Q: What types of pipes can TPATM be used to inspect?
A: TPATM can inspect the following types of watermains provided they are full of fluid and pressurized to at least 5 psig / 35 kPa / 0.35 bar:
|
Cast Iron (CI)
|
up to DN 600
|
|
Stainless Steel
|
up to DN 450, leak detection up to DN 600
|
|
Spun Iron (SI)
|
up to DN 600
|
|
Ductile Iron (DI)
|
up to DN 600
|
|
Asbestos Cement (AC)
|
up to DN 450, leak detection up to DN 600
|
|
Acrylonitrile butadiene styrene (ABS)
|
up to DN 280
|
|
Polyethylene (PE)
|
up to DN 280/315 depending on SDR
|
|
Polyvinyl chloride (PVC)
|
up to DN 280/315 depending on SDR
|
|
Prestressed concrete cylinder pipe (PCCP)
|
Leak Detection Only
|
Larger diameter conduits can be inspected using with the TPA+ system which makes use of an in-pipe sound source and hydrophones. TPATM can also be used to inspect sewage force-mains, insulated steam, hot water and chilled water pipes of comparable diameter.
