| Plastic Storage Tanks are made ratings of the specific gravity a tank can hold. A tank with a rating of 1.5 specific gravity (SG) should not be put into service holding a liquid that weighs 1.8 SG. Our Double Wall Chemical Storage Tanks are rated at 1.9 SG or above. We can even make tanks with higher ratings, such as 2.2 SG, for specific applications. | |
| ... | The specific gravity of a liquid tells you how much more or less dense the liquid is than water. Water has a specific gravity of 1.00. A liquid that is more dense than water, has specific gravity is greater than 1. A liquid less dense than water has a specific gravity is less than 1. |
| To calculate the specific gravity of a liquid, take the weight of that liquid and divide it by the weight of water. The weight of water will vary slightly based on temperature and pressure but for our purposes you can figure it at 8.34 pounds per gallon. | |
| The specific gravity of Sodium Hydroxide varies based on the concentration and the temperature. The specific gravity of a 50% solution of Sodium Hydroxide at 68 degrees F. is 1.52. | |
