POLYPROPYLENE AS A MATERIAL OF CHOICE

A. General properties of Polypropylene: Polypropylene (PP) is a thermoplastic from the polyolefin group. PP is a semi-rigid, translucent polymer with good toughness and weather resistance properties. It has low water absorption and is easily moulded to desired shapes. Polypropylene is a largely non-polar, partially crystalline thermoplastic with a crystallinity of 60 to 70%. PP has a density of 0.90 to 0.91 g/cm3 which is amongst the lowest densities for all plastics. PP has a non-swelling and insoluble surface; and is characterized by its outstanding chemical resistance, high thermal resistance and good fatigue strength.

Its superior qualities and cost efficiency makes it a popular material of choice over Polyethylene (PE) and Polyvinyl Chloride (PVC) in industrial uses and also commercial uses. Due to its excellent thermal stability, PP can be used successfully even at 1000C. It shows superior impact strength as compared with PVC. PP is normally available in grey color and its high rigidity makes visually pleasing pipe layouts possible and the lower coefficient expansion makes installation easier. It is generally available in three forms for use in

pipelines PP- Homopolymer (PP-H), PP-copolymer (PP-C) and PP Random Copolymer (PP-R). Other options in PP include fire retardant grades & electro-conductive grades. PP can also be UV stabilized by use of a stabilizer and can also be produced in black color. Various types of commercially available PP includes the following: PP- Homopolymer (PP-H): is produced by a continuous chain of polypropylene units which results in a high stiffness material. Advanced homopolymer types like beta nucleated PP, are widely used to make piping systems. PP- Block copolymer (PP-B): Produced by adding 4-15% ethylene to the polypropylene gives much improved impact strength and considerably lowers the brittle point such that it is well below normal service temperatures i.e. -15oC to -20oC. Material is available in natural & grey colors. PP Random Copolymer (PP-R): Random copolymer PP typically contains between 1 and 7 wt.-% of ethylene molecules and 99 to 93 wt.-% propylene molecules. The ethylene molecules are inserted randomly between the propylene molecules in the polymer chain. Random copolymer polypropylene is a clear, semi-crystalline polymer which exhibits high stiffness, better impact strength and good electrical insulation properties. PP Fire retardant (PPFR): PP is enhanced by additives to limit its oxygen index. Available in V0, V1 & V2 classifications. PP Electro-conductive (PP- Cond): Also another type enhanced PP, developed especially for use in antistatic piping system.

B. Features and Advantages of use vs. other materials Polypropylene combines all the required favorable properties for modern industrial pipeline constructions, including:

Excellent Chemical Resistance - Increases reliability and scope of use High Impact Strength - Better durability High Thermal Resistance - Less vulnerable to weathering High Stress Crack Resistance - Prevents inching growth of cracks Excellent Fusion Capabilities. - Ease of installation and movement Low density, Low weight - Quick installation and transportation Homogenous structure - Aesthetically superior pipelines Good elasticity - Reduces number of fittings & eases installation Non Toxic, Food Grade - Can be used in food and pharma industry Smooth Inner surface - Low frictional loss & deposition, increased flow Good Thermal insulation - Excellent for use in hot and cold water systems.

1: The above values are adapted from DIN 8077. They have to be adjusted by a reducing co-efficient for every application depending on media temperature, concentration and composition. Also, UV radiation is not assumed in these values. Values are determined using a creep curve with safety coefficient of 1.6 to 1.25. 2: Values stated are for standard PP-Homopolymer. However specialty grades of PP may have better features. 3: Values in brackets are valid at proof of longer testing periods >1 year for 1100C tests

Process of manufacture of Polypropylene pipes Most plastic pipe systems are made from thermoplastic materials. The production method is basically the same for all thermoplastics – it is a matter of melting the material, shaping and then cooling. Plastic pipes are normally produced by extrusion, whereas fittings are produced by injection or compression moulding. Extrusion: Pipes made from PP and other thermoplastics are usually manufactured by extrusion. The extrusion process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted by the mechanical energy generated by turning screws and by heaters arranged along the barrel. The molten polymer is then forced into a die which shapes the polymer into a pipe which hardens during cooling. An haul off unit pulls the pipe and to feed it to cutting machine at the end of production line where the manufacturer is free to decide whether to cut the pipe into lengths of any six, twelve or even fifty metres, etc. Highly flexible pipes can be made even longer when coiled on a reel. Moulding: Fittings such as elbows, junctions or T-pieces are usually produced by injection-moulding. In injection-moulding, the plastic material is fed from a hopper into the melting section of the injection-moulding machine. After melting, the material is transported forward by the screw and homogenised before being injected into the mould to form the shape of the desired product. In the cooling step, the plastic solidifies. Then the mould is opened and the product is ejected.

Application of PP Pipes and fittings Typical applications:

• Suction and exhaust pipelines. • Lined Pipings (Mild Steel + Polyproplene) , (FRP + Polypropylene) • Water, effluent , chemical transport

Techniques of joining Polypropylene Among the techniques used for welding of polypropylene – butt welding, socket welding and extrusion welding are more commercially popular due to the easy portability of the welding machinery. Butt Welding: This technique is used for welding pipes made from

PE, PP, PVDF etc. The pipes are mounted in the clamps of the butt fusion equipment and checked for initial alignment. The pipe ends are then planed to ensure that they are flat & square. The welding sequence begins when a flat heated plate is positioned between the two pipe ends. The pipes are pushed towards each other until they come into contact with the hot plate

and the pressure is increased to give good thermal contact. The pipe ends melt and the interface pressure forces the molten material outwards to form 'weld beads' at the outside and inside pipe surfaces; hence the term 'bead-up' stage. Then the pressure is reduced to a value sufficient only to maintain the pipe in contact with the hot plate. This allows the melt depth to increase without increasing the size of the weld beads. At the end of this 'heat soak' stage, the pipe ends are pulled away from the hot plate. The hot plate is removed, and the two molten pipe ends are pushed together at the same pressure as used during the initial bead-up stage. This causes further growth of the weld bead and is called the 'bead roll over' stage. The pressure is maintained until the weld is fully cooled and joint is ready. Socket Welding: The socket fusion technique is also used mainly for PP and PVDF for fabricating process and piping systems. The method involves the use of a socket type fitting and the operation process is generally manual for small sizes. The welding cycle consists of a heating phase and a cooling phase. In socket fusion welding, a socket mounted on a hot plate is used to heat the outside surface of the pipe being welded. On the opposite side of the hot plate, a spigot is used to heat the inside surface of the injection moulded fitting. Both the fitting and pipe are heated for a set ‘heating time’. When the heating time is complete, the heated pipe and fitting are removed from the socket and spigot, and the pipe is pushed inside the fitting, producing the weld. Depending on the pipe size, this process is carried out by hand (for sizes up to 50mm OD) or on a mechanical/hydraulic machine, similar to a butt fusion welding machine, (for sizes typically between 63mm and 160mm OD). Extrusion Welding: The process involves continuously extruding molten thermoplastic material into a weld preparation on the plastic component or structure which is being joined. The extrusion barrel on the extrusion gun is heated along its length, either by cartridge heaters or hot air. A thermoplastic rod or granule feedstock is fed into the rear of the extrusion barrel and the material is heated as it is drawn through the barrel by the rotating extruder screw. The ejected material is shaped to match the profile being welded, and defines the shape and size of the final weld. At the leading edge, hot air is used to ensure there is sufficient heat in the substrate material to form the weld. Typical welding speeds are 0.5-1.0 m/min. Extrusion welding is generally used to weld custom fabrications with sheet, nozzles etc. Other methods of welding include infrared, bead and crevice free, friction welding depending on the requirements of the application and ultimate use of the manufactured products.

Storage and Transportation of Polypropylene Pipes Storage & Handling

Storage and handling of pipes made from PP, PE have to follow general instructions as for thermoplastic pipes. a) Pipes can be stored telescopically by storing lower

dimension pipes inside larger pipes. b) Storage heights should not exceed 1 mtr where

pipes are being piled together. Pipes may be stored in wooden/metal rakes with proper insulation to avoid damage to pipe surface.

c) Unless the pipes have been stabilized for UV – pipes should not be stored under the sun to avoid damage due to radiation. UV-non-stabilized Sangir PP Homo and PP-FR in natural and grey color should therefore be stored inside covered warehouses.

d) Damages to the surface of the pipe due to dragging or from sharp objects in storage area should be avoided.

e) Fittings may be stored in separate pigeon hole drums to avoid mixing and exposure to dust/sunlight. f) Impact and Bending stresses should be avoided for extremely low temperature situations. Transportation a) Pipes may travel telescopically however they should be properly aligned parallel to each other. b) Care should be taken in extremely cold temperatures to avoid unnecessary bends or stresses during

loading. c) Material may be loaded into vehicles that have roper covering from sunlight and can hold the Pipes

compactly to avoid unnecessary friction and damage during transport. d) Larger & heavier pipes should be loaded at the bottom of the cargo then succeeded with lower sizes

on them. e) Coils may be transported telescopically but care should be taken in extreme temperatures.
