Product Description

FRP/GRP/GFRP/Fiberglass/composite vessel/tank:

Fiberglass tanks offer reliability, longevity and corrosion resistance for the diverse storage and process needs for a wide range of industries. They are low maintenance and are ideal for acids, caustics, solvents and non-flammable corrosive fluids in plating, petroleum production, pharmaceutical, chemical, pulp and paper, wastewater treatment, and other industrial applications. They can be customized to suit various corrosive environments through the use of different types of resins, such as isothalic or vinyl ester, and are available with many optional features and accessories such as covers, legs, blending baffles, manways, skimming weirs, and other custom features to suit your equipment requirements.

In addition to straight fiberglass tanks,we can provide dual laminate tanks. Dual laminate tanks incorporate a thermoplastic lining in a fiberglass tank to act as the primary corrosion barrier when the corrosion resistance required exceeds the limits of fiberglass. These linings are available in polypropylene, PVDF or PVC. The fiberglass is then bonded to the lining and creates a secondary corrosion barrier. Dual laminate tanks are a low maintenance alternative to glass, rubber or brick lined tanks.

FRP/GRP/GFRP/Fiberglass/composite vessel/tank can be divided:

I. By shape:

Horizontal tank/vessel, vertical tank/vessel with flat bottom, vertical tank/vessel with conical bottom, vertical agitating tank/vessel with flat roof, open top vertical tank /vessel, alien tank/vessel

II. By manufacturing method:

Shop tank/vessel (within DN 4m), on site tank/vessel (DN 4m - 25m), including FRP tank/vessel combined with PVC, CPVC, PP, PE, PVDF, etc.

III. By application: 

Chemical storage, stress reaction kettle, scrubbing tower, spray tower, food fermentation, ultrapure water storage, transportation vessel for train and vehicle

Typical process flow of FRP vessel

 1. Design and confirm the drawings and calculation notes 

 2. Prepare the appropriate equipment and mold

3. Make the seamless liner with special spraying gun

4. Wind the structural layers with program computer

5. Hydrostatic test             
6. Package and delivery

Property Description

1.  The surface of resin-rich layer should be smooth and clean, without damage, whitening, delamination, foreign inclusion and exposed fiber. The convex-concave larger than 3mm in diameter and 0.5mm in depth (height) is not allowed; For the pressure vessel, the max. allowable air bubble is 4mm in diameter. Within the area of 1 m2, the air bubble within DN 4mm should be no more than 3, otherwise the repair should be given; the depth of crack should be no more than 0.2mm.  

2.  The outer surface should be smooth and even color without whitening. Fiberglass must be impregnated with resin. Foreign inclusion, exposed fiber, interlayer delamination, delamination and resin blister, etc. are prohibited.

3.  For the resin content, it should be more than 90% in resin-rich layer, more than 75±5% in middle layer, more than 35±5% in structural layer and more than 90% in outer layer.

4.  The taper angle at the inner wall of tank is no more than 1°.

5.  Under the loading condition, the allowable hoop strain should not exceed 0.1%.

6.  When the winding layers are wound at helical winding angel 80°, its tensile strength should be equal to or more than 15MPa.  

7.  Barcol hardness on proudct's surface should be no less than 40.

8.  Water absorption should be no more than 0.3%.

9.  Length tolerance (distance between the peaks of two ends) is 1%.

10.The tolerances of tower's straightness and installation verticality are both 1/1000mm tower's height.

11.The difference between the max. diameter and min. diameter from the same section of the shell should not exceed 0.5% of shell ID.

12.Verticality between flange surface and stub should be conformed to the following table:

Nominal DN of flange stub≤100<250<500<1000<1800<2500<3500<4000

13.Angle deviation of flange stub should be conformed to the following table:

Nominal DN of flange stub<250≥250
Allowable angle toleranceφ0.5°

14.If nominal diameter of pipe joint is no more than 50mm, it should be capable to bear the torque loading of 1360N·m without any damage; if more than 50mm, 2700N·m.

15.The pipe joint should be able to bear the following torque loadings without damage.

Pipe joint size(mm)20253240506580100150200
Torque loading (N·m)230270320350370390400430470520
