Amapayipi angenamthungo ensimbi engagqwali asephenduke abalulekile kuzo zonke izinhlobo zezimboni, ngenxa yokumelana kwawo nokugqwala okumangalisayo, amandla, kanye nokuthembeka ezindaweni ezimbi kakhulu. Ngokungafani namapayipi ahlanganisiwe, izinhlobo ezingenamthungo zenziwa ngaphandle kwamalunga, okuholela esakhiweni esifanayo kanye nezakhiwo ezithuthukisiwe zemishini. Lesi sihloko sihlola amazinga amakhulu okusebenza emhlabeni wonke alawula amapayipi angenamthungo ensimbi engagqwali, kanye nokubuka okujulile ububanzi bokusetshenziswa kwawo okubanzi.
Izindinganiso Zokusebenza Zamapayipi Angenamthungo Ensimbi Engagqwali
Amapayipi angenasici angenamthungo akhiqizwa ukuze ahlangabezane nezindinganiso eziqinile zamazwe ngamazwe nezesizwe. Lezi zindinganiso zichaza ukwakheka kwamakhemikhali, izakhiwo zemishini, ukubekezelelana kobukhulu, kanye nezindlela zokuhlola ezidingekayo ukuqinisekisa ikhwalithi yomkhiqizo kanye nokusebenza okulinganayo. Ezinye zezindinganiso ezilandelwa kakhulu zifaka:
● I-ASTM A312 / A312M
Izinga le-ASTM A312 lihlanganisa amapayipi ensimbi engagqwali angenamthungo, ahlanganisiwe ngomthungo oqondile, kanye namapayipi ensimbi angagqwali asebenza kakhulu aklanyelwe isevisi yokushisa okuphezulu kanye nokugqwala okuvamile. Lisetshenziswa kabanzi ezimbonini ze-petrochemical kanye nezimboni zokukhiqiza ugesi.

● GB/T 14976
Lena indinganiso yaseShayina echaza amapayipi ensimbi engagqwali angenamthungo asetshenziselwa ukuthutha uketshezi. Igcizelela ukuhlanzeka nokumelana nokugqwala ezimbonini zokudla, zamakhemikhali kanye nezemithi.
● EN 10216-5
Indinganiso yaseYurophu ehlanganisa amashubhu ensimbi engagqwali angenamthungo ngezinjongo zokucindezela. Isebenza kumapayipi okushisa okuphezulu kanye nokucindezela okuphezulu ezinhlelweni zamandla nezemishini.
● I-JIS G3459
Le nqubo yaseJapan ihlobene namapayipi ensimbi engagqwali okusebenzisa amapayipi avamile. Ivame ukusetshenziswa ezinhlelweni zezimboni kanye nezomasipala.

Lezi zindinganiso aziqinisekisi nje kuphela ukunemba kobukhulu kodwa futhi nokufana kokumelana nokugqwala, amandla okunamathela, kanye nokumelana namazinga okushisa aphezulu, okwenza amapayipi afanele ukusetshenziswa okubalulekile.
Ububanzi Bokusetshenziswa Kwamapayipi Angenamthungo Ensimbi Engagqwali
1. Imboni Kawoyela Negesi
Amapayipi angenasici angenamthungo abalulekile emisebenzini ephezulu, ephakathi, kanye neyaphansi. Kusukela kumapulatifomu okubhoboza kuya ezindaweni zokuhluza, la mapayipi aphatha ukucindezeleka okukhulu kanye nezindawo ezigqwalisayo ngokunakekelwa okuncane.
• Kusetshenziswa emipayipini engaphansi kolwandle, ekuthuthweni kwamafutha, kanye nasezintanjeni zokujova ngamakhemikhali.
• Amazinga afana ne-316L kanye ne-904L anikeza ukumelana okuphezulu kwe-chloride.

2. Izitshalo Zamakhemikhali Namakhemikhali
Amapayipi angenasici angenamthungo athwala izinto ezibola kakhulu njenge-sulfuric acid, ama-chloride, kanye namakhemikhali ane-pH ephezulu. Amazinga afana ne-304, 316L, kanye ne-310S ayathandwa ngenxa yokungangeni kwawo kwamakhemikhali kanye nokumelana nokushisa.
• Isetshenziswa kuma-heat exchanger, kuma-reactor, kanye namakholomu okucwilisa.
• Akukho mthungo wokushisela = izindawo ezibuthakathaka ezimbalwa ngaphansi kokucindezeleka noma ukugqwala.
3. Ukukhiqizwa Kwamandla Nokushintshanisa Ukushisa
Ezinhlelweni zokushisa okuphezulu njengezitshalo zamandla enuzi, ezishisayo, kanye nelanga, amapayipi ensimbi engagqwali asebenza ngaphansi kokujikeleza kokushisa kanye nemidiya enamandla. Ukuhambisana ne-ASTM A213 kanye ne-EN 10216-5 kuqinisekisa ukusimama kokucindezela okuphezulu kanye nokushisa.
• Kufanelekela amapayipi ebhoyila, amapayipi okuvuselela ukushisa, kanye nezinhlelo zokupholisa umoya.
• Insimbi engagqwali engu-310S iphumelela kakhulu ezindaweni ezivame ukungcoliswa yi-oxidation.

4. Izimboni Zokudla Nezemithi
Ukuhlanzeka kubalulekile kulezi zimboni. Amapayipi angenasici angenamthungo aqeda ukungcola kwe-weld, aqinisekise ukuthi izindawo zangaphakathi zibushelelezi futhi ziyamelana nokungcoliswa yizinto eziphilayo.
• Izicelo zifaka phakathi imishini yobisi, imigqa yokucubungula iziphuzo, kanye nokukhiqizwa kwemithi.
• Izindinganiso ezifana ne-GB/T 14976 kanye ne-ASTM A270 zivame ukubhekiselwa kuzo.

5. Ubunjiniyela Bezolwandle
Umkhakha wasolwandle udinga izixazululo eziqinile zamapayipi ukuze kulwiwe nokugqwala okunamandla kwamanzi anosawoti. Amapayipi angenamthungo ensimbi engagqwali, ikakhulukazi ama-duplex nama-904L, ahlinzeka ngokusebenza kwesikhathi eside ezindaweni ezingaphansi kwamanzi kanye nezindawo ezimanzi.
• Izinhlelo zokusebenza zifaka phakathi izinhlelo ze-ballast, amayunithi okususa usawoti emanzini, kanye namapulatifomu asogwini lolwandle.
6. Ubunjiniyela Bokwakha Nokwakha
Izinhlaka zokwakha nezakhiwo ziya ngokuya zifaka insimbi engagqwali ngezinjongo zamandla kanye nobuhle. Amapayipi angenamthungo akhethwa ukuze asetshenziswe ekuthwaleni umthwalo, izibambo, kanye nezindonga zamakhethini ngenxa yemigqa yawo ehlanzekile kanye nokumelana nokugqwala.

Kungani Kufanele Sikhethe Amapayipi Angenamthungo Ensimbi Engagqwali?
I-Sakysteel inikeza uhlu oluphelele lwamapayipi ensimbi engagqwali angenamthungo ahlukahlukene ngamamaki nobukhulu obuhlukahlukene, wonke ahambisana nezindinganiso ezinkulu zomhlaba wonke. Ngemishini yokukhiqiza ethuthukisiwe kanye nokulawula ikhwalithi okuqinile, i-Sakysteel iqinisekisa:
• Ukubekezelelana okuqinile
• Ukuqedwa kwendawo okumangalisayo
• Ukumelana nokugqwala okuphezulu kanye nokucindezela
• Ukulethwa okusheshayo kanye nokukhiqizwa okwenziwe ngokwezifiso
Umkhiqizo ngamunye uhlolwa ngokucophelela okuhlanganisa ukuhlolwa kwe-PMI, ukuhlolwa kwe-hydrostatic, ukutholwa kwamaphutha e-ultrasonic, kanye nokuhlolwa kobukhulu.
