The new Flexigas DS (Double Sleeve) is a double layered, flexible gas piping system. Said to be ideal for ventilating an unvented void, a riser, or situations requiring a sleeve to pass through solid walls, floors or a cavity wall, the pre-sleeved CSST solution is suitable for both domestic and commercial installations.
Traditionally, gas engineers running pipes through unvented areas would have to sleeve CSST through a second duct/sleeve for ventilation purposes. Flexigas DS saves time by providing a pre-sleeved version already assembled on the roll, finished in a PE coating to allow for meter marking.
Flexigas DS is flexible enough to be bent to 90 degree angles by hand, but with a hard durable coating that protects the inner pipe. The pipe complies with BS 6891 and IGEM regulations, and comes in lengths of 25, 50 or 75m as standard, but can also be cut to custom lengths on request. Flexigas DS is compatible with the full range of Flexigas fittings, from sizes DN15 to DN50.
