Imboni eyenza i-China ASTM A53 Spiral Welded Carbon Steel Pipe SSAW Pipe
Uhlolojikelele
Ngobuchwepheshe bethu obuhamba phambili nomoya wethu wokusungula izinto ezintsha, ukubambisana, izinzuzo kanye nokukhula, sizokwakha ikusasa eliqhakazile kanye nepayipi lakho lensimbi elihlonishwayo eligcwalisiwe, Sigcina amashejuli okulethwa ngesikhathi, imiklamo emisha, ikhwalithi ephezulu nokuba sobala kwethu. abathengi. Imoto yethu kufanele ibe ukuhlinzeka ngempahla yekhwalithi ngesikhathi esibekiwe.
Siyakwamukela ukuvakashela inkampani yethu, ifekthri kanye nendawo yethu yokugcina impahla lapho kuboniswa khona amasheya ethu azohlangabezana nokulindela kwakho. Okwamanje, kulula ukuvakashela iwebhusayithi yethu, futhi abasebenzi bethu bokuthengisa bazozama konke okusemandleni abo ukukuletha isevisi engcono kakhulu. Qiniseka ukuthi uyasithinta uma udinga ulwazi olwengeziwe. Inhloso yethu ukusiza amakhasimende ukuthi abone izinhloso zawo. Senza imizamo emikhulu ukuze sifinyelele lesi simo esiphumelelayo.
Mayelana nepayipi le-carbon steel elishiselwe, kukhona i-poeple enomusa ebizwa ngokuthi ipayipi le-MS, okusho amapayipi enziwe ngensimbi ethambile/insimbi enekhabhoni ephansi(insimbi enekhabhoni enekhabhoni engaphansi kuka-0.25%). Leli payipi elinomusa livame kakhulu, ikakhulukazi lisetshenziselwa isakhiwo sokwakha, i-scaffold nokunye. Leli payipi elinomusa lithambile uma kuqhathaniswa, alikwazi ukubekezelela amandla amaningi nokucindezela, ngakho futhi lingasetshenziswa ekuthuthweni koketshezi olunomfutho ophansi. Ngoba lolu hlobo lwensimbi lunomshini ophansi, ngeke lusetshenziswe kumshiniukusetshenziswa isimo esinesidingo esikhulu, ngakho-ke lapho abantu bekhuluma ngepayipi le-MS, njalo kusho ipayipi elishiselwe.
Isicelo
Isetshenziselwa Ikakhulukazi izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.
