Extrusion Processing Guides-2 The feed zone temperature controls the compound sticking to the barrel wall, otherwise known as the bite. Too much bite will lead to overheating of the compound and too little bite will lead to poor output. The die temperature will also influence output and will have an effect on the dimensions of the extrudate. A cold die will restrict flow where as a too-hot die will affect di…

Applications of PVC pipe - Coal Seam Gas Coal seam gas production is water hungry business. Millions of gigalitres of water are brought to the surface, removed from the coal seam in order for the gas to be extracted. Conservative estimates suggest coal seam gas wells could draw 300 gigalitres of water from the ground each year from the some 40,000 coal seam gas wells estimated for Australia. Once the water is brought t…

Benefits of PVC Pipes-2 Coefficient of FrictionWhen piping systems are designed one of the main concerns is flow rate and pressure. PVC Pipes provide smoother wall surfaces that reduce fluid friction and resistance to flow. This hydraulic smoothness inhibits slime build-up in sewers and virtually eliminates tuberculation and encrustation in water distribution mains. The end results are significantly lo…
