Flexible hose is engineered specifically for use as inlet and outlet connections to unions. It is used to prevent pipe strains from creating stress on the rotating union and limiting the rotating union's built-in flexibility.
Sight flow indicators are engineered to provide visual observation of liquid and non-hazardous gas flows. These pipeline indicators are available with ductile iron bodies in sizes 3/8" to 4" with threaded or flanged connections. All glass windows are made of borosilicate glass. Sight flow indicators can be furnished with special transparent-type Mica liners to protect the glass against erosion.
Syphon elbows are used with rotary steam unions to remove condensate from the roll. Conventional elbows use gravity to secure the elbow in place. Spring-lock and "pinless" locking elbows are also available for increased reliability at higher speeds. Conventional elbows are made of ductile iron while locking elbows use stainless steel and other corrosion-resistant materials.
