China National Building Material (Group) Corporation (CNBM) large on-the-spot filament winding FRP tank adopted the large scale on-site vertical design and overall suit equipment and technology which were imported from U.S. TANK INETICS Company which reached the international advanced standard of 1990s. The large FRP container took heat-cured resin as its main component and glass-fiber as its reinforced-material, while adopted double filament mouth to screw-wind and circular-wind with excellent physical property and corrosion resistance, expedient installation and without the need to maintenance, flexible design and rational wall structure.

Specification of FRP Tanks:

Diameter: 4m-25m, Capacity: 100m3-6000m3

Appearance design: vertical storage tank, horizontal winding tank, transportation tank, reaction tank;

Uses: Hydrochloric acid tank, pressure tank, anti-corrosion tank, glass fiber reinforced plastic tank, soy sauce anti-corrosion tank, glass fiber reinforced plastic tank, soy sauce tank.

FRP tank: the use of resin as adhesive, glass fiber reinforced plastic fiber as reinforcing agent.

Physical characteristics: the proportion of glass steel is usually 1.8-2.1, 1/4-1/5, steel, cast iron and plastic than the strength are high. The coefficient of thermal expansion of glass steel and steel is roughly equal, and the heat transfer coefficient is only 0.5% of steel.

The  characteristics of FRP tanks:

1, light weight, high strength: relative density between 1.5 and 2.0, only carbon steel 1 / 4 to 1 / 5, but the tensile strength is close to or even more than carbon steel, and specific strength can compared with high-grade alloy steel.

2, good corrosion resistance: the atmosphere, water and the general concentration of acid, alkali, salt, and a variety of oils and solvents have better resistance.

3, excellent electrical properties: can be used to manufacture the insulator.

4, excellent thermal performance: the low thermal conductivity of glass steel, at room temperature for 1.25~1.67kJ/ (M - H - K), only the metal 1/100~1/1000, is an excellent thermal insulation material.

5, excellent technology: according to the shape of the product, technical requirements, the use of flexible selection of molding process; process is simple, can be a one-time molding, economic effect is outstanding.

Application range of FRP tanks :

Medium application:

1, hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid, organic acid, hydrofluoric acid, fluoride, saline, sewage etc.;

2, food grade (vinegar, soy sauce, water, etc.);

3, polyvinyl chloride (FRP/PVC), polypropylene (FRP/PP), etc..

Industry application of FRP Tanks

FRP tanks are widely used in chemical, petroleum, manufacturing: paper, food, electronics, pharmaceutical, packaging, transportation and other fields.

RFQ of FRP tanks:

Q: What is fiberglass composite?

A: Fiberglass composite is a laminate made from glass fibers or filaments and thermosetting resin. It is commonly known as RTRP, RTMP, FRP, GRP, GRE and GRV.

Q: Are fiberglass tanks fragile?

A: Due to the elastic nature of the resin which holds the clothlike glass fibers together, fiberglass is strong and flexible. FPI products meet the rigorous "Impact Test" requirements of the international standard e.g. BS, API, ...

Q: Are fiberglass tanks an 'off the shelf' item?

A: No. FPI's fiberglass pipes are bespoke products engineered to the highest international standards and specifications.
