Biltong biltong was made during the cold winters of the South African Highveld for best results. The cold, dry air typically dried out the biltong much more effectively, and in the best possible food safety environment. Mould and bacterial risk are at a natural minimum, and thicker biltong cuts can be hung to dry slowly for a richer texture, fuller flavor and dark colour. Heat has only been introduced into the process in recent years, and traditional biltong makers maintain that heat makes for an inferior end result. Due to increased risk of bacterial and fungal growth, the heated method, such
Cured-in-place pipe from 6 CIPP installations. Cured-in-place pipe A cured-in-place pipe (CIPP) is one of several trenchless rehabilitation methods used to repair existing pipelines. CIPP is a jointless, seamless, pipe-within-a-pipe with the capability to rehabilitate pipes ranging in diameter from 0.1 to 2.8 meters (2–110 inches). As one of the most widely used rehabilitation methods CIPP has applications in sewer, and chemical pipelines. A resin-saturated felt tube made of polyester, fibreglass cloth or any of a number of other materials suitable for resin impregnation, is inserted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole
