Ipayipi Lenhlanzeko

ipayipi lenhlanzeko(ngokuvamile kuchazwa ngokuthitube sanitary) iyishubhu engagqwali eyenzelweinkonzo yenhlanzeko, lapho kufanele kube khona amapayipikuyahlanzeka,{0}}okungangcolisi, nokuhlolwa{1}}kunobungane. Empeleni, "sanitary" kuchazwa ngungaphakathi{{0}isimo sobuso nokuziphatha kokwenziwa: i-ID ebushelelezi, enesici{0}}elawulwayo engawuvimbi umkhiqizo, i-OD/WT ezinzile yokufakwa kwe-clamp fit{1}}phezulu kanye ne-orbital welding, kanye nesiphetho esingabambelela ngaphansiImijikelezo ye-CIP/SIPkanye nokugeza okujwayelekile ngaphandle kokuba yinkinga yokuhlanza.

Iningisanitary pipe insimbi engagqwalioda ukusetshenziswa304/304L noma 316/316L, kodwa ukusebenza ngokuvamile kunqunywa yilokho okubhalwe ngale kwebanga:ileveli yokuqeda (isb., i-BA lapho ukukhanya nokubamba kancane{2}}kubalulekile), ukubekezelela kobukhulu/ukuvuthwa, imibandela yokwamukela phezulu, kanye nobufakazi bokukhululwa(i-heat traceability + MTC) evumela ukuthi ishubhu idlule lapho kuhlolwa futhi iqonde ekufakweni.

Ishubhu ye-ASTM A270 yensimbi engagqwali ihlinzeka ngekhwalithi ephezulu yangaphakathi yendawo yezinhlelo zokuhlanzeka ezimbonini zokudla, iziphuzo, nemithi, lapho ukuhlanzeka nokumelana nokugqwala kubalulekile. Le tubing isekela ukuhlanzeka okuqinisekisiwe-endaweni{3}}(CIP) nokubulala amagciwane-ezinqubweni-zendawo (SIP), ukunciphisa izingozi zokungcola emithonjeni ebucayi efana namanzi ahlanzekile noma imikhiqizo yobisi. I-Octal Pipe inikeza isitoko ngamamaki avamile we-austenitic, iqinisekisa ukuthobelana nezindinganiso zomhlaba wonke zokusebenza okuthembekile.

Ishubhu ye-ASTM A270 ye-Octal Pipe inamathela kuzicaciso ze-ASTM A270/A270M zamashubhu ensimbi engenamthungo nashiselwe i-austenitic ne-ferritic/austenitic, okuhlanganisa nezimfuneko ezingeziwe zekhwalithi yomuthi. Iqondana ne-ASME BPE yezinto zokusebenza ze-bioprocessing kanye ne-ISO 2037 yokudla-amashubhu angagqwali ebanga, afaka amabanga afana no-304, 304L, 316, kanye no-316L. Ukuze uthole ukuqina okuthuthukisiwe ezindaweni ze-chloride, izinketho eziyi-duplex ezifana ne-2205 zihlangabezana nemibandela ye-ASTM A270 ngokuhlolwa okwengeziwe.

BA Qeda Sanitary Stainless Steel Pipe

I-BA (Bright Annealed)ishubhu sanitary ukhethwa lapho abathengi bafuna aindawo ekhanyayo, ebushelelezilokho kunciphisa ukubanjwa komkhiqizo-futhi kunciphise isikhathi sokuhlanza{1}}esivamile odongeni lobisi, isiphuzo, izimonyo, nezintambo zezinsiza zemithi. Uma kuqhathaniswa nepayipi-elijwayelekile lenjongo, ishubhu ye-BA sanitary izwela kakhulu ekukhiqizeni: njengoba ukushuba kodonga kukhula, ukugcinaudonga olufanayo, ukuphela kwe-OD/ID okuzinzile, nokubukeka okungaguquki kuba nzima, futhi izindleko zokuqeda zikhuphuka ngokufanele. Ngaleso sizathu, ama-oda e-BA ngokuvamile alawulwa incazelo yokuthenga ecacile: ibanga (304L/316L), usayizi, imfuneko yokuqedela, imibandela yokwamukela (isimo sobuso / isilawuli sobukhulu), kanye nephakethe ledokhumenti elizokhishwa.

Imikhawulo yamakhemikhali ku-ASTM A270 iqinisekisa ukumelana nokugqwala nokugqwala kwengcindezi, kuyilapho izakhiwo zemishini ziqinisekisa ubuqotho ngaphansi kwengcindezi yenqubo nge-ASME B31.3 ngayinye.

Ukuhlola okwenziwa ngomshini kuhlanganisa ukuqina namandla okukhiqiza, nokwakheka okusekela ubude ngesikhathi sokufakwa. Ku-316L, amandla amancane okudonsa afinyelela ku-515 MPa, isivuno ku-205 MPa, kanye nobude obungu-35%, aqinisekiswe ngezindlela ze-ASTM E8.

Amashubhu angenamthungo ngaphansi kwe-ASTM A270 aqala nge-extrusion noma ukubhoboza, kulandelwa umdwebo obandayo ukuze uthole ukunemba. Izinhlobonhlobo ezishiselwe zisebenzisa i-TIG yokushisela ngaphandle kokugcwalisa, enezinketho ezibanda kakhulu-ezisetshenzwayo zisebenzisa ukuncishiswa kodonga okungaphezu kuka-35% ngaphambi kokuxhunywa ukuze kuhlanganiswe isakhiwo. I-annealing yokugcina ekhanyayo emkhathini we-hydrogen kuqinisekisa i-oxide-izindawo ezikhululekile, ezihambisana ne-electropolishing ye-Ra Less than noma elilingana no-0.4 μm lapho kucacisiwe.

Amaphrothokholi ekhwalithi afaka ukuhlolwa kwe-hydrostatic kuya kungcindezi yokuklama izikhathi ezingu-1.5, i-eddy current yokukhubazeka, nokuhlolwa kwe-profilometer nge-ASME B46.1 ngayinye. Ukuhlolwa kwe-Borescope kuqinisekisa ukushibilika kwe-weld, kuyilapho i-positive material identification (PMI) iqinisekisa ikhemistri. Izitifiketi zokuhlolwa kwe-Mill nge-EN 10204 3.1 ngayinye zifaka amalogi okwelapha ukushisa nemibiko ye-NDT.

Ukubekezelelwa kwe-ASTM A270 kukhawula ukuhluka kwe-OD ukuya ku-±0.13 mm ngosayizi abangaphansi kuka-1 in, ifinyelela ku-±0.38 mm kumashubhu amakhulu, ukujiya kodonga kungabi ngaphansi kwegama elingaphezu kuka-12.5%. Ukuqondisa kubambe ku-0.5% wobude, kusekela ukufakwa okudonsa amanzi.

Isitokwe sigcizelela okushiselwe futhi kungenamthungo phakathi304L kanye 316L, enobude obungamamitha angu-6 ukuze iphathwe kahle. Isisindo sisebenzisa i-coefficient engu-0.02466 elungisiwe +1.2% yeqiniso-isisindo sokugcina ngaphansi kwesisindo sangempela. Osayizi kungenziwa ngezifiso; Ubukhulu obungafakwanga ohlwini butholakala ngesicelo.

Usesho oluningi lwabathengi luqhubekaishubhu ye-sanitary steel stainless (A270)ngoba i-A270 iyireferensi evamile yephrojekthi yamashubhu ahlanzekile. I-Octal Pipe isekela ukunikezwa kwamashubhu okuhlanzekile njengemizila engenamthungo neshiselwe, ecashunwe ngeleveli yokuqeda echaziwe (okuhlanganisa i-BA lapho kudingeka) kanye nokulandeleka kwenkatho.

Amadokhumenti okuhlola (MTC 3.1/3.2, imibiko ye-NDT) atholakala uma eceliwe.

Lapho kuhlolwaabahlinzeki bepayipi lokuhlanzeka, indlela eshesha kakhulu yokulawula-engozini yesayithi ukuhlolaelilinganisekayoizinto ezishayela ukuhlanzeka, ukulingana{0}}ukukhuphuka kwesivuno, kanye nesivinini sokukhulula{1}}ikakhulukazisanitary pipe insimbi engagqwaliamaphakheji (ASTM A270 sanitary tube).

Ukuphela kwendawo (ID) nokwamukelwa ngokuhlanzeka

• Chaza impokophelo yobunzima be-ID efana nendlela yokuhlanza:Ra Ngaphansi noma ilingana no-0.8 μmivame ukwamukelwa CIP/SIP amashubhu; imininingwane eqinile ingasethwa ibeRa Ngaphansi noma ilingana no-0.4 μm, kanye namaphrojekthi adinga{0}}ukuqinisekiswa kwezindawo zebanga angase acele ukupholishelwa phansi0.2 μm Ra.
• Yenza ukwamukela kubonakale: dingaamasheke wephrofayili(amarekhodi okurhabaxa) bese ucacisa ukuthi yini ebaluleke njengokunqatshwa ku-ID/OD (isb., imihuzuko, imigodi, izimpawu zokupholisha, ukuguquguquka kombala)ngezithombe noma imikhawulo yokukhubazeka-ngakho-ke ukuthola ukuhlolwa akukona ukuzenzela.
• I-Octal Pipe ngokuvamile iqondanisa i-PO ku-aelilinganisekayokhulula:amarekhodi ephrofayili (imibiko ka-Ra) ngenkatho, kanye nolimi olucacile lokwenqaba lwe-ID/OD (imigodi, amaphuzu aqhubekayo, ukushintsha kombala) ngakho ukuthola ukuhlolwa akukona okucabangelayo.

Ubukhulu nobuqotho (yini egcina amajoyinti e-orbital welding kanye nama-clamp azinzile)

• Khiya iwindi likasayizi ngaphambili: ibanga elijwayelekile le-OD lenhlanzeko ngu0.5-12 in.
• Memezela ukubekezelelana ku-PO ukuze ukwakheka "kungakutholi" esizeni: Ukubekezelelwa kwe-OD kungaqina njengoba±0.13 mm(kwe<1 in), scaling up to ±0.38 mmosayizi abakhulu; ukujiya kodonga ngokuvamile kulawulwa kanjalo kunjalohhayi ngaphansi kwegama elingaphezu kuka-12.5%; ukuqondisa kuvame ukubanjelwa kukho0.5% wobudeukusekela umzila odonsa amanzi kanye nokuqondanisa kwe-clamp okubikezelwayo.

Isilawuli se-seam se-sanitary tube esishiselwe - senza ubufakazi bokwamukela-kusekelwe

• Kuthubhu ye-sanitary eshiselwe, umthungo awuyona ilebula ethi yebo/cha. Abathengi ngokuvamile badinga indlela ecacile: okuzenzakalelayoUkushisa kwe-TIG(ngokuvamile okuzenzakalelayo), kanye nendlela yokuhlola efakazela isimo sangaphakathi.
• I-Octal Pipe ivame ukusekelaukuhlolwa kwamanje kwe-eddyyokulawula ukukhubazeka kweshubhu futhi ungangezaukuhlolwa kwe-borescope seamngobude bokumela abanye lapho ulayini uzwela-ubalulekile (ukuvikela-ukusebenza kabusha kwesiteji ngemva kokufakwa).

I-Sanitary Pipe Price - Yini Empeleni Ehambisa Izindleko

Intengo yepayipi lenhlanzekongokuvamile iqhutshwa isethi encane yezinto eziguquguqukayo zangempela:ibanga (304L vs 316L), imfuneko yokuqeda (i-BA kanye nokulindelwe okuqinile kwendawo), usayizi (OD/WT), kanyeiphakheji yokukhulula(izinga lokulandeleka, ububanzi bokuhlola, nanoma yikuphi-ukufakaza okuvela eceleni). Kumaphrojekthi okuhlanzeka, "ishubhu eshibhile" ivamise ukubiza kakhulu uma -ukuhlanza, izinqwaba ezinqatshiwe, noma ukushisela kabusha kubalwa. Ukuqhathanisa ikhwothi ehlanzekile ukuqondisa imigqa emithathu kubo bonke abahlinzeki: inkomba evamile efanayo (isb, i-A270 lapho isebenza), incazelo efanayo yokuqedela, kanye nobufakazi obufanayo bokukhululwa obudingekayo ekutholeni.

Izingxabano zokuhlanzeka (ishubhu libukeka lilihle, kodwa i-CIP/SIP ngeke idlule)
Ingozi efihliwe iyonaIndawo ye-ID: ama-micro-ama-scratches, izimpawu zokupholisha, ukushintsha kombala, noma imigodi yendawo eba amaphuzu{1}}aphezulu wokubamba umkhiqizo. Amasayithi akuzwa njengesikhathi eside se-CIP, ama-swabs aphindayo, noma izinsalela ezingachazwanga kumajoyinti e-spool.
I-Octal Pipe iyilawula kanjani:asishiyi "ipholishiwe/i-BA" njengelebula elingacacile. I-PO iqondaniswe ne-aumgomo wokuqeda olinganisekayo(imvamisa u-Ra{0}ngokususelwe lapho iphrojekthi ikudinga), futhi ukwamukelwa kubhalwa njengesiciumthetho wokuhlola(iziphi iziphambeko ezinqatshwa ku-ID/OD). Inqwaba ikhishwa enobufakazi obuphezulu/bokugcina obuboshelwe ekuthunyelweni ukuze ukuthola ukuhlolwa kungaphenduki kube impikiswano engokoqobo.

Ishubhu ehlanzekile ilethwe ingcolile (ukuphatha ukungcola)
Ngisho namashubhu amahle ayanqatshwa uma i-ID ifika nothuli, izimpawu zomswakama, noma izinsalela-ikakhulukazi ku-WFI kanye namaluphu e-biotech lapho ukwamukelwa kuqinile khona namawindi esikhathi esifushane.
I-Octal Pipe iyilawula kanjani:ukuthunyelwa kuthathwa njengengxenye yenhlanzeko:amakepisi okugcina, ukugoqa okuvaliwe, nokuhlanganisa okulawulwayo, ngamaphakheji avimbela ukungcoliswa kwe-ID kanye nokulimala kwendawo phakathi nokulayisha/ukulayisha. Lokhu kuvame ukuhluka phakathi kwamashubhu angaqonda ngqo{1}}kanye namashubhu ahlezi evalekile alinde{2}}ukuhlanzwa kabusha.

Izikhala zokulandela umkhondo (ishubhu likhona, kodwa i-QA ayikwazi ukuyikhulula)
Imodi yokwehluleka evamile incwadi engakwazi ukufaniswa ngokushesha: imephu yokushisa engekho, ama-ID enqwaba angacacile, noma izitifiketi ezingahambelani nokumaka ishubhu. Umphumela ulula{1}}okubalulekile okuhlala esizeni, futhi iphrojekthi ilahlekelwa iwindi layo lokuvala shaqa.
I-Octal Pipe iyilawula kanjani:sithumela ngochungechunge olufundekayo:ukumakwa kweshubhu → ukushisa/imephu yenqwaba → MTC (EN 10204 3.1), ngakho-ke ukuthola ukuhlolwa kungamukela noma kuhlukanise ngenqwaba ngaphandle kokuqagela. Lapho amaphrojekthi edinga isiqiniseko esiphezulu,3.2 / -ukufakaza okuvela eceleniingahlelwa, kodwa isisekelo sihlale "singukukhululwa okusheshayo, okuqinisekiswayo."

Ishubhu ye-ASTM A270 ifanele imigqa yokudlulisa yobisi ephethe ama-slurries, amalophu ekhemisi emanzini-o-womjovo (WFI), namasistimu okuvutshelwa kwe-biotech. Ingaphakathi layo elibushelelezi livimbela ukunamathela kwebhaktheriya ekucutshungulweni kokudla, kuyilapho amabanga{4}ekhabhoni aphansi amelana nokuzwela-kumjikelezo we-CIP wezinga lokushisa eliphezulu. Kumidiya ehlukumezayo, okuhlukile kwe-duplex kunweba impilo endaweni ye-chloride{7}}ecebile njengethayi lokususa usawoti emanzini olwandle{8}}.

I-Sanitary tube ivame ukucaciswa lapho "inkinga yangempela" yenzeka khonangesikhathi sokusebenza nokuhlanza, hhayi emdwebeni.
