The selection factors

The choice of metal hoses for connection of piping or installation between the equipment is performed after determination of the optimum length. In addition to geometric data should take into account the aggressiveness of the transported medium, the internal working pressure, temperature, pulsation equipment, the possibility of hydraulic shock. It is necessary to provide a line DN, the nominal diameter, the length of the metal hose together with the endings, the type and brand of fittings. It is assumed that the proposed product is of great quality, it will be a long operation. And given the complexity of the installation site, the General security in the use of metal hoses in aggressive or explosive environments will be observed trouble-free operation.

To ensure that products do not bring consumer inconvenience or unexpected troubles, you should implement all rules of choice of the installation work and operation.


Steel AISI 316 in their chemical properties and composition may not correspond to transport of the working environment in which more habitually feels hermetic steel hose AISI 321. If the operating conditions are quite severe due to high pressure and temperature, the lifetime of metallic sleeves with internal steel bellows due to the mismatch between matched steel grade may be minimal. Well, if the stage visual inspection equipment flaw will be spotted at an early stage. Therefore, when choosing the metal hose, you should know how stable this product to the effects of diverse environments. This can be done by the table of chemical resistance of steels.

Table durability

Table durability, presented in graphical form, is a list of over seventy names of liquid, solid and gaseous media chemical effects of which on steel has five categories of resistance:

  • TC — boiling point,
  • 2 — the use of a sleeve is unacceptable,
  • 3 — high degree of rust, a small life,
  • 4 — satisfactory resistance of steel,
  • 5 — high resistance.

The use of the data that are presented in the table, will help to determine the likelihood of damage to the hose during operation, and thus there is a need to study it before you make an order to purchase or manufacture the required set metal sealed hoses.

To guarantee stable operation of metal hoses at critical locations of industrial facilities should seek help from professionals who have a great experience and can give comprehensive advice on all issues regarding the manufacture and operation of metal hoses.
