Welded concertina covers and bellows are manufactured in polyurethane on nylon fabric and produce strong, aesthetically pleasing watertight seams that prevent ingress from oil and fine particulate.
The fabric is extremely durable. It is UV and ozone stable and it is rated for offshore applications. With welded seams there is no stitching to wear and polyurethane on nylon fabric has excellent resistance to abrasion.
The combination is ideally suited for use on grinding applications, bulk transfer of aggregate and selective food products, heavy duty vehicle suspension units, water treatment and offshore industries. Welded bellows will produce a complete seal with good open-to-closed ratios.
They are able to withstand low to moderate internal and external water and air pressure.
