Pamene mainjiniya afotokoza Maboti a Monel kwa ma valve a m'mphepete mwa nyanja, manifolds apansi pa nyanja, kapena makina opangira mankhwala otentha kwambiri, sakugula zomangira - akuteteza umphumphu wofunikira kwambiri. Kukana dzimbiri kokha sikokwanira. Kukhazikika kwa kutentha kumafunika. Kukana kwapang'onopang'ono pansi pa katundu wokhazikika. Kusasinthika kwa batch-to-batch mu mphamvu yolimba komanso kapangidwe ka tirigu ndizofunikira. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni monel bolts fakitale-osati kokha ogulitsa kapena malo ogulitsa ntchito - sizingakambirane.
Tawona ma projekiti ambiri akuchedwa ndi mabawuti omwe adadutsa kuyang'ana kowoneka koma adalephera kuyesa utsi wa mchere pa maola 1,200. Ena anasweka pa njinga yamoto yotentha pakati pa -60 ° C ndi + 450 ° C -osati chifukwa chakuti Monel alloy ndi yofooka, koma chifukwa chosagwirizana ndi kutentha kwa kutentha kapena kuzizira kosagwira ntchito bwino kumasiya kupanikizika kotsalira mpaka kutumizidwa kumunda. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timapanga ma bawuti a Monel 400 ndi Monel K-500 mnyumba, kuyambira ndi ASTM B164-certified bar stock, kenako ndikuyika njira yowongolera ndikuumitsa ukalamba pa AMS 5643. Magawo aliwonse amakumana ndi spark, ulusi wowongoka komanso kuwerengera kwathunthu. kuzindikira zolakwika za ultrasonic—osati zitsanzo chabe.
Zomwe zimasiyanitsa wokhoza monel bolts fakitale kuchokera kwa ogulitsa katundu? Zinthu zitatu: kuwongolera zitsulo, kuwongolera kwazithunzi, komanso kutsimikizira magwiridwe antchito. Choyamba, metallurgy. Kulimba kwa mvula kwa Monel K-500 kumadalira kulondola kwa faifi tambala-aluminiyamu-titaniyamu ndi mazenera otentha otentha. Timagwirizanitsa zinthu zopangira ndi ogulitsa ovomerezeka, timasunga kutentha kwathunthu mpaka nambala ya chipika cha ingot, ndikutsimikizira kuyankha kokalamba ndi makuponi olimba odulidwa kuchokera pa billet yomwe imagwiritsidwa ntchito popanga bawuti. Chachiwiri, chilango cha dimensional. Ulusi wa Class 3A pa bawuti ya Monel umafuna kupirira mokulirapo (± 0.0015') kuposa chitsulo chosapanga dzimbiri. Malo athu okhotakhota a 5-axis CNC amagwira ± 0.0008' pama diameter ovuta; Chitsimikizo cha CMM chimaphatikizapo cholakwika chotsogolera ulusi, kupatuka kwa ngodya yakumbali, ndi kutuluka - zonse zimanenedwa pa ASME B1.13M. Chachitatu, kutsimikizira ntchito. Sitimayima pa ma curve-tension curves. Kwa makasitomala mumafuta & gasi, timayesa kuyesa kofananira: kumizidwa kwa maola 72 mumadzi amadzimadzi a H₂S pa 120 ° C, kutsatiridwa ndi kutsitsa mpaka 90% ya mphamvu zokolola zomwe zidadziwika poyang'anira microslip kapena kupumula.
Ena angatsutse kuti zida za Monel zopangira zida sizingafanane ndi zinthu zomwe zidapangidwa. Iwo akulondola-kwa mabawuti. Koma ndichifukwa chake timapewa kutaya zomangira za Monel kwathunthu. M'malo mwake, timagwiritsa ntchito mipiringidzo yotentha kapena yokokedwa ndi madzi ozizira, kenaka timatembenuza molondola, kugudubuza ulusi (osati kudula), ndi electropolishing kuti tiwonjezere mafilimu. Kugubuduza ulusi kumapondereza kapangidwe ka tirigu pamwamba, ndikuwonjezera moyo wa kutopa mpaka 30% motsutsana ndi ulusi wodulidwa. Timatsimikizira izi ndikuyesa kutopa kwamitengo yozungulira pa ASTM E466, kupereka malipoti a S-N pama 10⁷ cycle. Kwa ma geometri omwe sali wamba, monga ma bolt a flange okhala ndi zingwe zophatikizika kapena zotchingira zozungulira, timapanga zida zanyumba, kuchotsa kuchedwa kwa gulu lachitatu ndikuwonetsetsa kuti GD&T ikutsatira kuyambira pachiyambi mpaka kupanga kwathunthu.
Kudalirika sikumapangidwa mu bolt ya Monel potumiza. Zimapangidwa mu ndondomekoyi chipu choyamba chisanawuluke. Izi zikutanthauza kuwunika kwazinthu zomwe zikubwera ndi osanthula a PMI-osati ma cert mphero. Imawunika pambuyo potembenuka movutikira, mutatha kutentha, mutatha kugudubuza ulusi, komanso mutatha kuyeretsa komaliza. Kuyang'anira komaliza kumaphatikizapo kuyesa kwa tinthu tating'ono tating'ono tating'onoting'ono, kutsimikizika kwa hydrogen embrittlement bake-out (pa ASTM F519), ndikuyika mu pepala la VCI lokhala ndi zizindikiro za chinyezi. Oda iliyonse imatumiza ndi lipoti lathunthu la mayeso: chemistry, makina, zotsatira za NDT, ndi mawonekedwe amtundu wosindikizidwa ndi gulu lathu la ISO 9001-certified QA. Timatumizira makasitomala kuchokera ku Houston kupita ku Hamburg ndi Singapore-osati kudzera mwa ma broker, koma kudzera mumgwirizano wachindunji. Pamene mabawuti anu a pampu akukumana ndi kuthamanga kwa 20,000 psi ndi nthunzi yodzaza ndi kloridi, "zabwino" sizomwe mungachite. Kulondola sikofunikira. Kutsatiridwa sikuyenera. Kukumana ndi Monel sizosankha. Sankhani a monel bolts fakitale yomwe imagwira bawuti iliyonse ngati gawo lothandizira moyo - chifukwa nthawi zambiri zimakhala choncho.
