DDH Series Reinforced Dip Pipes

Reinforced Dip Pipes

Part Number: As shown here, the PART NUMBER (DDH-NS-MF-L1) defines the series (first three characters), the nominal tube and connecting flange size NS, the mounting (or nozzle) flange size MF, and the insertion length L1. Use a decimal number to indicate NS. Then, replace MF with a decimal number to indicate the nominal size of the mounting flange and replace L1 with the insertion length in inches.
For example, a 1-1/2” Reducing-Flange Dip Pipe with a 6” mounting flange x 80” insertion length would be
DDH-1.5-6-80


Notes
  1. Standard flanges have ANSI Class 150 drilling. Class 300 and other sizes available.
  2. Standard tolerance on inserted length is ± 1/2”. Closer tolerances available, contact the factory.
  3. Standard distance (L2) between flange sealing faces is shown in the L2 Distance Table . To order non-standard spacing, contact the factory.
  4. Most dimensions are governed by connecting flange size as shown in the Standard Dimension Tables.
  5. Maximum standard overall length is 16 feet. For longer lengths, contact factory.
  6. For service conditions exceeding 350 F°, or 150 PSI, or vacuum service, contact factory.
