Izinga le-JIS G 3456 linamabanga amathathu ngokuya ngamandla aqinile wepayipi.
I-STPT370,STPT410 kanye ne-STPT480
Amele amashubhu anamandla amancane okudonsa angu-370, 410, kanye no-480 N/mm² (MPa) ngokulandelanayo.
Ama-Raw material
Amapayipi azokwenziwa ngensimbi ebulewe.
Insimbi ebulewe iwuhlobo olukhethekile lwensimbi olubonakala ngokwengezwa kwezakhi ezithile, njenge-aluminium ne-silicon, ngesikhathi senqubo yokuncibilika ukuze imunce futhi ibophe umoya-mpilo kanye nokunye ukungcola okuyingozi ensimbi.
Le nqubo isusa ngokuphumelelayo amagesi nokungcola, ngaleyo ndlela ithuthukise ukuhlanzeka nokufana kwensimbi.
I-JIS G 3456 Izinqubo Zokukhiqiza
Ikhiqizwe kusetshenziswa inhlanganisela efanele yezinqubo zokukhiqiza ishubhu nezindlela zokuqeda.

NgobaIsinyathelo 480ipayipi lezinga, ipayipi lensimbi elingenamthungo kuphela elizosetshenziswa.
Uma i-resistance welding isetshenziswa, ama-welds ezindaweni zangaphakathi nangaphandle zepayipi zizosuswa ukuze kutholakale i-weld ebushelelezi.
Ipayipi End
Ipayipi kufanele ibeekupheleni flat.
Uma ipayipi idingeka ukuthi icutshungulwe ekugcineni okugobile, ngokuqina kodonga ≤ ipayipi lensimbi engu-22mm, i-engeli ye-bevel ingu-30-35 °, ububanzi be-bevel bonqenqema lwepayipi lensimbi: i-max 2.4mm.
Ubukhulu bodonga obukhulu kuno-22mm wepayipi lensimbi elishelelayo ekugcineni, elivame ukucutshungulwa njenge-bevel eyinhlanganisela, ukuqaliswa kwamazinga kungabhekisela ezidingweni ezifanele ze-ASME B36.19.
Ukwelashwa Okushisayo
Khetha inqubo efanele yokwelapha ukushisa ngokuya ngebanga kanye nenqubo yokukhiqiza.

Ukubekezelela Ukwakheka Kwamakhemikhali
Amapayipi ensimbi angenamthungo azobhekana nokubekezelelwa kuThebula 3 le-JIS G 0321.
Amapayipi ensimbi anensimbi eqinile azobhekana nokubekezelelana kuThebula 2 le-JIS G 0321.
I-Tensile Test ye-JIS G 3456
Izindlela Zokuhlola: Izindlela zokuhlola zizohambisana namazinga aku-JIS Z.2241.
Ipayipi kufanele lihlangabezane nezidingo ezinikezwe kuThebula lesi-4 zamandla aqinile, amandla okukhiqiza, nokwelula.
Ucezu lokuhlola olusetshenziswayo luyoba lukaNombolo 11, No. 12 (No. 12A, No. 12B, noma No. 12C), No. 14A, No. 4 noma No. 5 olucaciswe ku-JIS Z 2241.
Ububanzi besiqephu sokuhlola No. 4 sizoba ngu-14 mm (ubude begeji 50 mm).
Izingcezu zokuhlola No. 11 kanye noNo. 12 zizothathwa ngokuhambisana ne-axis yepayipi,
Izingcezu zokuhlola No. 14A kanye no-4, ngokuhambisana noma nge-perpendicular ku-axis yepayipi,
kanye nesiqephu sokuhlola esingunombolo 5, ku-perpendicular eksisi yepayipi.
Ucezu lokuhlola No. 12 noma No. 5 oluthathwe ku-electric resistance welded steel pipe ngeke luqukathe i-weld.
Ukuze kuhlolwe ukushuba kwamapayipi angaphansi kuka-8 mm ubukhulu okwenziwa kusetshenziswa ucezu Lokuhlola No. 12 noma ucezu Lokuhlola No. 5, imfuneko yokwelulwa enikezwe kuThebula lesi-5 izosebenza.
Isilingo Sokucaba
Emazingeni okushisa asekamelweni (5°C - 35°C), caba isifanekiso phakathi kwamapulatifomu amabili size sifikeibanga (H) phakathi kwawo lifinyelela inani elishiwo bese uhlola ukuqhekeka.
H=(1+e)t/(e+t/D)
н: ibanga phakathi kwamapuleti (mm)
t: ukujiya kodonga lwepayipi (mm)
D: ngaphandle kobubanzi bepayipi (mm)
е: kuchazwe njalo ebangeni ngalinye lepayipi:
0.08 ye-STPT370,
0.07 ye-STPT410 kanye ne-STPT480
I-Bendability Test
I-Bendability isebenza kumapayipi anobubanzi obungaphandle obungu-60.5 mm noma ngaphansi.
Indlela yokuhlola Emazingeni okushisa asekamelweni (5°C kuya ku-35°C), goba ucezu lokuhlola uzungeze i-mandrel kuze kube yilapho indawo engaphakathi iphindwe izikhathi ezingu-6 ububanzi bangaphandle bepayipi futhi uhlole ukuqhekeka.Kulesi sivivinyo, i-weld kufanele ibekwe cishe ku-90 ° kusukela engxenyeni engaphandle yokugoba.
Ukuhlolwa kwe-Bendability nakho kungenziwa ngokuhambisana nemfuneko yokuthi i-radius yangaphakathi iphindwe kane ububanzi bangaphandle bepayipi kanye ne-engeli yokugoba i-180 °.
Ukuhlolwa kweHydraulic noma Ukuhlolwa Okungabhubhisi (NDT)
Ukuhlolwa kwe-hydraulic noma ukuhlolwa okungabhubhisi kuyokwenziwa epayipini ngalinye.
Ukuhlolwa kweHydraulic
Bamba ipayipi okungenani ekucindezelweni okuncane kokuhlolwa kwe-hydraulic okucaciswe okungenani imizuzwana emi-5 futhi uqaphele ukuthi ipayipi liyakwazi ukumelana nokucindezela ngaphandle kokuvuza.
Isikhathi se-Hydraulic sicacisiwe ngokusho kweSheduli yepayipi yensimbi.

Ukuhlolwa Okungonakali
Uma kusetshenziswa ukuhlolwa kwe-ultrasonic, amasiginali asuka kumasampula ereferensi aqukethe izilinganiso zereferensi zohlobo lwe-UD, njengoba kucaciswe ku-JIS G 0582, azosetshenziswa njengamaleveli e-alamu;noma iyiphi isignali evela epayipini elingana noma enkulu kuneleveli ye-alamu izonqatshwa.Ukwengeza, ubuncane bokujula kwezindawo eziyisikwele zokuhlola amapayipi, ngaphandle kokuphothula okubandayo, kuzoba ngu-0.3 mm.
Uma kusetshenziswa ukuhlolwa kwamanje kwe-eddy, amasiginali asuka kuzinga lereferensi lohlobo lwe-EY njengoba acaciswe ku-JIS G 0583 azosetshenziswa njengeleveli ye-alamu;noma iyiphi isignali evela epayipini elingana noma enkulu kuneleveli ye-alamu kuyoba isizathu sokwaliwa.

I-Dimensional Tolerances
Ukubukeka
Indawo yangaphakathi nengaphandle yepayipi izoba bushelelezi futhi ingabi namaphutha angalungile ukuyisebenzisa.
Ipayipi kufanele iqonde, iziphetho zibe ngama-engeli angakwesokudla ku-axis yepayipi.
Amapayipi angase alungiswe ngokugaya, ngomshini noma ezinye izindlela, kodwa ukujiya kodonga olulungisiwe kuzohlala ngaphakathi kokubekezelelana okucacisiwe futhi indawo elungisiwe izoba bushelelezi kuphrofayela.
Ukuqina kodonga lwepayipi elilungisiwe kufanele kugcinwe ngaphakathi kokubekezelelana okucacisiwe futhi ubuso bepayipi elilungisiwe buyoba bushelelezi kuphrofayela.
I-JIS G 3456 Ukumaka
