An expansion joint is a type of connection that holds parts together

An expansion joint is a type of connection that holds parts together. These joints are designed to safely absorb vibrations and temperature-induced expansion of building materials. They can also be used to allow for movement due to earthquakes and ground settlement. Several types of expansion joints are available. These are important building components and should be installed during the construction process.


X-FOAM expansion joints are flexible, closed-cell polypropylene joint solutions. These products are designed for a wide range of applications including isolation, contraction and expansion joints. They will make their industry debut at the World of Concrete show in Las Vegas in January 2022. They are extremely flexible and durable, and are compatible with most common sealants. They can also be easily cut and shaped.

X-FOAM expansion joints can be used in a variety of construction projects. These adhesive-backed foam expansion joints provide support and fill to concrete and brickwork. They are non-absorbent and non-staining and provide a long service life. These flexible and lightweight expansion joints can be used in both exterior and interior applications. They are ideal for use in decorative concrete applications.

Metal bellow

A metal bellow expansion joint is a mechanical connection that uses bellows to expand or contract. These types of expansion joints are manufactured with the latest technology and by skilled engineers. The result is a high-performance expansion joint that has a long life and a high fatigue resistance. For example, you may use these joints for fans and compressors.

These expansion joints are categorized into three basic types based on the way that find out they move. They are axial, lateral, and angular. Each type contains a metal bellow that acts like a spring and satisfies certain basic criteria.


Polypropylene expansion joints are a common choice for sewer pipes and have several advantages. They are easy to install and are very effective. They can be used for all kinds of networks, from simple to complex. To choose the right device, you need to calculate the pressure and length of the pipe network. A good manufacturer will produce different kinds of expansion joints to meet the requirements of different networks.

In addition to being inexpensive, thermal expansion joints help to extend the lifetime of pipelines. They also help to solve the problem of thermal deformation. They solve the problem by reducing the number of rigid nodes and properly positioned supports. The polypropylene pipe material has a coefficient of linear expansion, which is taken into account when calculating the length of the deformable section. The degree of elongation varies depending on the temperature and type of material used.

Closed-cell polypropylene

One type of polypropylene for expansion joints is closed-cell polyethylene (CCP). Closed-cell polyethylene is a great choice for high-end applications, and can be used in a wide variety of environments. Its unique features include a non-sticky surface and is fully compliant with ASTM standards D 1751 and D 8139. It is also available in a range of colors, from light to dark gray.

Another type of polypropylene used for expansion joints is Nomaflex, which is a semi-rigid, closed-cell polypropylene foam. It is similar in appearance to the old-fashioned asphalt saturated fibre expansion joint, but is more environmentally and worker-friendly. It also reduces the amount of material that enters the joint, extending its service life. It is also an excellent choice for use in commercial, industrial, and civil construction projects. Nomaflex has been used in a variety of applications, including driveways, sidewalks, streets, highways, and even airport runways.
