Drip Ring

Drip Rings, or Flushing Rings, are used in the oil or gas line. They are coupled between two seals.

The Drip Ring is circular, as a ring, with one or two holes. They may have one or two branches, based the usage that is made for. In the branch hole different type of instruments can be inserted:  pressure gauge, thermowell or it can be free to allow the drainage of condensate.

In correspondence to each hole the Drip Ring can be welded to a Weldoflange or a branch connector. 

La Meccanica Padana manufactures Drip Ring from 1/2" to 24" in different types of materials as follow:

• Carbon steel (ASTM 105, A516 Gr. 60/65/70, A350 LF2, A694 F60-65)
• Stainless steel (AISI 304, 316, 321, 347)
• Alloy steel (AISI Gr.1, Gr.5, Gr.9, Gr.91, Gr.11, Gr.22)
• Nickel alloys
• Duplex/Super duplex (F51, F53, F55, F44)
• Incoloy (800, 800H, 800 HT, 825), Alloy 20
• Hastelloy (C22, C276)
• Cupronickel Cu-Ni
• Monel 400
• Inconel (600, 625)
• Titanium (Gr. 1, 2, 3)

Drip rings have usually 1/2 inch socket weld or 3/4 inch tapped for connecting with valves and instruments. The face of the ring can also be made to matched with any flange type, and has different sizes based on the ASME flange rating of the process piping. The standard sizes for a drip ring are from 1 inch to 24 inch and ASME Pressure Classes 150 through 1500.  They can be manufactured according standard TB.DRI.5011 or special customer's requirements.
