Joints are crucial elements of drainage systems

Internal pressure resistance

Couplings are the link between the different parts of the system and ensure that the whole system is watertight. As the robust cast iron components can address any pressure hazard, then the couplings will be submitted to the strain.

 

Quality standards 

All Saint-Gobain PAM couplings are compliant with standard EN877.

Choosing a complete and consistent range of cast iron products, whose assembly has been performance tested against regulatory requirements, provides you with peace of mind that few other materials can guarantee.

Standard Pressure couplings

Generally, the pressures that occur in wastewater drainage systems cannot exceed the pressure corresponding to the height of one storey, i.e. about 0.3 bar, as sanitary appliances on each floor serve as outlets in case of accidental overloading. The couplings we describe as “standard pressure” are perfectly suitable for this common type of application.

SMU PAM coupling

SMU PAM is inspired by the PAM Rapid coupling design, it is available in small diameters and has the same performance but is a larger version. This larger coupling facilitates installation where cuts are not perfectly square.

PAM Rapid coupling

The single-bolt PAM Rapid coupling allows fast and reliable installation. It ensures optimized water tightness, pressure and corrosion resistance.

PAM R coupling

PAM R, “R” for Repair, this coupling is particularly suited to repairs and retrofits. It is installed in two separate parts.

NEW: HIGH PRESSURE COUPLINGS

RESISTANCE TO HIGH PRESSURE WITH PAM HP FLEX & GRIP:

In some rare cases and mostly for rainwater networks, there could be a risk of accidental overloading. The pressure resistance required to ensure these systems remain leaktight and stable depends on the height of the water column liable to occur, and calls for high-pressure couplings able to withstand the resulting pressure (up to 10 bar).

PAM HP FLEX couplings can withstand up to 10 bar hydrostatic pressure. They are the solution for all projects where high pressure loads can occur, mainly in high-rise buildings but also in infrastructure.  

 

RESISTANCE TO END THRUST EFFORTS WITH PAM HP GRIP:

Some specific points on a pipe system may be subjected to thrust loads due to changes of direction and gradient, branches and plugs. To address the thrust forces, PAM HP GRIP coupling can be used.

PAM HP GRIP, are self-anchored with built-in-claw rings to withstand high pressure and address end-thrust efforts.  They are a good alternative to standard joints and gripped collars to save installation time and space where room is scarce.
