Katundu wamakina wa JIS G 3455
Zomwe zimafunikira pakuyesa kwamakina zizikhala molingana ndi ndime 7 ndi 9 ya JIS G 0404. Njira zoyeserera zamakina zimayenderana ndi Gulu A la JIS G 0404, Ndime 7.6.
Kulimba Kwamphamvu, Kutulutsa Pansi kapena Kupanikizika Kwaumboni, ndi Kutalikira
Njira yoyeserayi iyenera kukhala yogwirizana ndi miyezo ya JIS Z 2241.
Kwa mapaipi omwe amayezetsa kuyesedwa pogwiritsa ntchito chitsanzo No. 12 kapena No. 5, elongation idzakwaniritsa zofunikira za Table 5.
Flattening Resistance
Chiyesocho chikhoza kusiyidwa pakufuna kwa wopanga malinga ngati mipopeyo ikukwaniritsa kukana kwapadera kwa flattening.
Chitsanzocho chimayikidwa pakati pa nsanja ziwiri ndikuphwanyidwa mpaka mtunda wa H pakati pa nsanja ufike pamtengo wotchulidwa.Chitsanzocho chimafufuzidwa ngati chang'ambidwa.
H=(1+e)t/(e+t/D)
H: mtunda pakati pa mapulaneti (mm)
t: makulidwe a chitoliro (mm)
D: kunja kwake kwa chitoliro (mm)
е: kumasuliridwa kosalekeza kwa giredi iliyonse ya chitoliro: 0.08 kwa STS370, 0.07 kwa STS410 ndi STS480.
Bendability Test
Imagwiritsidwa ntchito pamapaipi okhala ndi m'mimba mwake ≤50 mm monga momwe wogula amanenera.
Chitsanzocho chizikhala chopanda ming'alu pamene chikupindika pa ngodya ya 90 ° ndi mkati mwake ka 6 kuwirikiza kwa kunja kwa chitoliro.Ngongole yopindika iyenera kuyezedwa kumayambiriro kwa bend.
Kuyesa kwa Hydrostatic kapena Nondestructive Test
Mayeso a hydrostatic kapena osawononga adzachitidwa pa chitoliro chilichonse.
Kuyesedwa kwa Hydrostatic
Gwirani chitoliro pamlingo wocheperako womwe watchulidwa kuti hydrostatic test pressure kwa masekondi osachepera 5 ndikuwonetsetsa kuti chitolirocho chingathe kupirira kukakamiza popanda kutayikira.
Pamene Wogula sakunena za kukakamizidwa kwa mayeso, ndipo pamene chitolirocho chikayesedwa ndi kuyesedwa kochepa kwa hydrostatic, chitolirocho chikhoza kupirira popanda kutayikira.

Pamene kupanikizika kocheperako kwa hydrostatic kuyesa kwa nambala yosankhidwa kupitilira kukakamiza koyesa P komwe kumapezeka ndi formula, kukakamiza P kudzagwiritsidwa ntchito ngati kuyesa kocheperako kwa hydrostatic m'malo mosankha kutsika kocheperako kwa hydrostatic test patebulo pamwambapa.
Mayeso Osawononga
Paipiyi iyenera kuyang'aniridwa ndi akupanga kuzindikira kapena kuzindikira kwa eddy.
Pazidziwitso za akupanga, ma sign a zitsanzo omwe ali ndi UD class reference standards otchulidwa mu JIS G 0582 adzatengedwa ngati alamu, ndipo palibe chizindikiro chofanana kapena chokulirapo kuposa alamu.
Pazidziwitso za eddy pakadali pano, chizindikiro cha sampuli chomwe chili ndi muyezo wa kalasi ya EY monga momwe zafotokozedwera mu JIS G 0583 chidzatengedwa ngati mulingo wa alamu, ndipo palibe chizindikiro chofanana kapena chokulirapo kuposa ma alarm.

Mawonekedwe
Mawonekedwe amkati ndi akunja a chitoliro adzakhala osalala komanso opanda zilema zosayenera kugwiritsa ntchito.
Malekezero a chitoliro chachitsulo adzakhala pa ngodya zolondola kwa olamulira chitoliro.
Kuyika chizindikiro
Chubu chilichonse chidzalembedwa ndi mfundo zotsatirazi.
a) Chizindikiro cha kalasi;
b) Chizindikiro cha njira yopangira;
Chitoliro chachitsulo chosakanizidwa chotentha chotentha: -SH
Chitoliro chozizira chozizira chopanda msoko: -SC
c) MakulidweChitsanzo 50AxSch80 kapena 60.5x5.5;

Pamene kukula kwa kunja kwa chubu chilichonse kuli kochepa ndipo kumakhala kovuta kuika chizindikiro chubu chirichonse, kapena pamene wogula akufuna kuti mtolo uliwonse wa machubu ulembedwe, mtolo uliwonse ukhoza kulembedwa ndi njira yoyenera.
Kugwiritsa ntchito kwa JIS G 3455 Pipe yachitsulo
Kupanga makina: Chifukwa cha mphamvu zake zazikulu komanso kukana kutentha, zimagwiritsidwa ntchito popanga zida zosiyanasiyana zamakina, monga zigawo za hydraulic systems ndi makina opangira mafuta othamanga kwambiri.
Machitidwe a mapaipi a mafakitale: Amagwiritsidwa ntchito kwambiri m'mafakitale omwe amafunikira kunyamula mwamphamvu kwambiri, monga mipope m'mafakitale opangira mankhwala, zoyenga, ndi malo ena opangira zinthu.Amatha kunyamula bwinobwino nthunzi, madzi, mafuta, ndi mankhwala ena.
Zomera zamagetsi: Amagwiritsidwa ntchito m'zigawo zofunika kwambiri monga ma boilers ndi ma superheaters omwe amatha kutentha kwambiri komanso kuthamanga kwambiri.
Kumanga ndi kumanga: Atha kugwiritsidwa ntchito pothandizira zomanga kapena ngati mapaipi oponderezedwa, makamaka komwe kumafunikira mphamvu zowonjezera komanso kulimba.

Zathu Zogwirizana
Chiyambireni kukhazikitsidwa mu 2014, Botop Steel yakhala ikugulitsa chitoliro chachitsulo cha carbon ku Northern China, chomwe chimadziwika ndi ntchito zabwino kwambiri, zinthu zamtengo wapatali, komanso zothetsera mavuto.
Kampaniyi imapereka mapaipi osiyanasiyana a zitsulo za carbon ndi zinthu zomwe zimagwirizana nazo, kuphatikizapo zopanda msoko, ERW, LSAW, ndi chitoliro chachitsulo cha SSAW, komanso mzere wathunthu wazitsulo ndi flanges.
Zopangira zake zapadera zimaphatikizanso ma aloyi apamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zofunikira zama projekiti osiyanasiyana amapaipi.
