JPI leader in corrosion and abrasion resistant rubber linings for more than three decades., JPI has been supplying the entire range of rubber and other elastomer linings for both standard and highly specialized process equipment.
JPI has, over the years, successfully executed numerous challenging projects for various process industries. A review of JPI's list of prestigious clients, the nature and size of jobs undertaken both in India and abroad - a number of which have been repeat orders - is testimony to the confidence reposed in JPI by clients.
Excellence in quality is one such thing, on which we have never compromised under any condition. We have employed a team of quality auditors, who are checking the quality of our products throughout the production process. They work round the clock and make use of the available resources to guarantee the absolute finesses of our Rubber Lined Equipment (Cold & Hot Vulcanizing Systems).
Every stage of production process passes through stringent quality checks in our well equipped quality control unit. Our range of products is tested on the basis of the following parameters:
- Resistance to temperature
- Resistance to chemicals
- Strength
- Resistance to acids/ alkaliDimensional accuracy
