Abstract

Farklı standartlarda polietilen boruların elektrofüzyon kaynaklı birleştirmeleri -5oC ile +30oC sıcaklık aralığında yapılması önermektedir. Ancak iklim şartları düşünüldüğünde özellikle soğuk ülkelerde ve acil durumlarda belirtilenden daha düşük çevre sıcaklığında kaynak gerçekleştirildiğinde birleştirmenin tokluğu üzerinde detaylı bir çalışmaya ihtiyaç vardır. Bu amaçla orta yoğunluklu polietilen (PE80) borular elektrofüzyon kaynak yöntemi ile oda sıcaklığı, 0oC ve -30oC sıcaklıkta temin edildiği şekliyle birleştirilmiştir. Birleştirmelere izod darbe deneyi testi uygulanmış ve kırık yüzey incelemesi gerçekleştirilmiştir. Sonuç olarak birleştirmelerin darbe dayanımını birleştirme çevre sıcaklığından etkilendiği belirlenmiştir.

Abstract

Standards used in electrofusion welding of polyethylene(PE) pipes, recommends to be carried out at the temperature range between -5ºC and +30ºC. However, when climatic conditions considered especially in cold countries and emergency situations when the welding process performed at lower ambient temperatures than specified; we need a detailed study about toughness of the weldments. For this purpose, medium density (PE80) pipes were joined with electrofusion welding method at the various environment temperatures (room temperature, 0ºC and -30ºC) as recieved. The impact resistance of weldments were investigated by Izod impact test and fracture surface inspection was carried out. As a result, the weldments impact resistance was determined to be affected by the ambient temperature.
