Muzvikamu zvine zvinodiwa zvakasimba zvekuchengetedza—zvakadai sekugadzira magetsi, petrochemicals, uye kuvaka simbi—hunhu hwemapaipi esimbi hunokanganisa zvakananga hupenyu hweprojekiti yese uye kuchengetedzeka kwekushanda kwayo. Semutengesi wemapaipi esimbi ane hunyanzvi, tinoziva kuti chitupa cheISO 9001 chinopfuura kungova chitupa; chinomiririra maitiro akazara ekusimbisa hunhu anotora nhanho yega yega yekugadzira, kubva pazvinhu zvakagadzirwa kusvika kuchinhu chapera. Chinyorwa chino chinoongorora masisitimu ekutarisira hunhu uye mwero wemapaipi esimbi kutsanangura kuti nei mapaipi eboiler akasimbiswa (A335nhevedzano),machubhu akaenzana (EN10210), uyemapaipi akasungirirwa (EN10219) ndiyo sarudzo yakavimbika inoenderana nezvaunoda.
I. ISO 9001: "Gwaro reSystemic" reHunhu hweSimbi yePipe
Kukosha kukuru kwehurongwa hwekutarisira mhando hweISO 9001 kuri mukugadzira nzira yePDCA (Plan-Do-Check-Act) yekuvandudza nguva dzose. Kune vagadziri vemapombi esimbi, izvi zvinoreva kuti danho rega rega—kubva pakutenga zvinhu zvisina kugadzirwa uye kudzora maitiro ekugadzira kusvika pakuongororwa kwechigadzirwa chapera—rinotongwa nematanho akatarwa uye rinotsigirwa nemagwaro anosimbiswa.
Makambani emapaipi esimbi ane zvitupa pasi peISO 9001 anofanira kushandisa nzira yekudzora mhando yakazara. Mienzaniso yeindasitiri inoratidza kuti mushure mekushandisa chitupa ichi, vagadziri vemapaipi akasungirirwa vakaderedza mwero wezvikanganiso zvewelding kubva pa2.3% kusvika ku0.8% uye vakaderedza mitengo yemarara ezvinhu zvisina kugadzirwa ne18%; kuburikidza neStatistical Process Control (SPC), kukosha kweCpk kwemaitiro akakosha kunogona kugadzikana pamusoro pe1.67. Masisitimu ekutevera anodiwa nechitupa anogonesa kuteverwa kubva kumakona esimbi emhando yepamusoro kusvika kumapaipi apera, zvichiita kuti chero matambudziko akwanise kuteverwa nemazvo uye kugadziriswa mukati memaawa makumi maviri nemana.
Uyezve, chitupa cheISO 9001 chinoshanda se "pasipoti" yekukwikwidzana mumisika yemuno neyepasi rose, zvichibvisa zvinobudirira zvipingamupinyi pakutengeserana kwenyika dzese. Makambani mazhinji anotungamira muindasitiri—akadai seHunan Shengli Xianggang Steel Pipe neChangzhou Tianzhan Steel Pipe—akawana chitupa cheISO 9001 "Integrated Management System" kuti arambe achisimbisa mukurumbira wavo mumusika. Kusarudza mutengesi wemapaipi esimbi ane chitupa zvinoreva kusarudza sisitimu yekusimbisa mhando inozivikanwa nekutevedza, kudzora maitiro, uye kuvandudza nguva dzose.
Machubhu ebhoyira ndiwo zvinhu zvikuru mumaboyira emagetsi, masuperheaters muindasitiri yepetrochemical, mapiping emhepo, uye masisitimu emapaipi ane simba repamusoro emidziyo yemagetsi enyukireya. Mapaipi esimbi asina musono akafukidzwa ne chromium-molybdenum alloy.ASTM A335 chiyerozvakagadzirirwa zvakananga mamiriro ekushanda anodziya zvakanyanya uye ane kumanikidzwa kwakanyanya.
Magiredhi ekutanga eA335 atinogadzira anosanganisira:
A335 P11(1.25Cr-0.5Mo): Yakakodzera tembiricha inosvika 538°C; inoshandiswa zvakanyanya mumaboiler superheaters, mapiping ereheater, uye ma steam distribution headers.
A335 P22(2.25Cr-1Mo): Inokwanisa kushanda patembiricha inosvika 580°C uye kumanikidzwa ≥9.8 MPa; inopa simba rekudzivirira hydrogen corrosion uye inoshanda sechishandiso chemidziyo yemhepo ine simba rakawanda mumafekitori emagetsi.
A335 P91(9Cr-1Mo-V-Nb): Yakakodzera tembiricha inosvika 593°C; inopa simba rekukwira nekudzika ka2-3 kupfuura P22, zvichibvumira kudzikiswa kweukobvu hwemadziro ne30%–50% mumamiriro akafanana ekugadzira, nokudaro zvichideredza zvakanyanya huremu hwemasisitimu epombi.
Kugadzira machubhu aya emhando yepamusoro kunoda kudzora kwakasimba maitiro. Machubhu ebhoyira ane simba repamusoro eA335 P91 anoshandisa maitiro ane matanho matatu—kunyungudutsa kweElectric Arc Furnace (EAF), kunatswa kweLadle Furnace (LF), uye Kubvisa Gassing (VD)—kuona kuti simbi yakachena. Maitiro ekurapa kupisa anokanganisa zvakananga hunhu hwezvinhu, uye kudzora kwakasimba pakupisa kwepamberi uye kupisa kwepashure peweld kwakakosha. Nzvimbo dzese idzi dzekutonga dzakakosha dzinotarisirwa pasi peISO 9001 quality management system.
IyoEN10210 chiyeroinotsanangura mamiriro ekugadzirwa kwezvivakwa zvine maburi akagadzirwa nesimbi dzisina alloy nedzakatsetseka. Zvigadzirwa zvedu zvemachubhu emativi mana zvinogadzirwa zvinoenderana nechiyero ichi cheEurope, zvichisanganisira mamakisi ezvinhu zvakaita seS235JRH, S275JOHuyeS355J2H.
Muyero weEN10210 unotsanangura zvinodiwa zvehunyanzvi zvehukuru, chimiro, huremu, kushivirira, hunhu hwezvinhu, hunhu hwemakanika, uye mhando yekumusoro. Pasi peEN10210, kushivirira ukobvu hwemadziro kunodzorwa pa ±1% (zvishoma ±0.5 mm), uye kushivirira dhayamita yekunze pa ±1%. Zvigadzirwa izvi zvinoshandiswa zvakanyanya muzvikamu zvakaita seinjiniya yesimbi, kugadzira michina, kuvaka mabhiriji, uye zvivakwa zvemotokari nekuvaka ngarava.
Kuva nesitifiketi mbiri dzeISO 9001 neEN10210 zvinoreva kuti machubhu edu emativi mana haangogumiri pamatanho eEurope ekururama asi anewo hunhu hwekutonga hunogona kuteverwa mukati menguva yese yekugadzira.
IyoEN10219 chiyeroinovhara zvinodiwa zvemakemikari, hunhu hwemakanika, uye kuyedzwa kwekushivirira kwezvikamu zvesimbi zvakasungirirwa zvakaumbwa zvinotonhora. Zvigadzirwa zvedu zvemapaipi akasungirirwa zvinosanganisira mhando dzakasiyana dzemhando dzezvinhu, kubvaS235JRHkusvika kuS460MLH.
EN10219 inotsanangura zvinodiwa zvakajeka zvekutsungirira dhayamita yekunze, ukobvu hwemadziro, kureba, uye kukwirira kwemusono we weld. Magiredhi akasiyana ezvinhu anoenderana nekusimba kwakasiyana kwegoho uye mazinga ekusimba kwemhedzisiro; semuenzaniso, S235JRH inopa simba regoho re ≥235 MPa (yeukobvu hwemadziro ≤16 mm), ukuwoS355J2Hinopa kusimba kwe ≥27 J pa -20°C.
Makambani ane chitupa cheISO 9001 anowanzoona kuwedzera kwe12%–15% mukupasa kwezvigadzirwa zvavo zvemapaipi akasungirirwa. Isu tinotevedzera zvakanyanya mwero weISO 9001:2015, tichichengetedza sisitimu yakazara yekutarisira mhando inovhara maitiro akanyorwa, kudzora maitiro, manejimendi yezviwanikwa, uye kuyera, kuongorora, uye kuvandudza, tichiona kuti pombi yega yega yakasungirirwa yeEN10219 inosangana nezvinodiwa zvepasi rose.
V. Sei Uchifanira Kutisarudza?
Kuvimbisa Sisitimu: Tinoshandisa zvakasimba sisitimu yekutonga mhando yeISO 9001, tichiona kuti zvinhu zvakagadzirwa zvakanaka zvinodzorwa kubva pakutenga zvinhu kusvika pakutumirwa kwezvinhu zvakagadzirwa. Mitemo Yakazara: Zvigadzirwa zvedu zvinofukidza mitemo mikuru yepasi rose, kusanganisira ASTM A335 (machubhu eboiler), EN10210 (zvikamu zvemasekonzi zvinopisa zvakapedzwa), uye EN10219 (zvikamu zvemasekonzi zvinotonhora zvakasungirirwa).
Kutevedza Kwakazara: Zvinyorwa zvakakwana zvekugadzira uye madosi emhando yepamusoro zvinochengetwa pabhechi rega rega, zvichiita kuti zvive nyore kutevedzera mukati mekuita kwese.
Kusimbiswa kweVamwe Vaviri: Zvitupa zvekushandisa zvinoenderana neEN 10204 3.1 kana 3.2 zvinodiwa zviripo, zvichivimbisa kutevedzera 100% maererano nekuumbwa kwemakemikari uye hunhu hwemakanika.
Pakusarudza machubhu ebhoyira, zvikamu zvemakomba zvikweya, kana mapaipi akasungirirwa, chitupa cheISO 9001 hachisi mugumo—ndicho mavambo ekuzvipira kwedu kwemhando yepamusoro. Kusarudza isu zvinoreva kuwana rutsigiro rwehurongwa hwekusimbisa mhando hwakabvumidzwa pasi rose.
Tibatei kuti muwane ruzivo rwakadzama nezvezvigadzirwa uye zvitupa zvemhando yepamusoro—regai mitemo itaure uye mhando yacho iratidze kuti yakagadzirwa sei.
