Mabhaudhi eMonel anopa simba risingaenzaniswi uye kusaita ngura uko zvibatiso zvakajairika zvinokundikana—pombi dzemvura yomugungwa, mavharuvhu egasi rinovava, magidhirodhi akawanda emugungwa. Takagadzira anopfuura zviuru gumi nezviviri zveMonel K-500 neMonel 400 mabhaudhi edzimba dzepombi dzinodzvinyirira kubva muna 2019. Imwe neimwe yakapona pakuedzwa kwemunyu-spray kupfuura maawa 3,000 pasina gomba. Izvo hazvisi zvekufungidzira kuita. Ndiko kuvimbika kwakasimbiswa mumunda pasi pemitoro chaiyo yecyclic, kuvhunduka kwemafuta, uye chloride-yakaremerwa mamiriro ekunze.
Mabhaudhi eMonel haasi "stainless-steel-plus" chete. Iwo nickel-copper alloys-kazhinji 67% nickel, 23% yemhangura, pamwe nediki asi zvakakosha zvekuwedzera zvealuminium uye titanium muK-500. Kuumbwa uku kunogadzira precipitate-yakaomeswa microstructures iyo inoramba kusagadzikana-kuora kutsemuka zviri nani pane 316 stainless kana duplex simbi. Mune imwe offshore client's subsea valve assembly, kuchinja kubva kuInconel 625 mabhaudhi kuenda kuMonel K-500 yakaderedza bhaudhi kutsiva frequency ne70% pamusoro pemwedzi gumi nemisere. Sei? Nekuti Monel inochengetedza goho riri pamusoro pe1,000 MPa ichiramba kukoromoka papH 2–12 uye tembiricha inosvika 480°C.
Asi mabhaudhi eMonel anoda kuremekedzwa—kwete kungoyemurwa. Mwero wavo wekushanda-kuomesera wakanyanyisa. Tepi imwechete isina kurongeka panguva yekucheka shinda inogona kutsemura chisina chinhu. Isu takaona vatengi vachirasikirwa nemabhechi ese nekuti vakashandisa yakajairwa HSS matepi pachinzvimbo checarbide maturusi ane rigid inotonhorera kuburitsa. Monel zvakare inoita kupisa zvisina kunaka. Pasina kunyatso kudzora kupisa panguva yekugadzira, annealing yemunharaunda inopfavisa midzi yeshinda-kucheka hupenyu hwekuneta nepakati. Ndosaka tichipisa ma blanks kusvika 120°C tisati tarukwa, shandisa cryogenic-yakatonhodzwa ekupedzisira zvigayo, uye simbisa kuomarara munzvimbo nhatu dzeradial pajeti rega rega. Hapana nzira yekudimbudzira inopona iyi alloy.
- Kusarudzwa kwezvinhu kunokosha kupfuura nhamba yegiredhi. Monel 400 inokodzera static kuratidzwa kwemvura yegungwa; Monel K-500 inowedzera kuomesa zera rekuchengetedza torque mune inotenderera pombi shafts.
- Thread geometry haisi sarudzo-inoshanda. Unified National Fine (UNF) shinda dzinopfuura dzakakasharara munzvimbo dzakanyanya-kuzunguzika nekugovera clamp load zvakanyanya zvakaenzana.
- Kupedzisa kwepamusoro kunokanganisa zvakananga kutanga kwecorrosion. Ra ≤ 0.4 μm inodzivirira micro-crevices apo chlorides inotarisa; electropolishing inoderedza passive-layer defects ne 92% maringe ne mechanical polishing chete.
Vamwe vanogona kupokana mabhaudhi eMonel anodhura zvakanyanya-kusvika ku4 × kupfuura A2-70 isina tsvina. Nekudaro, mutengo wakakwana wekuva muridzi unotaurira imwe nyaya. Mumwe weNorth Sea opareta akateedzera gumi nemana hydraulic manifold joints pamusoro pemwedzi makumi maviri nemana. Nemabhaudhi asina tsvina, vakaita gumi nemapfumbamwe kuvharwa zvisina kurongwa kwekutsiva bhaudhi uye kugadzirisa gasket. Nemabhaudhi eMonel K-500, vakamhanya mwedzi makumi maviri nemiviri vasina kana kubvinza. Mari yebasa, nguva yekudzikira, uye yekuchengetedza yakaderedzwa nemadhora mazana maviri nemakumi maviri nenomwe pagore. Corrosion resistance haisi chinhu. Yakadzoserwa kuchengetedza-uye njodzi yakamisikidzwa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. michina Monel mabhaudhi anoshandisa ISO 9001-yakasimbiswa CNC nzvimbo ine chaiyo-nguva yekupisa muripo. Isu tinopa AMS 4675-yakasimbiswa mabheti, simbisa kuyerera kwezviyo tisati tagadzira, uye ita ultrasonic ongororo pabatch yega yega kuti tione subsurface inclusions. Maitiro edu anosanganisira mhinduro annealing pa 980 ° C ± 5 ° C, kukurumidza kudzima mvura, uye kuchembera pa650 ° C kwemaawa gumi nematanhatu-yakanyatso paASTM B564. Yese bhaudhi inotakura kuzere kuteedzera: nhamba yekupisa, tensile test report, intergranular corrosion test (ASTM G28A), uye dimensional CMM data yakachengetwa kwemakore gumi. Paunenge uchida mabhaudhi eMonel anobata torque mushure me50,000 kutenderera kutenderera mu95 ° C brine - hatifembere. Isu tinoyera, tinosimbisa, uye tinovimbisa.
Tichitarisa kumberi, mabhaudhi eMonel ari kubuda kupfuura kusungirira. Isu tave kuisa majeji ekuyedza mutsika Monel 400 bolt shanks yechokwadi-nguva preload yekutarisa mune dzakakosha pombi nheyo. Madhizaini echizvarwa chinotevera anobatanidza madiki-matanho ekuunza inline lubricant panguva yekushanda-kuwedzera nguva dzesevhisi mumashandisi ari kure enzvimbo yemafuta. Ramangwana harisi remabhaudhi akasimba eMonel. Iri nezve akangwara-akagadzirwa aine chinangwa, akasimbiswa nedata, uye akavakwa uko kukundikana isiri sarudzo. Kana chikumbiro chako chichida zero kukanganisa pakuvimbika, chemistry, kana kuenderana, monel bolts haisiriyo sarudzo yako yakanaka. Ndivo vega sarudzo yako.
