I-API 5L X65 PSL1/PSL2 LSAW Ipayipi Lensimbi Lekhabhoni iwuhlobo lwepayipi lensimbi yekhabhoni elenziwe ngensimbi yensimbi, elinomthungo oqondile endaweni yalo.Ububanzi balo bangaphandle bukhulu kakhulu, bufika ku-1500 millimeter.Inqubo yokukhiqiza enembile ikwenza kube ithuluzi elingcono kakhulu lokuthutha uwoyela negesi, elihlasele inani elikhulu lamakhasimende emhlabeni jikelele.
Njengomphakeli osezingeni eliphezulu we-LSAW, sinefektri enabasebenzi abanomthwalo wemfanelo. Enye yezinzuzo zenkampani yethu ukuthi sinesikhathi sokulethwa okusheshayo futhi sizoba nokuhlolwa okujulile kwayo yonke imikhiqizo ngaphambi kokuyiletha. Ngaphandle kwalokho, sihlala sikhumbula ukwenza kwethu okungcono kakhulu ukuhlangabezana nezidingo zamakhasimende ethu ezifana ne-ze, ukupeyinta okumnyama, Ukuhlobisa,I-3PE anti-corrosion, Amagalaniisivalo sepayipinjalo njalo.
Ukudala inzuzo ethe xaxa kubathengi ifilosofi yethu yebhizinisi;ukukhula kwamaklayenti kuwujaha lwethu lokusebenzaI-China Steel Line kanye nePipe Mill, Izinkinga eziningi phakathi kwabahlinzeki-mpahla namakhasimende zibangelwa ukuxhumana okubi.Ngokwesiko, abahlinzeki bangangabaza ukubuza amaphuzu abangawaqondi.Sidiliza leyo migoqo ukuze siqinisekise ukuthi uthola okufunayo ezingeni olilindele, ngesikhathi osifunayo.Isikhathi sokulethwa esisheshayo kanye nomkhiqizo owufunayo umbandela wethu.
I-API 5L X65 PSL1/PSL2LSAW Carbon Steel Pipengokuvamile isetshenziswa kumaphrojekthi weipayipi likawoyela negesi, emapayipini ahamba ngaphansi kolwandle, amapayipi adlula ezindaweni eziphakeme kanye nezindawo zasemadolobheni eziminyene.
I-API 5L X65 PSL1/PSL2 LSAW Ipayipi Lensimbi Lekhabhoni lakhiwa ngokwakha amapuleti ensimbi e-X65 abe yindilinga bese eshisela umthungo ngenqubo yokushisela i-arc ngokuzenzakalelayo.Ekukhiqizeni i-API 5L X65
I-PSL1&PSL2 LSAW Ipayipi Lensimbi Yekhabhoni, amapuleti ebanga le-X65 akhiwa umshini wokubumba abe yindilinga bese eshiselwa ngokusebenzisa ukushiselwa kwe-arc okungaphansi kwezinhlangothi ezimbili.
