Stainless Steel Bulkheads
Used in rugged environments. Bolted through the tank, with 4-bolt and 6-bolt configurations as the standard types depending on fitting size.

Fittings & Options
The fittings we install to connect your piping to HDPE, polypropylene and PVDF tanks, from gasket-free welded couplings and flanges to bulkheads and sanitary tri-clamps.
Pipe connection fittings
Welded couplings provide secure threaded fittings for plastic tanks without the need for gaskets. They also allow vertical pipe connections on sloped areas of the tank dome.
Pipe connection fittings
Welded flanges provide secure fittings for plastic tanks without the need for gaskets. We use thermoplastic welding to fuse flanged fittings to our tanks in a wide range of sizes.
Pipe connection fittings
Standard bulkheads provide a way to attach pipes to a tank. They are usually threaded (FIPT) and made from stainless steel, polypropylene, PVC or CPVC. Other metals and plastics are available but much less common.
Used in rugged environments. Bolted through the tank, with 4-bolt and 6-bolt configurations as the standard types depending on fitting size.
The most commonly used bulkhead: reliable and reasonably priced.
Available in threaded and socket styles. Socket types allow PVC or CPVC pipe to be glued in place, which, when done properly, gives a more secure seal than a threaded connection.
Used on the tank dome, where a standard bulkhead’s threads would sit at an odd angle. A ball with pass-through threads adjusts to meet the plumbing. Top of tank only, not for use where liquid contacts the fitting. Polypropylene or PVC.
Pipe connection fittings
Bolted flanges provide a secure way to attach pipes to a tank and are often used in industrial applications. They are usually made from PVC, CPVC, polypropylene and stainless steel; other metals and plastics are available but much less common.
Spool flanges offer a secure connection to the tank and an extended flange face for attaching valves or pipes. Our PVC and CPVC spool flanges have loose flange rings on the extended flange for easier connection to pipe or valve flanges.
Pipe connection fittings
Screw-on PVC bulkhead flanges offer safe, quick pipe connections for standard-wall plastic tanks. We use Spears Schedule 80 bulkheads or their equivalent.
Thread × Thread is supplied unless otherwise specified.
Some larger sizes are not available on small-diameter tanks.
Pipe connection fittings
When sanitary Tri-Clamps are the preferred fitting, we use a combination of welded couplings and Tri-Clamp adapters.
Bonds to the tank material.
Changes the connection to a Tri-Clamp.
Half couplings can replace full double-threaded couplings to reduce threaded surface.
