I. Yintoni impahlaAPI5L
1. I-API5L-B yentsimbi yombhobho, elingana ne-L245 brand Wuyang Iron kunye nentsimbi, i-L245 iyinxalenye ye-alloy series ephantsi, ixabiso liphezulu kakhulu, ixabiso lezinto ezahlukeneyo azifani, ikakhulukazi ezisetyenziselwa imibhobho yeoli, imibhobho yendalo, njl., ngumbhobho wekhoyili woxinzelelo oluphantsi, ukusebenza kwawo kunye ne-20# ingenamthungo umbhobho phantse.
2. Izinto eziphathekayoX52 ibakala umbhobho wentsimbi umbhobhoumgca wensimbi, oluhlobo lwentsimbi oluneemfuno ezizodwa ezisetyenziselwa ukuhambisa ioli kunye nemibhobho yegesi yendalo.Ngokobunzima kunye nokwakheka okulandelayo, inokuveliswa ngelitye lokusila eliqhubekayo elishushu, ilitye lokusila okanye ipleyiti eshinyeneyo ephakathi kwaye yenziwe ibe ngumbhobho wentsimbi odayamitha omkhulu ngokuwelda okujikelezayo okanye i-UOE yokuwelda umthungo othe ngqo.
3. Umbhobho wensimbi ongenamthungo okanye odibeneyo, umgangatho unjaloAPI 5L(umbhobho wombhobho) PSL2lelinye lamabakala, elinye yiPSL1 xa kuthelekiswa, iimfuno zePSL2 ziphezulu kunePSL1API 5L yinkcazo yombhobho owenziwe yiAmerican Petroleum Institute, B lelinye lamabakala entsimbi yombhobho.
II.API5L umgangatho
Umgangatho we-1.API5L, inani lemibhobho yentsimbi ye-PIPE kunye ne-PIPE WLD 10 "SCH STD API5L ASTM A106 GRB ipayipi yensimbi engenamthungo kwicandelo elifanayo aliyi kudlula i-50% yenani lemibhobho. coca imingxuma yokubhora okanye yomoya woxinzelelo oluphezulu ukususa umgquba kwimingxuma.
2. Cr:≤025 Nickel Ni:≤030 Copper Cu:≤025 Iipropati zeMechanical: Amandla e-Tensile ye-sigma b (MPa) : 560 (57) okanye isivuno esiphezulu samandla sigma s (MPa) : 335 (34) okanye i-delta yobude obuphezulu (%) : ukucutha ubukhali bendawo yeebhithi ezili-18 (%) : 45 okanye ngaphezulu kwamandla empembelelo Akv (J) : 55 okanye amaxabiso aphezulu empembelelo yokuqina kwe-alpha kv (J/cm2).
Umgangatho we-3.API 5L ugubungela iimfuno zemveliso yentsimbi yombhobho, ngakumbi amandla okuqina, amandla esivuno, ukuqina kwefuthe lobushushu begumbi, ukunwenwa ngexesha lekhefu, njl.njl. Ngokweentlobo zentsimbi yombhobho, i-API 5L yahlulwe yaba ngumbhobho wentsimbi jikelele kunye nokhethekileyo. umbhobho wentsimbi, phakathi apho umbhobho wentsimbi ngokubanzi wahlulwe kumbhobho wentsimbi oqhelekileyo kunye nombhobho wentsimbi onamandla aphezulu, umgangatho we-API 5L uquka iimfuno zenkqubo yokuvelisa intsimbi yombhobho.
III, yintoni impahla ye-API5Lgrb
1. I-API 5LGRB ayinamthungo okanyeumbhobho wentsimbi odityanisiweyo, umgangatho yi-API 5L(umbhobho wepetroleum wepetroleum), iPSL2 yenye yamanqanaba, elinye inqanaba yiPSL1 xa kuthelekiswa, iimfuno zePSL2 ziphezulu kunePSL1API 5L luphawu lombhobho ophuhliswe yiAmerican Petroleum Institute, B luhlobo yomgangatho wentsimbi yombhobho.
I-2.ASME SA517, i-ASTM A517 isitya soxinzelelo Ucinywe kwaye unomsindo ophezulu we-alloy plate yensimbi ye-ASME SA517 / SA517M umgangatho uquka: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrG7 SA517GrF, SA517GrG7, SA517GrF, SA517GrE5;Umgangatho we-ASTM A517/A517M uquka: A517GrA,.
3. UboneleloAPI 5L PSL2umgangathoumbhobho wentsimbi ejikelezayoI-GrB-X70 Idayamitha yangaphandle 219-3650 mm Molo, sivelisa umbhobho ojikelezayo iminyaka engama-24, sinethemba lokuba nethuba lokusebenzisana nawe.
