Kana uchida kuziva rumwe ruzivo, senge mitengo, zvigadzirwa, mhinduro, nezvimwewo, prenditaura nesu online.
Tianjin Sanon Steel Pipe Co., Ltd. ikambani inotengesa zvinhu. Fekitori yedu yezvitoro iri muCangzhou City, Hebei Province. Nzvimbo huru yatinowana zvinhu ndeyemapaipi ebhoira, uye zvinhu zvinomiririra zviriASTM A335 P5/P11/P91/P92,ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. Zvinhu zvinomiririra mapaipi emapaipi ndeizviAPI 5L,API 5CT, zvinhu zvinomiririra mapaipi ekupwanya peturuGB/T 9948vari 15MoG/12CrMoVGGB/T 6479-2013 inomiririra zvinhu 10#/20#, machubhu ekuchinjana kupisa SA179/SA210/SA192, nezvimwewo, machubhu emakanika GB/T 8162 anomiririra zvinhu 10#/20#/Q345/42CrMo, EN10210 inomiririra zvinhu S355JOH/S355J2H, machubhu egasi silinda GB1 8248, inomiririra zvinhu 34CrMo4/30CrMo.
Mumunda wemapaipi esimbi yekabhoni, ASTM A500 Giredhi C uyeASTM A106 Giredhi Cndiyo miviri yezvinodiwa zvinhu zvinowanzo taurwa nezvayo. Kunyangwe zvese zviri simbi dzekabhoni uye zvakafanana ne "Giredhi C", zvakasiyana zvakanyanya muhuzivi hwekugadzira, maitiro ekugadzira, uye mamiriro ekushandisa. Chinyorwa chino chinopa kuenzanisa kwakadzama kubva pahukuru hwakasiyana, kusanganisira tsananguro dzakajairwa, kuumbwa kwemakemikari, hunhu hwemakanika, hunyanzvi hwehukuru, uye nharaunda dzinoshanda.
1. Tsananguro Yakajairika uye Mashandisirwo Akakosha
ASTM A500 - zita rakazaraMaitiro Akajairwa eMachubhu eSimbi yeCarbon Yakasungirirwa uye Isina Musono muMapombi neMaumbirwo AkatendereraSezvinoratidzwa nezita racho, iyi ndiyo nzira yekuisa machubhu ekuvaka, inoshanda kumachubhu ekuvaka esimbi yakasungirirwa uye isina musono yakatenderera, sikweya, rectangular, uye ane chimiro chakasarudzika. Inonyanya kushandiswa mukuvaka mafuremu, mabhiriji, nezvimwe zvivakwa zvekubatanidza zvakasungirirwa, zvakakotamiswa, kana zvakaboorwa. ASTM A500 inofukidza magiredhi A, B, C, uye D, neGiredhi C iriyo giredhi repamusoro-soro rinowanzoshandiswa.
ASTM A106 - zita rakazaraMaitiro Akajairwa ePaipi yeSimbi yeKabhoni Isina Musono Yebasa reKupisa Kwakanyanya. Uyu ndiwo mwero wepombi dzinoshandisa simba repamusoro-soro, unoshanda chete kumapombi esimbi yekabhoni isina musono, akagadzirirwa kutakura utsi, mvura, nezvimwe zvinoshandiswa mumamiriro ekunze ekupisa kwakanyanya uye kumanikidzwa kwakanyanya. ASTM A106 inosanganisira magiredhi A, B, naC, uye Giredhi C ndiyo ine simba repamusoro-soro.
Musiyano mukuru wemutsara mumwe chete: A500 Giredhi C ichubhu yekuvaka inotakura mutoro; A106 Giredhi C ipombi yekumanikidza yekufambisa mvura.
2. Maitiro Ekugadzira uye Mafomu Echigadzirwa
Mitemo miviri iyi yakasiyana zvikuru nenzira yekugadzira uye maumbirwo aripo:
| Chikamu | ASTM A500 Giredhi C | ASTM A106 Giredhi C |
|---|---|---|
| Kugadzira | Yakasungirirwa yakatonhora (ERW) kana isina musono | Isina musono chete (yapera kupisa kana kuti inotonhorera) |
| Maumbirwo | Zvikamu zvakatenderera, zvikweya, zvemakona mana, uye zvakakosha | Rakatenderera chete |
| Nzira yekuodha | Nedhayamita yekunze × ukobvu hwemadziro (OD × WT) | Nehukuru hwepombi (NPS) uye nhamba yehurongwa |
Kugona kweA500 kufukidza zvikamu zvina, zvina, nezvimwe zvisina kutenderera kunoratidza zvakananga nzvimbo yayo - "mumaRounds neMaumbirwo" - izvo A106 isina.
3. Dimensional Range
ASTM A500 Giredhi C: Inoshanda kumachubhu ane muganhu usingapfuure 2235 mm (88 in.) uye ukobvu hwemadziro husingapfuure 25.4 mm (1 in.). Saizi dzechubhu dzakaenzana dzinogona kusvika 22 in. × 22 in. Kushivirira ukobvu hwemadziro: ukobvu hwemadziro hwakayerwa hushoma hahufanirwe kuva pasi pe90% yeukobvu hwemadziro hwakatarwa.
ASTM A106 Giredhi C: Inoshanda kumapombi asina musono ane saizi dzemapombi dzakatarwa NPS ⅛ kusvika NPS 48 (DN 6 kusvika DN 1200), ane ukobvu hwemadziro zvichienderana neASME B36.10M (mashedhi 10 kusvika 160, XXH, nezvimwewo). Kushivirira ukobvu hwemadziro: ukobvu hwemadziro hwakayerwa hushoma hahufanirwe kuva pasi pe87.5% yeukobvu hwemadziro hwakatarwa.
4. Kuenzanisa Kuumbwa Kwemakemikari
Kusiyana kwemakemikari kunoratidza mashandiro akasiyana. A106 Giredhi C inoda silicon (Si ≥ 0.10%) kuti ivandudze kusimba kwekupisa uye kusimba kweoxidation, nepo A500 Giredhi C isina silicon inodiwa. A106 inoisawo miganhu yakasimba pakusvibiswa kunokuvadza senge phosphorus nesarufa kuti ive nechokwadi chekuti yakavimbika pasi pekupisa kwakanyanya uye kumanikidzwa kwakanyanya.
| Chikamu (chakanyanya, %) | ASTM A500 Giredhi C | ASTM A106 Giredhi C |
|---|---|---|
| Kabhoni (C) | 0.27 (kuongorora chigadzirwa) | 0.35 |
| Manganese (Mn) | 1.40 (kuongorora chigadzirwa) | 0.29 – 1.06 |
| Phosphorus (P) | 0.045 (kuongorora chigadzirwa) | 0.035 |
| Sarufa (S) | 0.045 (kuongorora chigadzirwa) | 0.035 |
| Silikoni (Si) | Hazvidikanwi | ≥ 0.10 |
Zvinonyanya kukosha kuti huwandu hwekabhoni muA500 Grade C (0.27%) hwakaderera pane hweA106 Grade C (0.35%), izvo zvinoita kuti A500 Grade C ikwanise kusvetwa zviri nani uye zvinoderedza njodzi yekutsemuka panguva yekusvetwa.
5. Kuenzanisa Zvimiro zveMichina
Zvinangwa zvesimba zvinosiyana: A500 Grade C ine simba rekukura, zvichiita kuti ive yakakodzera kudzivirira kushanduka kusingaperi muzvikamu zvechimiro, nepo A106 Grade C ine simba rekukura, zvichiratidza kugona kwayo kutsungirira kumanikidzwa kwemukati nekudzivirira kuputika.
| Pfuma | ASTM A500 Giredhi C | ASTM A106 Giredhi C |
|---|---|---|
| Simba Rishoma reGoho | 345 MPa (50,000 psi) | 275 MPa (40,000 psi) |
| Simba Rishoma Rekusimba | 425 MPa (62,000 psi) | 485 MPa (70,000 psi) |
| Kureba Kushoma | 21% | Kazhinji yakakwira, yakakodzera kukotama, kuputira, nezvimwewo. |
A106 Giredhi C inoita kuti ikwanise kupfava zviri nani, zvichiita kuti ive yakakodzera kukotama, kuputira, uye mamwe mabasa ekugadzira mapaipi. A500 Giredhi C, kune rumwe rutivi, inowana simba rayo rakakwirira kuburikidza nekushanda nesimba panguva yekuumbwa kwechando.
6. Nzvimbo Dzinoshanda uye Makodhi Einjiniya
Mitemo miviri iyi inoshandiswa munzvimbo dzakasiyana uye inotevera makodhi akasiyana ekugadzira:
| Chikamu | ASTM A500 Giredhi C | ASTM A106 Giredhi C |
|---|---|---|
| Tembiricha yekudziya | Zvivakwa zvisingachinji zviri munzvimbo ine zvakatipoteredza uye tembiricha yakaderera; hapana zvinodiwa pakushanda kwetembiricha yepamusoro | Yakagadzirirwa zvakanyanya kushandiswa pakupisa kwakanyanya, kusvika pa427°C zvichikwira |
| Maitiro akajairika | Mafuremu ekuvaka, mabhuroko emabhiriji, zvinotsigira michina, zvivakwa zveshongwe | Nzvimbo dzekuchenesa, magwenya emagetsi, bhaira rinopisa zvakanyanya/rinomanikidza zvakanyanya uye mapaipi ekugadzirisa |
| Makodhi ekugadzira | AISC (American Institute of Steel Construction) makodhi ekuvaka | ASME B31.1 (Mapaipi Emagetsi), B31.3 (Mapaipi Ekugadzirisa), uye mamwe makodhi emapaipi ekumanikidza |
7. Nhungamiro dzeSarudzo
Mukusarudza zvinhu zveinjiniya zvinoshanda, misimboti inotevera inogona kushandiswa:
- Chimiro chekutanga: Kana mufananidzo uchida chubhu ine sikweya, rectangular, kana chimiro chakasarudzika, sarudza ASTM A500 Giredhi C - A106 haibudisi maumbirwo aya zvachose.
- Pamachubhu akatenderera, funga nezvekushandiswa: Kana iri koramu yechimiro, brace yakatambanudzwa, kana nhengo yetruss iri pasi pemitoro yemhepo, mitoro yakafa, kana mamwe masimba ekunze → sarudza ASTM A500 Giredhi C. Kana iri michina yekubatanidza pombi, inotakura utsi kana hydrocarbon fluids pasi pekumanikidzwa kwakanyanya kwemukati nekupisa → sarudza ASTM A106 Giredhi C.
- Tembiricha: Kune zvikamu zvechimiro chetembiricha yemhepo, sarudza A500 Giredhi C; kune masisitimu emapaipi acharamba achishanda patembiricha yakakwira (≥350°C), sarudza A106 Giredhi C.
Muchidimbu: pakutakura mutoro wechimiro, shandisa A500 Grade C; pakutakura mvura inopisa zvakanyanya, shandisa A106 Grade C. Izvi zviviri hazvichinjiki muinjiniya.
