After detection of these failures by non-destructive testing such as ultrasound or by magnetic flux, the remaining time must be evaluated by a probabilistic approach. This work consists in evaluating the remaining service life of corroded pipes by Weibull approach over a distance of 70km from the Gaz pipeline Hassi R¿Mle - Arzew. Inspection results showed peak corrosion depths with a rate of 10-30% of the thickness and two areas damaged by corrosion with a rate exceeding more than 70%. The different reliability parameters namely reliability function, failure function, failure rate, rated life from MATLAB computer code were also determined and discussed.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786206163657\"\u003e\u003ch3\u003e- Case of the GZ1 gas pipeline \"HassiR'Mel - Arzew\" -\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786206163657","offer_id":46771536920901,"sku":"9786206163657","price":43.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b32a1213-0ffa-4da6-8194-ef56a82e5a66.jpg?v=1769840085","url":"https:\/\/shop.autorenwelt.de\/products\/inspection-and-study-of-the-lifespan-of-buried-structures-using-the-weibull-approach-von-ali-houari","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
