Kuyambitsa S235 J0 Spiral Steel Tube: Tsogolo la Kukhulupirika Kwamapangidwe


Tsatanetsatane wa Zamalonda

Zogulitsa Tags

M'dziko lomwe likusintha nthawi zonse la zomangamanga ndi uinjiniya, kufunikira kwa zida zapamwamba kwambiri zomwe zimatsimikizira chitetezo, kulimba, komanso kuchita bwino ndizofunikira.S235 J0 Spiral Chitoliro chachitsulondi chinthu chosinthika chomwe chapangidwa kuti chikwaniritse miyezo yokhazikika yamapangidwe amakono. Njira yatsopanoyi siili chitoliro chabe; ndi umboni wa njira zamakono zamakono ndi kupanga zomwe zimayika patsogolo mphamvu ndi kudalirika.

Mapaipi achitsulo a S235 J0 amapangidwa motsatira miyezo yaku Europe yomwe imatanthawuza ukadaulo woperekera magawo oziziritsa omwe amapangidwa mozizira. Izi zikutanthauza kuti chitoliro chilichonse chimapangidwa pogwiritsa ntchito njira yozizirira bwino, kuonetsetsa kuti kukhulupirika kwapangidwe kumasungidwa popanda kufunikira kwa chithandizo chotsatira cha kutentha. Mapeto ake ali ndi zida zabwino zamakina, zomwe zimapangitsa kuti zikhale zabwino kwambiri pakugwiritsa ntchito ntchito zambiri zomanga, zomangamanga ndi mafakitale.

a. Njira ya deoxidation imayikidwa motere:

FF: Chitsulo chophedwa kwathunthu chokhala ndi zinthu zomangira za nayitrogeni mu kuchuluka kokwanira kumanga nayitrogeni yomwe ilipo (mwachitsanzo min. 0,020 % okwana Al kapena 0,015 % sungunuka Al).

b. Mtengo wapamwamba wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al zomwe zili 0,020 % ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati zinthu zina zokwanira za N-binding zilipo. Zinthu zomangiriza za N zidzalembedwa mu Inspection Document.

Kuyesedwa kwa Hydrostatic

Utali uliwonse wa chitoliro uyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe idzapangitse mukhoma wa chitoliro kupsinjika kosachepera 60% ya mphamvu zokolola zosachepera zomwe zafotokozedwa kutentha. Kupanikizika kumatsimikiziridwa ndi equation yotsatirayi:
P=2St/D

Kusiyanasiyana Kololedwa Pakulemera ndi Makulidwe

S235 J0 Spiral Chitoliro chachitsulo

 

Chimodzi mwazinthu zodziwika bwino za S235 J0 Spiral Steel Tube ndi kusinthasintha kwake. Zopezeka mozungulira, makwerero ndi mawonekedwe amakona anayi, mankhwalawa amatha kusinthidwa kuti agwirizane ndi zosowa za polojekiti iliyonse. Kaya mukumanga chimango cholimba cha nyumba yamalonda, kupanga mapangidwe odabwitsa a zomangira, kapena kupanga zida zofunikira monga milatho ndi tunnel, S235 J0 Spiral Steel Tube imapereka kusinthasintha ndi mphamvu zomwe zimafunikira kuti mukwaniritse masomphenya anu.

Matchulidwe a S235 akuwonetsa kuti chubucho chimapangidwa kuchokera kuzitsulo zomangika zomwe zimakhala ndi weldability kwambiri komanso machinability. Izi ndizofunikira makamaka pamapulojekiti omwe amafunikira kupangidwa mwaluso komanso kukonza. J0 suffix imasonyeza kuti zinthuzo zimatha kupirira kutentha kochepa, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'madera ovuta kumene kusinthasintha kwa kutentha kungapangitse chiopsezo ku kukhulupirika kwapangidwe. Kuphatikizana kwazinthu izi kumatsimikizira kuti chubu chachitsulo cha S235 J0 sichingokhala chodalirika, komanso chimatha kupirira nyengo zosiyanasiyana.

Kuphatikiza apo, mawonekedwe ozizira a S235 J0 ozungulira chitsulo chitoliro amamupatsa kutha kwapamwamba komanso kulondola kwazithunzi. Izi zikutanthauza kuti chitolirocho chikhoza kuphatikizidwa mosavuta mu machitidwe omwe alipo popanda kusintha kwakukulu. Malo osalala amathandizanso kukongola kwa chinthu chomaliza, ndikupangitsa kukhala chisankho chapamwamba kwa omanga ndi okonza mapulani omwe amayamikira magwiridwe antchito ndi mawonekedwe.

mipope yachitsulo yozungulira

Kuphatikiza pa zabwino zake zaukadaulo, S235 J0 chitoliro chachitsulo chozungulira ndi chisankho chokonda zachilengedwe. Njira yopangira zinthu imachepetsa kuwononga komanso kugwiritsa ntchito mphamvu, mogwirizana ndi kukula kwazomwe zikuchitika pantchito yomanga. Posankha mankhwalawa, simukungoyika ndalama zokhazokha, komanso mukuthandizira kuti mukhale ndi tsogolo labwino.

Zonse, S235 J0 Spiral Steel Tube ndi yankho lapamwamba lomwe limagwirizanitsa bwino mphamvu, kusinthasintha komanso kukhazikika. Kaya mukuyamba ntchito yomanga yatsopano kapena mukufuna kupititsa patsogolo nyumba yomwe ilipo, izi zidapangidwa kuti zikwaniritse zomwe mukuyembekezera. Kutsatira miyezo yaku Europe komanso mawonekedwe abwino kwambiri, S235 J0 Spiral Steel Tube ndiye chisankho choyenera kwa mainjiniya, omanga ndi omanga omwe amafunikira zida zabwino kwambiri zamapangidwe. Landirani tsogolo la zomangamanga ndi S235 J0 Spiral Steel Tube - kuphatikiza kwatsopano komanso kudalirika.
