Our Polypropylene tanks carry a limited three-year warranty from the date of manufacture. |
Should a defect in workmanship or material appear under normal use, service and maintenance within the warranty period Bailiff Enterprises, Inc. will, at its option, either supply a new, equivalent tank in replacement thereof or repair the original tank or refund a prorated portion of the purchase price. Bailiff Enterprises’ liability is limited to the tank itself and specifically excludes the cost of installation and/or removal or consequential damages. |
Operating beyond the temperature limits of a tank; hard piping without a flexible connector or operating at other than atmospheric pressure; or storing material that is chemically unsuitable for a tank are some specific examples of actions that void our warranty. Contact your chemical supplier for chemical resistance information. |
There are a few applications such as storage of sulfuric acid, bio-diesel, bleach and caustic soda that carry a one year warranty rather than our standard 3 year warranty. |
Fittings we install on a tank have a one-year warranty from the date of installation. Should a defect in workmanship or material appear under normal use, service and maintenance within the warranty period Bailiff Enterprises, Inc. will, at its option, either repair the original fitting or refund a prorated portion of the purchase price of the fitting. Bailiff Enterprises’ liability is limited to the fitting itself and specifically excludes consequential damages. |
Storing material that is chemically unsuitable for a gasket or fitting or allowing the weight of pipes or plumbing to rest on the installed fitting are some specific examples of actions that void our warranty. Improper installation that negatively impacts on the tank or the installed fittings will also void the warranty. |
Any optional additions to a double wall tank including valves, heat tracing, ultrasonic level sensors and other items carry only the warranty supplied by the manufacturer of that item. Bailiff offers no warranty beyond the manufacturer’s warranty and is not responsible for any consequential damages. |
The natural color of Polypropylene Resin is a translucent, milky white. That works very well in most cases because you can see the level of the stored liquid through the sidewall of the tank.
There are times when you may be better off by having a Polypropylene tank with opaque walls that keep out the light. This may be true if the liquid you are storing will be degraded by Ultra Violet light from the sun.
In addition to the translucent Natural color, we also offer Black Polypropylene tanks.
Black tanks are good options when the chemical does not degrade from higher heat. The black walls limit the UV rays that affect the inner part of the plastic tank wall. The Ultraviolet rays have a negative impact on Polypropylene so opaque walls will prolong the life of the tank. One downside of opaque tanks is the need for level gauges of some type to let you keep track of the fill level of the liquid in the tank.
While our Polypropylene Tanks are made with high quality materials and manufactured to exacting standards, improper handling and installation can damage them or their fittings. Follow the guidelines listed on this page to avoid problems. You may void your warranty if you do not handle and install your tanks properly. |
Handling: |
When tanks are delivered, they should be inspected for damage before the delivery is accepted. If problems of any kind are noted, they should be listed on the driver’s bill of lading and on the packing list. Contact us immediately so we can work with you to correct any problems as quickly as possible. |
Extreme care should be taken when unloading tanks from trucks. Tanks should be unloaded onto smooth surfaces that are free of rocks or other sharp objects that could cause damage. Be especially careful to guard against damage that can be caused by the blades on forklifts. Use a crane to lift large tanks from the truck. |
When tanks are being unloaded, moved or installed, damage to tank fittings must be avoided. Do not allow the weight of the tank to rest on any of the fittings. Do not roll the tank over any of its fittings. |
Installation: |
It is very important that tanks are installed on a surface that is smooth, firm and supports the tank completely. In almost all circumstances, a reinforced concrete base is the best solution. Even when a tank stand is used, the stand must be mounted on a solid base. Be sure to secure tanks and stands to guard against movement that could occur from wind, seismic activity, motion of contents or other causes. |
Consider the location of the installation and be sure you have enough room for maintenance activities. Since polyethylene tanks may contract or expand due to temperature changes, atmospheric conditions and the nature of the contents, proper planning is important regarding the space in which they are installed and the amount of material that is placed in them. |
You should consider the work activities that will take place in the vicinity of the tank and take precaution against accidental contact with the tank. Impact with the tank, especially at low temperatures, can cause tank failure. |
Certain tanks require support of the sides to avoid structural failure. Be aware of the properties of your tanks and the properties of the contents they will hold. |
Tanks are not designed to support the weight of machinery, equipment or any heavy load. Do not mount items like this on the top of the tank or on its fittings. |
If it is necessary for workers to enter the tank, great care should be taken to guard against asphyxiation or breathing of hazardous vapors and fumes. |
Fittings and Accessories: |
Be aware of the type of fittings used on your tank. Hand tighten plastic bulkhead fittings. If they are over-tightened, fittings may leak. |
It is important that fittings, valves, pipes and other accessories are fully supported. Fittings and tank attachments should not carry any weight. |
Since different materials expand and contract at different rates, expansion joints should be used to accommodate those differences and prevent damage. |
Care must be taken with the installation of accessories. Immersion heaters, for instance, must be installed so that they do not come in contact with the walls of the tank. Consult the documentation for the accessory for more detailed installation information. |
Tank Use: |
Use tanks only for the purpose for which they are created. Do not apply contents under pressure or create a vacuum unless the tank is specifically rated for that use. |
Make sure that the materials you store in the tank are appropriate for the properties of the tank, fittings, gaskets and accessories. |
Do not use the tank for storing liquids that are above or below the continuous use temperature for that tank. The maximum continuous use temperature for Polypropylene is 200 F.. |
Before Placing the Tank into Use: |
Test your installation by filling the tank with water before you put the unit into use. Verify the integrity of the tank and its fittings. |

| Bailiff Enterprises has been a leader in the industrial plastics business for more than 40 years. We operate a rotational molding plant and plastics fabrication shop just north of Houston, in Willis, Texas. |
| We specialize in large plastic tanks for chemical storage and custom rotational molding. Our double wall storage tank customers are usually looking for protection against the spill of hazardous chemicals. The secondary containment needs to have a minimum footprint to meet their needs. Our customers typically want flanged or threaded fittings in custom locations for automated or semi-automated plant use. |
| Our tanks can be outfitted with welded flanges up to 30″ in diameter, welded couplings up to 4″ and threaded bulkheads made from Polypropylene, PVC and Stainless Steel up to 4″ in diameter. Vents, level indicators, tank insulation and OSHA caged ladders are just a few of the optional items that can be added to the tanks we produce. |
| Bailiff Enterprises has tanks from common resins such as HDPE (High Density Polyethyelene) and is one of the few tank molders to produce tanks from Polypropylene and PVDF. We supply tanks from specialty resins because our customers rely on us to meet their needs for challenging applications. |
| We focus on customer satisfaction and we hope that we will soon be able to count you as one of those customers. |
The Linear Polyethylene Family is the most widely used group of plastics for rotational molding. These plastics are economical, tough, have wide chemical compatibility and are easily molded. Polyethylene is easily colored, and a long-term UV protection package is standard. HDLPE is not actually a correct term, but it provides a good shorthand for High Density Polyethylene that is from the linear family and not Cross-linked.
This polymer is an engineering plastic that is often selected due to its thermal properties. Polypropylene can handle continuous use temperatures up to 200 F. Polypropylene can be joined with thermoplastic welding. Unlike other plastic tanks, the inside surface of rotationally molded Polypropylene tanks may not be smooth. The integrity of the tank is not in doubt but there may be variation in thicknesses, especially on large tanks. Polypropylene can also be brittle at cold temperatures.
Kynar is specialty plastic that is used in high purity applications. It can handle temperatures up to 300 F. and is very resistant to most acids and bases. PVDF can be joined with thermoplastic welding.

There are times when it makes sense to make multi-layer parts. As an example, we can make HDPE tanks with an inner layer of PVDF. This gives a container with the chemical resistance of PVDF without the cost of a container made entirely of PVDF. We can make multi-layer parts with layers of each of the materials we mold. In addition to layering the different materials, we can also mold in a layer of linear polyethylene foam against a linear polyethylene wall. Contact us for details if you have an application that could benefit from multi-layer molding.
