Isishwankathelo
Umnqophiso wethu uhlala uphuhlisa ube ngumboneleli ovelisa izinto ezintsha zedijithali kunye nezixhobo zonxibelelwano ngokunikezela ngexabiso loyilo olongezelelweyo, ukuveliswa komgangatho wehlabathi, kunye nokulungiswa kwezakhono ze-Seamless / ERW welded Stainless / Carbon / Alloy Galvanized Square / round Seamless Steel Pipe, Izinto zethu ezithengiweyo zithunyelwe kuMbindi Mpuma, eYurophu, eKorea, eVietnam, e-Iraq, eRashiya nakwamanye amazwe. Sijonge phambili ukwenza intsebenziswano entle nehlala ixesha elide kunye nawe kwikamva elibonakalayo! Sinezisombululo ezizezona zilungileyo kunye neentengiso zeengcali kunye neqela lobugcisa.Ngophuhliso lwenkampani yethu, siyakwazi ukubonelela abathengi ngezona mveliso zibalaseleyo, inkxaso yobugcisa elungileyo, inkonzo egqibeleleyo emva kokuthengisa.
Isicelo
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%.

A Ubuncinane bobude begeyiji yobude obuyi-2in. (50mm) iya kumiselwa ngale fomula ilandelayo:
e=625000(1940)A0.2/U0.9
e = ubuncinane bobude begeyiji 2in. (50mm), ipesenti isondezwe kweyona 0.5% ikufutshane;
A = Kubalwa ngokwe-diameter yangaphandle echaziweyo yetyhubhu yegama okanye ububanzi begama lesampulu ye-tensile kunye nobukhulu bayo obuchaziweyo bodonga, kwaye ijikelezwe kwindawo ekufutshane ye-cross-sectional ye-tensile yesampuli ye-0.01 in.2 (1 mm2), kwaye Ithelekiswa ne-0.75in.2 (500mm2), nokuba yeyiphi encinci.
U = ubuncinci bamandla okuqina, i-psi (MPa).
B Kwiindibaniselwano ezahlukeneyo zobukhulu obahlukeneyo besampulu zovavanyo lwe-tensile kunye namandla amiselweyo amiselweyo, ubuncinane bobude obufunekayo buboniswa kwiTheyibhile X4.1 okanye kwiTheyibhile X4.2, ngokokusebenza kwayo.
Imfuneko yoVavanyo
Uvavanyo lwe-tensile, uvavanyo lokugoba, uvavanyo lwe-hydrostatic, uvavanyo lombane olungonakalisiyo lwe-welds.
