Jacketed Swivel Joints


Any of OPW Engineered Systems fabricated steel or stainless steel swivels can be ordered jacketed. Jacketed swivels are commonly used in applications where relatively high temperatures must be maintained, such as asphalt, sulfur, waxes, and resins.

OPW jacketed swivels feature full steel jackets on the elbow portions only. Conductive heat from the jacketed elbows of the swivel joint provides sufficient heat to the seal area, which is generally field-insulated. For applications considered highly critical, the seal area of the joint can also be jacketed. Standard steam connections are 3/4" FNPT.

Mediums other than steam can also be re-circulated through OPW jacketed swivels to heat or cool products, such as oil, water, and glycol, among others.
