JIS G 3444 Njira Zopangira
Machubu adzapangidwa ndi kuphatikiza njira yopangira chubu ndi njira yomaliza yomwe ikuwonetsedwa.
Machubu amatha kutenthedwa bwino ngati angafune.
Ngati Wogula akufuna, chitolirocho chikhoza kupangidwa kuchokera ku pepala lachitsulo chophimbidwa kapena chitsulo chophimbidwa.Pankhaniyi, mtundu wa zokutira ndi mtundu wa ❖ kuyanika zikugwirizana ndi zofunikira za JIS G 3444, Zowonjezera A.
Mitundu ya zokutira zomwe zingagwiritsidwe ntchito ndi zokutira za zinki zotentha, zokutira za electrolytic zinki, zokutira zotentha za aluminiyamu, zokutira zotentha za zinc-5% aluminium alloy, kutentha-kuviika 55% aluminium-zinc alloy coating, kapena kutentha- kuviika zinc-aluminium-magnesium alloy zokutira.

Kulimbitsa Mphamvu ndi Kutulutsa Malo kapena Kupanikizika Kwaumboni
Kulimba kwamphamvu ndi zokolola kapena kutsindika kwa umboni komanso mphamvu yamphamvu pa weld idzakwaniritsa zomwe zafotokozedwa mu Table 3.
Kulimba kwamphamvu kwa weld kumagwiritsidwa ntchito pamachubu odziyimira pawokha.
Mphamvu ya weld ndi yofanana ndi yofunikira pa thupi la chitoliro.Mbali yowotcherera nthawi zambiri imakhala cholumikizira chofooka mu kapangidwe kake, kotero kukhala ndi mphamvu yofananirako kumatsimikizira kudalirika kwa kapangidwe kawo.
Table 3 ilinso ndi mtunda wofunikira pakukana kwa Flattening ndi zofunikira za bend angle ndi bend radius kumapeto kwa bendability.
Elongation
Kutalikitsa kolingana ndi njira yopangira machubu kukuwonetsedwa mu Gulu 4.
Komabe, pamene kuyesa kwamphamvu kumachitidwa pa Test Piece No. 12 kapena Test Piece No.5 yotengedwa mu chubu pansi pa 8 mm mu makulidwe a khoma, kutalika kwake kudzakhala molingana ndi Table 5.
Flattening Resistance
Ikani chidutswa choyesera pa kutentha wamba (5 ° C mpaka 35 ° C) pakati pa mbale ziwiri zathyathyathya ndi compress kuti flatten mpaka mtunda pakati pa mbale H kukhala wofanana kapena wocheperapo kuposa mtengo wotchulidwa mu Table 3, kenako fufuzani ming'alu pa gawo la mayeso.
Ikani welds wa kukana welded zitsulo chitoliro ndi matako welded zitsulo chitoliro kuti mzere pakati pa chitoliro ndi weld ndi perpendicular kwa malangizo a psinjika.
Bend Test
Pindani chidutswa choyesera mozungulira silinda pa kutentha wamba (5 °C mpaka 35 °C) ndi ngodya yopindika osati yocheperako pang'ono yopendekera yomwe yatchulidwa mu Table 3, ndi utali wamkati wosaposa utali wamkati wamkati wotchulidwa mu Table. 3, ndipo yang'anani chidutswa choyesera cha ming'alu.
Poyesa chubu chachitsulo chotchinga chamagetsi ndi chubu chachitsulo chowotcherera matako, ikani choyezeracho kuti chowotchereracho chikhale 90 °C kuchokera kumtunda kwa bend.
Mayesero Ena
Mayeso a Hydrostatic, mayeso osawononga ma welds, kapena mayeso ena amavomerezedwa pasadakhale pazofunikira.

JIS G 3444 Ntchito
Amagwiritsidwa ntchito popanga zomangamanga ndi zomangamanga monga nsanja zachitsulo, scaffoldings, milu yopondaponda, milu ya maziko, ndi milu yopondereza pansi.
Miyezo Yogwirizana
Chithunzi cha JIS G3452: Imatchula mapaipi achitsulo cha kaboni pazifukwa wamba (zosiyana ndi zomangika komanso zimayang'ana kwambiri pamayendedwe amadzi kapena mpweya).
Chithunzi cha JIS G3454: Limatchula mfundo mipope mpweya zitsulo kwa kuthamanga mapaipi.
ASTM A500: Imakwirira machubu opangidwa ndi chitsulo chozizira komanso osasunthika ndipo ndi ofanana ndi JIS G 3444 pazofunikira zake.
EN 10219: Imakwirira zigawo za dzenje zozizira zomwe zimapangidwira, kuphatikiza mbiri yozungulira, masikweya, ndi amakona anayi.
Ubwino Wathu
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 alloys apamwamba kwambiri ndi zitsulo zosapanga dzimbiri za austenitic, zopangidwa kuti zikwaniritse zofunikira zama projekiti osiyanasiyana a mapaipi.
