Description

Product Introduction
The Swivel Flange Expansion Joint, also known as the Slip-on Flange Metal Bellows, is a pipeline system used to transport non-contaminated liquids or gases. It consists of a series of flanges and metal bellows. This product is typically made from metals such as stainless steel. Its main function is to provide high flexibility and reliability within the pipeline system. The inner layer of the bellows is smooth, and the surface is corrosion-resistant, making fluid flow smoother. The elasticity and flexibility of the bellows allow for the absorption of high pressure during cooling and heating processes, and it is not subject to fatigue or breakage.

The Swivel Flange Expansion Joint is widely used in industries such as petroleum and natural gas, food and beverage, chemical, and pharmaceuticals. It can be used to transport liquids or gases such as chemicals, water, oil, gasoline, gas, and steam, while resisting high temperatures, pressure, and corrosive media.

The Slip-on Flange is a loosely-fitting flange. The flange can be made by flipping, direct turning, or additional welding of a circular ring. Its advantages are that it does not generate additional torque on the container or pipeline when the flange is deformed, making it easy to manufacture. It can be made from materials different from the container or pipeline, making it easy to save precious metals. The disadvantage is that the flange’s thickness is relatively large, making it suitable for containers or pipelines with brittle materials and low pressure.
