Pipe swivel joints are manufactured for a broad range of uses in the chemical, petroleum, refining, mining, petrochemical, distilling, brewing, paint and ink industries, as well as farm irrigation and fertilizing. Design, plant and maintenance engineers use pipe swivel joints in flexible piping systems, loading arms, hose reels, sewer rodding and wastewater treatment equipment, and various types of process machinery. They also use swivel joints in drum filling applications, machine coolant transfer, and in a variety of in-plant fluid and dry bulk transfer applications.
Versatility is the key to these swivel joints. They make it possible to use rigid metal piping for loading and unloading fluids and dry product under pressure or vacuum without the difficulty or danger of handling heavy, cumbersome hoses.
General purpose swivel joints are available in a variety of materials, sizes and styles to meet any application. Sizes range from ¾” to 12”. Standard materials are aluminum, bronze, carbon steel, ductile iron and 316 stainless steel. Standard seals used are Buna-N, Fluorocarbon, PTFE, EPDM, Neoprene and Kalrez. End connections are FNPT, 150/300 ANSI Flanged Ends and Butt/Socket Welds.
Lubrication plays an important role in the life expectancy of a swivel joint. A high performance synthetic lubricant is recommended as it’s specially formulated to reduce friction and wear. Joints require only annual lubrication and will not drip, melt or carbonize. Temperature Range -40F – 750F (-40C – 399C).
