A quick reference of some types of sanitary connections found in the industry are illustrated below. There are also John Perry and Q-Line connections; see online catalog for additional information.

Clamp Connection Bevel Seat Connection
Clamp Connection Bevel Seat Connection
 
I-Line Connection Buttweld Connection
I-Line Connection Buttweld Connection

NOTE: Clamp type connections are the most popular and are sometimes referred to as Tri-Clamp connections.

All connections are Tube OD ½" to 12"

Materials are available in 304 and 316L stainless steel, (other alloys can be special order)

Tube Hanger

Tube Hanger Support Recommendations:
Processing lines are not to be rigidly anchored to equipment. They must be allowed to float. Temperatures can cause expansion and contraction - if tube hanger supports are mounted incorrectly, distortion and possibly leakage of the lines could occur.

Proper Tube Hanger Support Installation:
Straight sections of tube need support every 10 feet. Support needs to be on each side of every valve (as close as possible to the connection). Additionally, a support needs to be at each change of direction.

Notes:

  • * Dixon Sanitary does not offer at this time
  • MP in a part number usually means a clamp fitting
  • W in part number usually indicates a weld part
  • I in a part number usually indicates I-Line fitting
  • Bevel seat is tricky...consult literature and cross reference sheet
