Jrain specializes in the professional engineering and on-site fabrication of Large Size Field Tanks, providing a high-performance solution for industrial storage and processing. By utilizing advanced mobile winding technology, we eliminate the logistical constraints associated with transporting massive structures, ensuring that large-scale fiberglass tanks and vessels are manufactured directly at the project site with precision and efficiency.
Our field manufacturing process is engineered to deliver mechanical properties identical to workshop-produced laminates. By customizing resins, fiberglass, and fillers to meet specific corrosive or abrasive service conditions, Jrain ensures maximum durability and compliance with global industrial standards, providing a cost-effective alternative for projects with difficult access or extreme size requirements.

| Evaluation Metric | Workshop-Built (Large) | Jrain Field-Built |
|---|---|---|
| Transport Cost | Extremely High (Oversized) | Minimal (Equipment only) |
| Logistics Risk | High (Road/Permit limits) | Low (On-site production) |
| Size Constraints | Limited by Road Width | Virtually Unlimited |
| Installation Time | Slow (Heavy lifting/rigging) | Integrated with Fabrication |
| Overall ROI | Lower (Due to logistics) | Higher (Optimized cost) |
No. Jrain utilizes high-precision mobile winding machines that ensure the mechanical properties of the laminates are identical to those produced in a controlled workshop environment.
Our manufacturing processes strictly adhere to ASME RTP-1, ASTM D3299, ASTM D4097, and BS EN 13121 standards to ensure global compliance and safety.
We select specific resins, fiberglass types, and specialized agents or fillers during the design phase to match the chemical and abrasive properties of the stored media.
The process includes the installation of all fittings (nozzles, ladders), a comprehensive hydrostatic test, and optional operational training for the customer's team.
Field fabrication overcomes size limits and difficult site access while significantly reducing transportation costs and simplifying coordination with other on-site contractors.
Yes, Jrain has extensive experience manufacturing large FRP tanks and vessels at both domestic and international project sites under various environmental conditions.
