INDUSTRY PROFILE IMPORTANCE OF PIPE INDUSTRY We shall smelling at the prefatorial data about charge plates and in particular those properties, which atomic number 18 of use in practical working with plastics. Plastics be manmade materials. The oldest untoughened materials for producing plastics atomic number 18 carbonaceous materials obtained anatomy coaltar (benzene, phenol). Today the legal age of raw materials are obtained form Petro Chemical sources and they can be economically produced in large-scale quantities. Plastics be in possession of 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 fish 2) fantabulous mould ability 3) Attractive colours 4) Low postal code requirement for convention 5) Low labour & represent of manufacture 6) Low maintenance 7) spunky strength weight ratio 8) Corrosion resistance 9) Aesthetic without surface interposition Although plastic have strength to weight ratio, they are non as strong as metals and deform permanently at a lower place load. They cannot project extremely richly or low temperature equivalent 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 racy strength feeling plastics and they at times replace steel. berth MATERIALS & CHEMICALS The important raw material in manufacturing of pipes PVC rosin (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 atomic number 20 carbonate 8) Tritanium dioxide 9) Carbon black colour Compositions of raw materials & chemicals (As per ISI 4985—88) for the batches are as follows.
