Gas supply

APPLICATIONS

  • Polyethylene gas pipe lines

ADVANTAGES

  • Flexibility, resistant of hydraulic impacts, ability for higher working lengths
  • Corrosion and abrasive resistance
  • Absence of precipitated layer to cause to pressure losses
  • Prevent noise or vibration spreading due to material elasticity and sound absorption ability
  • Durability – over 50 years depending on exploitation conditions (temperature, pressure and kind of transported fluid)
  • Resistant to freezing
  • Appropriate for earthquake areas
  • Resistant to vagabond currents

Polythilene gas pipes

The colors of pipes for gas supply made of polyethylene type 100 or type 100RC are black with orange stripe or completely orange. Co-extrusion pipes made of polyethylene type 100 or type 100 RC are with orange inner and outer layers, middle layer is black.

MARKING

Each pipe has a marking containing: company name, standard, trade mark, material, standard dimension ratio, outer diameter in mm, wall thickness in mm, nominal pressure in bar, designation, date of production, length.

Example: НБИ-Габрово; БДС EN 1555-2; КДН; PE 100 RC; SDR17; 110x10 Co-Ex; PN 10; Gas; 25.06.2015; 48

 

TRANSPORT

Pipes could be transported by any kind of vehicle with no difficulties, providing that following conditions are observed:

STORING

Pipes are kept in storage premises or in the open air areas arranged in rows up to 1.5m high, so that to evade deforming of pipes under their own weight. They also should be kept away from direct sunlight, hot surfaces, open fire or heating devices.
