Series 908 ID Controlled MJ Adapter Submittal
MJ Adaptor Transitions
The Poly-Cam ID Controlled MJ Adaptor Transition is a double restraint multi-level mechanical transition fitting. This design allows a non-reduction, smooth bore transition between the HDPE and Ductile pipe. The polyethylene or pipe-quality copolymer material are hydraulically compressed into the transition fitting. The HDPE and MJ Adaptor is joined with a compression ring that restrains the HDPE onto the MJ Adaptor.
Design
Relaxation of the pipe creates a seal to prevent leakage.
A MEGALUG®, FIELD LOK®, or TUFGRIP® (Tyler Union) restraint is required to be used with this product. Standard glands will not completely restrain the expansion/contraction of the HDPE. This design allows installer to use standard length bolts instead of the more costly longer bolts. The double-restraint design also eliminates the need for wait-time in order to backfill.
- Sizes range from 3” to 24” in both iron and ductile pipe
System Performance
The transition fitting is designed to handle the pressure rating of the HDPE pipe with a 2:1 safety factor at 73.40 degrees Fahrenheit with a minimum 50-year design life.
Quality Assurance
The transition fitting shall be manufactured by Poly-Cam, Inc. Poly-Cam, Inc. shall provide quality assurance with regards to proper installation, compatibility, performance, and acceptance. The transition joint meets or exceeds the requirements of:
- ASTM 1598 and ASTM 1599
- Meets ANSI/AWWA standard C-906
Installation
HDPE pipe end: Install transition fitting to comply with the pipe manufacturer’s recommended procedures. All field welds shall be completed per Plastic Pipe Institute’s welding procedure for butt fusion.
Ductile Fitting: The entrance of the coupling is tapered at the beginning. The polyethylene or copolymer material is cold pressed onto the coupling. This allows the material to relax into the multi-level barb system.
Material
Ductile Fitting:
- Manufactured of American-made cast ductile iron.
- The compression rings are manufactured out 304 stainless steel tubing (ASTM A249 or ASTM A269) and or ERW pipe (ASTM SA-312).
High-Density Polyethylene: HDPE pipe
- Meets ASTM D-3350 with minimum cell classification values of 345464C (PE 3408), PE445574C (PE 4710)
- Meets ASTM F714.
- Density shall be no less than 0.955 g/cm as referenced in ASTM D1505
- Melt index no greater than 0.15 g/10 minutes when tested per ASTM D 1238
- Tensile Strength at Yield –tensile shall be 3,200 psi to less than 3,500 psi as referenced in ASTM D638
- ESCR-Environmental Stress Crack Resistance shall be over 5,000 hours with zero failures when tested per ASTM D 1693-Condition C
- All pipe meets ASTM 3035.
- All certifications will be submitted upon request.
Warranty
The warranty period is one year after the date of substantial completion of installation.
