I-API 5L X42, eyaziwa nangokuthi i-L290, uhlobo lwepayipi lomugqa elisetshenziswa embonini kawoyela negesi.
Izakhiwo zezinto ezibonakalayo ziyi-amandla amancane okukhiqiza angu-42,100 psi(290 MPa) kanye ne-aamandla amancane okudonsa angu-60,200 psi(415 MPa). Iphakeme ngebanga elilodwa kune-API 5L Grade B futhi ifaneleka ezinhlelweni zokusebenza ezinamandla aphakathi.
I-X42 ivame ukukhiqizwa nge-Seamless, SSAW, LSAW, kanye ne-ERW. Izimbozo kanye nokuqedwa kuyatholakala ukuze kuhlangatshezwane nezidingo ezithile zohlelo lokusebenza.
Izimo Zokulethwa
Kuye ngezimo zokulethwa kanye nezinga le-PSL, ingahlukaniswa kanje:
I-PSL1: X42 noma i-L290;
I-PSL2: X42R, X42N, X42Q, X42M noma i-L290R, L290N, L290Q, L290M;
Izinhlamvu zesijobelelo se-PSL2 ngasinye simelela ukwelashwa kokushisa okuhlukile.
R: Kugoqiwe;
N: Ukulungisa;
Q: Kucinyiwe futhi kuthambile;
M: Ukwelashwa nge-thermo-mechanical.
Inqubo Yokukhiqiza
I-X42 ivumela inqubo elandelayo yokukhiqiza:
Uma ukuthola kunzima ukuqonda lezi zifinyezo, hlola ukuhlanganiswa kwethu kwezihloko eziphatheleneizifinyezo ezivamile zamapayipi ensimbi.
I-Botop Steel ingakunikeza ububanzi bosayizi bamapayipi njengoba kuboniswe kuthebula elingezansi.

Ukwakheka Kwamakhemikhali kwe-API 5L X42
Ukwakheka Kwamakhemikhali Kwepayipi Le-PSL 1 elino-t ≤ 25.0 mm (0.984 in.)
Ukwakheka Kwamakhemikhali Kwepayipi Le-PSL 2 elino-t ≤ 25.0 mm (0.984 in.)
Kwemikhiqizo yepayipi lensimbi ye-PSL2 ehlaziywe ngeokuqukethwe kwekhabhoni okungu-≤0.12%, i-CE elingana nekhabhonii-pcmingabalwa kusetshenziswa ifomula elandelayo:
CEi-pcm= C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/15 + 5B
Kwemikhiqizo yepayipi lensimbi ye-PSL2 ehlaziywe ngeokuqukethwe kwekhabhoni > 0.12%, i-CE elingana nekhabhonillwingabalwa kusetshenziswa ifomula engezansi:
CEllw= C + Mn/6 + (Cr + Mo + V)/5 + (Ni +Cu)/15
Ukwakheka Kwamakhemikhali okune-t ＞ 25.0 mm (0.984 in.)
Lokhu kungaxoxwa ngakho ngokubhekisela ekwakhiweni kwamakhemikhali ngenhla.
Izakhiwo Zemishini ze-API 5L X42
Izakhiwo Zokunamathela
Ukuhlolwa kokudonsa kuyisilingo esibalulekile sezakhiwo zemishini zamashubhu ensimbi, ezikwazi ukukala amandla okukhiqiza, amandla okudonsa, kanye nemingcele ebalulekile yokwelula.
Amandla okukhipha i-X42 angama-42,100 psi noma ama-290 MPa.

Izakhiwo Zokunamathela ze-PSL1 X42
Izakhiwo Zokunamathela ze-PSL2 X42
Inothi: Izidingo zichazwe kabanzi esigabeni se-Mechanical Properties sikaI-API 5L X52, okungabukwa ngokuchofoza ifonti eluhlaza okwesibhakabhaka uma unesithakazelo.
Ezinye Izivivinyo Zemishini
Ukuhlolwa Kokugoba
Ukuhlolwa Kokuthamba
Ukuhlolwa Kokugoba Okuqondiswayo
Ukuhlolwa Komthelela we-CVN kwe-PSL 2 Pipe
Ukuhlolwa kwe-DWT kwe-PSL 2 Welded Pipe
Vele, akuwona wonke amashubhu adinga ukuhlolwa ukuze athole isethi ephelele yezakhiwo zemishini, kodwa kunalokho ukuhlolwa kukhethwa ngokuya ngohlobo lweshubhu. Izidingo ezithile zingatholakala kuThebula 17 no-18 le-API 5L standard.
Ungasithinta futhi ukuze uthole lolu lwazi.
Ukuhlolwa Kwamanzi
Isikhathi Sokuhlolwa
Bonke osayizi bamashubhu ensimbi angenamthungo nashibiliwe ano-D ≤ 457 mm (18 in.):isikhathi sokuhlola ≥ 5s;
Ipayipi lensimbi elihlanganisiwe D > 457 mm (18 in.):isikhathi sokuhlola ≥ 10s.
Imvamisa Yokuhlola
Ipayipi ngalinye lensimbifuthi akufanele kube khona ukuvuza okuvela emzimbeni wokushisela noma wepayipi ngesikhathi sokuhlolwa.
Izingcindezi zokuhlola
Ingcindezi yokuhlola ye-hydrostatic P ye-aipayipi lensimbi elingenasicikungabalwa ngokusebenzisa ifomula.
P = 2St/D
Sukucindezeleka kwe-hoop. inani lilingana namandla amancane okukhiqiza acacisiwe ephesenti le-xa lepayipi lensimbi, ku-MPa (psi);
tukujiya kodonga okucacisiwe, okuvezwa ngamamilimitha (amasentimitha);
Dububanzi obungaphandle obucacisiwe, obuvezwa ngamamilimitha (amasentimitha).
Ukuhlolwa Okungonakalisi
Kwamashubhu e-SAW, izindlela ezimbili,UT(ukuhlolwa kwe-ultrasonic) nomaRT(ukuhlolwa kwe-radiography), kuvame ukusetshenziswa.
ET(ukuhlolwa kwe-electromagnetic) akusebenzi kumashubhu e-SAW.
Izithungo ezihlanganisiwe kumapayipi ahlanganisiwe asezingeni ≥ L210/A kanye nobubanzi ≥ 60.3 mm (2.375 in) kufanele zihlolwe ngaphandle kokubhujiswa ukuze zibone ukujiya nobude obugcwele (100%) njengoba kuchaziwe.
Ukuhlolwa kwe-UT okungonakalisi
Ukuhlolwa kwe-RT okungonakalisi
Wonke amashubhu angenamthungo e-PSL 2, kanye namashubhu angenamthungo acinyiwe futhi aqinisiwe e-PSL1 Grade B, kufanele ahlolwe ngokuphelele (100%) ngaphandle kokubhubhisa.
Inhlanganisela eyodwa noma inhlanganisela ye-ET (Ukuhlolwa Kwe-Electromagnetic), i-UT (Ukuhlolwa Kwe-Ultrasonic), kanye ne-MT (Ukuhlolwa Kwezinhlayiya Ze-Magnetic) ingasetshenziswa ku-NDT.
Ukubekezelelana Okulinganayo
Izidingo ze-API 5L zokubekezelelana okunezilinganiso zichazwe kabanzi kuI-API 5L Ibanga BUkuze ugweme ukuphindaphinda, ungachofoza ifonti eluhlaza okwesibhakabhaka ukuze ubuke imininingwane efanele.
Ishadi Leshejuli Yamapayipi e-API 5L
Ukuze kube lula ukuwabuka nokusebenzisa, sihlele amafayela e-PDF eshejuli afanele. Ungalanda futhi ubuke la madokhumenti uma kudingeka.
Ngaphezu kwalokho, i-API 5L icacisa ububanzi obuvunyelwe obucacisiwe bangaphandle kanye nobukhulu bodonga obucacisiwe.

Selokhu yasungulwa ngo-2014,Insimbi yeBotopisibe ngumhlinzeki ohamba phambili wamapayipi ensimbi yekhabhoni eNyakatho yeShayina, eyaziwa ngenkonzo enhle kakhulu, imikhiqizo esezingeni eliphezulu, kanye nezixazululo eziphelele.
Le nkampani inikeza amapayipi ahlukahlukene ensimbi yekhabhoni kanye nemikhiqizo ehlobene nayo, kufaka phakathi ipayipi lensimbi elingenamthungo, i-ERW, i-LSAW, kanye ne-SSAW, kanye nohlu oluphelele lwezihlanganisi zamapayipi nama-flange. Imikhiqizo yayo ekhethekile ifaka phakathi ama-alloy ebanga eliphezulu kanye nezinsimbi ezingagqwali ze-austenitic, ezenzelwe ukuhlangabezana nezidingo zamaphrojekthi ahlukahlukene amapayipi.
