Amapuleti ensimbi namashidi namakhoyili

Kunamuhla i-Merland emhlabeni, amapayipi ajwayelekile kakhulu cishe kuzo zonke izinhlelo zokusebenza ezihambisa noma yiluphi uhlobo oluwuketshezi noma lwe-gaseous. Lezi zinto eziwuketshezi noma ze-gaseous ziyageleza ohlelweni lwepayipi ngezingcindezi ezahlukahlukene namazinga okushisa. Ngakho-ke, amasistimu wepayipi ahlushwa izingcindezi ezedlulele ezikhiqizwa ingcindezi kanye nokushisa.

Ukuqina kwensimbi kungenye yezinzuzo ezinhle kakhulu zezinhlelo zepayipi. Kuqinile futhi kungamelana nezingcindezi, amazinga okushisa, ukushaqeka okusindayo, nokudlidliza. Iphinde ibe nokuguquguquka okuhlukile okunikezela ukunwetshwa okulula.

Ngale nzuzo, yonke ipayipi esebenzisa izimboni inethuba elihle lokukhulisa ukusebenza kahle kohlelo lwepayipi futhi yehlise isidingo sabo sokusebenza nesikhathi.

I-Alloy X yaziwa ngamandla ayo okushisa aphezulu kakhulu futhi ingamelana namazinga okushisa aze afike ku-2200¡ãf. I-alloy nayo ingahlelwa kalula ngezindlela zezincwadi nezizenzakalelayo ngokwakhiwa kanye nezakhiwo ze-welding. Ngaphezu kwalokho, i-Hastelloy X imelana nokugqwala, ukushisa kanye noxidation futhi ingamelana nokunciphisa noma ukungathathi hlangothi kanye ne-oxidation.

I-Alloy 317L inokuphikiswa okuhle kakhulu kokugqwala ngamakhemikhali ahlukahlukene. Imelana nokuhlaselwa ku-sulfuric acid, i-chlorine ye-acidic ne-phosphoric acid.

Zisetshenziselwa insiza yokushisa ephezulu, lapho kudingeka khona i-oxidation kanye ne-carburburation. Ngezakhiwo ezinhle kakhulu zokucindezela kwengcindezi, noma insiza yomkhumbi yengcindezi engenhla kwe-815¡Ãc, incoloy 800h noma incoloy 800ht kufanele isetshenziswe.

I-904L I-Steressless yensimbi ayifani nanoma iyiphi enye insimbi. Ngenxa yamanani angeziwe angeziwe we-chromium, i-molybdenum, i-nickel ne-zethusi, insimbi engu-904l ifaka ukumelana okuphezulu kokugqwala, ukugqwala kanye nama-acid.

Cishe ukungavikeki ku-chlorine ion ingcindezi yokugqwayiza ukuqhekeka. Ibonisa ukumelana okwanele kuma-organic acid afana ne-acetic, enobuntu ne-stearic. Ukumelana okuhle kakhulu emanzini ahlanzekile ahlanzekile asetshenziswa emasekeni asemqoka nasekokondari ezindabeni zenuzi ezicindezelwe.

I-Steel yensimbi esetshenzisiwe njengegama ngokwalo imisindo, yenziwa ngensimbi yangaphambi kwezobuciko. Ukwakheka kwenziwa endaweni elawulwayo ngaphakathi kwefektri bese kuthunyelwa endaweni yamakhasimende e-ASPOLD.

Ama-Flanges ayimpumputhe ukuhlukaniswa kokugcina kwesigaba se-flange. Zisetshenziswa njengezindela zokugcina zama-valves amapayipi noma amaphampu. Njengoba ama-flanges ayimpumputhe asetshenziswa njengezithiyo ngokumelene nokugeleza kwamanzi, ziyizingxenye eziphakeme kakhulu ze-flange systems.

Ama-Tees we-Welded eSocket akhiqizwa ngenxa ye-ASTM ASME B16.11 amazinga. Lawa mazinga enza kahle futhi anqume ukucindezela okufanele kwengcindezi kanye nezilinganiso zokushisa, ama-radiyudi kanye nezinto ezidingekayo zokukhiqizwa kwama-tees. Ngaphezu kwalokho, amazinga we-B16.11 avumelekile kuphela nge-carbon ne-alloy steel. I-selded ye-welded yeSocket ingakhiqizwa ngezigaba ezintathu zokucindezela okuyizo; I-Class 3000, isigaba 6000 kanye ne-Class 9000.

Ukwakheka kwepayipi kubaluleke kakhulu ngoba ukwakhiwa komkhumbi nezinye izimboni zasemanzini zidinga amapayipi amakhulu. Amapayipi Spools adala izinzuzo ezinhle ngoba anciphisa ukulinganiselwa kwesikhala esizeni.

I-Incoloy 800 N08800 Pipe Spools enezengezo ezifana ne-molybdenum Copper nitrogen kanye ne-silicon

I-Hastelloy B2 ivimbela ukwakheka kwe-carbide ye-carbide yokusanhlamvu endaweni ye-weld Heart athintekile zone, okwenza kube lulungele izinhlelo eziningi zenqubo yamakhemikhali esimweni se-as-welded. Indawo ethintekayo ye-Weld Ethintekile yehlisa indawo yemvula ye-carbides nezinye izigaba ukuqinisekisa ukumelana nokugqwala okufanayo.

Izidingo zeklayenti¡. Futhi singanikeza okususwayo kokusebenza okuqukethwe okuqukethwe okuqukethwe, kufaka phakathi amamojula wokusika amapayipi, ukubheja, ukuhlangana futhi

I-304 insimbi engagqwali inobuthakathaka obunye: Itholakala ekugculweni okuvela kwizixazululo ze-chloride noma ezindaweni zesawoti ezifana nogu.

Amapayipi angama-304 enziwe ngensimbi engama-304 engagqwali, impahla ejwayelekile futhi ethandwayo kuzinhlelo eziningi zezimboni ezidinga ukumelana nokugqwala kanye noximation. Lawa mapayipi amapayipi e-S30400 ahlanganiswe asebenzisa imishini ekhethekile nezinqubo, eziqinisekisa ukuthi zinembe kakhulu futhi zithembekile.

Ama-Tees nawo asetshenziselwa ukuguqulwa kwe-angle yokugeleza nokusatshalaliswa kwento egelezayo kungaba esiteshini esisodwa noma ngaphezulu. Tees ingahlukaniswa ngamaqembu amabili aphambili okuyi-butt welded tees kanye ne-socket i-Welded Tees. I-Butt Welded Tees isetshenziswa ukwenza ukusatshalaliswa kwe-perpendicular kokugeleza. Benza amagatsha angu-90¡Ã0¡Ã axhumano ngepayipi futhi asabalalise udaba oluzayo kusuka ku-mainline.

I-Alloy 400 iphansi ngamandla esimweni esiveziwe se-annealed pho simo, izisusa ezahlukahlukene zingasetshenziswa ukwandisa amandla.

I-Monel K-500 ihlanganisa ukumelana kahle kokugqwala kwe-monel 400 nezinzuzo ezingeziwe zamandla aphezulu nobulukhuni. Ukusebenza kungathuthukiswa ngokungeza i-aluminium ne-titanium kwi-matrix ye-nickel-Copper kanye nokushisa ngaphansi kwezimo ezilawulwayo ukuhlanganisa izinhlayiya ze-submicroscopic ze-NI 3 (TI, al) kulo lonke i-matrix.

Le ncwadi ye-nickel imelana ikakhulukazi nama-hydrochlecloric kanye nama-hydrofluoric acid lapho e-de-aerated. Njengoba kulindeleke ukuthi kulindelwe okuqukethwe kwethusi okuphezulu, i-Alloy 400 ihlaselwa ngokushesha yi-nitric acid kanye ne-ammonia systems.

Amapayipi e-Spools akhiqizwa ukusetshenziswa kwamapayipi aluhlaza kanye nokufakwa kwamapayipi. Inqubo yokusika yamapayipi eluhlaza yenziwa ngosayizi wamasehlakalo ofanele ukufakwa kwamapayipi nezinye izinto.

Ama-Superlloys ane-oxidation enhle nokumelana nokumelana okuhle futhi angaqiniswa ngezindlela ezinjengokuqina kwezulu, ikhambi lokuqina futhi usebenze kanzima. Bangasebenza futhi ngaphansi kwengcindezi emishini ephezulu kanye nokushisa okuphezulu nalapho kudingeka khona ukuqina komhlaba okuphezulu.

I-Alloy K500 yacwengiswa ngu-ElectroSlag Refining (ESR), iqinisekisa izinto ezihlanzekile nekhwalithi ephezulu kakhulu. Lokhu kukhuphuka kwe-alloy kukhawulela amandla okufakwa okuqinile okungabonakali okungakhuphule imishini, isikhathi semishini futhi ekugcineni kuholele ekuhlulekeni kwengxenye. Futhi inemvume ephansi futhi ayikho ama-magnetic emazingeni okushisa aphansi as -150¡Ãf (-101¡Ãc).

Ama-Flanges ayimpumputhe ukuhlukaniswa kokugcina kwesigaba se-flange. Zisetshenziswa njengezindela zokugcina zama-valves amapayipi noma amaphampu. Njengoba ama-flanges ayimpumputhe asetshenziswa njengezithiyo ngokumelene nokugeleza kwamanzi, ziyizingxenye eziphakeme kakhulu ze-flange systems.

I-Hastelloy B2 iyinqwaba ye-nickel-molybdenum alloy enokumelana okukhulu ekunciphiseni izindawo ezifana ne-hydrogen chloride igesi kanye ne-sulffuride igesi nama-sulfuric, acetic kanye phosphoric acids. I-Hastelloy B2 iyamelana ne-sulfuric acid emsulwa kanye nama-acid amaningi angewona oxidizing. Le alloy akufanele isetshenziswe phambi kokungcola oxidative in oxidizing noma ukunciphisa imidiya. Ukwehluleka ngaphambi kwesikhathi kungenzeka uma i-Alloy B2 isetshenziswa phambi kwensimbi noma ithusi ezinhlelweni eziqukethe i-hydrochloric acid.

I-Incons 718 isibe wusizo ezinhlobonhlobo zezicelo ezisukela ekusebenzeni kokukhiqiza emishini yezempi kanye nemboni ye-aerospace.

IHastelloy C-276 iphinde imelane kahle nokugqwala okukhohlisayo, ukugcwala kokugqwala kwengcindezelo nokuqhekeka kwe-oxidizing atmosheres, kanye nokumelana okuhle kwezindawo eziningi zamakhemikhali.
