I. Chuma ndi chiyaniAPI5L
1. API5L-B payipi zitsulo, lofanana L245 mtundu Wuyang Chitsulo ndi zitsulo, L245 wa mndandanda otsika aloyi, mtengo ndi mkulu, mtengo wa zinthu 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, chiwerengero cha olowa zitsulo PIPE ndi PIPE WLD 10 "SCH STD API5L ASTM A106 GRB seamless chitoliro chitoliro mu gawo lomwelo si upambana 50% ya chiwerengero cha mapaipi. Musanakhazikike, okhetsa chitoliro kusesa ndi kuyeretsa mabowo kubowola kapena kuthamanga kwambiri mpweya mu hole scum kuchotseratu hole scumum kuti achotse hoper. kukhala osachepera 127cm) amakwaniritsa zofunikira ndikuletsa kutsekeka kwa dzenje.
2. Cr:≤025 Nickel Ni:≤030 Copper Cu:≤025 Mechanical properties: Kulimba kwamphamvu kwa sigma b (MPa) : 560 (57) kapena mphamvu zokolola zapamwamba sigma s (MPa) : 335 (34) kapena elongation apamwamba a delta acuity 1% (8%) 45 kapena kupitilira mphamvu yamphamvu Akv (J) : 55 kapena kukhudzika kwamphamvu kwa alpha kv (J/cm2).
3.API 5L muyezo chimakwirira zofunika kupanga zitsulo payipi, makamaka kumakokedwa mphamvu, mphamvu zokolola, chipinda kutentha zimakhudza toughness, elongation pa yopuma, etc. Malinga ndi mitundu ya payipi zitsulo, API 5L lagawidwa mu chitoliro ambiri zitsulo ndi chitoliro chapadera zitsulo, mwa ambiri zitsulo chitoliro anawagawa chitoliro wamba zitsulo ndi mkulu mphamvu zitsulo chitoliro, API 5L muyezo komanso chimakwirira payipi zofunika ndondomeko kupanga zitsulo.
III, zinthu za API5Lgrb ndi chiyani
1. API 5LGRB ndi yopanda msoko kapenawelded zitsulo chitoliro, muyezo ndi API 5L (petroleum payipi chitoliro), 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 mapaipi zitsulo kalasi.
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.
