Doğalgaz boru hatlarında koruyucu kaplamalara olan gereksinim ve daha uzun ömür talebi sürekli artmaktadır. Kaplama-altlık arayüzey arası kirlikler, uygun olmayan yüzey hazırlama koşulları ve bunun yanında optimize edilmemiş kaplama proses parametreleri zorlu çalışma şartlarında kaplamanın kullanım ömrünü sınırlamaktadır. Bu makale çalışmasında farklı ortam koşullarında, toprak üstünde çalışan spiral kaynaklı çelik (X70M PSL2) doğalgaz borularının katodik korozyona karşı korunması amacıyla elektrostatik sprey tabancası ile uygulanan ergiterek bağlanan epoksi esaslı (FBE, fusion bonded epoxy) kaplamaların test sonuçları ve karakterizasyonu sunulmaktadır. Tek katmanlı FBE kaplamaların performansına etki eden birçok faktör arasında kaplama öncesi çelik ön yüzey hazırlıkları; kaplamanın performansını önemli ölçüde etkilemektedir. Yapılan deneysel çalışmalar, ilgili uluslararası test standartları ve şartnameler (CSA-Z245.20 seri 14) kapsamında kontrol edilmiş, kimyasal karakterizasyon yöntemleri (FTIR, SEM) ile analiz edilmiştir. Değerlendirme sonucunda FBE kaplamaların başarılı bir şekilde üretilebildiği ve farklı sıcaklık koşullarında katodik soyulma, yapışma testlerinden başarı ile geçtiği gözlemlenmiştir.

The need for protective coatings in natural gas pipelines and the demand for longer life is constantly increasing. Impurities between the coating and the substrate interface, unsuitable surface preparation conditions as well as unoptimized coating process parameters limit the service life of the coating under severe operating conditions. This article presents the test results and characterization of fused bonded epoxy based (FBE, fusion bonded epoxy) coatings applied with electrostatic spray gun to protect spiral welded steel (X70M PSL2) natural gas pipes working against soil under cathodic corrosion under different environmental conditions. Many factors affecting the performance of single-layer FBE coatings include pre-coating steel surface preparation; significantly affect the performance of the coating. Experimental studies were controlled in accordance with relevant international test standards and specifications (CSA-Z245.20 series 14) and analyzed by chemical characterization methods (FTIR, SEM). As a result of the evaluation, it has been observed that FBE coatings can be produced successfully and successfully passed cathodic peeling and adhesion tests under different temperature conditions.
