The installation of ductile iron flanged tees is different from other pipe fittings due to several reasons:
Handling and Transportation:
Heavier and bulkier than light plastic or copper fittings, ductile iron flanged tees necessitate more caution and specialized equipment during handling and transportation. Appropriate lifting methods must be employed to prevent damage to the tee or injuries.
Alignment and Positioning:
These tees require precise alignment with the connecting pipes or fittings to secure a leak-proof seal at the flanged connections. The tee’s weight and rigidity can make minor adjustments challenging, hence the importance of correct usage of gaskets, flange bolts, and torque specifications.
Supports and Bracing:
The weight and size of ductile iron flanged tees usually call for robust supports and bracing to prevent sagging or strain on the pipe system. This might entail the use of concrete pads, wall brackets, or other specially designed support structures.
Joining methods:
Ductile iron flanged tees are generally joined to components using bolted flange connections instead of threaded or push-fit connections typical of other pipe fittings. This requires appropriate selection and installation of gaskets, flange bolts, and torque patterns to form a leak-proof seal.
Excavation and Backfilling:
For an underground setting or buried application, the excavation and backfilling process must be meticulously managed to prevent damage to the tee and surrounding pipes. Adequate bedding, shoring, and compaction techniques are crucial to ensuring the installation’s long-term stability and performance.
Testing and Inspection:
These tees, often crucial in many pipe systems, require extensive testing and inspection throughout and post-installation, ensuring proper function and compliance with applicable codes and standards.
Correct installation of ductile iron flanged tees relies on proper training, specialized tools, and adherence to manufacturer’s instructions. Consulting with experienced plumbers, pipefitters, or engineers can help secure an installation that aligns with all requirements and best practices.
