When choosing a rubber expansion joint, there are many factors to consider. The type of pressure and temperature that the joint is subjected to is vital. While it is possible to choose a rubber expansion joint that is suitable for food use, it is important to make sure that the one you choose is food safe.
A food safe rubber expansion joint can be used in a number of different applications. For example, it can be used in the production of bottled beverages and cans. Similarly, it can be used to make pipes in food preparation facilities. It is made of materials that are not harmful to the environment and are odorless and non-toxic. These joints can withstand pressures up to 25 kg.
Food safe rubber expansion joints are made from FDA-approved rubber. They have excellent oil-resistance and are suitable for use in food processing applications. They are also safe for use in the production of flour, oils, and juices.
NBR High Temperature – DOUBLE YELLOW
NBR High Temperature Double Yellow rubber expansion joints are ideal for use in applications where high temperature and high pressure are a concern. They are made from nitrile rubber and feature steel wire cord reinforcement and a chloroprene CR cover. They can handle temperatures up to 140°C and offer excellent resistance to water, oils and hydrocarbons. They also have good tensile strength and excellent flexural properties.
The production process for NBR is relatively straightforward, but small inconsistencies in the chemical structure or composition can compromise the product’s strength. While the actual manufacturing process is not complex, it does require several types of equipment and additives. The main components are a polymerization process, monomer recovery, and coagulation. Fortunately, the necessary apparatus is easily available.
UNISOURCE SERIES ED, Style HA
The UNISOURCE SERIES HA rubber expansion joint is a type of elastomeric expansion joint that is designed for use on thin wall duct systems. These expansion joints are made from rubber that https://evrproducts.com/products/rubber-duckbill-check-valves/wastop-backflow-valve/ is less than half the thickness of standard pressure piping. The standard circular type includes an integral rubber flange, while the rectangular type incorporates a rubber flange and square corners. These expansion joints are designed to eliminate the need for splices near the corners. They are rated for increased axial movement, and require a metallic backing ring.
The UNISOURCE SERIES 303 EPDM rubber expansion joint is manufactured from high-quality EPDM rubber and nylon tire cord reinforcing. The EPDM material offers superior temperature resistance and physical properties over Neoprene. It also features galvanized steel floating flanges that engage the rubber beaded end of the expansion joint. The flanges also rotate easily for ease of installation. This style of rubber expansion joint is particularly useful for isolating smaller diameter piping from vibration-producing mechanical equipment.
Metraflex Style ED
A Metraflex Style ED rubber expansion joint is made with a specialized, full-face design, which prevents stress transfer from the expansion joint to the flanges. It is also designed with integrated control rods to help prevent excessive movement. However, it is important to properly install the joint to prevent it from being damaged by debris, as these can work their way into the housing of the Metragator. Alternatively, a Metragator vault can be used to directly bury the joint.
The flexible design allows expansion joints to fit many areas, including tight spots. While they are often an afterthought in multimillion dollar piping systems, they are the ideal choice for systems that require high flexibility and a low-friction seal. They can handle a wide range of media, temperatures, and pressures.
Flexi-Spool
The Flexi-Spool rubber expansion joint is a great solution for a variety of flanged, spool-type applications. It is made from natural or synthetic elastomers and is reinforced with a nylon or metal internal ring. It comes in unfilled or filled arch designs and can handle a wide range of working pressure.
The Flexi-Spool rubber expansion joint is used in numerous applications, including in the food industry. It can withstand large deformations and bends, and has a high recovery rate. The control units are useful as a backup safety device in the event of an anchor failure.
