Ma nā ʻāpana paila, mea hoʻololi wela, ipu kaomi a me nā paipu hana petrochemical ma ʻEulopa a me ka honua holoʻokoʻa.EN 10216ʻo ia ke kūlana ʻEulopa i hoʻopili nui ʻia no nā paipu kila seamless no nā kumu kaomi. Ma waena o nā papa āpau,P235GHa meP265GH— ʻo nā papa wela kiʻekiʻe ʻelua ʻaʻole i hoʻohui ʻia — hāʻawi i ka hana like akā ua hoʻonohonoho pono ʻia. Hoʻopilikia pololei ke koho ʻana i ka papa hewa i ke kumukūʻai papahana a me ka palekana hana.
Ma ke ʻano he mea kūʻai aku ʻoihana o nā paipu kila ʻoihana, mālama ʻo SANONPIPE i kahi waihona piha o nā paipu seamless series EN 10216 e uhi ana i nā papa āpau ʻole-alloy a me nā alloy. Wehewehe kēia ʻatikala i nā ʻokoʻa koʻikoʻi ma waena o P235GH a me P265GH, a hōʻike i nā wahi nānā kūʻai koʻikoʻi e hāʻawi i ke alakaʻi koho maopopo no nā hui ʻenekinia a me nā hui kūʻai.
ʻIkepili o ke Kūlana EN 10216
EN 10216Nā paipu kila humuhumu ʻole no nā kumu kaomihe kūlana hoʻohui ʻEulopa e wehewehe ana i nā kūlana hoʻouna loea no nā paipu kaomi maʻemaʻe ma nā pae mahana like ʻole. Ua hoʻonohonoho ʻia i loko o kekahi mau ʻāpana:
- EN 10216-1Nā paipu kila ʻole-alloy me nā waiwai mahana lumi i kuhikuhi ʻia, nā pae maikaʻi TR1/TR2, no nā noi kaomi maʻamau
- EN 10216-2Nā paipu kila ʻole-alloy a me alloy no ka lawelawe wela kiʻekiʻe, papa maikaʻi GH, no nā paila, nā mea hoʻololi wela a me nā noi wela kiʻekiʻe
- EN 10216-3Nā paipu kila maikaʻi no ka lawelawe haʻahaʻa haʻahaʻa
- EN 10216-4Nā paipu kila metala
Nā māka GH(papa wela kiʻekiʻe) i hana ʻia no ka lawelawe wela kiʻekiʻe mau. Pono lākou i ka hoʻoheheʻe ʻana o ke kila i pepehi ʻia a me ka mālama wela maʻamau, me ka ikaika wela kiʻekiʻe i hōʻoia ʻia a me nā waiwai kolo, e lilo ana lākou i koho maʻamau no nā paipu paila, nā paipu hoʻololi a me nā pūpū ipu kaomi.
Hoʻohālikelike Papa Koʻikoʻi: P235GH vs P265GH
ʻO P235GH a me P265GH he mau papa wela kiʻekiʻe ʻaʻole i hoʻohui ʻia ma lalo o EN 10216-2. Hōʻike nā helu i ka ikaika hua liʻiliʻi loa ma MPa. Hōʻike nā papa ʻelua i nā gradients maopopo i ka kemika, ka hana a me ka hoʻohana.
1. Hoʻohālikelike ʻana i ka Hoʻohui Kemika
| ʻElemene | Palena P235GH | Palena P265GH | ʻOkoʻa koʻikoʻi |
|---|---|---|---|
| Kalapona (C) | ≤0.16% | ≤0.20% | ʻO ke kalapona kiʻekiʻe ma P265GH e hāʻawi i ka ikaika kiʻekiʻe akā emi iki ka hiki ke hoʻopili ʻia |
| Silika (Si) | ≤0.35% | ≤0.40% | Ua make loa nā mea ʻelua; ʻoi aku ka kiʻekiʻe o ka Si ma P265GH e hoʻomaikaʻi i ke kūpaʻa ʻana i ka oxidation wela kiʻekiʻe |
| Manganese (Mn) | ≤1.20% | ≤1.40% | Hoʻonui ka Mn kiʻekiʻe ma P265GH i ka ikaika ma o ka hoʻoikaika ʻana i ka hopena paʻa |
| Phosphorus / Sulfur (P/S) | ≤0.025% / ≤0.010% | ≤0.025% / ≤0.010% | ʻO nā palena koena paʻa ma nā papa ʻelua e hōʻoia i ka paʻakikī o ke kiʻekiʻe o ka mahana a me ke kūpaʻa ʻana o ka huhū |
| Nā Koena (Cr+Cu+Mo+Ni) | ≤0.70% | ≤0.70% | Ka mana koena i hoʻohui ʻia no ka maikaʻi o nā mea like ʻole |
2. Hoʻohālikelike ʻana i nā ʻano mīkini (Mahana o ka lumi, t ≤ 16 mm)
| Waiwai | P235GH | P265GH | Hopena ma ka noi |
|---|---|---|---|
| Ka ikaika hāʻawi liʻiliʻi loa | 235 MPa | 265 MPa | Hāʻawi ʻo P265GH i ka ~13% kiʻekiʻe aʻe o ka hua, e hiki ai ke hoʻolālā paia lahilahi ma ke kaomi like |
| Ka Pae Ikaika Tensile | 360 – 500 MPa | 410 – 570 MPa | Loaʻa iā P265GH kahi kāʻei ikaika i hoʻoneʻe ʻia i luna me ka palena palekana nui aʻe |
| Ka lōʻihi iki | 25% | 23% | Hāʻawi ʻo P235GH i ka ductility maikaʻi no ke kūlou anu, ka hoʻonui ʻana a me ka hana ʻana i ka paipu |
| Ka hopena Charpy liʻiliʻi ma 0°C | 27 J | 27 J | ʻO ka paʻakikī haʻahaʻa haʻahaʻa like, ua hoʻokō lāua ʻelua i nā koi hopena paila maʻamau |
| Ka Mahana Hana Hoʻomau Loa | ~400°C | ~425°C | Mālama ʻo P265GH i ka ikaika ma ka mahana metala kiʻekiʻe o ~25°C |
3. Nā Kūlana Noi a me ke Alakaʻi Koho
| Ana | Makemake ʻoe iā P235GH | Makemake ʻoe iā P265GH |
|---|---|---|
| Mahana Hana | ≤400°C nā paila wela haʻahaʻa a waena, nā mea hoʻololi haʻahaʻa | 400–425°C lawelawe mahana waena-kiʻekiʻe, nā laina mahu nui me ke kaomi waena |
| Pae Kaomi | Nā ʻōnaehana kaomi haʻahaʻa a waena, nā paipu kōkua | Nā paipu nui o ke kaomi waena-kiʻekiʻe, nā pūpū a me nā poʻomanaʻo o nā ipu kaomi |
| Hana ʻana | Nā pūʻolo paipu e koi ana i ke kūlou anu nui, ka hoʻonui ʻana a i ʻole ka lapalapa ʻana | ʻO ka hapa nui o nā holo wili pololei kahi i hoʻoikaika ʻia ai ka ikaika |
| Kālele Kumukūʻai | Nā papahana laulā e hoʻokau mua ana i ka pono o ke kumukūʻai | Nā papahana palena kiʻekiʻe e hoʻokau mua ana i ka ikaika a me ka palena palekana |
| Nā Hoʻohana Maʻamau | Nā paia wai paila, nā paipu economizer, nā pūʻolo hoʻololi wela haʻahaʻa | Nā ʻāpana superheater paila, nā poʻomanaʻo mahu nui, nā paipu hana kaomi waena petrochemical |
Rula koho koʻikoʻi: E koho iā P235GH no nā mahana ≤400°C a me nā koi hoʻokumu kiʻekiʻe; e koho iā P265GH no ke kaomi kiʻekiʻe, ka mahana kiʻekiʻe a me ke kūkulu ʻana i hoʻopaʻa mua ʻia. ʻO ka ʻokoʻa kumukūʻai ma kahi o 5-8%, a pono e loiloi pū ʻia me ka hoʻonui ʻana i ka mānoanoa o ka paia.
Hoʻolauna Pōkole i nā Papa Maʻamau ʻē aʻe
Nā Papa Mahana Kiʻekiʻe ʻAʻole Alloy
- P195GH: Papa wela kiʻekiʻe pae komo me ka ikaika hua 195 MPa. ʻO ke ʻano hana maikaʻi loa, hoʻohana ʻia no nā paipu kōkua paila haʻahaʻa a me nā paipu uahi; koho kumukūʻai haʻahaʻa loa.
- P355GHPapa ʻole-alloy ikaika kiʻekiʻe me ka ikaika hua 355 MPa. No nā ipu kaomi paia kaumaha a me nā poʻomanaʻo paila anawaena nui; koho ʻē aʻe i hoʻonui ʻia i ka P265GH.
Nā Papa Mahana Kiʻekiʻe Alloy
- 16Mo3ʻO ke kila Molybdenum-alloy me ke kūpaʻa hydrogen hoʻouka maikaʻi loa a me ka hana kolo. Hoʻohana ʻia i nā ʻāpana hydroprocessing refinery a me nā paila kaomi kiʻekiʻe; lawelawe kiʻekiʻe ~500°C.
- 13CrMo4-5: 1.25Cr-0.5Mo kila chrome-moly, like me ASTM P11. He mea maʻamau i ka hana hydroprocessing wela waena a me ka lawelawe sulfidic.
- 10CrMo9-10: 2.25Cr-1Mo kila chrome-moly, like me ASTM P22. ʻOi aku ka maikaʻi o ke kūpale kolo; kūlana ʻoihana no nā laina mahu nui o ka hale hana mana.
Nā Manaʻo Kūʻai Koʻikoʻi
1. E wehewehe pono i ka ʻāpana maʻamau a me ka papa maikaʻi
E haʻi mau i ka inoa piha e like meEN 10216-2 P235GH, ʻaʻole wale ka inoa papa. Pono e pepehi piha ʻia nā papa GH a hoʻomaʻamaʻa ʻia (+N). ʻAʻole loa e pani ʻia nā papa TR (mahana lumi) no ka lawelawe GH.
2. Mānoanoa o ka paia a me nā ʻae ʻana o ka ana
ʻO ke ahonui pā paʻamau EN 10216+12.5% / -10%No nā papahana kikoʻī kiʻekiʻe, hiki ke ʻaelike ʻia ke ahonui T2 (±10%). No nā paipu paia kaumaha me ke anawaena nui, e kuhikuhi i nā koi poepoe ʻole e pale aku i nā pilikia hoʻokomo ma kahi.
3. Nānā & Hoʻāʻo ʻAʻole Luku
- He mea koi ʻia ka hoʻāʻo hydrostatic e like me ke kūlana, ma nā waiwai kaomi i kuhikuhi ʻia a i ʻaelike ʻia paha.
- No ka lawelawe paila a me ka ipu kaomi,hoʻāʻo ultrasonic (UT)ua ʻōlelo ʻia e ʻike i nā laminations kūloko a me nā māwae.
- No nā pūʻolo paipu hoʻololi wela,ka hoʻāʻo ʻana o ke au eddy (ET)ua ʻōlelo ʻia no ka ʻike ʻana i nā kīnā ma ka ʻili a me kahi kokoke i ka ʻili.
4. Palapala Kūlana a me ka Hiki ke Hahai ʻia
Pono e hoʻolako ʻia kēlā me kēia pūʻulu meEN 10204 3.1 Nā Palapala Ho'āʻo Mille uhi ana i ka helu wela, ka haku mele kemika, nā waiwai mechanical, nā moʻolelo mālama wela a me nā hōʻike nānā. No nā papahana EU a i ʻole nā noi PED (Pressure Equipment Directive), e hōʻoia i ka hiki ke hahai ʻia a me ka mana o ka palapala hōʻoia.
5. E hōʻoia i ke kūlana hoʻouna
Loaʻa nā papa GH ma kai hoʻonohonoho ʻia (+N)kūlana ma ka paʻamau. No nā koi pā kaumaha a ikaika paha, hiki ke ʻaelike ʻia ka normalized a me ka tempered (+NT). E hōʻoia i ka pae paʻakikī ma ka loaʻa ʻana e hōʻoia i ka hana pono ʻana o ka mālama wela.
6. E hōʻoia i ka hana mahana kiʻekiʻe
No ka lawelawe wela kiʻekiʻe lōʻihi koʻikoʻi, e noika ikaika hua wela kiʻekiʻe or ʻikepili haki koʻikoʻimai ka mea wili — ʻaʻole wale nā waiwai mahana o ka lumi — e hōʻoia i ka hiki ke lawe i ka ukana ma ka mahana hoʻolālā.
Hopena
ʻO P235GH a me P265GH ma lalo o EN 10216-2 ke kumu kūpono no nā ʻōnaehana kaomi waena-kaomi waena: Hoʻohālikelike ʻo P235GH i ke ʻano a me ka hoʻokele waiwai ma ke ʻano he lio hana no nā pūʻolo exchanger laulā a me nā paipu paila; Hāʻawi ʻo P265GH i ka ikaika kiʻekiʻe a me ka hiki ke mahana no nā mains a me nā poʻomanaʻo kaomi waena. ʻO ka hoʻohālikelike pololei ʻana i ka papa a me ka kaohi maikaʻi o ke kūʻai ʻana he mea nui ia no ka hana palekana lōʻihi o nā ʻōnaehana kaomi wela kiʻekiʻe.
Loaʻa iā SANONPIPE ka laina paipu seamless EN 10216 piha, mai nā ʻano paipu ʻole P195GH / P235GH / P265GH a i nā ʻano paipu chrome-moly. Me nā palapala piha 3.1 a me nā lawelawe NDT i hana ʻia, hāʻawi mākou i ka lako pane wikiwiki no nā ʻoihana paila, petrochemical a me nā ipu kaomi.
No nā papa inoa kikoʻī o nā waihona, nā ʻōlelo kūʻai a i ʻole ke kākoʻo koho papa loea, e kelepona i kā mākou hui kūʻai aku.
