China Brand New Q235C Q235B 16Mn Welded carbon steel umbhobho / ityhubhu
Isishwankathelo
Inkampani ixhasa ifilosofi ethi "Yiba ngoyena uphezulu malunga nesisombululo sombhobho", siya kuqhubeka nokusebenzela abathengi bangaphambili nabatsha abavela ekhaya naphesheya ngokushushu. Kwikhabhoni yentsimbi edityanisiweyo okanye umbhobho ongenamthungo olandela umgangatho we-ASTM A53, sineminyaka engaphezu kwama-30 amava okuthenga nokuthengisa, nto leyo enokuqinisekisa ukuba sinamandla okuqinisekisa umgangatho ophezulu wemibhobho nganye.
Malunga nombhobho ongenamthungo, kukho umbhobho womgunyathi ongenamthungo okhoyo, ongumatshini ongaphantsi kunombhobho ongenamthungo, kuba wenziwa kumbhobho we-ERW, emva kwenkqubo, umgca wokuwelda utshintshile waphantse wangabonakali. Lo mbhobho onobubele awukwazi ukuthwala uxinzelelo oluphezulu, kunye namandla okuqina, uxinzelelo lwangaphakathi lonke alukwazi ukuhlangabezana neemfuno malunga nombhobho ongenamthungo. I-Incase ukuxuba le mibhobho emibini yohlobo, nceda uqaphele ukuba umbhobho we-ERW wonke owenziwe kwimicu yentsimbi, ngoko unodonga olufana kakhulu; umbhobho ongenamthungo wenziwa kwibar engqukuva, ugqobhoze embindini webar engqukuva ukwenza imibhobho, ngoko ubukhulu bodonga abufani. Kwaye umgca we-weld wombhobho wobuxoki ongenamthungo usekho, ukuba ujonga umbhobho wangaphakathi ngononophelo, ungawufumana.
Isetyenziswa ikakhulu kumandla kunye noxinzelelo lwamalungu, kunye nenjongo eqhelekileyo yomphunga, amanzi, igesi kunye nemibhobho yomoya.

A Isimbuku sezi elementi zintlanu masingabi ngaphezu kwe-1.00%.
B Ngayo yonke i-0.01% yehla kwi-carbon content, umxholo we-manganese ophezulu uvumelekile ukuba unyuke ngo-0.06%, kodwa ubuninzi abukwazi ukudlula i-1.35%.
C Ukuncipha ngakunye kwe-0.01% kowona mxholo wekhabhoni uphezulu kuya kuvumela owona mxholo uphezulu wemanganese ukuba unyuke nge-0.06%, kodwa ubuninzi bungagqithi kwi-1.65%.
