    Apha kwiCangzhou Spiral Steel Pipes Group Co., Ltd., siyazingca kakhulu ngokubonisa impumelelo yethu yamva nje kushishino lweepayipi zentsimbi -Umbhobho we-SSAWLe mveliso intsha idibanisa itekhnoloji yanamhlanje kunye nobuchule obungenakuthelekiswa nanto ukubonelela ngezisombululo ezingenamthungo kwiintlobo ngeentlobo zezicelo.

    Umbhobho we-SSAW nguumbhobho odibeneyo ojikelezayozenziwe ngeekhoyili zentsimbi ezikumgangatho ophezulu. Sisebenzisa iteknoloji yokukhupha ephucukileyo ukuqinisekisa ubushushu obuhambelanayo kuyo yonke inkqubo yemveliso, size emva koko senze i-arc welding ezenzekelayo enamacala amabini. Le teknoloji inobuchule iqinisekisa ukubopha okuqinileyo nokuhlala ixesha elide, okubangela umbhobho oqinileyo nothembekileyo.

    Enye yezona nzuzo zibalulekileyo zeityhubhu edibeneyo ejikelezayongamandla ayo aphezulu, adlula lawo epayipi edityanisiweyo ethe tye. Oku kuyenza ifaneleke kwiiprojekthi ezifuna ukuqina okuphuculweyo kwesakhiwo. Ukongeza, ngenxa yenkqubo yayo yokuvelisa eyahlukileyo, ipayipi edityanisiweyo ejikelezayo inokuveliswa kusetyenziswa iibhilethi zentsimbi ezincinci, okuvumela ukuveliswa kweepayipi ezinkulu ezinobubanzi obufanayo. Ukongeza, ngokusebenzisa iibhloko ezinobubanzi obufanayo, singenza ngokulula iityhubhu ezinobubanzi obahlukeneyo, sandise ngakumbi ukuguquguquka kwayo.

    Umbhobho we-SSAW
