Izinto zensimbi engenasiphene eziguquguqukayo ze-sleeve ezingangeni manzi ziyi-304,316L, iimpawu zayo eziphathekayo zizinzileyo, ukuguquguquka kwentsimbi nako kuhle kakhulu, into ebalulekileyo kukuba ukuxhathisa ukubola kungcono, kwindawo yendalo emanzi kunye nebandayo, okanye kwindawo yendalo. indawo enemithetho echasene ne-corrosion, ene-sleeve yensimbi engenamanzi engenamanzi, emva kwesisombululo esithile, inomsebenzi omhle kakhulu wokuchasana nomswakama kunye ne-anti-corrosion effect.
1.Ngaphantsi kwamanzi
Kwaye kwidama lokuhlanjululwa kwamanzi kwisityalo samanzi, insimbi engenasici eguquguqukayo engangeni manzi imikhono yentsimbi engenamanzi isetyenzisiweyo, oko kukuthi, ngenxa yokuba akulula ukugqwala, okanye izinga lomhlwa licotha.Kuyo yonke inkqubo yokwakhiwa kweprojekthi ethile, ukuba umbhobho wodonga awulungiswanga ngensimbi engenasici engenamanzi, ukwenzela ukuba udonga kunye nombhobho uthinte ngokukhawuleza, okokuqala, amandla odonga olubekwe phezu kombhobho lulula kakhulu. , okubangelwa ukuguqulwa okanye ukuphuka kombhobho, okwesibini, ukuvuza kombhobho kukhokelela ekukhululweni kwodonga kuya kubangela umonakalo omkhulu kumbhobho.Akukho nzima ukubona ukuba kubaluleke kangakanani ukusebenza kakuhle kwentsimbi engenamanzi engxoweni.
2.Emoyeni
Umphezulu weemveliso zetsimbi uya kusabela ngeoksijini emoyeni ukwenza ifilimu ye-oxide phezu komhlaba.Umahluko kukuba i-iron oxide eyenziwe kumphezulu we-carbon steel eqhelekileyo iya kuqhubeka i-oxidize, ibangela ukuba i-corrosion iqhubeke yanda kwaye ekugqibeleni yenza imingxuma.Umphezulu we-316L umbhobho odibeneyo wensimbi engenasici uya kusabela nge-oksijini, kodwa ngenxa yomxholo wayo ophezulu we-chromium, ukuxhathisa kwe-corrosion yensimbi engenasici kuxhomekeke kwi-chromium.Xa umxholo we-chromium wongeziweyo ufikelela kwi-10.5, ukuxhathisa kwe-atmospheric corrosion yensimbi kuphuculwe, kwaye umxholo we-chromium we-316L we-stainless steel welded pipe mkhulu kune-17. Isizathu kukuba xa insimbi ixutywe nge-chromium, uhlobo lwe-oxide yomhlabathi. ilungiselelwe ukufana nohlobo olwenziwe kwintsimbi esulungekileyo yechromium.Le oxide encanyathiselwe ngokuqinileyo yichromium-rich oxide ikhusela umphezulu kwi-oxidation eyongezelelweyo.Lo maleko weoksidi ubhityile kangangokuba ukukhazimla kwendalo komphezulu wentsimbi kunokubonwa ngawo.
Iimveliso ezinxulumeneyo
