Description
TARIFNAME KOMPOZIT KONIK KEÇE Mevcut bulus, boru hatlarinin özellikle de boru tesisatini durdurmaksizin (suyun, petrolün, dogal gazin ve diger sivilarin ve gazlarin) boru hatlarinin kaynakli baglanti yerlerinde boru hatlarinin arizali bölgelerinin ve kaynakli baglanti hatalarinin onarilmasi için ayni zamanda boru hatti yapim asamasinda kaynakli baglantilarin onarilmasi ile ilgili cihazlara iliskindir. DESCRIPTION COMPOSITE CONICAL FELT The present invention allows pipelines, especially piping, without stopping (water, welded pipelines of oil, natural gas and other liquids and gases) In the joints, the faulty areas of the pipelines and welded joints At the same time, the pipeline is welded during the construction phase to repair the faults. pertains to devices involved in repairing connections.
Boru hatlarinin onarimi için, birbirine bagli iki parçadan olusan ve yan duvarin iç yüzeyi ile bir borunun dis yüzeyi arasinda bosluk birakilarak boru hatti arizali alani çevresinde monte edilen borularin onarimi için farkli cihazlar sertlestirilmis metodu kisaca "CST" olarak adlandirilmaktadir. For the repair of pipelines, consisting of two interconnected parts and inside the side wall Pipeline failure by leaving a gap between the surface of the pipe and the outer surface of a pipe. Different devices for the repair of pipes installed around the area hardened The method is called "CST" for short.
CST'in çesitli dezavantajlari vardir, bunlardan baslicalariz 1) bir sivi kompozit materyalin enjeksiyonu esnasinda olusabilecek hava kabarciklari nedeniyle garantili bir onarim kalitesi sunamayan özellikle bir kusur üzerinde metalin bosluga bastirilmasina ve boru hattinin açilmasina neden olan boru ve yan duvar arasindaki boslugun kompozit materyal ile düzensiz doldumlma riski; 2) su alti boru hatlarinin onarimi için verilen yöntemin uygulanmasini kisitlayan dis metal yan duvar yarilarinin su altindaki ark kaynak isleminin karmasikligi; 70.11 3) metal yan duvarin toprak korozyonuna karsi aktif korunmasinin gerekli olmasi; 4) nispeten düsük maliyetli materyal ve onarim yapisinin bilesenlerine ragmen, kurulum için organizasyonel ve teknik önlemlerin maliyetinin yüksek olmasi, genis kapsamli onarimin pahali olmasi. CST has several disadvantages, the main ones being 1) air that may be formed during the injection of a liquid composite material A defect in particular that cannot provide a guaranteed quality of repair due to blisters. which causes the metal on it to be pressed into the cavity and open the pipeline. The gap between the pipe and the sidewall is uneven with the composite material. risk of being filled; 2) the application of the given method for the repair of underwater pipelines. the underwater arc welding process of the restricting outer metal sidewall halves. complexity; 70.11 3) the need for active protection of the metal sidewall against soil corrosion to be; 4) relatively low cost materials and components of the repair structure Despite the high cost of organizational and technical measures for installation that extensive repairs are expensive.
Lokalize korozyon kusurlarina sahip, bu dezavantajlari olmayan borulari oiiarmak için bir polimerik keçe, bir yapiskan tabaka vasitasiyla birbirine baglanan birkaç boru tabakasindan olusmaktadir ve boru hattini çevresel olarak kaplamaktadir; buradaki keçe, paralel olarak yönlendirilen baglanti saftlari vasitasiyla birbirine uçlarindan baglanmis mafsalli birimler ile iki ayri önceden olusturulan dokümani). Ancak, bu onarim yapisinin diger önemli dezavantajlari da vardir. Bu yüzden, metal yan duvarin yoklugundan dolayi bu keçe, onarilmakta olan alani, kusursuz bir düzeye getirmeye izin vermemektedir, çünkü baslangiçta fiberglas keçeyi isitarak saglanan ve daha sonra sogutma nedeniyle büzülen ön gerilmenin fiberglas mukavemet gelisimi için keçenin altindaki kusurun delikten ilerlemesini durdurmasi yetersizdir. Bunun nedeni, fiberglasin elastiklik katsayisinin, çelik elastiklik katsayisindan en az yedi kat daha düsük olmasidir. Dahasi, dökme fiberglas yapinin yaklasik 160 °C sicakliga kadar isitilmasi saha ortaminda oldukça zordur. onarimi için bir keçe bilinmektedir; burada keçe, çevresel olarak dalgali bir profile sahip iki yarim keçe seklinde önceden olusturulmus kompozit materyalden yapilmis bir bandi ve bant ve boru hattina bakan pürüzsüz bir profili içermektedir. To manufacture pipes with localized corrosion defects that do not have these disadvantages A polymeric felt for it consists of the pipe layer and surrounds the pipeline circumferentially; where the felt is connected to each other by means of connecting shafts oriented in parallel. two separate preforms with articulated units connected at their ends document). However, this repair structure also has other important disadvantages. This Therefore, due to the absence of the metal sidewall, this felt covers the area being repaired, does not allow to bring it to a perfect level, because initially fiberglass pre-stress, which is provided by heating the felt and then shrinks due to cooling. For fiberglass strength development, the defect at the bottom of the felt is propagated through the hole. stopping is insufficient. This is because the coefficient of elasticity of fiberglass, steel It is at least seven times lower than the elasticity coefficient. Moreover, pouring Heating the fiberglass structure up to a temperature of approximately 160 °C in the field environment it is quite difficult. a felt for its repair is known; where the felt has a circumferentially wavy profile of preformed composite material in the form of two half-felts with It consists of a tape made of tape and a smooth profile facing the tape and pipeline.

The main disadvantage of such a felt is 200 000 hours as an elastic pad, i.e. It uses technical rubber with a service life of approximately 23 years. Main Russian norms and specifications for the construction, use and repair of lines 70.11 to comply, the useful life of the materials used for these purposes is less than 30 years. For the continuous repair of the main pipelines according to the patent document No. should not be considered as a tool.
