Uma ufuna ukwazi ulwazi olwengeziwe, njengekhotheshini, imikhiqizo, izixazululo, njll., pqashaxhumana nathi ku-inthanethi.
I-Tianjin Sanon Steel Pipe Co., Ltd. ingumthengisi wamasheya. Ifektri yethu yamasheya iseDolobheni laseCangzhou, eSifundazweni saseHebei. Imithombo yethu eyinhloko yezimpahlaamapayipi ebhoyila, futhi izinto ezimele ziyiI-ASTM A335 P5/P11/P91/P92,I-ASME SA-106/SA-106MGR.B,I-GB/T 3087-200810#/20#. Izinto ezimele amapayipi epayipi yileziI-API 5L,I-API 5CT, izinto ezimele amapayipi okuqhekeka kwephethiloliI-GB/T 9948ziyi-15MoG/12CrMoVG. I-GB/T 6479-2013 imele izinto ezingu-10#/20#, amashubhu okushintshanisa ukushisa i-SA179/SA210/SA192, njll., amashubhu omshini i-GB/T 8162 amele izinto ezingu-10#/20#/Q345/42CrMo, i-EN10210 imele izinto ezingu-S355JOH/S355J2H, amashubhu esilinda segesi i-GB1 8248, amele izinto ezingu-34CrMo4/30CrMo.
1. Isingeniso: Ibanga elifanayo, i-DNA ehlukile
Ngokwezincazelo zensimbi yesakhiwo,S355J2Hkuyimfuneko evamile yeizingxenye ezingenaluthoKodwa-ke, kubonakala ngaphansi kwezindinganiso ezimbili ezihlukile zokukhiqiza:I-EN 10210futhiI-EN 10219Nakuba igama elithi "S355J2H" livame ukukhohlisa abathengi ukuthi bacabange ukuthi bayafana, indlela yokukhiqiza—futhi ngenxa yalokho ukusebenza—ihluka kakhulu.
Lesi sihloko siqhathanisa i-EN 10210 S355J2H (Eqediwe Ngokushisayo) ne-EN 10219 S355J2H (Eyenziwe Ngobandayo) ukuze kucaciswe umehluko wazo womshini, izici zokubonakala, kanye nokufaneleka kokusetshenziswa.
2. Umehluko Oyinhloko: Inqubo Yokukhiqiza
EN 10210 - Okuqediwe Okushisayo (S355J2H)
Izingxenye ezingaphansi kwe-EN 10210 zakhiwa emazingeni okushisa aphezulu (ngokuvamile ngaphezu kwezinga lokushisa lokuphinda kusetshenziswe). Le nqubo "Yokuqedwa Okushisayo" ikhulula ukucindezeleka kwangaphakathi okudalwe ngesikhathi sokubumba. Ngaphakathi kwe-EN 10210, i-S355J2H ivame ukukhiqizwa ngendlela yokunciphisa ukucindezeleka (ukushisa ngaphansi kuka-850°C) noma indlela e-Fully Normalized (ukushisa ngaphezu kuka-850°C ukuze kusethwe kabusha isakhiwo sezinhlamvu). Amashubhu ajwayelekile anikeza ukuguquguquka okuphezulu kanye nokufana.
EN 10219 - Okwenziwe Ukubanda (S355J2H)
Izingxenye ezingaphansi kwe-EN 10219 zakhiwe ngokushisa kwegumbi kusuka ku-coil yensimbi noma ipuleti. Insimbi iyagoba bese ishintshwa (ngokuvamile i-ERW noma i-SAW). Lokhu kusebenza okubandayo kuqinisa insimbi, ikakhulukazi ekugobeni nasemakhoneni, kuvaleleke ekucindezelekeni okuphezulu okusele.
3. Ukuqhathanisa Imininingwane Yobuchwepheshe (S355J2H)
Nakuba imikhawulo yokwakheka kwamakhemikhali ifana, ukusebenza komshini kanye nokubekezelelana okuvunyelwe kuyashintsha ngenxa yendlela yokwakha.
| Impahla | I-EN 10210-1(Kuqediwe Okushisayo) | I-EN 10219-1(Okwenziwe Ukubanda) |
| Ukushisa Okwakhayo | Ngaphezulu Kokuvuselelwa Kabusha (Okushisayo) | Isimo sezulu / Izinga lokushisa legumbi (Ukubanda) |
| Amandla Okukhiqiza (ReH) (T ≤ 16mm) | ≥ 355 MPa | ≥ 355 MPa |
| Amandla Okuqina (Rm) (3mm ≤ T ≤ 40mm) | 470 – 630 MPa | 470 – 630 MPa *(Qaphela: uhlu lwe-specs lwe-EN10219 490-630 lwe-T<3mm)* |
| Ukwelulwa | Ubuncane obungu-22% (Ukuqina okuphezulu ngenxa yokwelashwa kokushisa) | Ubuncane obungu-20% (Kuphansi ngenxa yokuqina komsebenzi) |
| Ukuqina Komthelela (KV) | 27J @ -20°C | 27J @ -20°C |
| Ukucindezeleka Okusele | Okuphansi (Okuncishisiwe ukushisa) | Phezulu (Kuvaliwe ekwakheni) |
| Irediyasi Yekona (SHS/RHS) | < 2T (Kuqine kakhulu, kubukhali kakhulu) | 1.6T ~ 3.6T (Irediyasi enkulu) |
4. Umehluko Obonakalayo Nobukhulu
Umphumela "wokuncinza" (Ukucindezeleka Okusele): Izingxenye ezakhiwe ngokubandayo (EN 10219) zinomkhuba wemvelo "wokubuyela emuva" noma "wokuncinza" lapho zinqunywa ngenxa yamandla asele agciniwe. Izingxenye eziqediwe ngokushisa (EN 10210) zihlala zizinzile ngokwesilinganiso ngemva kokunqunywa.
Amakhona: Ngezingxenye Eziyindilinga Eziyisikwele Nezingunxande (SHS/RHS), i-EN 10219 ivumela irediyasi yekona efika ku-3.6 ubukhulu bodonga (T), okuholela emakhoneni ayindilinga kakhulu. Izingxenye ze-EN 10210 eziqediwe ngokushisa (ikakhulukazi ezijwayelekile) zithola irediyasi ebukhali kakhulu (ngokuvamile <2T), enikeza indawo ebanzi esebenza kahle.
Ubukhulu Bodonga: I-EN 10210 ngokuvamile inikeza ukubekezelelana kobukhulu obuqinile uma kuqhathaniswa ne-EN 10219.
5. Yikuphi Okufanele Ukhethe?
KhethaI-EN 10210-1 S355J2Huma:
Izicelo ezibalulekile zesakhiwo: Amabhuloho, ama-crane booms, izindawo zokuzamazama komhlaba, noma amapulatifomu asogwini lolwandle.
Ukumelana Nokukhathala Okuphezulu: Ukushisela noma ukulayisha okunamandla kudinga ukuthi izinto zibe nokucindezeleka okuphansi okusele ukuze kuvinjelwe ukuqala kokuqhekeka.
Izidingo Zobuhle/Ukunemba: Udinga amakhona aqinile kanye nokuqondile okubikezelwayo kwensimbi evezwe ngokwakhiwa.
Ukwakheka kokushisa: Uma uhlela ukwenza ukugoba okukhulu noma ukwakheka kokushisa, izinto ezijwayelekile ziziphatha ngendlela ebikezelwayo.
Khetha i-EN 10219-1 S355J2H uma:
Ukusebenza kahle kwezindleko: Ukwakheka kobandayo ngokuvamile kushibhile futhi kulula ngokwesilinganiso esijwayelekile.
Ukwenziwa okuvamile: Izakhiwo eziphansi, izitezi ze-mezzanine, izinsika zocingo, noma imishini yezolimo lapho ukucindezeleka okuncane okusalayo kungeyona ingozi yokuwa.
Ukutholakala: Yishubhu "ejwayelekile" evame kakhulu etholakala kubathengisi bezimpahla abavamile emhlabeni jikelele.
6. Isexwayiso Esibalulekile ku-"S355J2H"
Qaphela: Akuwona wonke amashubhu e-EN 10210 S355J2H adalwe ngokulinganayo.
Abakhiqizi bangakhiqiza amashubhu e-EN 10210 ngokusebenzisa "Ukucindezeleka Okuncishisiwe" noma "Okujwayelekile Ngokugcwele."
I-S355J2H ejwayelekile (Edambiswa Ukucindezeleka): Ihlangabezana nezindinganiso kodwa igcina ukucindezeleka okuthile. Ishibhile.
I-S355NH (Ejwayelekile): Ibanga elithile ngaphansi kwe-EN 10210 elidinga ukulungiswa okugcwele (izinga lokushisa eliphezulu). Lona umkhiqizo osezingeni eliphezulu wokushisela.
Uma udinga i-ductility ephezulu kakhulu kanye nokucindezeleka okusele okungenayo i-residue ukuze ushisele, thuthukisa i-spec yakho ibe yi-EN 10210 S355NH kune-J2H ejwayelekile.
