EXPLANATION of the vertical columns of the previous type table

1. Type No = serial number in this selection list

4. Typen-Code = Type-Code

The type code usually contains 3 pairs composed of each two symbols (with a internal factory code). The 1st pair indicates the material of the inside of the hose. This determines the main characteristic of the hose. For faster identification, the inside ma terial of the hose is also indicated in its international code in Column 6 .
The nominal diameter is shown in front of the type code - separated by a hyphen (=DN) e.g. 150-N2.00.00 . Further DN are listed according to the SI (System International) in the following outline. Nevertheless, all intermediate diameters are also availabl e at short notice.
Standard diameters in clear width in mm.
Other widths are also available on request.

5. Temperat. = Constant temperature / and peak temperature in + °C or °F


These details are approximate. The coming together of several influences such as high mechanical stress and high chemical aggressiveness may reduce the temperature resistance threshold.


6. Material = international code of the masterial of the hose inner wall

7. Flam. = Inflammability category (based here on DIN 4102 only )

A1.... non-combustible, does not deform in fire ( e.g.: brick stone wall )
.A2... non-combustible, does deform in fire ( e.g.: steel structure )
..B1.. difficult to inflame
...B2. less difficult to inflame
....B3 inflammable

8. Mechanical = various mechanical properties

  1. Sealing tightness
  2. Mechanical resistance
  3. Rigidity
  4. Vacuum resistance
  5. Vibrations- + spark-resistance
  6. Bursting pressure
  7. (not operating pressure) in bar for DN 100 mm.
    conversion factor for other diameters :
    see page 18, column 7.
    Safety Regulations : ( based on DIN )
    for liquids :operating pressure x 2
    for liquids with gases :operating pressure x 3
    for gases :operating pressure x 3

 

1. 2. 3. 4. 5.
c



impervious to chemicals, resistant in the material group of Column 6
C



impervi. to chem., impervi. to almost all chem. attacks as made of Teflon
d



airtight for pneumatic conveying
D



impervious to liquids
p



microporous, however, sealed additionally with minerals
P



microporous for cooling during suction removal of hot gases

a


abrasion-resistant

A


highest abrasion resistanca

m


mechanically strong

M


very strong mechanically


R

Rigid : very rigid hose, nevertheless, narrow bending radius


r

n

normal: rigidity of the hose between soft and rigid


s

soft: soft hose



v

V
greater vacuum resistance




z vibration-resistant + resistant to alternate bending stress




f spark-resistant from the inside




F spark-resistant from the inside + outside
> > > > > " > " means that this characteristic may be added.


9. pH-Resist. = pH-resistance : resistance to acids and lyes (alkalis)

The pH value indicates the acidity or alkalinity (lye) of a medium. pH-value 7 is neutral. Values below this are acid, values above are alkali (lye). e.g. 1...14 means that this material is resistant to the most concentrated acids (1... ) and to the most concentrated alkalis ( ... 14 ).
Caution, the ph-velue gives no indication of chemical aggressiveness !

f foodable = suitable for use for food

10. Resist. = resistance to oil, fuels and solvents

o oil-resistant
f fuel-resistant and oil-resistant with no or slight swelling
F fuel-resistant and oil-resistant without any swelling
s solvent-resistant, except to compounds of chlorine, fluorine, bromide and iodine
S resistant to all solvents


11. OverHeat = emissions which endanger the environment if overheated.

The three-digit number before the dot is the temperature in + °C at which the material emits toxic gases ( however not below this temperature. Furthermore, below this temperature it may also be suitable for food in some cases. ) The toxic gas is indicated in the letters which follow the overheat threshold. With letters which follow the +, this indicates danger even below the overheat threshold.

hm heavy-metals : heavy metal compounds
fluor fluorine - halogen : fluorine gases + air humidity produce highly aggressive hydrofluoric acid
chlor chlorine - halogen : chlorine gases + air humidity produce hydrochloric acid; with heat dioxin !
chlor+o chlorine - halogen : as before, additional softeners poison ground water
cyan cyan - hydrogen gas : cyan hydrogen gas + air humidity produce toxic hydrogen cyanide
cdiox carbon dioxide gas : carbon hydrogen gas paralyses respiration, danger of suffocation indoors.


ENVIRONMENTAL QUALITY of the hoses ( for 11.)

No carcinogenic fibres (asbestos, quartz or finest glass fibres) are processed, also no carcinogenic powders. Allergenic fibres are supplied only with anti-allergenic impregnation. No dyes which contain heavy metals are used. Also no heavy metals as additives, as e.g. in the case of Hypalon. This is no longer supplied because of highly toxic lead vapours above 180°C / 350°F.
It has been substituted in the meantime by cheaper types of hoses.
Only special silicon rubbers are used which do not emit any formaldehyde gas. Silicon oils + silicon resins are never used !
The majority of hoses are free of chlorine or can be substitued by ones free of chlorine. PVC can be substituted with cheaper PE types which are free of softeners, these have only a minimum of chlorine additives ( 85 to 120 ppm = 0,0085 % to 0,0120 %)because difficult to inflame on the basis of DIN 4102 / B 1.
The hoses are manufactured in an energy-efficient manner. The hose constructions themselves save on materials, as it is almost always possible to achieve high quality with minium material input using composite techniques..
The high degree of compressability of the hoses allows a minimum of packaging which can also be recycled.
