About Plastic Tanks

Plastic tanks and water tanks store substances utilized in industrial processes, such as water, sewage, petroleum and chemicals. They are utilized in numerous industries, such as the agricultural, oil/gas, water, waste treatment, medical, scientific and pharmaceutical industries. Plastic tanks are formed using either a molding or a welding process. Plastic tank molding, including rotational, blow and injection molding, involves using a model shape to form the tank. Plastic tank welding is a process in which two pieces of heat-softened plastic are joined through the application of pressure. Examples of this process are hot air and extrusion welding. Plastic tanks differ in size and capacity, ranging from small tanks holding a few gallons to tanks exceeding 35 feet in length, with a storage capacity of 50,000 gallons or more. Common plastic tanks include water tanks, septic tanks, chemical tanks, storage tanks, fuel tanks and double wall tanks.

The structure of the plastic tank varies. Common tank shapes include cylindrical, square, rectangular, hexagonal and octagonal. The heads and bottoms of plastic tanks also differ, according to their functions. For example, conical bottom tanks, which resemble a funnel, allow tank contents to flow quickly to the bottom of the tank, promoting easy tank drainage. Possible head and bottom shapes of plastic tanks include angular, spherical and conical. Plastic tank orientations include vertical and horizontal styles. Tanks can vary shape and size, even within the same type of application; for example, water tanks can be cylindrical, square, or funnel-shaped, and can hold anywhere from a couple gallons of water to tens of thousands.

Storage tanks are formed from a wide variety of plastic materials. Polyethylene (PE), a light, chemically- resistant thermoplastic, is the most commonly used plastic resin. Polyethylene resins include linear high density (HDLPE), cross-linked high density (XLPE) and linear low density (LLDPE) resins. Polypropylene (PP) is a light, durable thermoplastic that is denser, stiffer and stronger than polyethylene and has a high melting point. Polyvinyl chloride (PVC) is a durable, transparent thermoplastic that is resistant to non-essential oils but cannot be exposed to some solvents. Polyvinylidene fluoride (PVDF) is a durable thermoplastic that has high resistance to chemicals and abrasion.

Plastic tanks have several advantages over the traditional steel tanks. Their seamless construction provides them with greater impact strength and superior resistance to rust, corrosion and fuel additives. These virtually indestructible tanks have a longer lifespan than steel tanks, which can fracture and leak. Plastic tanks can easily be molded to fit tank compartments, unlike metal tanks, and are simple to install. This characteristic provides savings in size, weight and cost. Plastic tanks also cost less overall than steel tanks.

Types of Plastic Tanks

• Clarifier are tanks in which sediment and other precipitate settle.
  
• Double wall tanks provide superior protection against spillage of hazardous chemicals. Double wall tanks are used especially in high-pressure applications.
  
• Dual laminate tanks are tanks in which a thermoplastic lining – consisting of resins, such as polypropylene, polyvinyl chloride and polyvinylidene fluoride – is bonded to a fiberglass structure for reinforcement.
  
• FRP (fiberglass-reinforced plastic) tanks are manufactured from a combination of resin and glass and are rust-proof and long-lasting. FRP tanks formed from FDA-accepted raw materials are acceptable for potable (fit to drink) water.
  
• Plastic water tanks are used as primary or secondary storage for drinking water, water reserves and fire safety. The use of plastic water tanks is increasing, as the availability of drinking water to the consumer is decreasing.
  
• Poly, or polyethylene (PE), tanks are more durable, provide more chemical and corrosion resistance, require less maintenance and cost less than comparable steel and fiberglass tanks. Poly tanks are used in the water treatment and chemical processing industries for such hazardous fluids as sodium hypochlorite, sulfuric acid, caustic soda and hydrochloric acid.
  
• Polypropylene (PP) tanks provide excellent chemical and corrosion resistance, have a wide operating temperature, high rigidity and good structural strength and can be easily fabricated and welded using hot air, extrusion and fusion equipment.  Polypropylene tanks are ideal for a variety of electroplating applications and are increasingly being used in the demanding environment of steel process plants.
  
• Septic tanks are on-site sewage treatment systems that store waste materials in a large plastic tank.
  
• Storage tanks are plastic containers used to store various substances in industrial settings.
  
• Water tanks are plastic storage containers designed to hold water.
