Material Integrity That Eliminates Compliance Risk

Material Integrity That Eliminates Compliance Risk

A single tank failure triggers fines, cleanup costs, and operational downtime that damages your bottom line. CRMI chemical tanks are built using roto molding with HDPE or XLPE construction, delivering uniform wall thickness without weak weld points. HDPE tanks up to 750 gallons carry a 1.5 SG rating, while larger HDPE and all XLPE tanks reach 2.0 SG — storing liquids up to twice the density of water. This vetted construction method means no seam failures, no leak points, and no surprise compliance violations on your next inspection. Tank Vault curates these units specifically because the manufacturing process eliminates the failure modes that cost fleet managers thousands.

Choose the Right Material for Your Chemical Profile

Choose the Right Material for Your Chemical Profile

HDPE provides high impact resistance and a high melting point, making it a reliable choice for general chemical storage. XLPE delivers superior heat resistance, chemical resistance, stress cracking resistance, and low-temperature impact strength. When your operation handles aggressive chemicals or extreme temperature conditions, XLPE offers measurable corrosion resistance beyond standard HDPE. Both materials are vetted by Tank Vault for real-world performance — not just lab numbers. Select from sixteen capacity options between 500 and 3,000 gallons, with containment configurations available up to 2,000 gallons for applications requiring secondary containment.

Specific Gravity Ratings Matched to Your Storage Density

Specific Gravity Ratings Matched to Your Storage Density

Specific gravity determines how dense a liquid your tank can safely hold. A 1.5 SG rating means the tank stores liquid up to 1.5 times the density of water. CRMI HDPE tanks up to 750 gallons are rated at 1.5 SG, while HDPE tanks from 825 gallons and all XLPE tanks carry a 2.0 SG rating — handling liquids twice as dense as water. This matters because overloading a tank beyond its SG rating creates structural risk. Tank Vault lists these ratings upfront so you select the correct tank for your chemical density without guesswork. This curated approach protects your investment and your facility.

Verify Your Site Fit

Confirm these conditions before ordering to ensure proper installation and compliance.

  • Site has a flat, level concrete pad large enough for the selected tank size
  • Containment footprint accommodates up to 2,000-gallon tanks if containment option is selected
  • Stored chemical specific gravity does not exceed the selected tank material rating (1.5 SG for HDPE, 2.0 SG for HDPE HD and XLPE)

Custom Roto Molding Inc chemical storage tanks provide efficient chemical storage for commercial and industrial use. The chemical storage tanks range in size from 500 gallons to 3,000 gallons and are available in high density polyethylene (HDPE) or cross linked polyethylene (XLPE). 

*Chemical tanks with containment are available in sizes up to 2,000 gallons.

Tank Material:

  • HDPE – High Density Polyethylene is a thermoplastic polymer created from petroleum.  HDPE has a high impact resistance and melting point.
  • XLPE – Cross Linked Polyethylene offers superior heat and chemical resistance, stress cracking resistance and low temperature impact strength. Offers superior corrosion and chemical resistance than HDPE.

Specific Gravity:

Specific Gravity is an indicator of the density that can be stored in a tank. A 1.5 SG means the tank can store liquid up to 1.5 times as dense as water.

  • HDPE – 1.5 SG
  • HDPE HD – 2.0 SG 
  • XLPE – 2.0 SG

*Note: HDPE tank sizes up to 750 gallons have 1.5 SG; HDPE tank sizes 825 gallons and greater have 2.0 SG.


Tank Options:
  • With Containment: Adds a second open top tank with a larger diameter that provides secondary containment for the primary chemical tank.

Note: Chemical tanks with containment are not available for all tank sizes.

Chemical Tank Features:

  • Includes threaded lid with breather.
  • 2 inch NPT Polypro bottom fitting (option to upgrade to stainless fitting for harsher chemicals).

    Chemical Tank with Containment Dimensions (Diameter x Height in inches):

    When purchasing a chemical tank with containment, the containment is provided by a second open top tank. The primary chemical tank has a smaller diameter than the open top tank so that it can be stored inside the wider open top tank.

    The dimensions below represent the open top tank (total weight represents the weight of the primary chemical tank + the weight of the open top tank):

    • 500 Gallon: 48″ D x 94″ H open top containment; total weight 304 lbs.
    • 525 Gallon: 72″ D x 38″ H open top containment; total weight 190 lbs.
    • 550 Gallon: 60″ D x 60″ H open top containment; total weight 220 lbs.
