    Marine stainless steel expansion joints, marine stainless steel wave expansion joints GB/T12522

    Produced by Yangzhou Feihang Ship Accessories Factory, Jiangsu, China: Marine stainless steel expansion joints/marine stainless steel compensators meet the following three requirements:

    AS300-5 GB/T12522 Marine stainless steel expansion joints, marine stainless steel wave expansion joints

    ① Thermal expansion and contraction, displacement changes caused by mechanical vibration, and unique displacement changes caused by ship deformation caused by wind and waves.
    ②High temperature resistance and seawater corrosion resistance.
    ③In order to ensure the safety of navigation, the expansion joint must have a high fatigue life.

     

    GB/T12522 Marine stainless steel expansion joint/ Marine stainless steel compensator Applicable parts:

     

    Pipeline systems such as steam, water, oil pipelines, exhaust pipelines, diesel exhaust pipelines, engine pump inlets and outlets.
    Because the space on ships and naval vessels is precious, the displacement compensation components such as diesel engine exhaust holes and engine pump inlets and outlets on steam, water, oil and flue pipes should be corrugated with compact structure, good sealing and easy installation. Expansion joint.

    GB/T12522 Marine Stainless Steel Expansion Joint/ Marine Stainless Steel Compensator Definition:
    Chinese name: Stainless steel wave expansion joint English name: Stainless steel waveform theinflation festival
    Definition: A device installed in the middle of the pipe (smoke and wind pipe) that can compensate for the thermal expansion and contraction in the length direction of the pipe and maintain the tightness of the pipe. To
    Since its application in the domestic market in the early 1980s, it has a history of more than 20 years. It has been widely used in petroleum, chemical, heating, shipbuilding, cement, metallurgy and other industrial fields.

    The marine bellows expansion joint is formed by directly connecting two flanges with a bellows, which is a new type of connecting pipe. Corrugated pipe is a kind of thin-walled pipe with corrugated outer surface. It is generally made of stainless steel and has high axial elasticity. This product has the advantages of large displacement compensation, vibration isolation, high pressure bearing capacity, low stiffness, long life, etc., and the structure and compensation methods have great flexibility. The bellows expansion joint can be regarded as an elastic element in the application. In order to release the thermal stress of thermal expansion and contraction, it is generally called expansion joint on equipment heat exchanger, and also called bellows on pipeline.

    Installation instruction of Expansion Joint

    In order to ensure that the product will not be damaged during installation and the use life ,we suggest that the following items shall be paid attention to during installation.

    1.Before finishing the installation, don’t dismantle the transportation-securing rod.

    2.The arrow direction on the expansion joint shall be the same as the flow direction of the medium. No allowance to install in the opposite direction.

    3.Dont allow the riggings against the bellows directly to avoid suffering damage.

    4.Dont allow the weld splatter to touch the unprotected bellows, Moist chlorine-free asbestos can be used as the protection sheath.

    5.Dont use wire brush and detergent containing chloride to clean the bellows.

    6.Dont force to turn the end of bellows to align with the bolt-hole. Generally the bellows can’t bear the torque.

    7.Before proper installation, no water pressure test or vacuumizing to All the guide brackets and securing brackets.

    8.Don’t use the pipe hanger as the guide bracket.

    9.The test pressure shall not exceed 1.5 times of expansion joint rated service pressure.

    10.If teat will be done before installation, don’t use securing bar to support pressure and thrust.

    11.The compensation of pip doesn’t exceed that of expansion joint.

    12.After finishing the installation and before pressure test upon the whole system, to dismantle all the transportation securin
