An Industry Producing Efficient FRP Tanks

FRP is Fibre Reinforced Plastics. It is a modern composite material. FRP is used in construction for chemical plant equipment like tanks and vessels. Chemical equipment whose range of size is less than a meter to 20 meters is fabricated which use FRP as material. The FRP Tank Manufacturers has emerged as an important part of the industry in the past couple of years.

FRP tanks are mainly used in chemical industry. In these chemical industries, there are some sectors where FRP tanks are used such as chloralkali manufacturers, fertilizers, wood pulp and paper, metal extraction, electroplating, brine, vinegar, food processing, and in air pollution control equipment. There are many types of FRP Tanks such as:

FRP Tank Manufacturers
Scrubbers:
Scrubbers are used to scrub the fluid. It comes in three types –

Dry media:
Dry media scrubber is basically a solid media which is present in the middle of the tank or vessel on a system. These media control the concentration of the pollutant in the incoming gas. These vessels have several designs.

Wet media:
Wet media scrubber pours the polluted fluid into a scrubbing solution. These tanks are constructed to more stringent criteria. The design for wet media scrubbers includes the internal support system, internal and external pressure, environmental loads etc.

Biological:
It is a typical storage tank. It has an inlet, an outlet, a vent, an access port, a drain, and a nozzle used for overflow.

Size:
The tanks which are smaller in size are designed easily by using small and cheap materials such as PVC. The tanks which are larger in size are generally limited by shipping constraints. There is a choice to make many tanks of small diameters to control the storage of chemical and air pollution.

Design Standards:
FRP tanks fall under the regulation of several groups

#1. Bs4994-87: It is to avoid the uncertainty. It is the property of per unit width, per unit mass of reinforcement.
#2. EN 13121: It is the European standard which replaces BS4994-87 and it is current now.
#3. ASME RTP-1: It is with RTP-1 specifications, the primary concerns are related to stress and strain like hoop stress, axial stress etc.
#4. SS245:1995: It is the Singapore standard which is current now.

Limitations: The limitations of Fibre Reinforced Plastics vessels are almost based on the application parameters which are used. The Fibreglass vessels are also able to degrade the long-term in the state of having no protection from something harmful to sunlight. This is how the FRP Tank Manufacturers are producing the FRP tanks and are being utilized in the industry.
