In underground applications, ductile iron pipe features the "push-on" joint, an extremely capable gasketed joint
that is very easy to install.
The PVC pipe uses a gasketed joint
; HDPE pipe uses a heat-fused joint.
Further claims are that the easily installed PVC integral bell gasketed joint
, when installed properly, will easily meet a 50 gallons/inch diameter/mile/day infiltration/exfiltration parameter and other performance standards such as specific situations based on low pressure air testing.
Introduced in 1995, the product adds strength and structural stability to the gasketed joint
, Armstrong said.
PVC accommodates expansion and contraction every 20 feet at the gasketed joint
diameter), structural integrity, and ease of joining with a bell and spigot gasketed joint
The most common and successful technique employs a gasketed joint
. The gasketed joint
may be either integral bell design (formed as a continuous, homogeneous entity with the pipe) or may consist of a separate sleeve-type coupling.
