Questions & Answers 4

Questions and answers of the customers

  1. Q If I want to weld one end to a one inch tube, should I purchase a 1" size or something smaller?
    A All sizes are measured by the Outside Diameter (OD) of the fittings. So a reducer of size 2" x 1" will have ODs of 2" on one end and 1" on the other.
  2. Q 32Ra. Is this for both the id and od or just one or the other, and if it is either, which side gets polished???
    A Our standard fittings are 32Ra ID/OD. Both are polished. Our BPE Fittings available would have 20 or 15Ra ID with a 32Ra OD standard.
  3. Q ARE THESE REDUCERS MACHINED OR ARE THEY ROLLED AND WELDED TOGETHER
    A Reducers can be made in a variety of ways: Rolled, machined or pressed. In order to determine the manufacturing method, you would need to compare the parts with their associated Material Test Report (MTRs). The same reducer could be made differently depending on who is making it.
  4. Q I need an 8 -- 2" sanitary reducer but I don't see it here. Can you guys custom fabricate this part?
    A Yes, Sanitary Fittings does offer custom fabrication depending upon your needs. In this case we have a couple of options. Either you can buy an 8 -- 4 and 4 -- 2 reducer whereby you can weld together or we can create this part for you by doing the same thing. The overall length of this new reducer will be around 14 - 15" inches long. You can save time and money by welding this together yourself but it's up to you and your comfort level. Please call us if you have additional questions on custom fabrication and pricing. Thanks!
