Chemical Double Containment Trench Drain

The Double Containment version of our Standard Trench Drain – for areas with hazardous chemicals or bio waste.  The KSBC150DC channel is designed for the Chemical and Pharmaceutical industry and has been used also in the Nuclear Industry and in the Beverage Industry where there are high concentrations of acidic discharge.

This is supplied pre-sloped.  Widths are described using the internal dimension – 5.9″ (150mm) for the narrowest trench measures the i.d. where the grate sits.

Channel has a start depth of 4.9″ (125mm) with 1:150 fall built-in gives an ending depth of 7.5″ (191mm) on a 33ft (10m) run. For Beverage, Pharmaceutical and Chemical plants, a high flow rate will be required and a KVDC215/4”/6” or KVDC315/6”/8” outlet box welded to a central point or to an end will be required.  The majority of American Multinational Pharmaceutical plants use SCH10 piping, and the standard grade of stainless is grade 316.  Flow rates of 79 US Gallons/Min (5 litres per second) minimum will then be achieved and this rate can be increased to 316 GPM (20 l/s.)

The Turnout/Turndown edge profile accepts concrete infill, and for particularly heavy load areas (>10T forklifts) this edge profile readily accepts a box section infill or a solid bar infill. Trench Drains as standard are supplied with fully welded flanges and gaskets and fully welded ends.  Corners and T sections are supplied fully welded.  Outlet boxes are supplied fully welded and Contractor only connects straight lengths to straight lengths using flanges and gaskets.  Where site welding is preferred, contractor again only connects straight length to straight length, but flanges are stepped back slightly to allow flush joining to help site welding of lengths.

Ideal manufacturing sizes are in 9.8ft (3.0m) lengths or for very large quantities 19.6ft (6.0m) lengths (reduces site time but adds to transport costs). The edge profile is designed to accept a 1″ (25mm) deep grating as standard.  This can be reduced to 0.79″ (20mm) on request. Typical gratings are Plain Mesh for pedestrian areas in factories, Ladder Grating for forklift traffic area in factories.
