Dip Pipes

Lined and Jacketed with PTFE for Loading, Unloading & Decanting

Resistoflex Dip Pipes are designed to provide the ultimate in corrosion-resistant, non-contaminating construction to 350°F for loading vessels below the liquid level, and decanting and unloading without the need for bottom outlets. The maximum recommended operating pressure is 150 psi.

They are designed to withstand high mechanical loads imposed by mixing or agitation in process vessels and reactors. The schedule 80 steel pipe (also available is SS, Alloy 20, Hastelloy, etc.) is protected from corrosion by an extruded, high density, chemically inert PTFE liner and jacket which are fused together at the bottom. Both the liner and the jacket are applied in a manner which compensates for thermal expansion, using the Resistoflex Thermalok process.

Warning: Exceeding the maximum recommended service temperature and/or pressure, or recommended unsupported length can result in premature failure and personnel and/or equipment hazard.

*Use Resistoflex Reducing Flanges to adapt for larger nozzles.
**Recommended maximum length for mild agitation is shown as a general guide for liquids having about the same density and viscosity as water. For longer lengths, or more severe operating loads (density, viscosity and velocity of fluid at the pipe), a larger size of internal bracing should be employed.

Note: The nozzle flange sizes shown are the only sizes available. To connect a dip pipe to a larger nozzle, a reducing flange must be used. Contact factory for more information as not all standard reducing flanges are suitable.

Solid PTFE dip pipes are also available.
