Tank Choice
an image

When deciding on choosing a particular industrial polyethylene (PE or poly) processing TANK there are specific and general issues that must be identified to define the actual tank, the configuration of the tank and fittings, and let us not forget the cost. Cost will include the tank, the fittings and factory installation, and DELIVERY. Bulk poly storage tanks are large, and transporting these vessels can be very expensive. Deciding on the proper safe poly processing tank is dependent on the information given to the manufacturer. As always, the more accurately the issues are identified and addressed at the beginning of the process, will assure the proper HDLPE (or XLPE) safe tank will be installed, and at a lesser cost, in time and dollars, and longer life of the poly tank to the end-user. We will help you chose the perfect tank for your needs.

Strategy
an image

All of our tanks have been designed to the newest standards, and the only standard that applies to polyethylene tanks, ASTM D1998-06. However there are certain limitations and caveats which we can discuss with the customer to assure the proper vessel is designed and supplied.. Consult your SIERRA SALES representatives on material construction recommendations for your company's particular application We offer both high density linear polyethylene (HDLPE) and high density cross linked polyethylene (HDXLPE) tank resins to properly and correctly provide the storage and processing vessels that offer best in class performance, and at the most economical cost. We have five (5) different regionally located manufacturing plants, so we always attempt to assure freight and transport costs are held to a minimum.
Upon receiving your inquiry, we immediately go to work defining your project's specific tank requirements. Whether you're processing sulfuric acid, hydrochloric acid, sodium hypochlorite or just water, we define the entire vessel assembly in detail by line item. Now that we have completed study at Snyder Industries, Inc. Tank University, we are more able (and quicker) to choose the proper tank from any of our five strategically located plants, and fully customize the vessel for your project. From basic polyethylene bulk tank, to an engineered industrial masterpiece polyethylene vessel.

 

Rotationally Molded Polyethylene Tanks Offer These Advantages

Difference in resin. The advantages our HDLPE resin has over other rotomolded linear resins in tank applications Over XLPE
1. Over Linear, Medium and Low Density Polyethylene:
superior impact and stress-crack resistance

  • Improved weatherability
  • Broader chemical resistance
  • Lower notch sensitivity

2. Crosslink versus Linear:
"The most important advantage that crosslinkable polyethylene (XLPE) tanks have over linear polyethylene (LLDPE) tanks is that XLPE has a much higher molecular weight than LLDPE. In general, as the molecular weight of polyethylene increases, the environmental stress cracking resistance (ESCR), part impact strength, elongation, weathering, toughness, and tensile at elevated temperatures are improved."

This in fact is a true statement; however Snyder is using a TRUE HDLPE and not a LLDPE. In fact, during the molding cycle the density of resins changes and testing has shown us that we end up with a higher density with our HDLPE than with the CL200 XLPE.

We feel very confident that our studies and case histories can help us to determine the best resin for the application. Sii has always taken pride in our ability to get the full development of the physical properties of the resins which translate into chemical resistance and tank life.

Crosslinked vs. linear Advantages:
The most important advantage that crosslinkable polyethylene (XLPE) tanks have over linear polyethylene (LLDPE) tanks is that XLPE has a much higher molecular weight than LLDPE. IN GENERAL, as the molecular weight of polyethylene increases, the environmental stress cracking resistance (ESCR), part impact strength, elongation, weathering, toughness, and tensile at elevated temperatures are improved.
Wall thickness is not the only factor relevant to determining the strength of the tank. Proper material cure is more important than wall thickness in determining tank strength. Material cure is highly dependent upon the time of exposure to heat conducting through the tooling and the plastic material. Excessive exposure to high temperature will degrade the plastic material and cause a weak part. The ideal cure cycle is to reach the proper curing temperature as fast as possible, maintain that temperature for the correct period of time, and to cool the part and tooling at the proper rate of part temperature decrease. The superior Sii manufacturing process and oven capacity makes it possible to reach the proper cure temperature quickly and avoid the material degradation caused by slow oven temperature rise. Therefore, it is improper manufacturing technique to compensate for poor material cure with excessively thick tank walls.
