Hoses & compressed air

Frequently asked questions — Hoses & compressed air

• How do I choose the correct internal diameter for a compressed air hose?

  The internal diameter of a flexible hose must be selected according to the flow rates required by your pneumatic installation. Rigorous sizing is necessary to guarantee the stability of the air flow and ensure the proper operation of your entire distribution network. It is essential to verify that these dimensional characteristics correspond precisely to the technical specifications of your existing systems in order to optimise the integration of components.
• Which technical criteria should be considered for the chemical resistance of a hose?

  The selection of a hose must incorporate the nature of the material forming its internal wall, a decisive factor for its chemical resistance. Users must ensure that the compatibility of the chosen materials is in line with the fluids conveyed and the sealing requirements specific to their installation. This rigorous technical approach helps guarantee the durability of your network and prevents any premature degradation of the flexible hose when faced with chemical constraints at the operating site.
• How can the choice of flexible hose be adapted to on-site mechanical constraints?

  The choice of a hose must imperatively take into account the actual conditions of use, particularly the ambient temperature as well as the mechanical or bending stresses encountered at the operating site. By evaluating these parameters, you ensure increased longevity for your installation. A selection adapted to the environment helps prevent the risks of premature wear and optimises the performance of the technical solutions supplied by our recognised manufacturers such as PREVOST, LACME, ALFAFLEX, CEDREY, ALGI or PRODIXAL.
• When should you turn to the compressed air range rather than watering or lubrication?

  The hoses and compressed air category is dedicated to technical solutions for pneumatic transmission requiring precise management of operating pressure and air flow rates. Although MecaIndus offers complementary ranges for watering, lubrication or spraying, the choice of a compressed air product must be based solely on the industrial criteria of your network. It is recommended to favour our specialised references to guarantee sealing and compliance with the mechanical requirements specific to compressed air distribution circuits.
