General Information Compare the ease of the Full Circle method to split mechanical sleeves or replacing a section of pipe and you will be convinced Full Circle is the best method! Smith-Blair Full Circle Repair Clamps are flexible. Each clamp consists of one or more stainless steel bands with cast lugs securely attached to the bands. The lugs accommodate the bolts and nuts when mounting the clamp on the pipe. Each clamp has a full encirclement, tapered, overlapping, gridded gasket with a flush mounted, bonded-in, stainless steel bridge plate that spans the band opening between the lugs and provides a full circumferential seal on the pipe. A Full Circle Repair Clamp is fast and simple to install and requires no special tools. The clamp is wrapped around the pipe, properly positioned over the area to be repaired or connected, and the bolts are then tightened. This installation compacts the rubber gasket tightly against the full circumference of the pipe wall forming a leak resistant seal. Product Features Lower material and labor costs - Each size fits a range of pipe types within its range, and can be used for repair, joining or tapping. Less crew, equipment, excavation and scheduling complications once the damaged pipe is exposed; one man with a single wrench can easily make the repair. No need for extra pipe fittings; Flexible Full Circle Repair Clamps are able to conform to pipe irregularities and provide an efficient leak resistant seal. No need for complete line shutdown and possible contamination - Full Circle Repair Clamps can be installed quickly and easily. Tightening the centermost bolts will usually stop flow of gas and then the other bolts can be equally tightened. No special tools or skills required for installation. The use of these clamps on PE pipe is not recommended! Smith-Blair, Inc. Full Circle Repair Clamps solve these piping problems: **Holes ***Cracks or splits ****Pin Holes Pulled service connections or branch lines **Holes should not exceed 1/3 the clamp width. When a section of pipe wall equal to 40-percent or more of the pipe’s circumference is broken away, a section of sheet metal should be placed over the opening to provide a sealing surface for the gasket. ***Cracks and splits require a small hole be drilled at each end to prevent spreading . 1 inch of clamp width on both sides of the damaged area is required. ****Pin holes require 1 inch of clamp width on both sides of the damaged area. Failures in gas piping both above and below ground present the operating gas utility with the problem of making repairs as rapidly as possible to remove the hazard. The use of Full Circle Clamps permits utilities to perform fast and efficient repairs. Leaks in cast iron, steel, or PVC pipe caused by corrosion, circumferential and longitudinal splits, porous weld, or punctures may be repaired economically with Full Circle Clamps using only hand tools. Warning: Full Circle Repaired Clamps do not restrain axial pipe movement. Use of axial restraint device will be required. 2 Both single and double band clamps are available. The selection of type is dependent upon which class of pipe is used by the utility. If the distribution system is primarily steel or cast iron, the single band clamp will meet most applications. Where both types of pipe are used, the double band clamp, which covers a wider O.D. range, is better suited. This clamp fits both kinds of pipe, thereby reducing the inventory required for emergencies. Note: Smith-Blair Full Circle Clamps comply with D.O.T. 192.717. When making repairs, the user should refer to D.O.T. 192 for recommended procedures. For Gas Service

Smith-Blair Repair Clamps seal positively and effectively Tapered and Lapped Gaskets Finely Grided Gasket Smith-Blair tapered, lapped gaskets provide a continuous and uniform seal over the full O.D. range of the clamp. Smith-Blair finely grided gaskets have 16 grids to the square inch; form a series of dams to conform to irregularities on the pipe surface; and seal effectively against rough or pitted surfaces to prevent development of a leak path. Smith-Blair Recessed Bridge Plate Uniform Distribution of Gasket Pressure Bonded-In Recessed Bridge Plate GASKET PIPE Smith-Blair bridge plates are precision set, flush mounted and securely bonded into the gasket during the molding operation. This provides a smooth surface, which insures a 100% encirclement of uniform gasket pressure. A dependable method of sealing. There is a uniform distribution of gasket pressure over the entire circumfrencee of the pipe. Other Methods of Bridge Plate Bridge Plate Glued on Top of Gasket Bridge Plate Glued in Molded Recess GASKET GASKET BAND A PIPE B A Bridge plates attached to the clamp band or glued to the outside of the gasket have exposed metal edges that hold the band away from the gasket, setting up low pressure points as in “A” and “B” above, which are potential leak paths. The exposed metal edge can also hang up on the clamp band and impede tightening of the clamp. PIPE B Bridge plates that are glued into recesses formed in the gasket during molding, may not fit the recess properly. There may be void spaces that create low pressure points, as at “A” and “B” above which are potential leak points. For Gas Service 5
225 Full Circle Repair Clamp Single Band Smith-Blair 225 Single Band Full Circle Repair Clamps provide a fast, economical means of repairing breaks, holes, cracks or other type of damage. The clamps are made for cast iron, steel and other types of pipe and have a built-in O.D. range enabling each clamp to fit several pipe outside diameters within a nominal pipe size range. Full Circle Repair Clamps feature a lap type gasket with molded tapered ends to provide efficient equalized sealing at the lap joint on any pipe within the clamp’s range. The gasket has a finely grided surface with the resilience to easily conform to irregularities on rough pipe surface or in pitted areas, providing an effective seal all around the pipe. A stainless steel bridge plate spans the opening of the lugs and is bonded flush into the gasket to prevent wrinkling in the lug area, providing an even gasket pressure at all points around the full circumference of the pipe. The band is made of stainless steel, selected to meet the necessary corrosion resistance, flexibility and strength requirements. Lugs are securely attached to the stainless steel band and have mutually supporting stabilizing fingers to permit maximum torquing of the bolts. The lug design includes a drop-in bolt feature that eliminates loose parts, saves time, and aids installation under adverse conditions. The bolts and nuts are low alloy steel with rolled threads, double radius heads and a generous shoulder to prevent bolt rotation under maximum torque loading. Standard 6 Nom. Size Inches O.D.

Full Circle Repair Clamps feature a lap type gasket with molded tapered ends to provide efficient equalized sealing at the lap joint on any pipe within the clamp’s range. The gasket has a finely grided surface with the resilience to easily conform to irregularities on rough pipe surfaces or in pitted areas, providing an effective seal all around the pipe. A stainless steel bridge plate spans the opening of the lugs and is bonded flush into the gasket to prevent wrinkling in the lug area, providing even gasket pressure at all points around the full circumference of the pipe. The band is made of stainless steel, selected to meet the necessary corrosion resistance, flexibility and strength requirements. Lugs are securely attached to the stainless steel band, and have mutually supporting stabilizing fingers to permit maximum torquing of the bolts. The lug design includes a drop-in bolt feature that eliminates loose parts, saves time and aids installation under adverse conditions. The bolts and nuts are low alloy steel with rolled threads, double radius heads and a generous shoulder to prevent bolt rotation under maximum torque loading. 8 Material Specifications Band: Lugs: Gasket: Stainless Steel Type 304 Ductile Iron ASTM A536, 65-45-12.

The kit consists of 6 mil (min.) thick polyethylene sheeting and an extra nut. The nut is for the attachment of an anode or bonding wire, since the gasket electrically insulates the clamp from the pipe. The sheeting, when loosely wrapped around the clamp, protects it from the surrounding soil, biological activity and stray currents. Polyethylene encasement has been subject to a lot of research and is recognized as an effective method of mitigating corrosion in underground piping systems.
