Heavily corroded aluminium waste tank from a Moody yacht

Over the past two decades, TEK-TANKS designers and engineers have developed a plastic tank construction system using high strength, advanced polyethylene materials that overcome the persistent corrosion and weight problems of mild steel and the mechanical failure of flexible bag style tanks. Some of our current work is building replacement plastic tanks for boats previously fitted with mechanically unreliable flexible bags or stainless and aluminium tanks with electrolysis problems.

Taste Free Water

The particular specification of polyethylene (food grade quality) which TEK-TANKS use will not corrode and provides clean, taste free water for the galley.

Computer Aided Design and Manufacture

After being computer designed on our CAD system, components for each plastic water or plastic waste tank are cut to exact shape and size on our CNC router. These panels are then fitted together and welded in place using the latest hot gas extrusion welding systems.Hot Gas Extrusion Welding

 

 

Baffles For Strength And Security

TEK-TANKS standard specification includes baffles placed approximate every 300 mm. On larger plastic tanks these are locked into position by means of an interlocking pin and ribs situated under the top panel. This design feature prevents the top of the plastic water or waste holding tank from lifting when under pressure.

These carefully planned internal baffles also perform two additional important functions. Firstly, they introduce immense rigidity to the design of the plastic tank, and secondly, they cleverly limit the dynamic movement of contents, thus minimising the destructive pounding forces against the plastic tank body.

Inspection HatchesTEK TANKS (112)WEBSIZE

These are high quality proprietary hatches with a large O ring seal. Where height is a problem then a 10mm thick hatch cover with a rubber neoprene seal would be used. All hatches can be supplied as an optional extra. Where cross baffles are adjacent to an inspection hatch, the baffles have on average eight inch diameter cut-outs to facilitate cleaning and maintenance.

Custom Design And ProductionDale Grey Small

Bespoke plastic water and waste holding tanks built from rigid polyethylene lend themselves to one-off production because there are no expensive mould tools to build. Plastic tanks are of all welded construction and built to the customers own design, but to TEK-TANKS demanding and proven specifications. Polyethylene cannot be easily curved, but multifaceted shapes normally solve most design problems. Please bear in mind when designing your plastic tank that the more complicated the shape, the more expensive the tank.
