Introduction:

1. For flexible connection of inlet or outlet of various kinds of pumps and valves.
2. SUS304 for pipe body, carbon steel for flange and pole; Customized material can be made available upon request.
3. Working temperature range: -196C-450C; For beyond this temperature limit, please clarify when make an order.
4. Can reduce vibration and noise, absorb thermal displacement, little force acts on the equipment.

Features:

1) Balances and compensates to prevent displacement or vibrations in extreme temperatures, pressure, or thrust.
2) Used extensively in all facets of the high-tech steel industry as well as other industries.
3) Have good flexibility and handle extreme temperature and pressure well.
4) They can play an important role in hose reciprocating motion, thermal expansion absorption, vibration absorption and adjusting compound tube center.
5) Important connector for gas, oil and water with modern equipment pipeline systems and piping projects.
6) Axis direction compensate: 10 - 100mm.
7) Angle direction compensate: 10 - 40 degrees.
8) Work temperature: -20 - 450 degrees.
9) Length: 100 - 2, 000mm or custom request.
