Tri-Clamp Sanitary Spool (SPOOL4)

Clear
Quantity - +

Description

Sanitary stainless steel tube is fabricated to specific lengths with tri-clamp fitting ends.

When combined with other Tri-Clamp fittings, clamps, and gaskets, sanitary spools can build a process line without the need for on-site welding and fabrication, and installed saving time. Tri-Clamp spool pipes also have the added benefit of being non-permanent than their welded tubing cousins and can be easily disassembled, moved, or reassembled in a different configuration. The versatility and cost savings of a prefabricated spool pipe make them a popular solution for tubing needs.  Learn more about tri-clamp spool assemblies. Custom sizes available. Please call for pricing.

    A

    I believe we can do this.  I'll send you a quote.

  2. Are 10 ft spool assemblies available?
  3. Q Are 10 ft spool assemblies available?
    A Yes. We can fabricate Tri-Clamp Spool Assemblies up to 20'. However, due to the size, anything over 7' would need to ship via freight carrier. Please contact us for additional details.
  4. Hello, is it possible to use tri-clamp connections in vacuum application? If yes, what is a limitation regarding the temperature? Thanks!
  5. Q Hello, is it possible to use tri-clamp connections in vacuum application? If yes, what is a limit...... Read more
    A We do not offer tri-clamp vacuum fittings. However, please check out Ideal Vacuum for more information.
  6. Hello, Do you do custom spools? I need two spools. OD: 8" Length: 40"
  7. Q Hello, Do you do custom spools? I need two spools. OD: 8" Length: 40"
    A

    Yes, we custom fabricate all tri-clamp spool assemblies to order.  I will send you a quote.

  8. What are the ID tolerances for a 3/4" spool assembly? Is this a typical standard in the industry? I want to ensure I have min steps between old and new tubing from various manufactures.
  9. Q What are the ID tolerances for a 3/4" spool assembly? Is this a typical standard in the industry?...... Read more
    A All tolerances are +/- 0.005. Please let us know if you have any other questions.
  10. What would the RA finish be on the ID and OD? Is this hand-welded or machine welded? What weld spec is used when welding?
  11. Q What would the RA finish be on the ID and OD? Is this hand-welded or machine welded? What weld sp...... Read more
    A Our standard surface finish for these tri-clamp spool assemblies is 32Ra ID/OD. We can also offer 20Ra and 15Ra for an additional fee. Regarding welding specs, we weld to ASME Section IX and AWS 18.1. These are semi-automatically welded.
  12. Do you make or sell any TC fittings that have a dip tube attached? Specifically I am interested in a 1.5” Tri-Clamp. We are using this fitting to connect to a bulkhead for a liquid input and would like to direct the liquid stream straight down into the vessel with the dip tube, to ensure the liquid does not drip down the side of the vessel. We will be connecting the dip tube to a 1.5” Tri-Clamp on the bulkhead and a 1.5” Tri-Clamp to barb adapter (both from Sanitary Fittings).
  13. Q Do you make or sell any TC fittings that have a dip tube attached? Specifically I am interested i...... Read more
    A We have made what has been referred to as "dip tubes" in the past. I can send you copies of previous customer drawings for dip tubes for your reference. We are able to equip the ends with a variety of fitting connections including tri-clamp elbows, NPT Threads or hose barbs. Please contact us for more information.
  14. what is the pressure rating of a spool
  15. Q what is the pressure rating of a spool
    A

    All of our tri-clamp fittings have pressure ratings that are dictated by the type of clamp used in the process line. The pressure rating is also affected by the temperature of the media that you are processing. For exact pressure ratings, please consult any of our Tri-Clamp Clamps for the size that you are working with and it's corresponding pressure rating.

  16. What is the minimum length of these spool assemblies.
  17. Q What is the minimum length of these spool assemblies.
    A We can manufacture these tri-clamp spool assemblies to an overall length of 1.5" or greater.
