Double Wall Tanks

•  We specialize in the manufacture and sale of large  double wall plastic tanks for chemical storage. 
• We equip each tank with the fittings (flanged, threaded or sanitary tri-clamp) that our customers specify.  We install them where the customer specifies.

• Double wall tanks provide safety in case of hazardous spills.
  
• HDPE (Polyethylene) double wall storage tanks are the most common type becasue they  work for most applications and are favorably priced.
• Polypropylene double wall tanks can handle up to 200 F. and special chemicals.
  
• PVDF (Kynar) tanks handle even higher temperatures.
  
• Dual Wall Poly Tanks provide built-in Secondary Containment.

• We make an extended range of double wall chemical storage tanks.  Most of our tanks of 5,000 gallons and below can be made from different kinds of resins including:
• High Density Polyethyelene (HDPE), from Polypropylene and from Polyvinylidene fluoride (PVDF).  The best known brand name for PVDF is Kynar.  The two most common reasons for choosing a particular resin other than polyethylene are the need for a higher continuous use temperature and compatibility with a particular chemical.  You can check the chemical compatibility of the chemical you are storing with our tank resins by clicking here.

• Polyethylene is the most common choice because it is compatible with a wide variety of chemicals and it is the least expensive choice.  The primary limitation of Polyethylene is the upper continuous use temperature of 130 degrees F.  Some of the most popular storage applications for polyethylene storage tanks are diesel exaust fluid tanks, ethylene glycol storage tanks and bleach storage tanks.

• Polypropylene is the next most popular selection.  It is often chosen when a continuous use temperature of up to 200 degrees F. is needed.  Polyprolylene is also compatible with some chemicals that do not play well with Polyethylene.  Polypropylene is an excellent choice for Sodium Hydroxide storage tanks.

• PVDF (KYNAR) is a great resin since in certain applications it has a continuous use temperature of nearly 300 degrees F.  PVDF has good chemical compatibility.  The limiting factor on PVDF for Double Wall Storage Tanks is that PVDF is expensive.  Consequently, PVDF is selected only when the storage application requires the special properties that PVDF brings.  The brand of PVDF we use is Kynar by Arkema.
