BELLOWS FOR A
As per client request Belman has engineered and manufactured these very special Chamber Pipeline Bellows. They are installed in a pipeline that carries sulfur in a chemical plant in Europe.
The client turned to Belman for a special Piping Bellow design. To ensure that the sulfur media in their pipeline did not solidify, the client needed to keep the temperature of the medium at a sufficiently high level. A chamber design could solve this, which is why the client needed an experienced manufacturer that was able to design and produce the very special Chamber Pipeline Bellows for them.
BELMAN SOLUTION – Chamber Pipeline Bellows
The Expansion Joints – a pair of Chamber Pipeline Bellows – were designed completely from austenitic stainless steel (EN 1.4571 and EN 1.4404), due to the operating conditions. They were designed with the characteristic bellow around another bellow. Chamber Pipeline Bellows are used to make it possible to increase the temperature of the media and thus improve the flow. The Chamber Expansion Joint is a design where the Expansion Joint has another Expansion Joint around it, whereby a chamber is formed between the two. In this closed chamber a media is heated and flows through the chamber via an inlet and an outlet respectively. On its way through the Expansion Joint, the heating medium emits heat to the inner Expansion Joint. In this way, the media (in this case sulfur) that flows in the inner bellow maintains/increases the temperature, which in turn increases the fluidity of the medium, thereby preventing the sulfur from solidifying.
Belman – expertise on Jacketed Pipeline Bellows designs
Chamber Expansion Joints are also known as Jacketed Expansion Joints or Jacketed Pipeline Bellows. Chamber Pipeline Bellows are widely used in chemical plants as well as in many other applications. Due to the nature of the media in these industries, Chamber Expansion Joints are manufactured in all types of steel materials, including high-alloy steels. Usually, the material is determined by the temperature as well as the type and consistency of the medium. If the medium is very corrosive, high-alloy materials are often used. The surroundings of the Expansion Joint may also influence the choice of material.
