Products Description

Tied Universal Metal Expansion Joint is made up of two bellows joined together by a central pipe and a system of tie rods able to withstand the thrust produced by the internal pressure.

Tied Universal Metal Expansion Joint is used to absorb lateral movements in all planes. In addition and with a special design and/or positioning of the tie rods system this type may be used to absorb some axial and angular movements.

The tie rods are provided in sets of two or more, equally distributed around the circumference of the expansion joint. When the Expansion Joint is supplied with 2 tie rods at 180 degrees, the expansion joint is free to deflect angularly and laterally. With three or more tie rods only lateral deflections are possible.

The amount of lateral deflection depends on the amount of angulation each bellows can absorb and the length or the central pipe. The amount of lateral deflection capability can be increased or decreased by simply changing the length of the spool pipe and the thermal expansion of the central pipe is taken by the bellows elements.

Tied Universal Metal Expansion Joint is also widely used in industries such as oil, electricity, and steel. In the process of oil extraction and transportation, it can withstand high pressure, high temperature, corrosion and other conditions, playing a role in compensating for pipeline deformation and reducing vibration. In the power industry, it can also be used as a pipeline connection and compensation component to ensure the stability and reliability of power transmission during the transmission of high-voltage electricity. In the steel industry, Tied Universal Metal Expansion Joint pipes are mainly used in pipeline systems for high-temperature and high-pressure gases and liquids.

Advantage

High strength and durability: Bellows are made of stainless steel material, so they have high strength and durability. They can be used in various harsh environments such as high temperature, high pressure, corrosion, etc., and are not easily damaged.

Easy to maintain and clean: The metal corrugated pipe is made of stainless steel and other materials, with a smooth surface that is easy to clean and maintain. After cleaning, it can effectively prevent the growth of bacteria and ensure the hygiene and safety of the pipeline system.

Environmental protection and safety: Compared with plastic and rubber hoses, it does not pollute the environment and does not release harmful substances, making it more environmentally friendly.

Good anti vibration and noise reduction effect: It can absorb the vibration and noise generated during pipeline operation, effectively reduce pipeline noise, and improve smooth and stable operation.
