Flexible Hoses Aren’t Fire Resistant
Firefighters are accustomed to using flexible, durable and lightweight hoses. However, many people don’t know that these hoses aren’t fire-resistant. A team of researchers at Worcester Polytechnic Institute is working on a fire-resistant hose. They are using PTFE, perfluoroalkoxy alkane or fluorinated ethylene propylene to make the hose. This research will hopefully meet aerospace standards. 1. High Temperature Resistance These hoses are used to protect electrical cables, wires and other equipment from high temperature environments, such as in steel plants, smelters and glass factories. They can also be used to protect hydraulic and oil lines. These hoses are composed of a polyester jacket and rubber lining. The polyester jacket is woven with warp in polyester staple and weft in polyester filament. The lining is made of natural rubber or PVC. It is lightweight, flexible and has good resistance to rolling and ageing. A radially outer second rubber layer is added for contact protection with the external conditions. 2. High Pressure Resistance Fire-resistant hoses are designed to work under high pressure. They are also able to resist abrasion, cutting, gouging, corrosion, weather and oil. They are made of silicone materials that don’t encourage electrical conductivity and have low toxicity levels. In…

Choosing the Right BOP Diverter System
During drilling operations on surface platforms and jackup rigs, a diverter system is used to control shallow gas kicks. Whenever a kick is detected the system is energized to seal around drill pipe and divert it safely away from the wellhead. The diverter system includes a blowout preventer connected in series above a spool having an annular piston. The piston moves upwardly, sequentially opening an outlet passage in the spool to fluid communication with a vent line. Hydraulic Hose A hydraulic hose is a critical part of any oil and gas drilling rig, as it transports the pressurized fluid that powers equipment and keeps the BOP working properly. It’s available in a wide range of materials, and the best choice depends on the specific application. There are three basic parts to any hose: an inner tube, a reinforcement layer and a protective outer cover. The inner tube is typically made from a thermoplastic or synthetic rubber that’s compatible with the liquid it carries. The reinforcement layer can consist of textile braid for lower-pressure applications or high tensile steel wire for higher pressure and better abrasion resistance. The final cover is typically designed to be abrasion, ozone and oil-resistant. It protects…
