LOCKING WASHER PLATE: Locks into position for easy tightening of nuts. 

LUGS: MIG-welded to receiver bar and fully passivated after welding. Leading edge is rounded to prevent them from catching bolt bars during installation. 

SHELL: 2B finish. 

BOLTS: Thread-rolled for strength and Teflon* coated to prevent galling. CASCADE bolts are MIG-welded to the receiver bar and fully passivated after welding. 

NUTS: Type 304 or 316 stainless steel.
RECEIVER BARS: TIG-welded to shell to form a strong 

fusion, and fully passivated after welding. 

GASKET: Natural rubber specially formulated for water service, and made to ASTM D 2240 has antioxidant/ antiozonant agents to increase shelf life. All gaskets have a gridded design, tapered ends and vulcanized armour plates for easy installation and optimum sealing efficiency. 

ARMOUR: Heavy gauge stainless steel vulcanized into the gasket at the time of moulding, to ensure: 

• that it fits permanently
• that it fits perfectly
• that it provides a smooth transition from rubber to metal

General Information 

1. Recommended pressure ratings:
(1) Clamps to suit pipes up to 300mm nominal size 1.6 Mpa (2) Clamps to suit pipes above 300mm - 450mm nominal
size 1.2 Mpa 

2. The amount of pressure that a full circle repair clamp will contain is proportionate to the diameter of the pipe being repaired and the amount of torque applied to the bolts.
Smaller diameter repair clamps will contain more pressure than larger diameter repair clamps.
Cleaning and lubricating bolt threads will reduce friction and permit greater torque. 

3. The pressure containing capability of a repair clamp is influenced by the pipe size, the type and extent of damage to the pipe, environment and service conditions and installation workmanship.
