Carcass Floating Hoses are a reliable and durable solution for exposed offshore installations. A marine hose can be a single-carcass or double-type. Double Carcass Hoses are flexible hose which has two carcasses that are made of textile-reinforced bonded elastomers and designed so that if the main carcass fails, The first carcass serves as a conduit for the fluid to be conveyed and the secondary carcass contains space for fluid retention and protects the ambient environment. The double carcass hose can handle higher flow rates compared with a single carcass hose.

Double carcass hoses are an important safety component for marine applications used in the transport of crude oil fluids that can be polluted the environment. These hoses have the ability to contain a leak if it occurs because they can be designed to include an alert device in case of failure. WIHO industrial is a manufacturer and supplier of Single Carcass Hose comply with GMPHOM and is manufactured under ISO certification. The hose we provide is made of multiple plies of high-performance steel and rubber materials suitable for work in extremely rough conditions in long-lasting applications. The double carcass hoses supplied by WIHO Industrial are made from some materials and are designed with various features to meet specific needs.
