Product design for extreme environments. Temperature +1315 °C [2400 °F] Expansion Joints for a Nylon 6.6 Plant in the Far East

We are specialized in the design and manufacture of engineered Expansion Joints for high tech industries. Our Expansion Joints are used in harsh environments where extreme temperatures, highly corrosive conditions and severe movements are experienced.

Overcoming thermal challenges

This time we have been awarded an order for the engineering, design, manufacturing, testing and shipping of several Expansion Joints for temperatures of +1315 ºC [2400 ºF].

The client located in the Far East is a world leader manufacturer of adiponitrile.  Adiponitrile is a chemical used chiefly in the manufacture of Hexamethylene Diamine, which is used widely to prepare Nylon.

As a versatile thermoplastic, nylon 6,6 can be melted and shaped to serve many applications, from heat-resistant auto parts to consumer electronics and kitchen appliances. But nylon 6,6 pellets can also be melted and extruded as continuous fibers. Due to their high strength and flexibility, these fibers can be used for everything from pantyhose to tough automotive air bags and durable sportswear. 

Main mechanical design and constructive parameters of these Expansion Joints are:
