Abstract:

 Natural gas pipelines are usually divided into two main branches as transmission and distribution pipelines. Natural gas is usually distributed with polyethylene pipelines for domestic use. However, steel pipelines transmission pipelines are used to transport natural gas from one region to another. In the construction of natural gas steel network, it is sometimes necessary to build vertical or horizontal curves. In such cases, the curvature capacities of steel pipes are decisive. Besides, an important factor limiting this capacity is local buckling. To strengthen the supply security of the natural gas network in Istanbul, it has been planned to integrate each other the natural gas steel transmission pipelines on both sides of the Bosphorus. Considering the cross-section of the Bosphorus, only the curvature capacities and thicknesses of the pipes and the local buckling limits have been taken into consideration in the plan, which can be considered as a vertical curve case study. Considering the steel pipes used in the Istanbul natural gas network, it has been determined which diameter pipes have which curvature capacities and local buckling limit values. Depending on the obtained results, it has been concluded that 12 steel pipe made of X-52 steel material gives the most optimum solution.

 Doğal gaz boru hatları iletim ve dağıtım hattı olarak genellikle iki ana gruba ayrılmaktadır. Ancak doğal gazı bir bölgeden diğerine taşıyabilmek için ise çelik boru hatları iletim hatları kullanılmaktadır. Doğal gaz çelik şebeke inşasında bazen düşey veya yatay kurpların dönülmesi gerekebilmektedir. Böyle durumlarda çelik boruların eğrilik kapasiteleri belirleyici olmaktadır. Bunun yanında bu kapasiteyi sınırlayan önemli bir faktör de lokal burkulma durumudur. İstanbuldaki doğal gaz şebekesinin arz güvenliğini güçlendirmek için İstanbul Boğazının her iki yakasında bulunan doğal gaz çelik iletim hatlarının birbirine entegrasyonu planlanmaktadır. Boğazın en kesiti dikkate alındığında bir düşey kurp örnek çalışması olarak değerlendirilebilecek tasarımda sadece boruların eğrilik kapasiteleri, et kalınlıkları ve lokal burkulma sınırları göz önüne alınmıştır. İstanbul doğal gaz şebekesinde kullanılmakta olan çelik borular dikkate alınarak hangi çaptaki boruların hangi eğrilik kapasitelerine ve hangi lokal burkulma sınır değerlerine sahip olduğu tespit edilmiştir. Elde edilen sonuçlara göre X-52 çelik malzemeden üretilmiş 12 çelik borunun en optimum çözümü verdiği tespit edilmiştir.
