Umbhobho ococekileyo

umbhobho wococeko(ihlala ichazwa njengeityhubhu yococeko) yityhubhu engena stainless eyenzelweinkonzo yococeko, apho kufuneka kube khona umbhobhoicocekile,-engangcolisi, kwaye ihlolwe{1}}nobuhlobo. Ngokwesiqhelo, "ucoceko" luchazwa ngungaphakathi{0}imeko yobuso kunye nokuziphatha kokwenziwa: i-ID egudileyo, eneziphene{0}}elawulwa yi-ID engabambisi imveliso, i-OD/WT ezinzileyo yokulingana okubambekayo{1}phezulu kunye ne-orbital welding, kunye nesiphelo esinokubambelela ngaphantsi.Imijikelo ye-CIP/SIPkunye nokuhlamba okuqhelekileyo ngaphandle kokuba yingxaki yokucoca.

Uninziumbhobho we-sanitary steel stainlesssebenzisa imiyalelo304/304L okanye 316/316L, kodwa ukusebenza kudla ngokugqitywa ngento ebhalwe ngaphaya kwebakala:inqanaba lokugqiba (umzekelo, iBA xa kuqaqamba kunye nokubamba okuphantsi{2}}izinto eziphezulu), ukunyamezelwa kobukhulu/ukuvuthwa, indlela yokwamkelwa komphezulu, kunye nobungqina bokukhupha(ukulandeleka kobushushu + MTC) evumela ukuba ityhubhu idlule ekuhlolweni kwaye uye ngqo kufakelo.

I-ASTM A270 ye-sanitary stainless steel tubing ibonelela ngomgangatho ophezulu wangaphakathi womgangatho weenkqubo zococeko kumashishini okutya, isiselo, kunye namayeza, apho ucoceko kunye nokumelana nokubola kubalulekile. Le ityhubhu ixhasa ukucoceka okuqinisekisiweyo -kwindawo{3}}(CIP) kunye nokucoca{4}}kwindawo{5}}inkqubo (SIP), ukunciphisa umngcipheko wongcoliseko kumajelo osasazo anovakalelo njengamanzi asulungekileyo okanye iimveliso zobisi. I-Octal Pipe ibonelela ngesitokhwe kumabakala afanayo e-austenitic, eqinisekisa ukuthotyelwa kwemigangatho yehlabathi yokusebenza okuthembekileyo.

I-Octal Pipe's ASTM A270 yetyhubhu yococeko ibambelela kwiinkcukacha ze-ASTM A270/A270M zemibhobho yentsimbi engenamthungo kunye ne-austenitic edityanisiweyo ne-austenitic/austenitic, kuquka iimfuno ezongezelelweyo kumgangatho wamayeza. Ilungelelaniswa ne-ASME BPE yezixhobo ze-bioprocessing kunye ne-ISO 2037 yokutya -iityhubhu ze-stainless stainless, ezigquma amabanga afana ne-304, 304L, 316, kunye ne-316L. Ukomelezwa kokuqina kokusingqongileyo kwekloridi, iinketho eziphindwe kabini ezifana ne-2205 zidibana neenqobo ze-ASTM A270 ngovavanyo olongezelelweyo.

BA Gqibezela Sanitary Stainless Steel Pipe

BA (I-Anealed eqaqambileyo)iityhubhu ezicocekileyo zikhethwa xa abathengi befuna aumgangatho oqaqambileyo, ogudileyooko kunciphisa ukubanjwa kwemveliso-kwaye kunciphisa ixesha lokucoca{1}}eliqhelekileyo kwimveliso yobisi, isiselo, izinto zokuthambisa, kunye nemigca yoncedo loxubo. Xa kuthelekiswa nenjongo jikelele-umbhobho ongenanto, i-BA sanitary tubing inovakalelo kuqeqesho lokwenziwa: njengoko ubuninzi bodonga busanda, ukugcinaudonga olufanayo, ukugqiba kwe-OD / ID ezinzileyo, kunye nokubonakala okuhambelanayo kuba nzima, kwaye iindleko zokugqiba ziphakama ngokufanelekileyo. Ngenxa yeso sizathu, imiyalelo ye-BA ilawulwa ngokuqhelekileyo ngenkcazo yokuthenga ecacileyo: ibakala (304L / 316L), ubungakanani, imfuno yokugqiba, imilinganiselo yokwamkelwa (imeko yobuso / ulawulo lwe-dimensional), kunye nepakethe yoxwebhu lokukhululwa.

Imida yeMichiza kwi-ASTM A270 iqinisekisa ukuxhathisa kwi-pitting kunye noxinzelelo lwe-corrosion, ngelixa iipropathi zomatshini ziqinisekisa ingqibelelo phantsi koxinzelelo lwenkqubo nge-ASME B31.3.

Uvavanyo lomatshini lubandakanya ukuqina kunye namandla emveliso, kunye nobude obuxhasa ukubumba ngexesha lofakelo. Kwi-316L, amandla amancinci afikelela kwi-515 MPa, isivuno kwi-205 MPa, kunye ne-elongation kwi-35%, iqinisekiswe ngeendlela ze-ASTM E8.

Ityhubhu engenamthungo phantsi kwe-ASTM A270 iqala nge-extrusion okanye ukugqobhoza, ilandelwe ngumzobo obandayo wokuchaneka. Izahluko ezidityanisiweyo zisebenzisa i-TIG ye-welding ezenzekelayo ngaphandle kwesigcwalisi, kunye nokubanda kakhulu{2}}ukhetho olusebenzayo olusebenzisa ngaphezulu kwe-35% yokunciphisa udonga ngaphambi kokuba i-anneal ukwenza i-homogenize isakhiwo. I-annealing yokugqibela eqaqambileyo kwi-atmosfera ye-hydrogen iqinisekisa i-oxide{5}}imigangatho ekhululekileyo, encediswa yi-electropolishing ye-Ra Ngaphantsi okanye ilingana no-0.4 μm apho kuchaziwe.

Iiprothokholi zomgangatho zibandakanya uvavanyo lwe-hydrostatic ukuya kuxinzelelo lwe-1.5 loyilo lwamaxesha, i-eddy yangoku kwiziphene, kunye nokuhlolwa kweprofilometer nganye ye-ASME B46.1. Uhlolo lwe-Borescope luqinisekisa ukugungxula kwe-weld, ngelixa i-positive material identification (PMI) iqinisekisa i-chemistry. Izatifikethi zovavanyo lwe-Mill nge-EN 10204 3.1 ziquka iilog zonyango lobushushu kunye neengxelo ze-NDT.

Ukunyamezela kwe-ASTM A270 ukukhawulela ukuguquguquka kwe-OD ukuya ku-± 0.13 mm ngobukhulu obungaphantsi kwe-1 ku-, ukulinganisa ukuya kwi-± 0.38 mm kwiityhubhu ezinkulu, kunye nobukhulu bodonga bungekho ngaphantsi kwe-12.5%. Ukuthe tye kubambe i-0.5% yobude, ixhasa ukufakelwa kwamanzi.

Isitokhwe sigxininisa i-welded kwaye ingenamthungo ngaphakathiI-304L kunye ne-316L, kunye nobude kwiimitha ezi-6 zokuphatha ngokufanelekileyo. Ubunzima busebenzisa i-coefficient ye-0.02466 ehlengahlengisiweyo +1.2% yenyani{4}}ubunzima bokugqibela ngokuxhomekeke kubunzima bokwenene. Ubungakanani bunokwenziwa ngokwezifiso; imilinganiselo engadweliswanga ekhoyo xa iceliwe.

Abathengi abaninzi bajonga umhlabaiityhubhu ecocekileyo yentsimbi (A270)ngenxa yokuba i-A270 sisalathiso seprojekthi eqhelekileyo kwityhubhu ecocekileyo. Umbhobho we-Octal uxhasa unikezelo lwetyhubhu yococeko njengeendlela ezingenamthungo nezidityanisiweyo, ezicatshulwe ngenqanaba lokugqiba elichaziweyo (kuquka i-BA xa kuyimfuneko) kunye nokulandeleka okuninzi.

Iidosi zokuhlola (MTC 3.1/3.2, iingxelo ze-NDT) ziyafumaneka xa ziceliwe.

Xa kujongwaababoneleli ngemibhobho yococeko, eyona ndlela ikhawulezayo yokulawula{0}}kumngcipheko wesayithi kukuphicothainokulinganiswaizinto eziqhuba ukucoceka,-ukunyusa isivuno, kunye nesantya sokukhulula{1}}ingakumbi kwiumbhobho we-sanitary steel stainlessiiphakheji (i-ASTM A270 ityhubhu yococeko).

Ukugqitywa komphezulu (ID) kunye nokwamkelwa kococeko

• Chaza i-ID erhabaxa ekujoliswe kuyo ehambelana nendlela yokucoca:Ra Ngaphantsi okanye ilingana no 0.8 μmngokuqhelekileyo yamkelwe kwityhubhu ye-CIP/SIP; i-specs eqinile inokusetwa kuyoRa Ngaphantsi okanye ilingana no 0.4 μm, kunye neeprojekthi ezifuna uqinisekiso{0}}imiphezulu yomgangatho inokucela ukugudiswa ukuya kuthi ga0.2 μm Ra.
• Yenza ulwamkelo lubonakale: funaiitshekhi zeprofayili(iirekhodi zokurhabaxa komhlaba) kwaye ucacise ukuba yintoni na ebalwa njengokukhatywayo kwi-ID/OD (umz., imikrwelo, imingxuma, amanqaku okupholisha, ukujika kombala)ngeefoto okanye imida yesiphene-ngoko ukufumana uhlolo akuzicingeli.
• Umbhobho we-Octal ulungelelanisa i-PO kwi-ainokulinganiswaKhupha:iirekhodi zeprofilometer (iingxelo zeRa) ngeqashiso, kunye nolwimi oluchasayo olucacileyo lwe-ID/OD (imingxuma, amanqaku aqhubekayo, i-discoloration) ngoko ke ukufumana uhlolo akukhethi buso.

Imilinganiselo kunye nokuthe tye (yintoni egcina i-orbital welding kunye ne-clamp joints zizinzileyo)

• Tshixa ubungakanani befestile ngaphambili: uluhlu oluqhelekileyo lwe-OD lococeko lu0.5-12 ngaphakathi.
• Biza unyamezelo kwi-PO ukuze imveliso "ingabhaqi" kwindawo: Ukunyamezela kwe-OD kunokuqina njengoko±0.13 mm(ye<1 in), scaling up to ±0.38 mmkwiisayizi ezinkulu; ubukhulu bodonga ngokuqhelekileyo bulawulwa ngoko bunjalohayi ngaphantsi kwe-12.5%; ngokuthe tye kudla ngokubanjwa0.5% ubudeukuxhasa umzila wokutsalwa kwamanzi kunye nolungelelwaniso lweclamp oluqikelelwayo.

Ulawulo lomthungo oludityanisiweyo lwetyhubhu- yenza ubungqina bokwamkelwa - kusekwe

• Kwityhubhu edityanisiweyo yococeko, i-seam ayikho ileyibhile ye-ewe / hayi. Abathengi badla ngokufuna indlela ecacileyo: ngokuzenzekelayoTIG ukuwelda(kaninzi i-autogenous), kunye nendlela yokuhlola ebonisa imeko yangaphakathi.
• I-Octal Pipe idla ngokuxhasaUvavanyo lwangokukulawulo lwesiphene sombhobho kwaye unokongezaiitshekhi borescope umthungokubude bommeli xa umgca unobuntununtunu-ubalulekile (ukuthintela kade{1}}ukuphinda kusebenze emva kofakelo).

Ixabiso lombhobho wococeko - Yintoni eneneni ehambisa ixabiso

Ixabiso lombhobho wococekoidla ngokuqhutywa liqela elincinci lezinto eziguquguqukayo zokwenyani:ibakala (304L vs 316L), imfuneko yokugqiba (i-BA kunye nolindelo olungqongqo phezu komhlaba), ubungakanani (OD/WT), kwaye iiphakheji yokukhulula(inqanaba lokulandelelwa, umda wovavanyo, kunye naluphi na -ubungqina beqela lesithathu). Kwiiprojekthi zococeko, "ityhubhu etshiphu" ihlala iyeyona ibiza kakhulu xa kubalwa kwakhona ukucoca, ukwaliwa kwamaqashiso, okanye ukuwelda kwakhona. Uthelekiso lwekowuti olucocekileyo kukulungelelanisa imigca emithathu kubo bonke ababoneleli: ireferensi esemgangathweni efanayo (umzekelo, i-A270 xa ifanelekile), inkcazo yokugqiba efanayo, kunye nobungqina obufanayo bokukhululwa obufunekayo ekufumaneni.

Iingxabano zokucoceka (ityhubhu ibonakala ilungile, kodwa i-CIP/SIP ayiyi kudlula)
Umngcipheko ofihliweyo yiUmphezulu we-ID: imikrwelo emincinci,-impawu zokupholisha, ukujika kombala, okanye imingxunya yasekuhlaleni ethi ibe ngamanqaku emveliso{1}}ephezulu. Iisayithi zivakalelwa kukuba lixesha elide le-CIP, ukuphinda i-swabs, okanye iintsalela ezingachazwanga kwiindawo ze-spool.
Uyilawula njani i-Octal Pipe:asishiyi "ipolishiwe/BA" njengeleyibhile engacacanga. I-PO ihambelana ne-aIthagethi yokugqiba enokulinganiswa(ngokuqhelekileyo i-Ra{0} isekelwe xa iprojekthi iyifunayo), kwaye ulwamkelo lubhalwa njengeumthetho wokuhlola(zeziphi iziphene ezikhatywayo kwi-ID/OD). Amaqashiso akhululwa kunye nobungqina bomphezulu / bokugqibela obubotshelelwe emva ekuthunyelweni ukuze ukufumana uhlolo kungajiki kube yingxoxo ebambekayo.

Ityhubhu ecocekileyo iziswe imdaka (ukuphatha ungcoliseko)
Nkqu netyhubhu elungileyo iyaliwa ukuba i-ID ifike inothuli, iimpawu zokufuma, okanye inkunkuma{0}}ingakumbi kwi-WFI kunye ne-biotech loops apho ukwamkelwa kungqongqo kunye nexesha elifutshane lefestile.
Uyilawula njani i-Octal Pipe:Ukuthunyelwa kuthathwa njengecandelo lococeko:iminqwazi yokuphela, ukusonga okutywiniweyo, kunye nokubopha okulawulwayo, kunye nokupakishwa okuthintela ukungcoliseka kwe-ID kunye nokulimala kwendawo ngexesha lokulayisha / ukukhulula. Oku kuqhelekile ukuba ngumahluko phakathi kwetyhubhu enokuthi ingene ngokuthe ngqo{1}}kunye netyhubhu ehleli kwindawo yodwa ilinde{2}} ukucocwa kwakhona.

Izithuba zokulandela umkhondo (ityhubhu ikhona, kodwa i-QA ayikwazi ukuyikhulula)
Imowudi yokungaphumeleli eqhelekileyo ngamaphepha angenako ukudityaniswa ngokukhawuleza: ukungabikho kwemephu yobushushu, ii-ID ezingacacanga, okanye izatifikethi ezingahambelani nokuphawulwa kwetyhubhu. Iziphumo zilula{1}}izinto ezihlala kwisiza, kwaye iprojekthi ilahlekelwa yifestile yokuvala.
Uyilawula njani i-Octal Pipe:sithumela ngekhonkco eliphicothwayo:ityhubhu yokuphawula → ubushushu/imephu yeqashiso → MTC (EN 10204 3.1), ngoko ke ukufumana uhlolo kunokwamkela okanye ukwahlula ngenqwaba ngaphandle kokuqikelela. Xa iiprojekthi zifuna isiqinisekiso esiphezulu,3.2 / umntu wesithathu -ubungqinainokulungiswa, kodwa isiseko sihlala "sikhawuleza, ukukhululwa okuqinisekisiweyo."

I-ASTM A270 yetyhubhu ifanela imigca yogqithiselo yobisi ephethe i-slurries, iilophu zamayeza zamanzi{1}}e{2}}zokutofa (WFI), kunye neenkqubo zokuvundiswa kwebhayoloji. Ingaphakathi layo eligudileyo linqanda ukunamathela kwebhaktiriya ekusetyenzweni kokutya, ngelixa amabanga asezantsi{4}ekhabhoni axhathisa ulwazelelelo kwimijikelo - yobushushu obuphezulu beCIP. Kumajelo osasazo andlongondlongo, ukwahluka kwe-duplex bandisa ubomi kwikloridi{7}}imekobume ezityebileyo ezifana neqhina lokukhupha ityuwa emanzini olwandle{8}}.

I-tube yococeko idla ngokuchazwa apho "ingxaki yokwenyani" yenzekangexesha lokusebenza kunye nokucoca, kungekhona kumzobo. Apha ngezantsi kukho iimeko eziqhelekileyo zangaphambili kwi-Octal Pipe ebonwa kwiipakethe zococeko{1}}ezibhalwe ngendlela efanayo namaqela e-QA athetha ngayo kwindawo:

• I-WFI /{0}}acociweyo{0}}iingcingo ezirhintyela emva kokulungiswa kokuvalwa:ngexesha lokuqalisa kwakhona, i-loop iyagungxulwa, ifudunyezwe, kwaye isampuliwe. Izinto ezisilelayo iiprojekthi zihlalaubume bomphezulu kunye nokuphatha ungcoliseko(Ukungcola kwe-ID, ukungena komswakama, amaqashiso axubileyo). I-Octal Pipe ikholisa ukupakisha ityhubhu yococeko eneziphelo ezivaliweyo kunye neqashiso{1}}nezatifikethi ezifakwe kwimaphu ukuze isiza silandele amanani obushushu ngokukhawuleza kwaye sinqande kwakhona-ukucoca okanye ukuvalelwa okubangelwa bubungqina obungekhoyo.
• Ukuvutshelwa / ufakelo lwebhayotekhi yokutyibilika (ukuhlamba rhoqo + ukukhwela ibhayisekile eshushu):Ityhubhu ibona imijikelo ephindaphindiweyo eshushu-ebandayo kunye nokucocwa kweekhemikhali. Intlungu yomsebenzi yiUkutshintsha kombala, uburhabaxa, kunye nomngcipheko wokwazisa malunga nobushushu be-weld{0}}iindawo ezichaphazelekayoukuba izinto/ukugqiba akuhambelani. Amabanga asezantsi{{1}ekhabhoni kunye nesiseko esichaziweyo sinciphisa iposti-efakela izinto ezothusayo zokucoca kunye nokunciphisa ixesha lokuqinisekisa.
• Phezulu-i-chloride esebenza ngokubambisana{1}}i-ins (ibrine/Caustic{2}}yokucoca kufutshane):umceli mngeni awukho "umhlwa ngokubanzi" kodwaimingxuma yendawo kwimingxuma, ibambene, kunye-nemilenze efileyoemva kokutyhileka okuphindaphindiweyo okumanzi-nokoma. Kwezi phakheji, ukhetho lwezinto eziphathekayo (ngokuqhelekileyo zihamba ukusuka kwi-304L ukuya kwi-316L okanye i-duplex nge-spec) igqitywe yi-chemistry yokuhlamba ngokuthe ngqo kunye ne-downtime real reality, kungekhona ileyibhile yencwadana.
