Stainless steel corrugated expansion device advantage：

Any type of flange can be applied to a metal bellows expansion for bolting into the piping system. Forged steel and plate flanges are available for pressure and temperature grades from 2.5Mpa to 5.0Mpa and diameters from 75mm to 2000mm. Execution Excellence gets it done, North Korea Waterproof casing Flange expansion joint corrugated expansion joint supplier--Zhongyuan valve fittings customer service Key Knowledge Reminder: Special flanges, such as looping flanges or angular flanges, can range in size from 300mm to 1800mm. Flanges of any size can be customized.

Stainless steel corrugated expansion peculiarity：

The innovative stainless steel corrugated expansion joint is mainly used to compensate for axial displacement, and can also compensate for lateral displacement or axial and lateral composite displacement. It has the ability to compensate for angular displacement, but it is generally not used to compensate for angular displacement. Building bridges across borders with our trade services, Zhongyuan valve fittings reminds North Korea friends that this information is helpful for choosing Chinese products: The above data is atmospheric pressure of 1.0MPa. If there are special requirements for universal corrugated expansion joints, they can be made separately. Stainless steel corrugated expansion joint standard number: GB/T 12777-1999 (new standard GB/T 12777-2008).

1. Super austenitic special stainless steel.
