Iphayiphi Lensimbi Elingenamthungo laseChina Lekhwalithi Enhle YaseChina
Inkampani yethu ihlose ukusebenza ngokwethembeka, ukusebenzela wonke amakhasimende ethu, nokusebenza ngobuchwepheshe obusha kanye nomshini omusha njalo we-Steel Seamless Pipe.Khuluma nathi.Inkampani yethu ilandela imithetho nokwenza kwamazwe ngamazwe.Sithembisa ukuba nesibopho kubangani, amakhasimende kanye nabo bonke ozakwethu.Sithanda ukusungula ubudlelwano besikhathi eside nobungane nawo wonke amakhasimende avela emhlabeni wonke ngesisekelo sezinzuzo ezifanayo.Samukela ngokufudumele wonke amakhasimende amadala namasha ukuthi avakashele inkampani yethu ukuze axoxisane ngebhizinisi.
Uhlolojikelele
Isicelo
Isetshenziselwa Ikakhulukazi izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.

Isidingo Sokuhlola
Ukuhlolwa kwe-tensile, ukuhlolwa kokugoba, ukuhlolwa kwe-hydrostatic, ukuhlolwa kukagesi okungonakalisi kwama-welds.
