Method for Building a Slip 'N Slide. The method for creating the Slip 'N Slide is exceptionally simple. Construction should take no more than one hour, and the slide is ready for use immediately. Note that it is easier to work with plastic sheeting on days when there is little or no wind.
Nine reasons why hydraulic hoses fail Key concepts Hose life is cut short by factors that can be controlled. Poor routing is a leading cause of hose failure. Don't operate hoses at their pressure and temperature limits. Hoses used in hydraulic systems have a predictable future. They won't last forever. How do you determine how long a hose will last? The actual service life of a hose assembly in a given application is determined by a variety of factors.
Corrosion can cause failures by thinning the wall over a large area or localized pitting. Both external and internal corrosion can lead to failures, but the widespread use of surface at the failure origin of a 20-inch gas line that failed shortly after the operating pressure was increased. The failure resulted from internal pitting corrosion on the bottom of the pipeline that significantly reduced its wall thickness. Figure 7 shows the depth or the pitting on a polished cross-section cut transverse to the fraction (arrow). Another form of corrosion, stress-corrosion cracking, can also lead to failures. Figure 11.
