Smith-Blair - Model 234 -Single Band Tapped Full Circle Repair Clamp

The stainless steel outlet is welded to the band and is available with NPT, threads. O.D. ranges are designed to fit cast iron, steel and most other types of pipe. The clamps have a built-in O.D. range enabling each clamp to fit several pipe outside diameters.

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 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 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.

• Full circumference single or multiple section stainless steel bands are available in 7 1/2”, 10”, 15”, 20” and 30” widths to fit virtually all types and sizes of pipe up to 12” in diameter
• All weldments including studs, sidebars and fingers are constructed of premium grade stainless steel to minimize the possibility of corrosion
• Smith-Blair’s exclusive “C” shaped keeper bar permits fast run-down of nuts against the clamps weldments while equalizing tension along the full length of the clamp
• Bridge plate flush mounted and bonded to the gasket assures even distribution of gasket pressure and prevents crimping
• Gridded, tapered, overlapping gasket design offers excellent full curcumferential sealing and full adjustment to rough pipe surfaces
• A special high-strength ductile iron alloy lug utilizes a strength efficient computer-aided design that’s not only stronger, but also lighter and easier to install. Lugs are Flexi-Coat epoxy coated
• Drop-in, self-securing bolts eliminate loose parts, save time and make installation possible with only one wrench
• Lugs with mutually supporting sliding fingers to assure proper bolt alignment while tightening. Permits maximum torque without bending of bolts
• The band locking system uses a unique lug core design and a band hemming process that resists pull-out and provides maximum band retention
