I. Iyini impahlaI-API5L
1. Insimbi yepayipi ye-API5L-B, elingana ne-L245 brand Wuyang Iron nensimbi, L245 ingeyochungechunge lwengxubevange ephansi, intengo iphakeme uma kuqhathaniswa, intengo yezinto ezihlukene ayifani, ikakhulukazi esetshenziselwa amapayipi kawoyela, amapayipi emvelo, njll., iyipayipi lekhoyili elinomfutho ophansi, ukusebenza kwalo kanye nepayipi elingenamthungo cishe elingu-20#.
2. IndabaX52 ibanga ipayipi lensimbi yepayipiinsimbi yomugqa, okuwuhlobo lwensimbi enezidingo ezikhethekile ezisetshenziselwa ukuhambisa amapayipi kawoyela negesi yemvelo. Ngokusho kobukhulu nokwakheka okwalandela, ingakhiqizwa umshini wokugaya oqhubekayo oshisayo, isigayo esigoqa isithando somlilo noma isigayo sepuleti esiwugqinsi futhi sakhiwe sibe yipayipi elikhulu lensimbi eliwububanzi ngokushisela okuvunguzayo noma i-UOE yokushisela umphetho oqondile.
3. Ipayipi lensimbi engenamthungo noma elishiselwe, izinga liwukuthiI-API 5L(ipayipi lepayipi) PSL2ingelinye lamabanga, elinye yi-PSL1 uma kuqhathaniswa, izidingo ze-PSL2 ziphakeme kune-PSL1API 5L iwukucaciswa kwepayipi lepayipi elakhiwe yi-American Petroleum Institute, B ingelinye lamabanga ensimbi yamapayipi.
II. I-API5L ejwayelekile
Okujwayelekile okungu-1.API5L, inani lamajoyinti ensimbi PIPE kanye ne-PIPE WLD 10" SCH STD API5L ASTM A106 GRB ipayipi lensimbi engenamthungo esigabeni esifanayo akufanele lidlule u-50% wenani lamapayipi. Ngaphambi kokufakwa, ishede lepayipi lizoshanela futhi lihlanze izimbobo zokubhoboza noma umoya womfutho ophezulu ukuze kukhishwe i-hoper scum. ibe ngaphansi kuka-127cm) ihlangabezana nezidingo futhi ivimbele ukuxhuma imbobo.
2. I-Cr:≤025 Nickel Ni:≤030 I-Copper Cu:≤025 Izakhiwo zikamshini: Amandla aqinile we-sigma b (MPa) : 560 (57) noma amandla esivuno esiphezulu sigma s (MPa) : 335 (34) noma ngaphezulu kwe-elongation acuity ye-1%) yendawo ye-delion engu-1 ye-delta (%) 45 noma ngaphezulu amandla omthelela we-Akv (J) : 55 noma amanani womthelela aphezulu omthelela we-alpha kv (J/cm2).
Izinga le-3.API 5L lihlanganisa izidingo zokukhiqiza zensimbi yepayipi, ikakhulukazi amandla aqinile, amandla okukhiqiza, ukuqina komthelela wegumbi lokushisa, ukuphakama ngesikhathi sekhefu, njll. Ngokusho kwezinhlobo zensimbi yepayipi, i-API 5L ihlukaniswe yaba ipayipi lensimbi elijwayelekile kanye nepayipi lensimbi ekhethekile, phakathi kwayo ipayipi lensimbi elijwayelekile lihlukaniswe ipayipi elivamile lensimbi namandla aphezulu ensimbi, i-API 5L ejwayelekile ihlanganisa nezidingo zenqubo yokukhiqiza insimbi.
III, yini impahla ye-API5Lgrb
1. I-API 5LGRB ayinamthungo nomaipayipi lensimbi elishiselwe, izinga yi-API 5L(ipayipi lephayiphi likaphethiloli), i-PSL2 ingelinye lamazinga, elinye izinga yi-PSL1 uma kuqhathaniswa, izimfuneko ze-PSL2 ziphakeme kune-PSL1API 5L ukucaciswa kwepayipi lepayipi elakhiwe yi-American Petroleum Institute, B iwuhlobo lwezinga lensimbi yamapayipi.
I-2.ASME SA517, i-ASTM A517 isitsha sokucindezela Isitsha sensimbi Esicishiwe futhi esishisayo esinamandla aphezulu ASME SA517/SA517M izinga lihlanganisa: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrG7G7 SA517GrG7, SA517GrG7, SA517GrG7, SA5; I-ASTM A517/A517M ejwayelekile ihlanganisa: A517GrA,.
3. UkuhlinzekaI-API 5L PSL2ejwayelekileipayipi lensimbi elivunguzayoI-GrB-X70 I-Outer diameter 219-3650 mm Sawubona, sesineminyaka engama-24 sikhiqiza ipayipi elivunguzayo, sithemba ukuthi sizoba nethuba lokubambisana nawe.
