Copyright Goodheart-Willcox Co., Inc. 416 Fluid Power Manufacturers provide a selection of hose types to meet various system working conditions. Many of these are built to meet standards established by indus- try standardizing groups. Ideally, hoses should be no longer or larger in diameter than necessary to supply the compressed air needed at a work location, Figure 16-27. This ensures the delivery of air with minimal pressure drop. It also ensures minimal hose and installation costs. However, in work conditions that are often less than ideal, this may not be possible. These points should be consid- ered when working with hose to minimize installation costs and pressure drops: • Hoses should be no longer than necessary. • Hoses should be no larger in diameter than necessary. • A minimum number of fi ttings and couplings should be used. • Lay out lines to eliminate kinks and reduce the number of bends.
