Advantages and Disadvantages of Expansion Joint Rubber

Rubber expansion joints are molded to fit almost any size. They are also available in arch shapes. You may need extra liners but it is not necessary. They are available in a wide variety of hardness ranges and shapes. The following article will discuss the advantages and disadvantages of expansion joint rubber. You can learn how to avoid potential problems by choosing the right type. Also, you will discover why Metraloops are the best choice for plastic pipes.

Flexibility is a disadvantage of expansion joint rubber

When choosing between expansion joint rubber and metal, there are some important factors to consider. One important factor is the amount of pressure that can be applied to the joint. While metal expansion joints can withstand over 1,000 psi of pressure, rubber is limited to 250 psi. Another important factor is the relative stiffness of the materials. While metal expanders are more durable than rubber, their relative stiffness should be matched with the overall force of the load.

One of the common failure sites involves loose bolts. While most expansion joints have bolts that can be removed without tools, different manufacturers have different bolt tightening requirements, and it’s often necessary to re-tighten them once they’re installed.

Control rods prevent overextending or over-compressing

Control rods are designed to keep expansion joints from over-extending or over-compressing. They are attached to the internal or external hardware of an expansion joint and have a predetermined force. These rods can be made of various materials, including stainless steel, aluminum, or carbon steel.

When installed correctly, control rods prevent over-extending or over-compressing of an expansion joint rubber. ThisĀ Our site is an important safety feature of any expansion joint. The proper installation of control rods will prevent over-compression of an expansion joint, which may result in a rupture. During installation, the rods should be evenly spaced around the flange.

PTFE and FEP liners are available for spool arch joints

Spool Arch Type joints are available in a wide range of standard pipe sizes. These joints have PTFE or FEP liners to protect the pipe from corrosion. The liners cover all wetted surfaces of the tube, providing outstanding chemical resistance. These liners are fabricated as integral parts of the expansion joint during the manufacturing process. They also provide exceptional pressure resistance through special external retaining rings.

Spherical expansion joints have several advantages over metallic joints. They are less likely to accumulate sediment, create less pressure drop, and eliminate the need for gaskets between flanges. They can be installed on flat-face or raised-face flanges. They can handle a wide range of temperature and fluid pressures.

Metraloops are ideal for plastic pipe

Metraloop expansion joints are a type of no-thrust expansion joint that clamps to a pipe. They are ideal for piping systems that are subjected to lateral and vertical movement. They are more flexible than metal expansion joints, allowing them to compensate for pipe movement and compensate for settling.

These expansion joints are often designed to fit tight spaces. Most have a wide arch, which enables low-spring-rate operation. Low-spring-rate joints are best for plastic piping, because they require less force to compress. Standard spring rates, while fine for ductile iron or carbon steel piping, can cause cracking and failure in a plastic piping system.

711 Plus is a full face rubber expansion joint

Full face rubber expansion joints are used for large connections. Their advantages include high internal density, pressure resistance, noise reduction, and good elastic deformation effect. They are also non-toxic and cost-effective. They are easy to install and disassemble. In addition, they do not damage the pipe body parts.

Full face rubber expansion joints can be used indoors and outdoors for both pipe and equipment installations. They are flanged with ANSI, DIN, JIS, or BS Standards, and can be custom-made to meet specific customer requirements. They come with an anti-pull-off device and are available in various materials.
