Glass Lined Dip Pipe (Sparger) for Columns and Chemical Reactors

Dip Pipes are used to introduce products into columns or reactors. They are designed to provide the ultimate in corrosion-resistant, non-contaminating construction to 500°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. Dip pipes are fabricated per ASTM A836 / A836M – 14.

They are designed to withstand high mechanical loads imposed by mixing or agitation in process vessels and reactors. The schedule 80 steel pipe is protected from corrosion by a chemically inert glass lining which is fused onto all wetted surfaces at 1500F. The Dip Pipe and jacket are assembled to compensate for thermal expansion.

Dip pipes have a wide array of uses. Typically they are used to charge a liquid or gas into a reactor below the liquid level often in a specific zone.  Some applications rely on Dip pipes to extract samples from the reactor as part of a sampling system or to drain liquid from a vessel without the need of side or bottom outlet. Glass lined dip pipes are specified in applications requiring the chemical resistance of glass, nonstick or purity of product.

Standard dip tubes can be supplied in a variety of diameters and length configurations. Maximum recommended unsupported length for agitated service is shown in the table below (a general guide only). GTI will review your specific service conditions and advise a suitable dip tube construction.

GTI dip pipes are manufactured from a carbon steel pipe of schedule 40 or schedule 80 pipe with 150 psi ANSI standard flanges. All wetted surfaces are glass. The bottom of the dip pipe is flared with a generous radius. Our advanced manufacturing techniques enable us to produce dip pipes without any pinched or welded ends eliminating any potential weak point.

Dip pipe may built to custom dimensions. Below is a standard table for dip pipe selection.
