I-ASTM A139 S235 S235 J0 Spiral Steel Amapayipi
Enye yezinzuzo eziphambili zeS235 J0 Spiral Steel PipeIngabe ukuguquguquka kwayo kububanzi kanye nemininingwane yodonga. Lokhu kuvumela ukuguquguquka okukhiqizwayo okukhudlwana, ikakhulukazi ekukhiqizweni kwamapayipi aphezulu, odongeni olubi kakhulu. Ngaphezu kwalokho, ubuchwepheshe busebenza ngempumelelo ikakhulukazi ekukhiqizeni amapayipi abingelwe ngodonga amancane namadayimitha aphakathi, aqede ezinye izindlela ezikhona.

Izimfanelo eziphakeme ze-S235 J0 Spiral Pipe zizenze zilungele izinhlelo ezahlukahlukene. Yiba yizimboni, ezentengiso noma zengqalasizinda, lo mkhiqizo wenzelwe ukufeza izidingo eziqinile zabasebenzisi bayo. Ukusebenza kwayo okuthembekile nokuqina kwenza kube yisixazululo esisebenza ngempumelelo kunoma yiliphi iphrojekthi edinga amashubhu we-arc engaphakathi e-Spiral.
Ngaphezu kwe-S235 J0 Spiral Pipe, umugqa wethu womkhiqizo ufaka futhiI-A252 Ibanga 3 Ipayipi lensimbi. Umkhiqizo wenziwa kusetshenziswa ubuchwepheshe bamuva bokukhiqiza obuqinisekisa amazinga aphezulu kakhulu kanye nokwethenjwa. Ngamandla ayo aphezulu aphezulu kanye nokumelana okuhle kakhulu kokugqwala, i-A252 Ibanga 3 Ipayipi lensimbi lilungele izicelo ezifunwayo.
Siyaziqhenya ngokunikela ngomugqa ogcwele wepayipi le-arcy elifakwe emanzini angenamikhawulo elihlangana futhi lidlula amazinga ezimboni. Ukuzinikezela kwethu kwikhwalithi kanye ne-Innovation sesenze saba umphakeli othembekile embonini yensimbi yensimbi. Ngokuzibophezela okuhle, siyaqhubeka nokucindezela imikhawulo yokukhiqiza amapayipi wensimbi.
Uma kukhulunywa ngepayipi le-arcy elifakwe endaweni efakwe emanzini, imikhiqizo yethu ibeka indinganiso yokusebenza, ukuqina kanye nokwethembeka. I-S235 J0 Spiral Steel Pipe ne-A252 Ibanga 3 I-Steel Pipe liyizibonelo ezimbili nje zokuzibophezela kwethu ekunikezeni amakhasimende ethu ngezixazululo ezinhle kakhulu. Sigxile kwikhwalithi kanye nokwenziwa okusha futhi sizibophezele ekuhlangabezaneni nezidingo zamakhasimende ethu futhi sidlula okulindelwe.
Ngamafuphi, ipayipi lethu le-S235 J0 Spiral Spiral kanye ne-A252 Grade 3 Ipayipi lensimbi lingumphumela wobuchwepheshe obunqenqemeni nobungcweti obukhulu. Le mikhiqizo inikeza ukusebenza okungenakuqhathaniswa, okwenza ukuba kube ukukhetha okuhle kwezicelo ezahlukahlukene. Noma ngabe kwakhiwa, ingqalasizinda noma amaphrojekthi wezimboni, amapayipi ethu angenamikhawulo e-WELDC wezenzelwe ukuletha imiphumela ephakeme. Themba ukuthi ubuchwepheshe bethu kanye nesipiliyoni sethu kuzokunikeza amapayipi ensimbi aphezulu kakhulu emakethe.
