First Polyvinyl-Chloride is known as PVC. You can easily start a PVC pipe manufacturing business in small and medium scale basis. The PVC pipes are widely used in electrical, irrigation and construction industries. The materials like wood, paper and metal are replaced by PVC in many applications. PVC pipes are widely used as electrical conduits in both domestic as well as industrial use.
PVC pipes are widely used for water supply. It has many characteristics which are suitable for water supply. It is lightweight, low cost, easy installation, non-corrosiveness, high tensile strength to bear the high fluid pressure. PVC pipes are resistant to most of the chemicals and also have maximum electrical and heat insulation properties.
PVC Pipe Manufacturing – Indian Market
In India, the PVC pipe market is on the peak as the infrastructure growing high and high. PVC pipes are mainly used in construction and agriculture sector and the demand is become increasing in the nearest future. It is used for various purposes like water supply, spray irrigation, deep tube well schemes and also in land drainage.
The PVC slotted and corrugated pipes are widely used for drainage of water from the land where waterlogging is necessary. As the demand in rural water suppliers, for irrigation facilities, development in the construction industry and the expansion of electricity network in rural areas. Over 60% of the demand for PVC pipe is in up to 110 mm outer diameter.
How to register PVC pipe manufacturing Business and Licence?
To start PVC pipe manufacturing business, register first with the ROC. Obtain Trade Licence from Municipality. After that apply for Factory Licence according to your current state rules. Apply for Udyog Aadhar MSME online registration. Apply for VAT registration. Also, apply for ‘No Objection Certificate’ from the state’s Pollution Control Board. Obtain the BIS certification for Quality Control. Open a current bank account in a nationalized bank. Secure your brand by Trademark Registration. Apply for ISO certification.

What are the raw materials used for PVC Pipe Manufacturing?
For PVC Pipe manufacturing required raw materials are PVC resin, DOP, Stabilizers, Processing acids, Lubricants, Colours, Fillers. The electricity and water are also required.
PVC Pipe Manufacturing Process
- Extrusion
For manufacturing of PVC pipe, like other thermoplastics the PVC uncompounded resin, is not suitable for direct processing. For process and stability require to mix additives with PVC resin. These are some additives are used in the manufacturing process for rigid PVC pipes: DOP, DIOP, DBP, DOA, DEP.
Plasticizers – common plasticizer are DOP, DIOP, DBP, DOA, DEP, Reoplast, Paraplex etc.
Stabilizers – The common stabilizers are lead, barium, cadmium, tin, stearate etc.
Lubricants – Lubricants used are Buty-Stearate, Glycerol Moni-Stearate, Epoxidised Monoester of oleic acid, stearic acid etc.
Fillers – Fillers are used for producing a special quality product like calcined clay.
Before starting the process, the PVC resin is compounded with plasticizers, stabilizers, lubricants and fillers for improving the process and stability of the product. The ingredients and PVC resin are mixed in a high-speed mixer.
In the process, the compound resin is fed to the double screw extruder and there are the inserts and die are fitted for required diameter. After that, the PVC compounds are passed through a heated chamber and melted under the compression of screw and heat of the barrel. In the last, the marking is done at the time of extrusion.
Sizing
The pipes come from extruder are cooled in the sizing operation. There are two types of sizing are used. Pressure Sizing and Vacuum Sizing.
Traction
The next process after sizing is traction. The tube traction unit is required for continuous haulage of pipes being extruded by the extruder.
Cutting
The last process is cutting. There are two types of cutting techniques for PVC pipes are Manual and Automatic. Then the pipes are tested for ISI marks and ready for dispatch.
Now arrange the suitable vehicle for transport the PVC pipes to the distributors.
