PVC pipes are used in many ways and commonly used for water transport for drinking purpose. It is also used as removal of waste products to drainage from the roof or grounds.
For Drinking Water
The PVC pipes are used for supply water with control pressure. The main purpose is to distribute the drinking water. The pipes are used for it are medium-size and the diameter is between 75 mm and 250 mm.
The pipes are used for irrigation have same geometrical and mechanical characteristics.
Soil and Waste
Pipes are also used for waste water disposal as there are no pressure required and it is used inside building. It has medium diameter of 160 mm makes it compact PVC.
Sewage and Underground Drainage
The pipes and fittings are used underground horizontally for collection and disposal of waste water. The diameter of pipes is between 160 mm and 630 mm.
Rainwater
There are also a above-ground rainwater products like gutter and downpipes are available between 50 mm and 160 mm. It is available in both domestic and industrial use. For this application pipes are designed to use outside.
Hot and Cold
The chlorinated polyvinyl chloride (CPVC) pipes and fittings handle both hot and cold water for heating water system installation. These pipes are hot water pressure resistance.
Other Applications
Cable Protection
This type of pipe is used to protect electric cable inside. There is may be corrugated or smooth and having diameter of maximum 25 mm. There is also a larger diameter pipes of 50-100 mm used for underground cable protection made with compact PVC.
Fittings
There are many types of pipes, fittings and valves are available with various diameter. There are many designs and connections are made with fittings. It has many varieties like straight pipes, bends, branches, tees, reducers, clips, brackets and many more. These can be joints with simply push-fit or with solvent cementing. This joint provide system with gaps and are easy to install.
Industrial Piping Application
PVC piping systems are used for long times for cooling water process, transport hazardous chemicals as the PVC is high corrosion resistance. It is highly suitable to transport toxic chemicals from one place to another. PVC pipes are economical beneficial, safe and has less maintenance.
Fire Sprinkler
The CPVC pipes are used in fire sprinkler. The fire sprinkler systems are installed in places like library, museum, theatre, office, hotel, high-rise buildings etc.

Manufacturers are known the difference between two blow moulding processes. It is quite difficult to understand the difference. Here we will explain the difference between injection blow moulding and extrusion blow moulding.
Let’s start with Extrusion Blow Moulding Process
Extrusion blow moulding is commonly used type of blow moulding. In this process the plastic is melted to its boiling temperature. The melted plastic is extruded into a hollow tube which is generally known as parison. After that the air is blown to plastic and inflated according to the mould. Then plastic is cool down and after sufficient cooled, the mould is opened and product is come out from mould.
The blow moulding products are used in Traffic safety products, Automotive Ducts, Stadium Seating and Chairs, Trays, Containers, Coolers, Reservoirs and Tanks, Stands, Floats, Toys and Sporting Goods, Panels and Doors, Household products and Watering Cans and many more. SMP is leading blow moulding machine manufacturer in India.
Now Injection Blow Moulding Process
Injection blow moulding is another type of blow moulding where polymer is injected into a core pin. After that the pin is rotate to blow moulding station and there it is inflated and cool down. This process is not so preferred and used only to manufacture particular items like syringes.
There are variety of products are made with injection blow moulding process like dropper bottles, jars, ovals-cylindrical and boston rounds, tablet and pill bottles and many more.
What is the difference?
The main difference between blow moulding and injection moulding is process used to make a product. There is two-dimensional product is made with extrusion blow moulding and there is three-dimensional product is manufacture with injection blow moulding process. The other difference is in the tool used in the processes.
The next difference is time taken to complete the process. The injection blow moulding process took less time than the extrusion blow moulding. The scrap or residue makes the difference between two processes. In the extrusion blow moulding process, the scrap is with flash and trimming where the other have no flash and trimming. There is also difference in part thickness of machine used in extrusion and injection blow moulding processes. The part thickness is depending on the how much material is stretched in the extrusion blow moulding and with the injection it is on the relationship between core and mold.
The extrusion blow moulding process is simple then the injection moulding process. It is also depending on the material used from poor to excellent. The styrene is commonly used in the process which is poor material. The PP and PC are balanced products where HDPE is suitable for extrusion process.
The materials like Styrene, PP, PC and HDPE are suitable for injection process.

The full form of CLC is Cellular Lightweight Concrete. It also known as foamed
concrete. CLC is mainly used in construction as it has many benefits than the regular concrete bricks.
This foamed concrete is concrete with Portland cement, fly ash, water, sand
and preformed foam with various proportions. CLC can be easily manufactured at construction site with the same machine moulds used for normal concrete.
The main characteristic of this foamed concrete is its self-compacting property
and the compaction is not required. It is easily flowing through pump to the
mould. This helps to pumped it to the maximum distance and height.
The structure of CLC (Cellular Lightweight Concrete)
The clc mainly contains fly ash, cement and foam.
Fly Ash: The fly ash is a waste product of thermal power plants. It is not easily disposed. Fly ash is mainly used as raw material in CLC which solves the problem of disposal and also it is cost effective. The use of fly ash in clc makes it eco-friendly.
Cement: It is a mixture of Portland Cement, cement-silica, lime-pozzolana, cement-pozzolana and lime-silica. These all have same cell structure and they can get from gas-forming chemicals of foaming agents at measured levels.
Cellular Lightweight Concrete Manufacturing
These bricks are manufactured with mixing of raw ingredients in the concrete mixer. Strength is depending on the material used and also the air pocket content.
The continues CLC is made with mixing of light mortar and preformed foam with pressure in special static mixer.
What is the density of CLC?
Density is measured in KG per m3. The density of concrete is 2400 kg/m3. The foamed concrete density is between 400 kg/m3 to 1800 kg/m3.
The CLC density, is increased by foam filling. The foam is generated by foam-generator. The fly ash in clc decreases the density but it not affects the overall structure and strength.
Cellular Lightweight Concrete (CLC) are made with different density for various purposes.
Lower Density (400-600 kg/m3): The lower density clc are used for thermal and sound insulations. This density resists the fire, termite and moisture. The CLC is used as an alternating of glass wood, wood wool and thermocol.
Medium Density (800-1000 kg/m3): These bricks are used to make pre-cast blocks which are used for non-load bearing brickwork. It can be manufactured according to design and need.
High Density (1200-1800 kg/m3): This is a structural grade density and used in load-bearing walls and also in the ceiling of low-rise structures. It is also used in formation of partitioning walls and manufacture of pre-cast blocks for load-bearing brickwork.
Benefits of CLC (Cellular Lightweight Concrete)
Lightweight – The CLC is lightweight and it helps in weight management of building material and craning work.
Fire Resistance – Air pockets in the CLC bricks make it fire resistance. The more density in the clc walls can withstand for hours in fire.
Thermal Insulation – The low density clc bricks are suitable for thermal insulation. It also supports structure.
Sound Absorption – It increases the acoustical insulation.
Eco-friendly – The fly ash is used in the clc.
Cost-Effective – As it is eco friendly and also the production cost is less than concrete block which saves the overall construction cost.
The CLC (Cellular Lightweight Concrete) are termite proof and also resist to freezing. You can make this in cement bricks machine.
Where it is used?
- It is suitable for thermal insulation as bricks and clocks than the flat roofs and non-loading walls.
- Low density bricks are used in old sewer pipes, wells, unused cellars and basements, storage tanks, tunnels and subways.
- The heat-insulated light wall panel are made with clc.
- It also manages to maintain acoustical balance of concrete.
- It is used in light heat resistant ceramic tiles.
- For soil water drainage.
- It prevents freezing in bridges.
- Used for perlite plaster and lightweight concrete.
Difference between Lightweight Concrete and Aerated Concrete?
Many have confusion between gas or aerated concrete. The bubbles in the aerated concrete are formed chemically by the reaction between aluminium powder, calcium hydro oxide and other alkaline.
There is a mixing of air-entraining agent with concrete in Aerated concrete. And the foam concrete is made with different technique.
Cellular lightweight concrete has various properties according to their use in different building projects in the world. It also prevents the air, water and noise pollution.
These bricks are more suitable as it has many properties like fire resistance, eco friendly and it is also a preferred material for contractors and architects.
