Hdpe Pipe Joining Methods

Polyethylene pipes or HDPE Electrofusion fittings - 

HDPE Spigot Fittings are connected with each other by melting or mechanical fittings. 

External to the tubes made of other materials than polyethylene squeeze fittings,

flanges or other purpose-built can be combined with transition adapter. 

Connection fittings according to the convenience is the place to be used. 


Two methods are used for fusion welding by means of: 

Electrofusion (EF) Welding 

Butt Fusion Welding 


Electro Fusion Welding

Electrofusion welding process principle, Electrofusion Welding Machine and to be joined together of the parts which socket is in the copper wire to give electricity by heating both parts from the outside of a certain portion by melting together the fusion is to make. Electrofusion welding method 20 mm to 1200 mm diameter pipe can be welded. Electrofusion welding method is carried out in accordance with DVS 2207. 


Butt Fusion Welding

Butt welding method for welding of polyethylene pipes and fittings is currently the most widely used welding method. 

Coupling butt welding method, a butt welding the ends of the tube to be welded using heating plate

both ends with a certain pressure under heat by pushing toward each other is the process of fusion welding. 

Butt welding method of joining pipes with diameters up to 1200 mm can be welded. 

Butt weld bonding method is carried out in accordance with DVS 2207. 


BUTT FUSION WELDING and ELECTRO FUSION WELDING METHODS COMPARISON OF WELDING

Both sources by licensed welders and DVS 2207 is made in accordance with the method of butt welding and electrofusion welding is not no quality difference. From the labor resources in the right place in order to get the best results, you need to be sure that the correct method is used. 

The location of the source in terms of seeing butt welding method of welding, electro fusion welding method is advantageous compared to. The floor will fit in high places or places of welding machines welding electrofusion welding is more advantageous where necessary. 

Ease of welding processes according to their degree of butt welding is more advantageous. 

Electrofusion welding method be the factors that determine the quality of the source is greater than supply (pipe ovality, 

electrical voltage and continuity, dimensional tolerances, etc.). therefore, a butt weld, electrofusion welding is an advantageous. 

Resource costs according to the terms of the electrofusion welding butt welding is more advantageous. 

After welding electrofusion welding is more advantageous in terms of image.
