INDUSTRY PROFILE IMPORTANCE OF PIPE INDUSTRY We shall life at the prefatorial data about charge plates and specially those properties, which be of use in practical working with plastics. Plastics be manmade materials. The oldest untoughened materials for producing plastics are 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 need 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 saddle 2) delicate 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 res istance 9) Aesthetic without surface intervention Although plastic have strength to weight ratio, they are not as strong as metals and deform permanently chthonic load. They cannot project extremely richly or low temperature equal 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 exalted strength feeling plastics and they at times replace steel. mooring MATERIALS & CHEMICALS The important raw material in manufacturing of pipes PVC rosin (Poly Vinyl Chloride).
Chemicals 1) Tbls ( Trib! asic 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 raw materials & chemicals (As per ISI 4985—88) for the batches are as follows.
