"Piping" sometimes refers to Piping Design, the detailed specification of the physical piping layout within a process plant or commercial building. In earlier days, this was sometimes called Drafting, Technical drawing, Engineering Drawing, and Design but is today commonly performed by Designers who have learned to use automated Computer Aided Drawing / Computer Aided Design (CAD) software.,
Internal erosion of soil particles from within a dam by water that seeps through the dam is one of the most common causes of failure of levees and earth dams.
Internal erosion is especially dangerous because there may be no external evidence, or only subtle evidence, that it is taking place. Usually a sand boil can be found, but the boil might be hidden under water. A dam may breach within a few hours after evidence of internal erosion becomes obvious.
Internal erosion manifests by the migration of soil particles by suffusion or piping.
Piping is induced by regressive erosion of particles from downstream and along the upstream line towards an outside environment until a continuous pipe is formed.
Suffusion is the migration of soil particles through the soil matrix.
In sewing, piping is a type of trim or embellishment consisting of a strip of folded fabric inserted into a seam to define the edges or style lines of a garment or other textile object. Usually the fabric strip is cut on the bias. It may be made from either self-fabric (the same fabric as the object to be ornamented) or contrasting fabric, or of leather.
Today, piping is common on upholstery and decorative pillows, but it is also used on clothing. Piped pocket openings, garment edges, and seams are characteristic of Western wear.
