I. Chuma ndi chiyaniAPI5L
1. API5L-B payipi zitsulo, lofanana L245 mtundu Wuyang Chitsulo ndi zitsulo, L245 wa otsika aloyi mndandanda, mtengo ndi mkulu, mtengo wa zipangizo zosiyanasiyana si yemweyo, makamaka ntchito mapaipi mafuta, mapaipi zachilengedwe, etc., ndi otsika kuthamanga madzi koyilo chitoliro, ntchito yake ndi 20 # msoko chitoliro pafupifupi.
2. Zinthu zake ndix52 gawo pipeline zitsulo chitoliroline zitsulo, amene ndi mtundu wa zitsulo ndi zofunika zapadera ntchito potengera mafuta ndi gasi mapaipi.Malinga ndi makulidwe ndi mapangidwe wotsatira, akhoza kupangidwa ndi otentha mosalekeza anagubuduza mphero, ng'anjo Kugubuduza mphero kapena sing'anga wandiweyani mbale mphero ndipo anapanga lalikulu m'mimba mwake zitsulo chitoliro ndi kuwotcherera kozungulira kapena UOE molunjika msoko kuwotcherera.
3. Chitoliro chopanda msoko kapena chowotcherera, muyezo ndiAPI 5L(paipi yapaipi) PSL2ndi imodzi mwa magiredi, ina ndi PSL1 poyerekeza, zofunika PSL2 ndi apamwamba kuposa PSL1API 5L ndi payipi mfundo chitoliro opangidwa ndi American Petroleum Institute, B ndi imodzi mwa kalasi payipi zitsulo.
II.API5L muyezo
1.API5L muyezo, kuchuluka kwa zolumikizira zitsulo PIPE ndi PIPE WLD 10" SCH STD API5L ASTM A106 GRB chitoliro chosasunthika chachitsulo m'gawo lomwelo sichidzapitilira 50% ya kuchuluka kwa mapaipi. yeretsani mabowo a kubowola kapena mpweya wothamanga kwambiri kuti muchotse zipsera m'mabowo.
2. Cr:≤025 Nickel Ni:≤030 Copper Cu:≤025 Mechanical properties: Mphamvu yolimba ya sigma b (MPa): 560 (57) kapena mphamvu zokolola zapamwamba sigma s (MPa) : 335 (34) kapena elongation delta yapamwamba (%) : kuchepetsa kukula kwa malo a 18 bits (%) : 45 kapena mphamvu zowonjezera zowonjezera Akv (J) : 55 kapena kuwonjezereka kwamphamvu kwa ma alpha kv (J/cm2).
3.API 5L muyezo chimakwirira zofunika kupanga payipi zitsulo, makamaka kumakoka mphamvu, zokolola mphamvu, chipinda kutentha zimakhudza toughness, elongation pa yopuma, etc. Malinga ndi mitundu ya payipi zitsulo, API 5L lagawidwa mu chitoliro ambiri zitsulo ndi wapadera. Chitoliro chachitsulo, chomwe chitoliro chachitsulo chimagawidwa mu chitoliro chachitsulo chachitsulo ndi chitoliro chachitsulo champhamvu, API 5L muyezo umakhudzanso zofunikira za kupanga zitsulo zazitsulo.
III, zinthu za API5Lgrb ndi chiyani
1. API 5LGRB ndi yopanda msoko kapenawelded zitsulo chitoliro, muyezo ndi API 5L (petroleum pipeline pipeline), PSL2 ndi imodzi mwa milingo, mlingo wina ndi PSL1 poyerekeza, zofunika PSL2 ndi apamwamba kuposa PSL1API 5L ndi mfundo mapaipi opangidwa ndi American Petroleum Institute, B ndi mtundu wa kalasi ya pipeline steel.
2.ASME SA517, ASTM A517 chotengera chopondereza Chozimitsidwa ndi kutenthetsa mbale yachitsulo yamphamvu kwambiri ASME SA517/SA517M yokhazikika imaphatikizapo: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrG7 SA517GrF, SA517GrG7, SA517GrG7 SA5;Muyezo wa ASTM A517/A517M umaphatikizapo: A517GrA,.
3. PerekaniAPI 5L PSL2muyezochitoliro chachitsulo chozunguliraGrB-X70 Outer diameter 219-3650 mm Moni, takhala tikupanga chitoliro chozungulira kwa zaka 24, tikuyembekeza kukhala ndi mwayi wogwirizana nanu.
