Band-Seal Chemical Couplings is a range of versatile, flexible couplings used for jointing pipes of both similar and different materials and sizes. The couplings are especially suitable for drains, sewers and underground pipelines. The extensive range connects pipes from 35mm to over 2000mm nominal size (DN), to other pipes of the same of different sizes and materials.

The Band-Seal range of chemical couplings consists of moulded synthetic elastomeric sleeves and stainless steel clamping bands. Standard chemical couplings also include a stainless steel shear band and fluoropolymer liner.

The Band-Seal Chemical Coupling Range
The range of Band-Seal chemically resistant couplings offers the chemical and process industries the advantage of a modern, mechanical, flexible jointing system for any plain-end pipe system.

Elastomeric Sleeve - Manufactured in high grade EPDM or Nitrile elastomers conforming to EN681-1.

Clamping Bands - Manufactured in a high corrosion resistant austenitic stainless steel to EN10088. Where external contamination demands a higher quality stainless, this can be supplied to order.

Fluoropolymer Liner - A one-piece seamless FEP element located within the elastomeric sleeve. Expanded PTFE secondary seals ensure a leak tight joint between the FEP and the pipe. For the best results and to ensure a close fit between the liner and pipe the FEP liner is heat shrunk on site. The liner and seal are chemically inert and resistant to virtually all chemicals including solvents.

Standard Chemical Couplings
Used to connect pipes sizes up to 2000mm outside diameter where resistance to shear loads is required applications include:

Jointing FCR and HT plain-ended pipe systems Repair and maintenance of existing chemical pipelines.

Connections between pipes of different materials or sizes (bushes may be required in these circumstances)

Making connections by the insertion of new junctions to an existing pipeline

Reconnection of laterals on renovated pipelines

Introducing rocker or hinge pipes outside manholes or structures.

Adaptor Couplings
Provide a method of directly jointing pipes of differing outside diameters, without the need to use bushes. These couplings are suitable for connecting other types of pipes including cast iron and metal pipes (up to a maximum outside diameter of 420mm).
