Performance characteristics of marine bellows expansion joints:

        High temperature resistance, seawater and chemical corrosion resistance, high flexibility, high fatigue life, compact structure, and reliable sealing. Since the space on ships and ships is precious, the displacement compensating components such as the exhaust hole of the diesel engine and the inlet and outlet of the engine pump on the steam, water, oil and flue pipelines should adopt waveforms with compact structure, good sealing performance and convenient installation. expansion joint.

Marine wave expansion joints must meet three requirements:

        Displacement changes caused by thermal expansion and cold contraction, mechanical vibrations, and unique displacement changes caused by ship hull deformation due to the influence of wind and waves.

        High temperature resistance, seawater corrosion resistance.

        In order to ensure the safety of navigation, it is necessary to ensure that the expansion joint has a high fatigue life.

Applicable parts of marine bellows expansion joints:

        Steam, water, oil pipeline, exhaust pipeline, diesel engine exhaust pipeline, pump inlet and outlet

Selection criteria for marine bellows expansion joints:

        CB1153 "Metal Wave Expansion Joint" is used in seawater, ballast, fire fighting, oil and steam piping systems.

        GB12522 "Stainless Steel Wave Expansion Joint" and GB1033 "Stainless Steel Wave Expansion Joint", the pressure is not more than 0.5Mpa, the temperature is not more than 550 ℃ exhaust piping system. http://www.yzjbwg.com
