Amapayipi ngokuvamile azolethwa njengoba akhiqiziwe.Ipayipi elisetshenzwe ngokubanda lizodonswa ngemva kokuqedwa kokwakhiwa.
Uma inqubo yokukhiqiza i-welding ye-resistance isetshenziswa, ama-welds azosuswa ngaphakathi nangaphandle kwepayipi ukuze athole i-weld ebushelelezi eduze kwe-contour yepayipi.Ubuhlalu bokushisela endaweni engaphakathi angeke bususwe uma lokhu kungenxa yemishini noma imikhawulo yobubanzi bepayipi.
Uhlobo Lokuphela Kwepayipi le-JIS G 3452
Ukukhetha Kokuphela Kwepayipi
Uhlobo lwesiphetho sepayipi le-DN≤300A/12B: intambo noma isiphetho esiyisicaba.
Uhlobo lokuphela kwepayipi le-DN≤350A/14B: isiphetho esiyisicaba.
Uma umthengi edinga ukuphela kwe-beveled, i-engeli ye-bevel ingu-30-35 °, ububanzi be-bevel bonqenqema lwepayipi lensimbi: max 2.4mm.
Qaphela: Ku-JIS G 3452, kukhona uchungechunge oluthi A kanye nochungechunge lwe-B lwedayamitha encane ye-DN.Lapho u-A elingana ne-DN, iyunithi ingu-mm;B ilingana ne-NPS, iyunithi ingaphakathi.
Izidingo Zokuphela Kwepayipi Elinentambo
Amapayipi anemicu azokwenziwa ngokunikeza ipayipi iziphetho zemicu ye-taper njengoba kucacisiwe ku-JIS B 0203, futhi kufakwe umkhawulo owodwa ofakwe isikulufu (okuzobizwa kamuva ngokuthi isokhethi) okuhambisana ne-JIS B 2301 noma i-JIS B 2302.
Ukuphela kwepayipi ngaphandle kwesokhethi kufanele kuvikelwe ngendandatho yokuvikela intambo noma ezinye izindlela ezifanele.
Amapayipi anemicu angase ahlinzekwe ngaphandle kwamasokhethi uma lokho kucaciswe umthengi.Ukuhlolwa kwemicu ye-taper kuzohambisana ne-JIS B 0253.
Ukwakhiwa kwamakhemikhali kwe-JIS G 3452
Izidingo ezijwayelekile zokuhlaziywa kwamakhemikhali nezindlela zesampula zokuhlaziywa kokushisa kufanele zihambisane ne-JIS G 0404 isigatshana sesi-8. Indlela yokuhlaziya ukushisa kufanele ihambisane namazinga ku-JIS G 0320.
| Uphawu lwebanga | I-P (Phosphorus) | S (Sulfur) |
| I-SGP | ubuningi 0.040% | ubuningi 0.040% |
Amazinga aphezulu e-phosphorus nesibabule anciphisa ukusebenza kanye nezakhiwo ze-mechanical zensimbi futhi ajwayele kakhulu ukuba brittleness ngesikhathi sokushisela.Ngakho-ke, ikhwalithi kanye nokushisela kwamapayipi ensimbi ye-carbon kungaqinisekiswa ngokukhawulela okuqukethwe kwe-phosphorus nesibabule.
Ezinye izakhi ze-alloying nazo zingangezwa njengoba kudingeka.
Izakhiwo Zemishini ye-JIS G 3452
Izidingo ezijwayelekile zokuhlolwa kwemishini zizohambisana nemishwana engu-7 no-9 ye-JIS G 0404. Nokho, ezindleleni zesampula ezinikezwe ku-7.6 we-JIS G 0404, indlela yamasampula A kuphela esebenzayo.
Ukuhlolwa kwe-Tensile: Indlela yokuhlola izohambisana namazinga aku-JIS Z 2241.

Impahla Ephansi
Ezingeni lokushisa lasekamelweni (5℃~35℃), i-weld iqondana nendawo yokuminyanisa.Cindezela isifanekiso phakathi kwamapulatifomu amabili kuze kube yilapho ibanga H phakathi kwamapulatifomu lifinyelela izingxenye ezimbili kwezintathu zobubanzi obungaphandle bepayipi lensimbi eliphakathi nendawo, bese uhlola ukuqhekeka.
Ukugoba
Uma i-DN≤50A, yenza ukuhlolwa kokugoba.
Uma ugobela endaweni engaba ngu-90 ° izikhathi ezingu-6 ububanzi obungaphandle bepayipi, ucezu lokuhlola ngeke luveze noma yikuphi ukuqhekeka.Ngaphambi kokugoba, kala i-engeli yokugoba ukusuka endaweni eqondile.
Ukuhlolwa kweHydraulic noma Ukuhlolwa Okungabhubhisi (NDT)
Ipayipi ngalinye kufanele libe i-Hydraulic Test noma i-Nondestructive Test.
Ukuhlolwa kweHydraulic
Ipayipi kufanele imelane no-2.5MPa okungenani amasekhondi angu-5, ngaphandle kokuvuza.
Ukuhlolwa Okungonakali
Izici zokuhlola ezingonakali zingasetshenziselwa ukuhlolwa kwamanje kwe-ultrasonic noma i-eddy, futhi ipayipi lizohlangabezana nezici ezilandelayo zokuhlola ezingonakali.
Ukuze kuhlolwe i-ultrasonic, amasampula ayireferensi acaciswe ku-JIS G 0582 aqukethe amazinga ereferensi ekilasi le-UE azosetshenziswa njengeleveli ye-alamu;noma iyiphi isignali evela epayipini elingana noma enkulu kuneleveli ye-alamu izosetshenziswa njengezinga le-alamu.isignali izosetshenziswa njengezinga le-alamu;noma iyiphi isignali evela epayipini elingana noma enkulu kuneleveli ye-alamu izoba yisizathu sokwaliwa.
Ekuhloleni kwamanje kwe-eddy, amasiginali asuka kumasampuli ayireferensi aqukethe amazinga ereferensi wesigaba EZ njengoba acaciswe ku-JIS G 0583 azosetshenziswa njengamaleveli e-alamu;noma iyiphi isignali elingana noma enkulu kuneleveli ye-alamu evela epayipini kuyoba isizathu sokwaliwa.izosebenza njengezinga le-alamu;noma iyiphi isignali evela epayipini elingana noma enkulu kuneleveli ye-alamu izoba yisizathu sokwaliwa.Ngokubona komkhiqizi, ileveli ye-alamu enzima engaphansi kwesiginali yezinga lesithenjwa esishiwo ingasetshenziswa.
Ezinye izindlela zokuhlola ezingabhubhisi nazo zingasetshenziswa, isb ukuthola ukuvuza okuzenzakalelayo njengoba kucaciswe ku-JIS G 0586.
Ishadi Lesisindo Sombhobho kanye Nokubekezelelana Kwe-Dimensional
Steel Pipe Weight Calculation Formula
Kucatshangwa ukuthi i-1 cm3 yensimbi ingaba ngu-7.85g ngobuningi
W=0.02466t(Dt)
W: ubukhulu beyunithi yepayipi (kg/m);
t: ukujiya kodonga lwepayipi (mm);
D: ububanzi obungaphandle bepayipi (mm);
0.02466: isici sokuguqulwa sokuthola i-W;
Kufinyezwa kuzibalo ezintathu ezibalulekile ngokuhambisana ne-JIS Z 8401, umthetho A.
Ishadi Lesisindo Sombhobho kanye Nokubekezelelana Kwe-Dimensional
aUbubanzi bokuzisholo buzohambisana nanoma yiliphi igama elithi A noma B futhi ivezwe ngokunamathisela uhlamvu A noma B, noma yikuphi ukuqokwa okusetshenzisiwe, ngemva kwenombolo yobubanzi.
bEzingxenyeni ezikhandwe endaweni, ukubekezelelana kuleli thebula akusebenzi.
cEmapayipini anobubanzi obungu-350A noma ngaphezulu, ukulinganisa kobubanzi obungaphandle kungase kushintshwe ngobude obuyindilinga, lapho ukubekezelela okusetshenzisiwe kuzoba ngu-0.5 %.Ubude obuyindilinga obulinganisiwe (I) buzoguqulelwa kububanzi obungaphandle (D) kusetshenziswa ifomula elandelayo.
D=l/Π
D: ububanzi bangaphandle (mm);
l: ubude obuyindilinga (mm);
Π: 3.1416.
Ukubukeka Kwepayipi Lensimbi
Ukubukeka
Indawo yangaphakathi nengaphandle yepayipi izoba bushelelezi futhi ingabi namaphutha angalungile ukuyisebenzisa.
Ipayipi kufanele iqonde, iziphetho zibe ngama-engeli angakwesokudla ku-axis yepayipi.
Ukulungiswa Kwesici
Ipayipi elimnyama (ipayipi lensimbi elingenayo i-anti-corrosion treatment) lingalungiswa ngokugaya, ngomshini, noma ngezinye izindlela, futhi indawo elungisiwe izoba bushelelezi eduze kwekhontoyutha yepayipi.
Kodwa-ke, ukujiya kodonga olulungisiwe kugcinwa ngaphakathi kokubekezelelana okucacisiwe.
I-Surface Coating
Indawo eyodwa noma yomibili yepayipi ingagcotshwa isb, i-zinc-rich coating, epoxy coating, primer coating, 3PE, FBE, njll.
Ifakwe i-JIS G 3452
I-Hot Dip Galvanizing
Amapayipi ensimbi, uma efakwe uthayela, amapayipi anentambo namasokhethi kufanele ambozwe nge-zinc ngaphambi kokuqinisa izintambo.
Ukuhlanzwa kwensimbi okuphelele ngokuqhunyiswa kwesihlabathi, ukucotshwa, njll., okulandelwa ukuvundisa kwediphu elishisayo.
Ukuze kufakwe i-zinc, ingot ye-zinc ehlutshiwe ye-Class 1 ecaciswe ku-JIS H 2107 noma i-zinc enekhwalithi okungenani elingana nalokhu izosetshenziswa.
Ezinye izidingo ezijwayelekile zokumboza i-zinc zicaciswe ku-JIS H 8641.
Ukuhlolwa kwe-Galvanization
Indlela Yokuhlola Ngokwendlela yokuhlola eshiwo ku-Athikili 6 ye-JISH0401, isifanekiso sicwiliswa kusixazululo se-copper sulfate, iminithi elingu-1 izikhathi ezingu-5, futhi isifanekiso siyahlolwa ukuze kubonakale ukuthi sifika ekugcineni.
Ukumakwa kwe-JIS G 3452
Okuqukethwe kwe-logo kuqukethe okungenani izakhi ezilandelayo, ukuhleleka okungahle kuhlelwe ngokukhululekile.
