1. Functionality: Expansion joints (bellows or compensators) are designed to handle axial, lateral, and angular movements, misalignment, and vibration within piping systems.

2. Customization: Standard joints come with three convolutions. More convolutions can be customized to provide greater movement. Optional reinforcements like rings and outer shells are available for high pressure or vacuum performance.

3. Safety Controls: Tie rods and hinges are utilized to limit maximum/minimum movements or prevent movement in specific planes.

4. Lining Options: High-quality lining materials include PTFE and PFA to resist corrosive media.

Note: For expansion joint sizes larger than DN300, a stainless steel housing type is recommended for enhanced vacuum resistance.

Frequently Asked Questions
What are the primary functions of these expansion joints?
Expansion joints are designed to compensate for axial, lateral, and angular movements, as well as to absorb vibrations and correct misalignments in piping systems.
Can the number of convolutions be customized?
Yes. While the standard design includes three convolutions, additional convolutions can be added to provide a larger range of movement.
What lining materials are available for corrosive media?
We offer several high-performance lining materials, including PTFE, PFA, and composite options like EPDM+PTFE or SS304+PTFE.
Which standards do these joints comply with?
The products are manufactured according to HG/T 3985 and GB/T 15700 standards, with flange options following ASME B 16.5, DIN, and JIS.
What is recommended for large-sized joints (over DN300)?
For expansion joints larger than DN300, we recommend using a type with a stainless steel housing to ensure proper vacuum resistance and structural integrity.
What is the pressure rating for these expansion joints?
Standard pressure ranges include Class 150, PN10, and PN16, making them suitable for various industrial piping applications.
