Specifications: 

Band: Type 304 stainless steel Studs and Heavy Type 304 stainless steel per ASTM A193 and A194 Coated nut threads to prevent galling Studs are
Hex Nuts: permanently attached to the clamp sidebar by means of a Metal Inert Gas (MIG) weld
Lugs: Type 304 heavy gauge stainless steel, MIG welded to clamp sidebar Lugs are rounded and tapered for easy installation
Sidebars: Type 304 heavy gauge stainless steel Tungsten Inert Gas (TIG) welded to form a strong, permanent fusion with the repair clamp band
Lifter Bar: Type 304 heavy gauge stainless steel Lip curve holds bolts in position while tightening and serves as a bearing surface for stainless steel nuts and washers
Gasket: Gridded virgin Styrene Butadiene Rubber (SBR) compounded for water service per ASTM D2000 Gasket ends are tapered for a dependable seal SBR is suitable for temperatures of 150°F continuous, 180°F intermittent
Armor: 1/4 hard heavy gauge stainless steel vulcanized and recessed into the gasket to ensure uniform compression against the pipe
Passivated: All clamps are fully passivated by means of a chemical technique which restores the corrosion resistant characteristics of the stainless steel
Options • Conductivity strips
Include: • NBR (Buna-N) gasket (suitable for natural gas applications) Recommended for 220°F continuous and/or 240°F intermittent
• EPDM gasket recommended for 300°F continuous and/or 320°F intermittent
• 316 stainless steel
• 1″ offset gasket for overlapping clamps for extended lengths 

Belleville Belleville washers use on HDPE: Belleville washers, also referred to as spring washers, promote consistant force on the gasket as the pipe Washers for diameter expands and contracts The Belleville washers are made of 17-7 PH stainless steel Depending on the pipe size and recommended installation torque, Belleville washers are used singularly, or in a stack to allow for more expansion/contraction of the pipe Flat washers not always included or needed on some HDPE products.

Typical Problems Solved With our repair clamps :

• Cracks or full breaks in asbestos-cement and iron pipe
• Pinholes in pitted iron and steel pipe.
• Holes in asbestos-cement, iron, steel and plastic pipe.
• Splits in asbestos-cement, iron, steel and plastic pipe.
• Pipe ends of the same diameter with slight separation.
• Repair leaking tap with a tapped repair clamp.
• Broken asbestos-cement pipe coupling.
• Fish mouthed gasket in asbestos-cement pipe coupling.
• Remove coupling and replace it with a clamp.

Conditions of Test : 

• Test Pipe: asbestos-cement, cast iron or steel
• Two pieces of test pipe with average space of 1/8″ between ends, coupled together with 7-1/2″ wide clamp
• 5/8″ bolts (clamps up through 4 73″ O D ) tightened to a torque of 30-35 ft lbs , 5/8″ bolts (clamps over 4 73″
O D ) to 70-80 ft lbs
• As supported in AWWA C230, repair clamp service performance is installation and application sensitive.
Each installation may involve a particular set of conditions that could provide or prevent suitable results
