Flexible Pipe: A Brief Discussion By The

Manufacturers

DefinitionA composite construction assembly of a metal or polymer pipe body and fittings containing layered

materials, which behaves as a pressure conduit allowing deflections of large amplitude without

bending or stressing the pipe. The product is available either as a continuous length or in parts joined together

by connectors.

Material PropertiesLinear elasticity – steel, reinforced steel, aluminium, thermoplastic.

Non-linear elasticity – solid-wall and profile-wall polyethylene of high density, PVC, glass-reinforced polymer mortar.

Influenced by strain rate, service temperatures, constant load, and creep (visco-elasticity).

Designed to be strong, sturdy and serviceable.

Flexible pipes need to stay round during manufacture, delivery, handling, installation, and application.

Quality is measured by stiffness and flexibility factor.

Load at which deflection is noticed is determined using the parallel plate test.

ApplicationsBuried or unburied flexible pipes can be used for various offshore and onshore applications, including:

•Culverts•Sewerage•Water supply•Oil and gas pipelines•Soil-interaction pipe systems•Drainage and sanitary solutions•Deep and ultra-deep subsea drilling

AdvantagesThe Manufacturers of Flexible pipes in India have revealed the following advantages:

•High levels of sustainability•Heavy duty•Easy to install and use•Leak-proof•Lightweight•Mechanical strength•Corrosion resistant•Chemical resistant•Pressure resistant•Low abrasion of inner walls•No storage and handling damage•Low cost of transportation•Recyclable
