DS - Model BL-T -Pipe Sealing Systems

• DS BL-T is in accordance with the requirements of DIN EN 681-1 / DIN 4060 [88] (seals made from elastomers) and the FBS quality guidelines.
• DS BL-T pipe connections fulfill the criteria of DIN EN 1916, method 1-4.
• DS BL-T can be easily connected with the pipe. It is mounted on the base ring and is anchored during manufacture of the pipe in the pipe socket. After removal of the base ring the DS BL-T socket is ready for installation.
• DS BL-T can be used for all pipe production machines with core vibration and radial pressure roller head.
• DS BL-T requires special base rings which determine by their shape the seat of the seal.
• DS BL-T can be supplied for pipes DN 300 to DN 1500 in 3 specific cross sections.
• DS BL-T lines the inner wall of the socket up to the socket face. Lining the entire socket space prevents deposits of dirt and water (ice formation) behind the seal. Removal of a protective strip is not required.
• DS BL-T pipe connections resist high shearing forces..

• Forms an integrated unit together with the pipe, which enables a quick and safe installation.
• The wedge shape of the seal body eases the pipe centering.
• Thanks to the deep, fully lined socket the pipe connection has a large freedom of movement while maintaining optimal water tightness security.

DS BL-T is composed of styrene -butadiene rubber (SBR), hardness 50 ± 5 IRHD. The material resists the usual stresses caused by wastewater. In case of content of light liquids (oil, petrol, fuels) in the sewage water it is recommended to use seals out of acryl-nitrile-butadiene-rubber (NBR), which has a higher resistance against light liquids.
