Illustrated above: Based on 20' (6.1 M) carrier pipe segments in a casing of not more than 300' (91.5 m). Consult Corrosion Control Products Company for longer casings and for concrete pipe. Use 2 spacers/length of pipe for 13' (4.0  m) sewer pipe segments.

Installation

Component Parts - Installation

Separate segments are connected by inserting the buckles into slots on the adjacent segment.

A. Buckles with angled ratchet nubs.
B. Slots accept buckles and hold segment in position around pipe in preparation for final tightening.
C. Slot accepts Slide-Lock. Arrow molded on seg­ment indicates correct insertion direction.
D. Runners are available in a variety of heights to allow for desired carrier pipe placement in casing.
E. Slide-Lock is used to ten­sion the segments together after installation on pipe. Channels face up during insertion while the correct size slide-lock (micro, mini, midi, maxi) is molded on the flat (bot­tom) side.
F. Slide-Lock is inserted into channel to close and lock the segments together. Slide-Lock removal and re-insertion will ratchet the segments together for final tightening against carrier pipe.

Installation Tips

• As with any installation process, it is important to wear appropriate eye and personal protection. This is even more important if installation work must be done at low temperatures.
• It can be beneficial to place the Ranger II segments and Slide-Locks in a warm environment while awaiting installation in colder climates.
• During the installation process, no matter what the temperature, it is essential that the Slide-Locks be supported by the carrier pipe to eliminate the possi­bility of bending the Slide-Locks during insertion.
• Under hot installation conditions, it is better to allow the product to age a couple of hours at ambient temperature prior to assembly.

Illustrated Installation Procedure
   

Verify that Slide-Locks match segment size by checking to ensure the segment name (Mini) matches the name molded on the bottom of the Slide-Lock. Note: Micro & Mini segment both use the Mini Slide-Lock.

Ranger II - Mini for 2.48" to 5.51" (63 to 140 mm) Diameter Carrier Pipe
Band Width = 3.15" (80 mm)

Verify that Slide-Locks match segment size by checking to ensure the segment name (Mini) matches the name molded on the bottom of the Slide-Lock.

Ranger II - Midi for 5.51" to 16.65" (140 to 423 mm) Diameter Carrier Pipe
Band Width = 5.12" (130 mm)

Verify that Slide-Locks match segment size by checking to ensure the segment name (Midi) matches the name molded on the bottom of the Slide-Lock.

Ranger II - Medi for 16.77" to 25.98" (426 to 660 mm) Diameter Carrier Pipe
Band Width = 6.87" (174 mm)

Verify that Slide-Locks match segment size by checking to ensure the segment name (Maxi) matches the name molded on the bottom of the Slide-Lock. Medi & Maxi segments both use the Maxi Slide-Lock.

Ranger II - Maxi for 25.98" to 37.60" (660 to 955 mm) Diameter Carrier Pipe
Band Width = 8.86" (225 mm)

Verify that Slide-Locks match segment size by checking to ensure the segment name (Maxi) matches the name molded on the bottom of the Slide-Lock.

A. Casing Spacers

Upon completion of the installation of the steel pipe encasement, the contractor shall furnish and install a Ranger II boltless casing spacer on the carrier pipe as described below.

Casing spacers shall be spaced a maximum of eight (8) feet apart along the length of the carrier pipe with one casing spacer within two (2) feet of each side of a pipe joint and the rest evenly spaced. Wood skids are not an acceptable method of supporting the carrier pipe.

• Casing spacers shall be all non-metallic, molded in segments for field assembly without any special tools. Spacer segments shall be secured around carrier pipe by insertion of a cinching spine. The casing spacer polymer shall contain ultraviolet inhibitors and shall have a minimum compressive strength of 3,000 psi, an 800 Volts/mil dielectric strength and impact strength of 1.5 ft-Ibs./inch. Each casing spacer shall have full length, integrally molded skids extending beyond the bell or mechanical joint of the carrier pipe.
     
• Spacers shall be at least as wide as listed below.

• The casing spacers shall be the PSI Ranger II as manufactured by Pipeline Seal and Insulator, Inc., Houston, Texas.

B. End Seals

After insertion of the carrier pipe into the casing, the ends of the casing shall be closed by installing 1/8" thick synthetic rubber end seals equal to the PSI Model "C" end seal as manufactured by Pipeline Seal and Insulator, Inc.

ISO 9000 Registration

Each casing spacer and end seal shall be manufactured at a facility that has a Registered ISO 9002 Quality Management System. Copy of current ISO 9002 Registration shall be provided with material submittal.

All Ranger II's require more than one segment to complete a spacer. In addition, all Ranger II's are available with a number of different runner height options which are used to guarantee clearance of the mechanical joint, provide for options in carrier pipe positioning with­in the casing or to compensate for grade elevation adjustments. Following are examples on how to size Ranger II spacers for various applications.

Example 1 - Installation with Equal Length Runners - Maximum Allowable Height

20" Ductile Iron pipe (21.60" O.D. barrel & 28.63" O.D. bell) inside a 36" casing with a 0.375" wall thickness. 
A. Find carrier pipe O.D. (21.60") from adjacent chart and choose the proper size and number of segments. One spacer would require 5 - Maxi segments. 
B. Determine maximum runner height with equal length runners.

Divide this number (12.65") by 2 to obtain the total allowable runner height = 6.325" 

C. Choose a runner height of this value or less. Solution: 5 - Maxi segments with runner heights of 5.90". Ordering Codes: See Back Page for Ordering Code Sequence.

Note: This combination will also restrain the pipe from flotation within the casing pipe by allowing only about 1.8" of clearance between the top runners and the casing I.D.

Example 2 - Carrier Pipe Installed Just To Clear the Bell

Suggested minimum clearance is at least 1" (1 /2" on both sides) 20" Ductile Iron pipe (21.60" O.D. barrel & 28.63" O.D. bell) inside a 36" casing with a 0.375" wall thickness. 
A. Find carrier pipe O.D. from chart (21.60") and choose the proper size and number of segments. One spacer would require 5 - Maxi segments.
B. Determine runner height.

Divide this number (8.03") by 2 to obtain the minimum runner height to just clear the bell = 4.01" 
C. Choose a runner height between 4.01" and the maximum allowable runner height (6.32") determined in Example 1. Solution: 5 - Maxi segments with runner heights of 4.92". Ordering Codes: See Back Page for Ordering Code Sequence.

Example 3 - Carrier Pipe Centered in Casing (within approximately 1/2" of casing center)

20" Ductile Iron pipe (21.60" O.D. barrel & 28.63" O.D. bell) inside a 36" casing with a 0.375" wall thickness. 
A. Find carrier pipe O.D. from chart (21.60") and choose the proper size and number of segments. One spacer would require 5 - Maxi segments.
B. Determine runner height.

Choose a runner height closest to this value (6.82"). On the chart, a 6.88" runner would be closest; however 6.88" is larger than the maximum allowable runner height as determined in Example 1. In this case, use 6.88" runners on the bottom to center the carrier pipe approximately and adjust the top runner heights to allow insertion within the casing. Use the following procedure to determine max. height for top runners:

Select the closest runner height from the chart less than (5.77"). In this case a 4.92" runner height would be specified for the top runners. Also verify this is of sufficient height to clear the bell (4.01") which in this case it is. Solution: 2 - Maxi segments with runner heights of 6.88" and 3 Maxi segments with runner heights of 4.92". Ordering Codes: See Back Page for Ordering Code Sequence

Example 4 - Ranger II used to Adjust for Grade Elevation Changes 

Within a "segment size" various height runners may be used to adjust for grade elevations. In the above example a 20" DI pipe with a 21.60" O.D. will require 5 Maxi segments to make a complete casing spacer. One could use any combination of Maxi segments with runners between the Minimum Allowable Runner Height of 4.01" and the Maximum Allowable Runner Height of 6.32" to position the carrier pipe at a particular height. Any other combination of runner heights of Maxi segments that fall between these values may be used, although no more than half of the segments should consist of the higher runner height segments.
