M'magawo omwe ali ndi zofunikira zolimba pachitetezo—monga kupanga magetsi, mankhwala a petrochemical, ndi kupanga zitsulo—ubwino wa mapaipi achitsulo umakhudza mwachindunji moyo wonse wa polojekitiyi komanso chitetezo cha ntchito. Monga wogulitsa mapaipi achitsulo waluso, timazindikira kuti satifiketi ya ISO 9001 ndi yoposa satifiketi chabe; imayimira njira yonse yotsimikizira khalidwe yomwe imadutsa gawo lililonse la kupanga, kuyambira zipangizo zopangira mpaka chinthu chomalizidwa. Nkhaniyi ikufotokoza machitidwe oyang'anira khalidwe ndi miyezo ya mapaipi achitsulo kuti ifotokoze chifukwa chake mapaipi a boiler ovomerezeka (A335mndandanda),machubu ozungulira (EN10210ndimapaipi olumikizidwa (EN10219) ndi chisankho chodalirika chomwe chikugwirizana ndi zosowa zanu.
I. ISO 9001: "Chitsimikizo Chadongosolo" cha Ubwino wa Chitoliro cha Chitsulo
Phindu lalikulu la dongosolo loyendetsera khalidwe la ISO 9001 lili pakukhazikitsa njira ya PDCA (Plan-Do-Check-Act) yopitirizira kukonza zinthu. Kwa opanga mapaipi achitsulo, izi zikutanthauza kuti gawo lililonse—kuyambira kugula zinthu zopangira ndi kuwongolera njira zopangira mpaka kuwunika zinthu zomalizidwa—limayendetsedwa ndi miyezo yokhazikika komanso yothandizidwa ndi zolemba zotsimikizika.
Makampani opanga mapaipi achitsulo omwe ali ndi ziphaso pansi pa ISO 9001 ayenera kugwiritsa ntchito njira yowongolera khalidwe lonse. Zitsanzo zamakampani zikuwonetsa kuti atagwiritsa ntchito satifiketi iyi, opanga mapaipi olumikizidwa achepetsa kuchuluka kwa zolakwika zolumikizidwa kuchokera pa 2.3% mpaka 0.8% ndikuchepetsa ndalama zotayira zinthu zopangira ndi 18%; kudzera mu Statistical Process Control (SPC), mtengo wa Cpk wa njira zofunika kwambiri ukhoza kukhazikika pamwamba pa 1.67. Machitidwe otsatirika omwe amafunikira ndi satifiketi amathandizira kutsata kuchokera kumapeto mpaka kumapeto kuchokera ku zitsulo zopangira mpaka mapaipi omalizidwa, kuonetsetsa kuti mavuto aliwonse akhoza kutsatiridwa molondola ndikuthetsedwa mkati mwa maola 24.
Kuphatikiza apo, satifiketi ya ISO 9001 imagwira ntchito ngati "pasipoti" yopikisana m'misika yamkati ndi yapadziko lonse lapansi, ndikuchotsa bwino zopinga zamalonda apadziko lonse lapansi. Mabizinesi ambiri otsogola m'mafakitale—monga Hunan Shengli Xianggang Steel Pipe ndi Changzhou Tianzhan Steel Pipe—apeza satifiketi ya ISO 9001 "Integrated Management System" kuti apititse patsogolo mbiri yawo pamsika. Kusankha wogulitsa mapaipi achitsulo wovomerezeka kumatanthauza kusankha njira yotsimikizira khalidwe yomwe imadziwika ndi kutsata, kuwongolera njira, komanso kusintha kosalekeza.
Machubu a boiler ndi zinthu zofunika kwambiri mu ma boiler amagetsi, ma superheaters mumakampani opanga mafuta, mapaipi a nthunzi, ndi mapaipi amphamvu kwambiri a zida zamagetsi za nyukiliya. Mapaipi achitsulo a chromium-molybdenum alloy osasenda omwe amaphimbidwa ndiMuyezo wa ASTM A335amapangidwira makamaka kuti agwiritsidwe ntchito pa kutentha kwambiri komanso kuthamanga kwambiri.
Magiredi oyambira a A335 omwe timapanga ndi awa:
A335 P11(1.25Cr-0.5Mo): Yoyenera kutentha mpaka pafupifupi 538°C; imagwiritsidwa ntchito kwambiri mu ma boiler superheaters, mapaipi obwezeretsanso kutentha, ndi ma header ogawa nthunzi.
A335 P22(2.25Cr-1Mo): Imatha kugwira ntchito kutentha mpaka 580°C ndi kupsinjika ≥9.8 MPa; imapereka kukana kwabwino ku dzimbiri la hydrogen ndipo imagwiritsidwa ntchito ngati chida chokhazikika cha ma header a nthunzi yamphamvu m'mafakitale amagetsi.
A335 P91(9Cr-1Mo-V-Nb): Yoyenera kutentha mpaka pafupifupi 593°C; imapereka mphamvu yokwera nthawi 2-3 kuposa P22, zomwe zimathandiza kuchepetsa makulidwe a khoma ndi 30%–50% pansi pa kapangidwe kofanana, motero kuchepetsa kwambiri kulemera kwa makina opaira mapaipi.
Kupanga machubu a boiler abwino kwambiri amenewa kumafuna kuwongolera kwambiri njira. Machubu a boiler a A335 P91 okhala ndi mphamvu yayikulu amagwiritsa ntchito njira ya magawo atatu—kusungunuka kwa Electric Arc Furnace (EAF), kuyeretsa Ladle Furnace (LF), ndi Vacuum Degassing (VD)—kuti zitsimikizire kuti chitsulo chili choyera. Njira zochiritsira kutentha zimakhudza mwachindunji katundu wa zinthu, ndipo kuwongolera mwamphamvu kutentha koyambirira ndi kutentha kotentha pambuyo pa weld ndikofunikira. Mfundo zonse zofunika kwambiri izi zimayang'aniridwa motsatira dongosolo loyang'anira khalidwe la ISO 9001.
TheMuyezo wa EN10210imalongosola momwe zinthu zimaperekedwera pazigawo zotentha zopangidwa ndi zitsulo zosapanga aloyi ndi zaufa. Zogulitsa zathu zamachubu a sikweya zimapangidwa motsatira muyezo uwu wa ku Europe, zomwe zimaphatikizapo zinthu mongaS235JRH, S275JOHndiS355J2H.
Muyezo wa EN10210 umatchula zofunikira zaukadaulo pa kukula, mawonekedwe, kulemera, kulekerera, katundu wa zinthu, mawonekedwe a makina, ndi mtundu wa pamwamba. Pansi pa EN10210, kulekerera makulidwe a khoma kumayendetsedwa pa ± 1% (osachepera ± 0.5 mm), ndi kulekerera kwa m'mimba mwake wakunja pa ± 1%. Zogulitsazi zimagwiritsidwa ntchito kwambiri m'magawo monga uinjiniya wa zomangamanga zachitsulo, kupanga makina, kumanga milatho, ndi zomangamanga zamagalimoto ndi zombo.
Kukhala ndi satifiketi iwiri ya ISO 9001 ndi EN10210 kumatanthauza kuti machubu athu a sikweya samangokwaniritsa miyezo yokhwima ya ku Europe yolondola komanso amakhala ndi kuwongolera kwabwino komwe kungatsatidwe panthawi yonse yopanga.
TheMuyezo wa EN10219Zimakhudza zofunikira pa kapangidwe ka mankhwala, mawonekedwe a makina, ndi mayeso olekerera magawo achitsulo chofewa chopangidwa ndi thovu chozizira. Zogulitsa zathu za mapaipi ofewa zimaphatikizapo mitundu yonse ya zinthu, kuyambiraS235JRHmpaka S460MLH.
EN10219 imatchula zofunikira zomveka bwino zololera kukula kwa m'mimba mwake wakunja, makulidwe a khoma, kutalika, ndi kutalika kwa msoko wothira. Magiredi osiyanasiyana azinthu amafanana ndi mphamvu zosiyanasiyana za zokolola ndi milingo yolimba; mwachitsanzo, S235JRH imapereka mphamvu ya zokolola ya ≥235 MPa (ya makulidwe a khoma ≤16 mm), pomweS355J2Himapereka kulimba kwa mphamvu ya ≥27 J pa -20°C.
Makampani omwe ali ndi satifiketi ya ISO 9001 nthawi zambiri amawona kuwonjezeka kwa 12% mpaka 15% kwa chiwongola dzanja cha zinthu zawo zolumikizidwa paipi. Timatsatira kwambiri muyezo wa ISO 9001:2015, kusunga dongosolo lonse loyang'anira khalidwe lomwe limakhudza njira zolembedwa, kuwongolera njira, kasamalidwe ka zinthu, ndi kuyeza, kusanthula, ndi kukonza, ndikuwonetsetsa kuti chitoliro chilichonse cholumikizidwa cha EN10219 chikugwirizana ndi miyezo yapadziko lonse lapansi.
V. N’chifukwa Chiyani Tiyenera Kusankha Ife?
Chitsimikizo cha Dongosolo: Timagwiritsa ntchito mosamala kwambiri njira yoyendetsera khalidwe la ISO 9001, kuonetsetsa kuti zinthu zonse zikuyenda bwino kuyambira kugula zinthu zopangira mpaka kutumiza zinthu zomalizidwa. Miyezo Yokwanira: Zogulitsa zathu zimaphatikizapo miyezo yayikulu yapadziko lonse lapansi, kuphatikizapo ASTM A335 (machubu a boiler), EN10210 (magawo otsekedwa bwino otsekedwa bwino), ndi EN10219 (magawo otsekedwa bwino opangidwa ndi thovu lozizira).
Kutsata Kwathunthu: Zolemba zonse zopangira ndi zikalata zabwino zimasungidwa pa gulu lililonse, kuonetsetsa kuti zikutsatira kwathunthu panthawi yonse yogwirira ntchito.
Kutsimikizira kwa Gulu Lachitatu: Zikalata zovomerezeka ndi EN 10204 3.1 kapena 3.2 zilipo, zomwe zimatsimikizira kuti zikutsatira 100% pankhani ya kapangidwe ka mankhwala ndi mawonekedwe a makina.
Posankha machubu a boiler, magawo ozungulira obowola, kapena mapaipi olumikizidwa, satifiketi ya ISO 9001 si mapeto—ndi poyambira pa kudzipereka kwathu pa khalidwe. Kusankha ife kumatanthauza kupeza chithandizo cha dongosolo lotsimikizira khalidwe lovomerezeka padziko lonse lapansi.
Lumikizanani nafe kuti mupeze tsatanetsatane wa zinthu zomwe zagulitsidwa komanso satifiketi yaubwino—lolani miyezo ilankhule ndipo ubwino wake udzitsimikizire wokha.
