I-Precision Seamless Steel Piping yokusetyenziswa koomatshini kunye nokukhanya kwesakhiwo.Oku kubangela ukuba kwiipropati ezifanayo kuwo wonke umbhobho xa kuthelekiswa nemibhobho eqhelekileyo.Ngelixa iityhubhu zoomatshini zinokuveliswa ngokwemigaqo eqhelekileyo xa iceliwe, iipropati “eziqhelekileyo” zidla ngokuveliswa kugxininiso lwamandla esivuno sobukhulu obuchanekileyo kunye nobukhulu beendonga.Kwezinye izicelo ezenziwe kakhulu, amandla okuvelisa angenakuchazwa kwaye ityhubhu yomatshini iveliswa "ilungele ukusetyenziswa".Iityhubhu zoomatshini zibandakanya uluhlu olubanzi lwezicelo zesakhiwo kunye nezingezizo ezobume.
EHaihui Steel, sisebenzisa ubuchule bethu besinyithi kunye nemveliso ukwenza iimveliso zemibhobho yomatshini ezingenamthungo eziphezulu zokusebenza ukuhlangabezana neemfuno zakho.
Oku kubandakanya i-carbon, i-alloys kunye namabakala entsimbi yesiko;i-annealed, iqhelekile kwaye inomsindo;uxinzelelo luthotyiwe kwaye alunaxinzelelo;epholile kwaye enomsindo.
Oomatshini kunye nemibhobho yentsimbi engenamthungo yemoto ye-automobile skeleton kunye nemibhobho ye-axle yangasemva, ukuveliswa kunye nokulungiswa kwezixhobo ezichanekileyo kunye nezixhobo.
Isicelo:
Umqolo we-Automobile kunye ne-axle tube yangasemva
Ukwenziwa kunye nokulungiswa kwezixhobo ezichanekileyo, izixhobo kunye nezixhobo
Imeko yonikezelo: GBK, BKS, BK, BKW, NBK
Ukuhlolwa noVavanyo:
Ukubunjwa kweMichiza, iiPropati zoomatshini, uvavanyo olubonakalayo kunye nobungakanani, i-NDT, uvavanyo lobungakanani beenkozo
Unyango loMphezulu:
I-oyile-dip, Varnish, Shot Blasting
