I. He aha te rauemiAPI5L
1. Ko te paipa rino API5L-B, he rite ki te waitohu Wuyang Iron and steel L245, nō te raupapa koranu iti te L245, he tino teitei te utu, he rerekē te utu o ngā rauemi rerekē, e whakamahia ana mō ngā paipa hinu, ngā paipa taiao, me ētahi atu, he paipa koiri wai pēhanga iti, ko tana mahi he tata ki te 20# te kore hononga o ngā paipa.
2. Ko te rauemi heTaumata X52 paipa maitai paipaKo te maitai raina, he momo maitai me ngā whakaritenga motuhake e whakamahia ana mō te kawe i ngā paipa hinu me te hau māori. E ai ki te matotoru me te hanganga i muri mai, ka taea te whakaputa mā te mira hurihuri wera tonu, te mira hurihuri oumu, te mira pereti matotoru waenga rānei, ā, ka hangaia hei paipa maitai diameter nui mā te whakarewa porowhita, te whakarewa hononga tika UOE rānei.
3. Paipa maitai kore-tuitui, paipa whakarewa rānei, ko te paerewaAPI 5L (paipa paipa) PSL2Ko tētahi o ngā māka, ko tētahi ko PSL1 i te whakataurite, he teitei ake ngā whakaritenga PSL2 i te PSL1. Ko te API 5L te whakatakotoranga paipa i hangaia e te American Petroleum Institute, ko te B tētahi o ngā māka maitai paipa.
II. Paerewa API5L
1. E ai ki te paerewa API5L, kaua e neke atu i te 50% o te maha o ngā paipa te maha o ngā hononga o te PAIPA rino me te PAIPA WLD 10" SCH STD API5L ASTM A106 GRB paipa rino kore-hono i te wāhanga kotahi. I mua i te tāutanga, me horoi te whare paipa i ngā kōhao mai i te wiri, i te hau pēhanga teitei rānei hei tango i te paru i roto i ngā kōhao. Me whakarite kia tutuki i te kōhao (kaua e iti iho i te 127cm te kōhao) ngā whakaritenga, ā, kia kore ai e purua te kōhao.
2. Cr:≤025 Nikara Ni:≤030 Parahi Cu:≤025 Ngā āhuatanga miihini: Te kaha kume o te sigma b (MPa) : 560 (57) teitei ake rānei te kaha hua sigma s (MPa) : 335 (34) teitei ake rānei te delta whakaroa (%) : te whakaiti i te koi o te horahanga o te 18 moka (%) : te kaha pānga 45 teitei ake rānei Akv (J) : ngā uara pakari pānga 55 teitei ake rānei o te alpha kv (J/cm2).
3. Ka hipokina e te paerewa API 5L ngā whakaritenga whakaputa o te maitai paipa, inā koa mō te kaha kume, te kaha tuku, te pakari pānga pāmahana rūma, te roa i te whati, me ētahi atu. E ai ki ngā momo maitai paipa, ka wehea te API 5L ki ngā paipa maitai whānui me ngā paipa maitai motuhake, i roto i ēnei ka wehea te paipa maitai whānui ki ngā paipa maitai noa me ngā paipa maitai kaha teitei, ka hipokina hoki e te paerewa API 5L ngā whakaritenga tukanga whakaputa o te maitai paipa.
III, he aha te rauemi API5Lgrb
1. He maeneene te API 5LGRB,paipa maitai whakarewa, ko te paerewa ko te API 5L (paipa paipa hinu), ko te PSL2 tētahi o ngā taumata, ko te taumata kē ko te PSL1 hei whakataurite, he teitei ake ngā whakaritenga PSL2 i te PSL1. Ko te API 5L te whakatakotoranga paipa paipa i whakawhanakehia e te American Petroleum Institute, ko te B he momo paipa maitai.
2. ASME SA517, ASTM A517 ipu pēhanga Kua tineia, kua whakamaroketia hoki te pereti maitai koranu kaha teitei. Ko te paerewa ASME SA517/SA517M ko: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrF, SA517GrE, SA517GrQ; Ko te paerewa ASTM A517/A517M ko: A517GrA,.
3. TukungaAPI 5L PSL2paerewapaipa maitai porowhitaGrB-X70 Diameter o waho 219-3650 mm Kia ora, kua 24 tau mātou e hanga paipa porowhita ana, ko te tumanako ka whai wāhi mātou ki te mahi tahi me koe.
