Imigqa yegesi engaphansi komhlaba - isithombe sensimbi ye-x65 ssaw efakiwe

Incazelo emfushane:

Kwethulwa ipayipi lethu lensimbi le-SSAW elisha, umkhiqizo osezingeni eliphezulu owenzelwe izinhlelo ezahlukahlukene, ikakhulukazi amapayipi egesi yemvelo engaphansi komhlaba. Le mpopayi yelayini ye-X65 SSAW isetshenziswa kabanzi emaphethelweni e-welding fluid ezokuhamba, izakhiwo zensimbi, izisekelo zenqwaba, njll. Ngokusebenza kwayo okuphezulu nokuqina, lo mkhiqizo uthathwa njengeminye imisebenzi ehlukahlukene kanye namaphrojekthi wengqalasizinda.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Kuvunguza i-arc efakwe i-arcged Ingxenye ebalulekile yobunjiniyela bamanzi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukunisela kwezolimo, kanye nokwakhiwa kwezolimo. Ukuguquguquka kwayo kanye nokuthembela kuye kwakwenza kwaba ngomunye wemikhiqizo engamashumi amabili ebekiwe athuthukiswe ezweni lethu, ekhombisa ukubaluleka kwayo kanye nomthelela emikhakheni ehlukahlukene.

Ipayipi lensimbi le-Ssawyenzelwe ngokwezifiso ukuthutha koketshezi futhi kufanelekile ngokufanele ukutholakala kwamanzi nezinhlelo zokudonsa amanzi. Ukwakhiwa kwalo okuqinile kwenza kube kuhle ekuqinisekiseni ukudluliswa koketshezi okusebenzayo nokuthembekile. Ngaphezu kwalokho, futhi ilungele ukuthuthwa kwegesi okufana negesi yamalahle, umusi, kanye nogesi we-petroleum petroleum. Amandla ayo aphezulu aphezulu kanye nokuphikiswa kokugqwala kuqinisekisa ukulethwa kwegesi okuphephile nokusebenza kahle futhi ahlangabezane nezidingo eziqinile zezinhlelo zokulethwa kwegesi.

Enye yezinhlelo zokusebenza eziphambili zamapayipi ethu ensimbi afakwe emanzini afakiweumugqa wegesi engaphansi komhlaba. Ngekhwalithi yayo ephezulu nasekusebenzeni kwayo okuphezulu, kungukuqala kokuqala kokwakha amanethiwekhi okuhamba athembekile wemvelo wemvelo.

I-X65 SSAW Line PipeKwakhiwa kusuka ezintweni ezisezingeni eliphakeme ziqinisekisa amandla aphezulu nokukhulisa. Lokhu kwenza kube kuhle ngezicelo ezidinga ingcindezi ephezulu kanye nokumelana nezici zezemvelo. Ukufaneleka kwalo kokufakwa ngaphansi komhlaba kuqokomisa ukwakhiwa kwayo okuqinile kanye nekhono lokumelana nezimo eziyinselele, okwenza kube yisixazululo sokukhetha amaphrojekthi angaphansi komhlaba wegesi.

Njengomkhiqizo othembekile futhi ofakazelwe, amapayipi ethu e-arcy afakwe e-arcy amukelwe amukelwa kabanzi kuzo zonke izimboni kanye namaphrojekthi wengqalasizinda ngenxa yokusebenza kwawo okuphezulu, ukuqina kanye nokwethenjwa. Ukwakhiwa kwalo osezingeni eliphakeme kwenza kube ngukukhetha okokuqala kwezinhlelo zokuhamba ngoketshezi kanye negesi, ikakhulukazi emgqeni wegesi ongaphansi komhlaba lapho ukuphepha nokusebenza kahle kubalulekile.

Ngokufingqwa, Kuvunguza i-ARCH WELDED STEM PIPE yensimbi yomkhiqizo omuhle kakhulu owenzelwe ukufeza izidingo ezahlukahlukene zezinhlelo zokulethwa kwegesi. Ngenxa yokuguquguquka okuhlukahlukene kanye nokwethenjwa, sekuyingxenye enkulu emikhakheni ehlukahlukene kanye namaphrojekthi wengqalasizinda, ikakhulukazi umugqa wegesi ongaphansi komhlaba. Ikhwalithi yayo ehlukile nokusebenza kwayo kwenza kube yimpahla ebalulekile ekuqinisekiseni inethiwekhi yokuhambisa igesi esebenzayo nephephile. Thembela ukuthembeka nokusebenza kwamapayipi ethu e-weldied ane-arc afakwe kuyo wonke ama-arc yazo zonke izidingo zakho zokuhamba zegesi kanye negesi.

Okwedlule: Kuvunguza i-arc efakwe i-arc ye-polyethylene yamapayipi e-polyethylene
