CE standard bellows expansion joint is developed according to the relevant standards of CE company in the United States. The main feature is that the material of the bellows is generally made of Corten steel or stainless steel. Corten steel is low-cost compared to austenitic stainless steel. It is mainly used in the flue gas duct system of thermal power plant boilers with low temperature. CE rectangular bellows expansion joints can also be used on other pipelines with similar working conditions.
EJMA is a world-wide standard for the application, design, manufacture and acceptance of bellows expansion joints. my country's standards for bellows expansion joints are basically the same. The main feature of this waveform is waveform optimization, good compensation performance of bellows per unit weight, suitable for stainless steel manufacturing, large compensation volume, and wide application. It is especially suitable for pipelines with high temperature or corrosion resistance requirements such as heat network and flue.
