Large size field tanks have become a critical solution for industries requiring customized, large-scale storage and processing vessels. Jrain FRP, a leading manufacturer based in Hengshui, Hebei, China, offers advanced field manufacturing solutions that address the challenges of transporting oversized equipment. This article explores the product features, technical specifications, and applications of these tanks, while highlighting the company’s expertise and commitment to quality.
Large size field tanks are designed for scenarios where traditional transportation of pre-fabricated tanks is impractical. Jrain specializes in on-site manufacturing using customized winding machines and molds, ensuring the mechanical properties of the laminates match those produced in controlled workshop environments. This approach not only overcomes logistical challenges but also reduces costs and enhances project flexibility.
The process begins with mobilizing a dedicated team and appointing a project manager. Machinery and materials are transported to the site, where the winding machine and mold are assembled according to the tank’s diameter. Liners are created, and winding work is performed based on design specifications. After demolding, the tank is placed in its designated location, and fittings such as nozzles, ladders, and handrails are installed. A hydrostatic test ensures quality before handover to the customer.



Jrain’s field tanks are highly customizable, allowing the selection of different resins and fiberglass to suit specific service conditions. For instance, corrosive or abrasive liquids require specialized materials, while fillers and agents can be added to enhance durability. This adaptability ensures the tanks meet the unique demands of industries such as chemical processing, wastewater treatment, and oil and gas.
On-site manufacturing minimizes transportation costs and logistical complexities. By producing tanks at the project site, Jrain eliminates the need for oversized transport vehicles and reduces the risk of damage during transit. Additionally, the process allows for seamless coordination with other on-site contractors, streamlining project timelines.
Jrain adheres to stringent industry standards, including ASME RTP-1, ASTM D3299, ASTM D4097, and BS EN 13121. These standards ensure the tanks meet rigorous quality and safety requirements, making them suitable for global applications.
