412 Fabricated Steel Tapping Sleeves
Built-in benefits make these heavy fabricated steel sleeves increasingly popular for making larger taps on all types of pipe. By placing the design emphasis on eliminating problems inherent with older pipe and field installations, 412 Tapping Sleeves have taken the complexity out of tapping larger pipe. |
|
| Built in range assures proper fit on more than one class of pipe - reducing inventory requirements and Alignment recess for aligning sleeve and tapping valve. Corrosion resistant, high strength low alloy bolts and the chance of not having the right size sleeve. |
| Ease of assembly eliminates extra equipment, time and specially trained personnel. |
| Ready availability means taps can be made without long delays - even taps on special sizes of pipe or services requiring high pressure flanges. |
| Direct reinforcement of the pipe by the sleeveeliminates flexing or deflection of pipe opposite the tap. Less weight than heavy cast iron sleeves reduces the load on the pipe. |
Most important, 412 Tapping Sleeves assure a safe dependable tap. A large gasket cross section provides a positive initial seal which increases with increases in line pressure. in retaining cavity.forces pipe - eliminates deflection possibility. |

412 Tapping Sleeve Installation Instructions
- * Thoroughly clean pipe surface. Check the size and range of the tapping sleeve to verify correct size product.
- * Check surface where gasket will seat to make certain pipe is free of flaws, gouges and extreme irregularities.
- * Lubricate pipe and face of gasket with soap-water or gasket lubricating solution. Do not use grease or pipe lubricant.
- * Position outlet half of body on pipe, making sure outlet is aligned with branch line to be connected. Never position so that rotation is required.
- * Position back half of body and install bolts.
- * Tighten outside bolts first, working toward the center.
- * Tighten bolts evenly. Alternate from one side of sleeve to the other. Tighten bolts to the following toque levels:
Pipe sizes 6” - 12” -100 ft. lbs. of torque Pipe sizes 14” & larger -125 ft. lbs. of torque
NOTE: For test and working pressure above 250 PSI bolts must be tightened to 150 - 170 ft. lbs. of torque. (Contact for proper application.)
On Thin Wall, PVC (SDR21, 26), and Flexible Pipe 50 - 55 ft. lbs. minimum HDPE SDR11, SDR17 -6” - 12” 60 ft. lbs. minimum HDPE SDR11, SDR17 -14” and Larger 90 ft. lbs. minimum
- * Check inside of sleeve neck to make certain gasket is properly seated and not protruding where tapping cutter may damage it.
- * Install tapping valve. recommends adherence to the AWWA M-44 Manual for proper valve installation, support and trenching.
- * Test assembly seals using test plug provided on sleeve or test connection on tapping machine. Note: No more than 10% above line pressure on HDPE or maximum pipe working pressure rating. When assured that all seals are tight and test is completed, re-check bolt torques after 15 minutes and proceed with tapping operation.
Note: Size on size tapping cutter must not be larger than recommended by pipe manufacturer. Also, tapping operation must not force the pipe away from the gasket seal.
