Certa-Lok Yelomine
Low Pressure Fluid
Transmission Lines

CertainTeed Yelomine featuring the Certa-Lok Restrained Joint Pipe System and manufactured from a specially formulated PVC compound that contains impact modifiers and UV (Ultraviolet) inhibitors is uniquely designed for the rigorous application environment of the mining industry. These modifiers and inhibitors provide high impact strength over an extended period of time and allow Yelomine to be used in above-ground, exposed applications as well as underground or buried applications.

Yelomine pipe and fittings for low pressure fluid transmission lines are available in 2" (50mm) through 16" (400mm) diameters in 100psi (SDR 41-7 bar) to 250psi (SDR 17-18 bar) pressure classes. It is manufactured with IPS outside diameters in 20 foot (6m) laying lengths.

Yelomine pipe, couplings and fittings provide a restrained joint by utilizing precision-machined grooves on the pipe and in the coupling which, when aligned, allow a spline to be inserted, resulting in a fully circumferential restrained joint that locks the pipe and coupling together. A flexible elastomeric seal (O-ring) in the coupling provides a hydraulic pressure seal.

Note: If needed, the joint can be disassembled and re-used to allow for system changes, extension or removal for re-use. CertainTeed Yelomine joints can be easily disassembled, allowing for system changes, extension, movement or reuse of the entire system.

Non-Corrosive/Chemically Resistant

Yelomine is an excellent product for harsh environments. The inherent properties of PVC provide a product that is a non-conductor, which will not rust or corrode. Yelomine does not require cathodic protection, coating, wraps or other corrosion protection. PVC is extremely resistant to acids and most chemicals, and is unaffected by "hot" (aggresive) soils. Yelomine has an outstanding resistance to scale and scale build-up and (if necessary) can be cleaned by "pigging" the line.

Note: Special splines and O-rings may be required in either extremely acidic applications or hydrocarbon environments.
