Product of the Week: Bottom Discharge Connection Fittings

Product of the week: Bottom Discharge Connection Fittings

As we’ve discussed, when a tank has a discharge opening below liquid level, this bottom outlet will normally require 3 points of closure. In the previous two Product-of-the-Week segments, we reviewed the first point of closure which is the Internal Valve and then the second point of closure is the External Valve.

The third point of closure on a bottom discharge assembly is typically a 3” BSP spigot flange with cap.  BSP stands for British Standard Pipe thread, and this is the tank container industry standard. Click here for more information on BSP threaded connections and how BSP threads differ from our U.S. standard of NPT threads.

Naturally, the first thing that a number of our domestic customers want to do is replace the standard 3” BSP spigot flange with something else so that they can adapt to it in their plant.  We offer a number of different options ranging from new connection flanges, to simple “spin-on” adapters that will screw onto the existing 3” BSP threads to give customers either a 3” NPT connection, a 2” NPT connection, or a 3” camlock connection.

Tank Service Inc. can also custom-fabricate any bottom discharge fitting you might need, if one of our off-the-shelf products won’t meet your requirements.

For more information about bottom discharge fittings, please call us at (281) 542-9176, visit our website, or click here to read more.

Thanks for checking in!  See you next time on Product-of-the-Week!

Offshore tanks in Houston Texas

Over the last few months, Tank Service Inc has received a number of questions about offshore equipment, specifically offshore chemical tanks.  Although we can furnish this type of equipment, the down side is that you will have lead times associated with this.  Most of you may not have that much time to secure a project, so we have listened and currently have 1x 1100 gallon offshore tank in stock here in Houston ready to go.

Further, DNV design is not something yet required here int he US but it will slowly get mainstreamed as it already has in other parts of the world.  So what does that this mean to you?  This tank is already DNV designed and approved, so you’ll have no issues if you plan on operating it somewhere else.

Capacity: 4500 Liters

Frame dimensions: 2300mm X 2300mm X 2400mm

Pressure design: 3.0 BAR MAWP

Barrel Material: 316 SS

Please Email me for a full set of specifications for this offshore tank.

This T7 offshore chemical tank is currently available at Tank Service Inc in Houston, Texas.

MINI ISO Tank Containers- offshore practice

I was talking to gentleman earlier today concerning offshore fuel storage tanks; the requirements called for the ability to lift the tanks off the supply boat to the platforms.  MINI ISO tanks are commonly used for offshore chemical shipments and or fuel distribution.

What about size?  Well, they are called MINI ISO Tanks for a reason; they happen to be half the physical size of a full ISO tank.  10ft x 8ft x 8ft tall.  The options currently available are used carbon steel units, or build new ones to your specific needs.

Note:  MINI ISO tanks have the physical properties noted above, regular offshore tanks can vary in frame design, size and orientation.

Here are a few pictures…
