Engineering Reliable Piping Systems for India’s Future
SHRIJI was created to deliver durable, precision-extruded polymer piping systems that dealers, plumbers, and infrastructure contractors can stake their reputations on.
A Product Brand Backed by Deep Polymer Science
In a piping market flooded with substandard recycled blends, brittle walls, and leaky threads, SHRIJI stands for uncompromised material integrity. Every pipe, fitting, and conduit bearing the SHRIJI name is engineered from 100% virgin polymer resin, formulated to meet demanding Indian and international dimensional standards.
SHRIJI operates within the industrial ecosystem of SJ POLYMER, drawing upon more than 14 years of hands-on polymer extrusion expertise, testing protocol coordination, and tooling optimization. This strong technical foundation ensures that our products deliver predictable flow coefficients, high tensile load tolerance, and decades of leak-free service life.
Pioneering Practical Polymer Engineering
"Pipes are the hidden circulatory system of modern civilisation. When a pipe cracks or leaks behind a tiled wall or three metres underground, the failure cost is catastrophic. SHRIJI is engineered so that failure is never an option."
Founded under the vision of Sandeep Kumar Jha, an industry veteran with over 14 years of industrial polymer experience spanning extrusion technology, injection moulding, tooling design, and rigorous quality inspection. With academic grounding in plastics engineering (CIPET) and Lean Six Sigma methodologies, he established SJ POLYMER as a trusted polymer technical consultancy and inspection advisory.
Under his technical leadership, SHRIJI was launched to bring this deep understanding of polymer formulations, melt flow rates, and stress-crack resistance directly to the commercial piping marketplace.
Strict Technical Governance & Quality Assurance
How SHRIJI products are formulated, supervised, and delivered to ensure consistent engineering tolerances.
Dedicated Formulations
We specify exact compound masterbatches, thermal stabilizers, and processing aids to eliminate brittle chalking and ensure high impact resistance.
Selected Partner Facilities
SHRIJI products are developed and supplied under technical oversight by SJ POLYMER and produced through selected high-precision partner facilities equipped with automated gravimetric extrusion lines.
Hydrostatic Batch Testing
Every lot undergoes rigorous dimensional checks, wall thickness ultrasonic measurement, short-term burst testing, and flattening stress tests before dispatch.
Strategically Located in Bihar for Eastern India Dispatches
Headquartered in the vibrant industrial hub of Fathua (Patna district, Bihar), SHRIJI is ideally positioned to serve the expanding infrastructure and housing boom across Bihar, Jharkhand, Eastern Uttar Pradesh, and West Bengal.
Our regional warehousing and prompt dispatch fleet ensure rapid replenishment for local hardware retailers and timely phased shipments for major EPC project sites.
