Double Contained Channel

The Double Contained version of our Standard Box Channel – for areas with hazardous chemicals.  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.

Comes with a built-in fall as standard.  Widths are measured by using the Grating width, and the actual channel width adds 20mm to either side of the grating for a turnout/turndown edge profile. eg a KVBC150 channel takes a 150mm wide grating and physically measures 190mm outside edge to outside edge.

Channel has a start depth of 125mm with 1:150 fall built-in gives an ending depth of 191mm on a 10m run with a spigot at the end of 158mm with a spigot in the centre. For Beverage, Pharmaceutical and Chemical plants, a high flow rate will be required and a KVDC215/4”/6” or KVDC315/6”/8” gully 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 5 litres per second minimum will then be achieved and this rate can be increased to 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. Channel as standard is supplied with fully welded flanges and gaskets and fully welded ends.  Corners and T sections are supplied fully welded.  Gullies 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 3.0m lengths or for very large quantities 6.0m lengths (reduces site time but adds to transport costs). The edge profile is designed to accept a 25mm deep grating as standard.  This can be reduced to 20mm on request. Typical gratings are Plain Mesh for pedestrian areas in factories, Ladder Grating for forklift traffic area in factories.
