I. Iyini impahlaI-API5L
1. Insimbi yepayipi ye-API5L-B, elingana ne-L245 brand Wuyang Iron nensimbi, L245 ingeyochungechunge lwe-alloy ephansi, intengo iphakeme kakhulu, intengo yezinto ezihlukene ayifani, ikakhulukazi esetshenziselwa amapayipi kawoyela, amapayipi emvelo, njll., iyipayipi lekhoyili elinomfutho ophansi, ukusebenza kwalo kanye nepayipi elingenamthungo elingu-20# cishe.
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 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 lamalunga epayipi lensimbi 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 lamapayipi kufanele lishanele futhi Hlanza izimbobo zokubhoboza noma umoya womfutho ophezulu ukuze ukhiphe udoti emigodini Qinisekisa ukuthi indawo yokuvula imbobo (imbobo akufanele ibe ngaphansi kuka-127cm) ihlangabezana nezidingo futhi ivimbele ukuxhuma imbobo.
2. Cr:≤025 Nickel Ni:≤030 Copper Cu:≤025 Izakhiwo zikagesi: Amandla aqinile we-sigma b (MPa) : 560 (57) noma amandla esivuno esiphezulu sigma s (MPa) : 335 (34) noma i-delta ye-elongation ephakeme (%) : ukuncishiswa kwe-acuity yendawo yamabhithi angu-18 (%) : 45 noma ngaphezulu kwamandla omthelela we-Akv (J) : 55 noma amanani wokuqina womthelela aphezulu we-alpha kv (J/cm2).
Izinga le-3.API 5L lihlanganisa izidingo zokukhiqizwa kwensimbi yepayipi, ikakhulukazi amandla aqinile, amandla okukhiqiza, ukuqina komthelela wezinga lokushisa kwegumbi, ukuphakama ngesikhathi sekhefu, njll. Ngokwezinhlobo zensimbi yepayipi, i-API 5L ihlukaniswe ipayipi lensimbi elijwayelekile futhi elikhethekile. ipayipi lensimbi, lapho ipayipi lensimbi elijwayelekile lihlukaniswe ipayipi lensimbi elijwayelekile kanye nepayipi lensimbi elinamandla aphezulu, izinga le-API 5L lihlanganisa nezidingo zenqubo yokukhiqiza yensimbi yamapayipi.
III, yini impahla ye-API5Lgrb
1. I-API 5LGRB ayinamthungo nomaipayipi lensimbi elishiselwe, izinga yi-API 5L(ipayipi lepayipi likaphethiloli), i-PSL2 ingelinye lamazinga, elinye izinga yi-PSL1 uma kuqhathaniswa, izidingo ze-PSL2 ziphakeme kune-PSL1API 5L ukucaciswa kwepayipi lepayipi elakhiwe yi-American Petroleum Institute, B iwuhlobo wezinga 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.
