Pipes/piping polyvinyl chloride

Plastic piping [polyvinyl chloride (PVC)] does not show corrosion as in the case of metal piping, but the properties of plastic piping deteriorate over time. In severely corrosive soils PVC piping may be selected rather than a metallic piping because it is inert to the chemical conditions. PVC has a lower density than steel and iron and hence it is relatively easy to handle in the field. However, PVC has lower strength and traditional welding is not possible. PVC has been used for a relatively short time, compared with steel and iron water lines. Thus, there is limited data on the expected service life of PVC pipelines, and calculations of comparative total life-cycle costs are not possible. [Pg.154]

Methyl bromide, when dry (<100 ppm water), is inert toward most materials of constmction. Carbon steel is recommended for storage vessels, piping, pumps, valves, and fittings. Copper, brass, nickel, and its alloys are sometimes used. Aluminum, magnesium, zinc, and alloys of these metals should not be used because under some conditions dangerous pyrophoric compounds may be formed. Many nonmetallic materials are also useful for handling methyl bromide, but nylon and polyvinyl chloride should be avoided. [Pg.294]

Polyvinyl chloride Polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) pipe and tubing are available in sizes 12 in and smaller for PVC and 4 in and smaller for CPVC. They have excellent resistance at room temperature to salts, ammonium hydroxide, and sulfuric, nitric, acetic, and hydrochloric acid but may be damaged by ketones, aromatics, and some chlorinated hydrocarbons.

As production increased, new coating materials for pipe protection evolved and a variety of. synthetic materials became available. In 1950, continuous-laid pipelines in America and Italy were coated with polyvinyl chloride tapes applied... [Pg.7]

FRP, plastics (polyvinyl chloride, polyethylene, polypropylene, and other similar materials), and rubber are general use and are recommended for alum solutions. Care must be taken to provide adequate support for these piping systems, with close attention given to spans between supports so that objectionable deflection will not be experienced. The alum solution should be injected into a zone of rapid mixing or turbulent flow. [Pg.94]

Polyvinyl chloride (PVC) is one of the most widely used thermoplastics. It can be extruded into sheets and film and blow molded into bottles. It is used in many common items such as garden hoses, shower curtains, irrigation pipes, and paint formulations. [Pg.332]

When water (a Newtonian liquid) is in an open-ended pipe, pressure can be applied to move it. Doubling the water pressure doubles the flow rate of the water. Water does not have a shear-thinning action. However, in a similar situation but using a plastic melt (a non-Newtonian liquid), if the pressure is doubled the melt flow may increase from 2 to 15 times, depending on the plastic used. As an example, linear low-density polyethylene (LLDPE), with a low shear-thinning action, experiences a low rate increase, which explains why it can cause more processing problems than other PEs. The higher-flow melts include polyvinyl chloride (PVC) and polystyrene (PS). [Pg.447]

Competition, at each stage in the plastics industry, is in their raw materials. Many monomers can be made from alternate raw materials such as polyvinyl chloride that may begin with either ethylene or acetylene. Most plastic products may be made from a variety of plastics such as pipe that may be extruded from PVC, polyethylene, ABS, and so on. [Pg.578]

Ten 10 cm diameter by 305 cm long polyvinyl chloride pipes were supported on wooden frames In the greenhouse. Fifty seven 3.5 cm diameter holes were drilled In a line along the length of each pipe. One end of each pipe was fitted with a fiberglass screen the other end was fitted with an elbow... [Pg.235]

We find polyvinyl chloride in so many applications because we can formulate it to be rigid, flexible, or any intermediate hardness required. Rigid polyvinyl chloride is used to manufacture siding, pipes, fences, gutters, window and door frames, credit cards, and many other extruded... [Pg.349]

Chemical/Physical. In a laboratory experiment, it was observed that the leaching of a vinyl chloride monomer from a polyvinyl chloride pipe into water reacted with chlorine to form chloroacetaldehyde, chloroacetic acid, and other unidentified compounds (Ando and Sayato, 1984). [Pg.1147]

Antimony has few other uses except as an alloy to harden other materials. One recent development was to add antimony oxide to polyvinyl chloride (PVC pipe) to act as a flame retardant. [Pg.219]
