Ultralok High Impact PVC coupling
PVC CouplingDeveloped in-house by DPI Plastics, the patented Ultralok PVC-M coupling is an innovative product for the jointing of plain-ended pipes. This first-of-its-kind product, which is designed for applications of up to 16 bar pressure, is being aimed at both the civil and mining industries.With Ultralok, mining companies especially can reduce their costs by using this coupling with new pipes or by repairing existing piping systems - instead of utilizing a traditional Victaulic type coupling. The Ultralok mPVC coupling and components are fully-protected against corrosion. The design mechanism of Ultralok is different to any other product on the market in terms of its robustness and gripping nature. The clamping mechanism is unique because it is manufactured from high-impact PVC, and comes with a unique pressure-enhancing rubber seal. As the pressure increases, the design of the seal facilitates a distributed type of load on the seal; thereby, alleviating the load on the body of the coupling.

Environmental Sustainability of PVC Pipe

Environmental Sustainability of PVC Pipe Resource Efficiency - PVC saves fossil fuels. Its principal raw material is chlorine derived from common salt which is not a threatened resource.

Energy Efficiency - PVC pipe production consumes less primary energy in the manufacturing process when compared to steel, clay or ductile iron.

Highly Recyclable
Waste generated during pipe extrusion is pulverized and reprocessed and can be repeatedly extruded.

Lifeline for potable water - Potable water reticulation systems and effective wastewater handling systems are vital for the sustainable supply of clean drinking water. It is here that PVC as pipe material provides superior fit for purpose performance. PVC pipes minimize water losses by reducing line breakages. PVC water and sewer pipes are designed to perform without leakages. PVC pipe have a proven service life of up to 100 years. These characteristics save water and reduce cost of maintenance.

Water quality - PVC pipe delivers water as clean and pure as it is found at source. It imparts no taste or odor to the water it transports. It is not a source for the lead associated with metal pipe. PVC does not react with even the most aggressive water. The smooth interior surface is not bio-degradable and is resistant to biofilm build-up, a potential source of water disease such as E.coli.

Water tight joints - Water tight joints prevent the loss of valuable drinking water. PVC sewer pipe reduces leaks and reduce the chances of groundwater contamination. The water tight joints also reduce infiltration of groundwater and thus reduce the volume of water requiring treatment. Lower volume of water requiring treatment reduces operating cost of water treatment plants. Water tight joints also prevent the likelihood that embedment soil will be washed away. Gasketed push together PVC pipe systems are easy to install and can be placed in service quickly.

Corrosion resistance - PVC pipe is not vulnerable to external underground erosion or internal pipe corrosion. This eliminates the need to seek protection methods for corrosion. With PVC long-term durability is not compromised when encasement bags are damaged. PVC pipe is resistant to virtually all chemicals found in domestic and industrial waste water. PVC pipe is highly resistant to erosion or abrasion wear. Because PVC does not corrode it has among the lowest pipe break rates per km, saving precious water resources.

Strength - PVC systems can be designed to handle external loads as high as 75000 kg/m3 .This load represents up to 40 meters of ground cover. PVC pipes are able to handle ground movements by unstable and shifting soils.

Superior flow - PVC is corrosion resistant and this eliminates build-up of corrosion products that reduce hydraulic capacity. The smooth wall minimizes friction and flow resistance. The need for cleaning and maintenance is reduced and operating cost is thus reduced.

Superior strength-to-weight ratio - A lower mass of material is required to manufacture a meter of PVC pipe versus a meter of metal or concrete pipe. This weight advantage is significant. It makes PVC economically competitive on a length by length basis. It conserves resources, lowers transport cost, simplifies and reduces time required for installation. PVC reduces risk of injury to installation crews. Altogether PVC pipes reduce installation costs.

Toughness - PVC pipes can bend or flex when subjected to excessive loads. PVC pipes develop fewer cracks and breaks, thus minimizing leaks and operating costs. Water that leaks into waste water systems through cracks can increase the amount of water that requires treatment. This can drive up operating cost significantly.
