Additionally, it has a water-tight bell-and-spigot joint
and, like all of JM Eagle's polyethylene pipe products, it provides unmatched resistance to corrosion, abrasion and UV degradation.
EDITOR'S NOTE: Because Uni-Bell focuses solely on the gasketed, bell-and-spigot joint PVC pipe, the association did not provide information about restrained-joint PVC pipe, in common use today for horizontal directional drilling and pipebursting installations.
The other significant attribute is its deep-insertion, gasketed bell-and-spigot joints, which have not had the infiltration and exfiltration problems of other materials.
In addition, the silky nature of a chlorinated robber surface was such that a treated pipe ring would no longer grip and roll in a bell-and-spigot joint.
Another was from a region where it is understood that pipe tings in bell-and-spigot joints were not in common use at the crucial time; external pipe bands had been popular.
Note: information from Uni Hell covers only gasketed, bell-and-spigot joints
plants -- two in Southern California -- produces the 12" to 36" annular corrugated smooth interior high density polyethylene pipe with bell-and-spigot joints
