for layered pipe removal, dual-direction lifting and compact warehouse stacking, it helps improve logistics efficiency from delivery to installation.
OctoBracket Pipe Suspension
Rated suspension system for 200NB paste / backfill pipe
OctoBracket is a no-weld suspension solution designed specifically for underground paste and backfill pipe support. Rated to 500kg WLL, it provides a practical support option for 200NB pipe installations where durability and simplicity are required.
SmartPipe™ Pressure Monitoring
Integrated pressure monitoring for underground paste fill systems
SmartPipe™ combines a robust Schedule 80 pipe body with a flush-mounted 10 MPa pressure transmitter to provide real-time visibility into paste fill system performance. Available in DN150 and DN200 configurations, it integrates with Maestro Digital Mine paste monitoring solutions to help operators track pressure, identify changes in system conditions and support more informed operational and maintenance decisions.

Why Mines Choose OctoPipe™
Performance
OctoPipe™ SRCP helps improve stope fill efficiency through a smooth, low-friction internal bore that reduces friction losses compared to steel. This supports lower system pressures, improved paste movement and more efficient fill cycles underground.
Safety
At up to 75% lighter than Schedule 80 steel, SRCP is easier and safer to handle underground. This reduces manual handling strain and simplifies installation logistics in constrained mining environments. The pipe has also been third-party burst tested to 18 MPa with no rupture or leakage.
Faster Installation
Grooved EP cut-end connections eliminate the need for welding, hot work permits and specialist installation equipment. Mines can install OctoPipe™ systems significantly faster than steel-only alternatives while using a consistent grooved coupling standard across both SRCP and steel sections.
African Supply Continuity
Dwyka holds exclusive distribution rights for OctoPipe™ SRCP across Africa, with in-country stock and planned or active supply points in Johannesburg, Gaborone and Mwanza (Tanzania), as well as direct-to-minesite supply options.
Quality Assurance
Pipe manufactured overseas is often released on the manufacturer’s own inspection. OctoPipe adds an independent quality-assurance layer at the point of manufacture. Our personnel inspect the product, witness testing and supervise packing and loading before shipment. A QA report is supplied with every shipment.
Dimensional Inspection
One pipe in every twenty is measured with calibrated instruments against a controlled drawing. A single non-conformance triggers further QA inspections.
Marking and Release
Every pipe carries its full part number. Batch-checked pipes receive QC stickers signed and dated by the inspector
Pressure and Burst Testing
Hydrostatic and burst testing is carried out at the manufacturing plant for each batch order and witnessed by OctoPipe personnel to confirm performance against the rated working pressure.
Loading Supervision
The shipment is reconciled against the packing list. Fabric slings, capped ends and strapped bundles are used to support safe unloading and product protection.
Callout: QA report supplied with every shipment.
Callout: 3× safety factor.
Supply and Logistics
OctoPipe coordinates distribution and freight from the manufacturing plant through to regional supply points or direct to the mine site. Packing, documentation and loading are managed to support safe handling and a clear quality record on arrival.

FAQs Where OctoPipe™ Fits in the Paste System
OctoPipe™ SRCP is ideally suited to on-level paste fill arm distribution, where reduced weight, fast installation and corrosion resistance provide a clear operational advantage. In these sections, the lower handling weight and grooved connection system help accelerate rollout while improving underground practicality.
For borehole trunk lines and high static head sections, Schedule 80 steel may remain the preferred solution depending on system design requirements. Because OctoPipe™ uses the same grooved coupling philosophy across SRCP and steel, mines can transition seamlessly between the two materials across the reticulation network.
-
SRCP stands for Steel Wire Reinforced Composite Pipe. It is constructed using an inner PE100 HDPE layer, a cross-helically wound high-tensile steel wire reinforcement layer and an outer PE100 HDPE layer. The steel wire provides pressure strength, while the HDPE layers offer corrosion resistance, low friction and reduced maintenance requirements.
