ʻO ka paila hao kalapona Seamless Medium a me nā paipu Superheat ASTM A210 maʻamau
| Kūlana:ASTM SA210 | Alloy a ʻAʻole: Carbon steel |
| Pūʻulu Papa: GrA. GrC | Noi: Paipu Boiler |
| Mānoanoa: 1 - 100 mm | Lapaʻau Surface: E like me ke koi o ka mea kūʻai aku |
| Ka Anawaena o waho (Ka puni): 10 - 1000 mm | ʻenehana: Huki ʻia ʻo Wela/Kukuʻi Anu |
| Ka lōʻihi: Paʻa ka lōʻihi a i ʻole ka lōʻihi like ʻole | Hoʻomaʻamaʻa wela: Annealing/normalizing |
| ʻAno ʻāpana: Poe | Pipe Kūikawā: Paipu Pā mānoanoa |
| Kahi i kumu: Kina | Hoʻohana: Boiler and Heat Exchanger |
| Palapala hōʻoia: ISO9001:2008 | Hoʻāʻo: ET/UT |
Hoʻohana nui ʻia ia e hana i ke kila carbon seamless kiʻekiʻe, no nā paipu boiler, nā paipu wela super
no ka ʻoihana bolier, paipu hoʻololi wela a me nā mea like ʻole me ka nui a me ka mānoanoa
Papa o ke kila boiler carbon kiʻekiʻe: GrA, GrC
| ʻElemu | Papa A | Papa C |
| C | ≤0.27 | ≤0.35 |
| Mn | ≤0.93 | 0.29-1.06 |
| P | ≤0.035 | ≤0.035 |
| S | ≤0.035 | ≤0.035 |
| Si | ≥ 0.1 | ≥ 0.1 |
A No kēlā me kēia hōʻemi o 0.01 % ma lalo o ke kalapona kiʻekiʻe i ʻōlelo ʻia, e ʻae ʻia ka piʻi ʻana o 0.06 % manganese ma luna o ka palena kiʻekiʻe a hiki i ka 1.35 %.
| Papa A | Papa C | |
| Ikaika U'i | ≥ 415 | ≥ 485 |
| Ka ikaika hua | ≥ 255 | ≥ 275 |
| Laki elongation | ≥ 30 | ≥ 30 |
Hōʻike Hydraustatic:
Pono e ho'āʻoʻia ka paipu kila me ka hydraulic hoʻokahi. ʻO 20 MPa ka piʻi kiʻekiʻe loa. Ma lalo o ke kaomi ho'āʻo, ʻaʻole i emi iho ka manawa hoʻokūpaʻa ma mua o 10 S, a ʻaʻole pono e kahe ka paipu kila.
Ma hope o ka ʻae ʻana o ka mea hoʻohana, hiki ke hoʻololi ʻia ka Hydraulic Test e ka Eddy Current Testing or Magnetic Flux Leakage Testing.
Ho'āʻo palahalaha:
ʻO nā paipu me ka anawaena waho i ʻoi aku ma mua o 22 mm e hoʻāʻo ʻia i ka hoʻāʻo ʻana. ʻAʻole ʻike ʻia ka Delamination, nā kiko keʻokeʻo, a i ʻole nā mea haumia i ka wā o ka hoʻokolohua holoʻokoʻa.
ʻO ka hoʻāʻo ʻana i ke ahi:
E like me nā koi o ka mea kūʻai aku a i ʻōlelo ʻia i loko o ka ʻaelike, hiki ke hana ʻia ka paipu kila me ka anawaena o waho ≤76mm a me ka mānoanoa o ka pā ≤8mm. Hana ʻia ka hoʻokolohua ma ka wela lumi me kahi lipi o 60 °. Ma hope o ke puhi ʻana, pono e hoʻokō ka wikiwiki o ke ahi o ka anawaena waho i nā koi o ka papa ma lalo nei, a ʻaʻole pono ka mea hoʻāʻo e hōʻike i nā māwae a i ʻole nā haehae.
Ho'āʻo paʻakikī:
E hana ʻia nā hoʻāʻo paʻakikī ʻo Brinell a i ʻole Rockwell ma nā specimens mai ʻelua paipu mai kēlā me kēia ʻāpana
