INDUSTRY PROFILE IMPORTANCE OF PIPE INDUSTRY We shall fancy at the prefatorial data about charge plates and particularly those properties, which atomic number 18 of use in practical working with plastics. Plastics be manmade materials. The oldest untoughened materials for producing plastics be carbonaceous materials obtained anatomy coaltar (benzene, phenol). Today the bulk of raw materials are obtained form Petro Chemical sources and they can be economically produced in large-scale quantities. Plastics welcome changed our world and day-by-day they are becoming important. They own their winner to whole series of advantages which they have over conventional materials much(prenominal) as 1) Light weighting 2) fine mould ability 3) Attractive colours 4) Low postal code requirement for convention 5) Low labour & appeal of manufacture 6) Low maintenance 7) spunky strength weight ratio 8) Corrosion resistance 9) Aesthetic without surface manipulation Although plastic have strength to weight ratio, they are not as strong as metals and deform permanently to a lower place load. They cannot project extremely richly or low temperature resembling materials and new(prenominal) metals such as refractory bricks. Modern invention of ice-skating rink or carbon-black as reinforcing fillers pave the way for making utmost strength feeling plastics and they at times replace steel. tart MATERIALS & CHEMICALS The important raw material in manufacturing of pipes PVC resin (Poly Vinyl Chloride). Chemicals 1) Tbls ( Tribasic lead Sulphate 2) Dbls (Dibasic lead sterate 3) Ls(Lead sterate 4) Cs ( atomic number 20 sterate 5) Sa ( Steric acid 6) Paraffin wax 7) CaCO3 (Activated calcium carbonate 8) Tritanium dioxide 9 ) Carbon black colour Compositions of r! aw materials & chemicals (As per ISI 4985—88) for the batches are as follows.
