There are various aspects of quality control followed in our company. These aspects ensure that the plastic piping systems offered by us, are precise and work well in diverse conditions. Some of these aspects are system control, internal control, test and acceptance of incoming goods, in - process inspection and test, process control, final inspection and test, external control, and storage / packing / dispatch. Each one of these is briefed below:

System Control

All the processes and results of work operations have to be properly documented. This requires following:

Final Inspection and test

We follow following regulations for the quality control of potable water pipes system:

These guidelines and standards explain the least needs for the internal control. The conformity with the standards is verified via laboratory tests and internal audits, by independent institutes.

Internal Control

Internal control of quality includes that the all the tests are carried out different stages by skilled personnel, in innovative laboratory. Following tests are conducted:

All these internal quality control tests are properly documented and saved.   

In - Process Inspection and test

Before the commencement of manufacturing, entire data related to quality is by our quality assurance department. Also, pre-manufacture samples are tested by technicians on following parameters:

Process data recording and ultrasonic measurement in the segment of extrusion are the part of process control. Ultrasonic automatically measures & reports the deviations in the tolerance factor. This report is send to the cutting device of extrusion machine. This ensures that that the sizing plant automatically isolates the substandard product. Hence, only the high quality products are packed and stacked.

Final Inspection and Test

All the finalized products are inspected and tested by following time laps test procedures. Also, the results are properly documented. These tests determine the weakness of the production stage. Following the final inspections and tests carried out:

We manufacture a range of piping systems by using the processes of extrusion and injection moulding. This has assisted us in becoming the market leader in developing polypropylene supply systems. To meet our production targets, we have two factories, one at Jalandhar and second at Baddi, both in India. The two factories are designed and developed as per the industry guidelines, along with ensuring that these conform to the environment protection policy.

All our piping systems and their manufacturing processes are environment friendly. During the manufacturing process, we make sure that there are no types of pollutants developed as a by-product. Even if there are some by-products, then we ascertain that these are properly treated so that they do not harm the environment.

In addition, we also use environmentally friendly materials in the production process. To ensure their environmental compatibility, all the additives (colour pigments & stabilizers) present in it are duly tested in our own laboratory as well as in prestigious independent laboratories. Some of the important ecological advantages of our products are:

• PVC free
• The additive share of Nagory product is below 3%
• Free from heavy metals that are hazardous to health (e.g. Cu, pb, N)
• Longevity
• Recyclable
