uPVC Fittings

Introduction

Technology and performance have made PVC pipes the most popular choice for water and sewer lines. It has been proven that plastic pipes are the ideal products for today's extensive continuum of commercial, residential and industrial sector applications for withstanding resistance to a wide range of chemicals, heat and pressure.

uPVC or unplasticized polyvinyl chloride is on of the most widely used thermoplastic materials, due to its flexibility of usage and competitive price. It is manufactured by the petrochemical industry who produce dichloride from ethane and chloride and apply pyrolisis above 400c to cause splitting into vinyl chloride and hydrochloric acid.

The basic polymer is mixed with additives such as colour, filler, lubricants and stabilizers in accordance with recipe determined by the properties of finishded products. The mix of compound is transported to either extruders or injection molding machines to be converted into the end product

uPVC pipes and fittings will not deteriorate under attack from bacteria or other micro organism and will not provide food source to micro/macro organism and fungi. These pipes and fittings are also suitable for chemical industries as they have chemical resistance to most acids and alkalies. uPVC, being themoplastic materials are prone to variance in physical properties based to variation in temparature. It is important to take into account the application of end use and temperature conditions when selecting class and rates of pipes (Wall Thickness of Pipe)

Sailent Features of uPVC Pipes

1. Non-Corrosive: uPVC pipes are not attacked by acids, alkalis, oil and salts etc., because uPVC material is chemically inert.
2. Insulator: uPVC is an excellent insulator and is used as an insulation on electrical wires & cables and as ducts for electrical and communication cables
3. Mechanical Strength: uPVC pipes will not dent or flatten under pressure because of high tnesile & impact strength
4. Low Thermal Conductivity: uPVC has low co-efficient of thermal conductivity & because of this there is no heat loss or gained
5. Fire Proof: uPVC pipes will not support combustion and in the event of fire, flames are unable to spread along.
6. Flow Efficiency: uPVC pipes have smooth & glossy surface which discourage the formation of scale and deposits.
7. Light Weight: uPVC pipes are of less weight compared to cast iron, asbestos & cement pipes. This reduces manapower & installation operation cost
8. Sanitary: uPVC pipes are completely non-toxic & does not affect the taste, smell or colour of the liquid nor reacts with any liquid to cause a precipitant
9. Cost: uPVC is one of the least expensive materials used in manufacturing of pipes and fittings
10. Acuosticity: uPVC pipes are good acousticity compare to other pipes
11. C02 Features: Environment friendly
12. Weathering Effect: uPVC pipes are good weathering effect and UV resistance
13. Chemical Resistance: uPVC pipes and fittings are chemical / Acid resistance

Applications of uPVC Pipes

1. Soil & Waste Discharge System
2. Drainage Waste: uPVC pipes are useful for waste lines of corrosive chemicals
3. System Water Network System
4. Aboveground and Underground non-pressure drainage/sewerage application
5. Ventilation: uPVC pipes and suitable for ventilation for building & factories
