EXPANSION JOINTS AND  FLEXIBLE HOSES WITH ATEX CERTIFICATE.

Our manufacturer  is among the few companies of its sector that has obtained the European Certification ATEX.

This certification ensures the safety of the Expansion Joints and the Flexible Hoses used in explosion risk areas.

 

Pipes are subjected to expansions created by different temperatures, pressure, external movements and from pipes weight too. Where the values of strengths and the movements overcome the acceptable values, it is necessary the use of expansion joints that allow to absorb the different thermal expansion.
Some studious of engineering have declared that the employment of metallic expansion joints is preferred, because their flexibility absorbs movements in more directions with success, so that there is a considerable reduction of exercise costs (manpower).

Furthermore the losses of head and thermal dispersions are contained, with particular benefit to pipes having big diameter. The expansion joint, to be able to exploit its own functions, must be chosen and projected according to working conditions. To the aim, and to allow a careful study, the technical offices are at client disposal to examine the best solutions for every specific situation.

The expansion joints are classified according to the kind of expansion that they are able to absorb, as follows:

Axial - Universal - Hinged - Gimbal - Lateral - Spherical lateral - Pressure balanced axial and Pressure balanced.

All the expansion joints are manufactured according to:
ASME VIII div. 1e2 - EJMA - RINA - ISPESL - TUV.

THE BELLOW:

The bellow is the fundamental part of the expansion joint and it is obtained by hydraulic or mechanic trial from stainless steel or alloy steel having only one longitudinal welding.
A controlled behaviour produces a set of parallel metallic waves, that ensure maximum flexibility and reliability.
The system of calculation furnishes the stress analysis of the bellows, which allows to make calculations according to customers specifications.

THE MATERIAL:

The basic material to be used for the moulding of the bellows, have to meet the following characteristics:

  • efforts resistant.

  • corrosion resistant

  • weld ability

    For these  reasons, the material more used is the AISI 321 Stainless Steel ( max. temp. 800C )
    For superior values of temperature or corrosion it is used AISI 316 / 316L Stainless Steel, or alloy steels as Inconel, Incoloy, Hastoloy, Nickel and Monel.

     

Sizes available in DN 40 - DN 3600.
