Pre-Cured Sleeves For High-Pressure Pipes
Clock Spring is one of several composite wrap approaches developed by inventor Norman C. Fawley of NCF Industries Inc. (Santa Maria, Calif., U.S.A.). The concentrically-coiled, glass fiber-reinforced polyester composite sleeve was devised with support from the Gas Technology Institute and the gas pipeline indu

Low-pressure air cans, designed to add buoyancy to a spar platform’s riser string, are good candidates for composite materials. Up to 12 ft/3.7m in diameter and from 30 to 60 ft/9.2 to 18.5m long, the hollow structures support the riser weight and take load off of the platform’s hull. Typically installed insid

Typical FRP pipe is reciprocally filament wound with a fiber angle of ±54.75° relative to the longitudinal (0°) axis. This architecture satisfies stress loads in both the circumferential (hoop) and longitudinal (axial) directions for most pipes and pressure vessels. It withstands the in-use pressure, ther
Read MoreSome Design Issues
A variety of resins can be used for offshore applications, depending on the requirements for the final product. General-purpose polyester offers a low-cost option that provides greater corrosion resistance than steel. Isophthalic polyester provides somewhat better corrosion resistance, while vinyl ester is pre
