POLYETHYLEN PIPES

 LENGTH OF PIPE

HDPE pipes from F 20 up to 110 mm are  manufactured in coils with lenth from  50 up to 1000 m depending of the dimension . The pipes from F 125 mm up to 250 mm are manufactured in straight  pipes up to 13 m.

 COLOUR OF PIPES

 The PE pipes can be produce in different colour depending of the purpose of the pipe. For drinking water supply the pipes are blue. Gas pipe are yellow or black with yellow stripes.

 BENDING

 On  “cold” PE pipes can be bend on radius not less than 15D of the pipe.

 ADVANTAGES

 HDPE offer the follow advantages among other materials:

 ·        RESISTENCE OF COROSION

·        FLEXIBILITY

·        POSSIBILITY OF LONG LENGTH

·        LOW WEIGHT

·        HIGHT RESISTENCE OF CHEMICALS

·        QUICK AND SIMPLE JOINTING

·        HIGHT RESISTANCE OF ABRASION

·        RESISTANCE TO THE GROUND MOVEMENTS

·        RECYCLABLE MATERIAL

·        LONG LIFE EXPLOATATION (MORE THAN 50 YEARS)

 USAGE

 The usage of the poluethylen pipes is as following:

·       Irrigation and water supply system

·       Drain system for industrial and urban waste water

·       Tranfer of chemical aggressive fluids

·       System for gas distribution

·       Optical cable protection

 CHEMICAL CARACTERISTICS

HDPE pipes have excellent resistence of the most chemicals. They are not release an  unpleasant taste, odorous and colour to the water.All the contituents of PE grades which  we use for water pipes are food approval.

 INSTALATION AND CONNECTION

 The conection of pipes are on different ways as follow

·       mechanical fittings

·       elctrofusion

·       butt fusion welding                                    

 For instalation pipes are recommended to be laying in trench with minimal depth of 45 – 60 cm, and the jointing of pipe have to be done on environment temperature  of – 10 °  C up to 60° C .

MATERIAL
HDPE pipes are  manufactured  from PEHD garnulate ( PE *) and PE 100) which contains only stabiliser ( antyoxidant) and  masterbach, for UV protection pipe.

The specific weight of  the material is over 950  kg/m3

TECHNICAL CHARACTERISTIC

 The pipe are manufactured in following working pressure : 4 ;6; 10; 16; 10 and 25 bar. The working pressure are  - 30° C up to 60 ° C . On a reqest of customer can be produce pipe with working pressure up to 32 bar.

 STANDARD

Konti Hidroplast , HDPE pipes are manufactured according International standards ISO/DP 4427 , German  DIN 8074/8075 and British BS 6437; 1984 and BS 6730/1986 y.
