Ukubukelwa kwepayipi kungenye yamakhono ethu ayisisekelo.

Ama-Pipe Spool Systems asetshenziswa kakhulu ezitshalweni zamandla kanye nama-petroleum Remineries adinga amapayipi anzulu. Lezi zinhlelo zifaka ukuthwala kanye nokuthuthwa koketshezi kanye negesi futhi lezi zinhlelo zokuhamba zidinga izingxenye eziningi zokuxhuma. Kulezi zinhlelo, ayikho indawo yamaphutha.

Le alloy lensimbi ye-nickel imelana nokuvikelwa okuhle ekushiseni okuthintekayo nokuhlaselwa kone okune-Knife-line. Le alloy ibuye ibeke i-brunt ye-formic, sulfuric, phosphoric, acetic acids kanye neminye imithombo yezindaba engekho oxinizing.

Ukumelana ne-Chloride Ion Corrision kungenye yezinto eziphambili ezenza kube lula ukusetshenziswa kwamabanga we-incoloy ezihlolweni ezahlukahlukene zezimboni.

Ngokungezwa kwe-nitrogen njenge-ejenti eqinisayo, i-alloy ingaba nesiqinisekiso esimbili njengo-Alloy 317 (ama-S31700).

Ama-elbows ngokuvamile asetshenziselwa ushintsho ekuqondisweni kokugeleza. Izinhlelo ezijwayelekile ze-elbow zingashintsha i-angle yokugeleza ngo-180¡Ã, 90¡Ã noma i-45¡Ã noma i-45¡Ã noma i-45¡Ã. Uhlelo lwe-180¡Ã elbow lubizwa nangokuthi ¡® ®return bend¡¯. Amasistimu we-elbow angahlukaniswa abe ngamaqembu amabili ayi-butt weld elbows kanye nokunciphisa ama-elbows. I-butt-welded elbows iyizakhi ezivame kakhulu futhi ezifiselekayo.

Ukuphikiswa okuvelele okuvelele futhi okuguquguqukayo kwe-inconel 625 alloy ngaphansi kwamazinga okushisa kanye nezingcindezi kuyisizathu esiyinhloko sokwamukelwa kwayo okubanzi kwensimu yamakhemikhali.

Amabanga amabili ajwayelekile ensimbi ajwayelekile angama-304 no-316. Umehluko omkhulu ukufakwa kwe-molybdenum, i-alloy ethuthukisa kakhulu ukumelana nokukhulisa, ikakhulukazi ezindaweni ezinosawoti noma nge-chloride.

I-InColel iyi-superelloy eyenziwe ngokugxila okuphezulu kwe-nickel, i-chromium kanye ne-molybdenum. I-Incons 625 imelana kakhulu nemidiya ye-Contosive and oxidizing ezindaweni ezahlukahlukene. Lezi ze-alloys zinomkhondo omuhle kakhulu nokulukulela okuhle. Zingafakwa kalula futhi zimelana ne-post-weld carburhation noma ukusanhlamvu.

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.

I-Incons 718 iyi-superalloy esekelwe e-nickel elungele izinhlelo zokusebenza ezidinga amandla aphezulu ebangeni lokushisa elivela ku-crygenic kuya ku-1400¡ãff. I-InComel 718 nayo inamandla amahle kakhulu we-Tensile nemphumela.

I-Hastelloy C276 yaziwa ngokumelana kwayo okuhle kakhulu kokugqwala kwemidiya ehlukahlukene. Kubandakanya i-chloride ion, amakhompiyutha esibabule, njll. Ngaphezu kwalokho, le alloy inokumelana kahle nokugqwala kwama-crevice, ukugqwala okukhonkotha kanye nokuqhekeka kokugqwala kwengcindezi. Kuyasiza ukumelana nemiphumela elonakalisayo ye-chlorine emanzi, i-chlorine dioxide ne-hypochlorite. Lo mkhiqizo ulungele izinhlelo zokusebenza zamanzi olwandle.

Ukusetshenziswa kokwakhiwa kwe-modular kuthonywa ngokuqondile yizidingo zeklayenti nto nto esheshayo yokwakha, ikhwalithi, izinzuzo ezingezekile zezomnotho zesilinganiso, kanye nokuthengwa kwamaphuzu okukodwa.

I-Plasma Arc Cutter isetshenziselwa amapayipi amakhulu (ngenhla kwama-intshi angama-28 wosayizi wepayipi oyisikhonkwane) nokusetshenziswa kwayo nakho kuzuzisa ukusika amagatsha. Uma kungenzeka, icala langaphakathi kumele libe ngamapayipi noma ukufakwa, ukuze livikeleke eziswindi ezidalwe yi-plasma arc cutter. Ngemuva kokusika, nokulungiselela onqenqemeni kumele kugcinwe.

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.

Ama-flanges ahlangene ane-lap anesimo esilinganayo esifana neSocket Weld Flenges ngaphandle kwegebe le-Weld. Ngakho-ke, ukusetshenziswa kwabo kuzinhlelo zokusebenza ezingadala ukugqwala kunzuzo. Olunye uhlobo lwe-flange amafulethi afakwe intambo. Ama-flanges ahlanganisiwe asiza kakhulu kwizicelo ezithile ngoba azidingi ukuthutha ukulungiswa.

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

I-Hastelloy B-2 i-nickel-base yenza i-alloy enomqondo omuhle kakhulu we-hydrochloric acid kuwo wonke amazinga okuhlala kanye namazinga okushisa.

Ukuguquguquka kwamanye amazwe kwe-Incon 600 Alloy kuyakuvumela ukuthi kusetshenziswe ezinhlobonhlobo zezicelo ezibandakanya amazinga okushisa aqhamuka emazingeni okushisa ama-cryogenic kuya ngaphezulu kwe-2000¡Ãf (1095¡Ãc (1095¡Ãc (1095¡Ãc).

Le alloy isetshenziswa kabanzi embonini yamakhemikhali ngamandla ayo nokuphikiswa kokugqwala. Izicelo zifaka ama-heater, namanje, amakholomu bubble, kanye nama-condenser ngokusebenza kwamafutha acid; Amashubhu we-Evaporator, amashidi we-tube, kanye namathrayidi aqediwe wokwenziwa kwe-sodium sulfide; nemishini yokucubungula i-abitic acid ekukhiqizeni i-pulp.

Umndeni weMoly unekhono lokumelana namazinga okushisa aphezulu futhi alondoloze amandla ngaphansi kwezimo eziguqukayo.

Kuklanyelwe ukuhlanganiswa kobunzima bokuqina kobunzima bokugqwala kwe-chloride ukuqhekeka kokuqhekeka, kanye nokugqwala okukhohlisayo kanye nokugqwala kwamandla ngamandla okuphindwe kabili kochungechunge lwensimbi engama-300.

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

I-templen steel s Sebenzisa ngokunenzuzo ukuqalwa kwe-offsite ukuthuthukisa ijubane noma ukwakheka nokubikezelwa kwezindleko zesisombululo.

Amapayipi amapayipi abunjwe ngaphambili ukwenza lula ukuhlanganisa ukusebenzisa ama-hoist, ama-gauges namanye amathuluzi okujoyina izingxenye. Amapayipi Spools ahlanganisa amapayipi amade ngama-flanges avela ekugcineni kwamapayipi amade ukuze agoqwena ngogesi ofanayo.

Amapayipi okubutha igesi omuncu akhiwe nge-cood (noma ehlanganisiwe) infoltel? I-625 alloy futhi isetshenziswa ekushiseni okushisa kwamanzi olwandle ezindaweni zokuhlaziya, izitshalo zamandla, kanye nezinsizakalo eziphezulu zaphezulu ezivame ukudinga lokhu okuqukethwe.

I-Alloy C-276 futhi inokumelana kahle nokuphamba, ukuqhekeka kokugqwala kokugqwayiza kanye no-oxidizing atmosperes aze afike ku-1900¡ãf. I-Alloy C-276 inokumelana okuhlukile ezindaweni ezahlukahlukene zamakhemikhali.

Ine-nickel ephezulu (24%), i-molybdenum (6.3%), i-nitrogen kanye nokuqukethwe kwe-chromium okunikeza ukumelana kahle nokuqhekeka kokugqwala kwe-chloride, i-chloride ukumelana, kanye nokuphikiswa okujwayelekile kokugqwala.

I-Monel 400 isetshenziswa emikhunjini yenqubo, amapayipi okushisa okushisa, kanye nophethiloli namathangi okugcina amanzi akhona emkhakheni wasolwandle. Izakhiwo ezingezona ezikhazimulayo zalolu alloy zikwenza lulungele izimo ezinobungozi obukhulu kubamboni bezindawo eziqhumayo, amarokhethi kanye nezimboni zamaphepha.

Njengokuqala kokukhiqiza, zonke izinto kufanele zimakwe ukuze zikhulise ukubonwa kwezinto zokwakha. Umsebenzi wokumaka ungaqaliswa ngenxa yenombolo ethile yezakhi. Ngaphezu kwalokho, zonke izilinganiso zepayipi amapayipi kumele zikubekele zona. Ukulandelwa kwezakhi akumele kungcolise impahla ngaphandle kokulandela kungasabela ngezinto ezibonakalayo futhi lokhu kungadala izinkinga ezisusiwe.
