Ukubaluleka kwe-ASTM A139 ekwakhiweni komhlaba wePipeline yemvelo engaphansi komhlaba

Ukubaluleka kwe-ASTM A139 endaweni engaphansi komhlaba ye-Pipelines I-Pipelines

Incazelo emfushane:

Lapho kwakha amapayipi emvelo wemvelo wemvelo, kubalulekile ukusebenzisa izinto ezifanele ukuqinisekisa ukuphepha, ukuqina nokusebenza kahle. Okunye okusetshenziswayo okuvame ukusetshenziswa lapho kwakhiwa le migqa yegesi yi-ASTM A139, okuyinto ecacisiwe ejwayelekile yepayipi le-Spiral Welded Carbon. Kule bhulogi, sizohlola ukubaluleka kwe-ASTM A139 ekwakhiweni kwepayipi yemvelo yemvelo engaphansi komhlaba nokuthi idlala kanjani indima ebalulekile ekuqinisekiseni ubuqotho kanye nokwethenjwa kwalezi zingxenye zezingqalasizinda ezibucayi.

Kuvunguza i-welded carbon irobholi yenziweI-ASTM A139Iklanyelwe ngokukhethekile izinhlelo zokusebenza ezingaphansi komhlaba ezifana nokudluliselwa kwegesi yemvelo nezinhlelo zokusabalalisa. Lawa mapayipi akhiqizwa kusetshenziswa inqubo ekhethekile ye-welding eyakha amalunga aqinile futhi aqinile, okubalulekile ukubekezelela izingcindezi ezingaphansi komhlaba kanye nezimo zemvelo ukuthi la mapayipi azobekwa ngaphansi.

Inqubo ye-Welding eluhlaza esetshenziswa e-ASTM A139 inikeza ipayipi elingaphakathi elingaphakathi elingaphakathi, elibalulekile ekuqinisekiseni ukuhamba okusebenzayo kwegesi yemvelo ngepayipi lemvelo ngepayipi. Lawa mapayipi ayatholakala ngama-diameter ahlukahlukene kanye nobukhulu odongeni, avumele ukuguquguquka ekwakhiweni nasekwakhiweni ukuze ahlangabezane nezidingo ezithile zokuhanjiswa kwegesi yemvelo noma uhlelo lokusabalalisa.

Ngaphezu kokuthembela nokuqina, i-ASTM A139 Pipe ihlinzeka ngokumelana nokuqina, okubalulekile ekuqinisekiseni ubuqotho besikhathi eside samapayipi egesi engaphansi komhlaba. Izinto zensimbi ze-carbon ezisetshenziswe kula mapayipi zakhiwa ngokukhethekile ukumelana nokugqwala, ukuqinisekisa ukuthi amapayipi ahlale enombono ohlelekile futhi evuvukala iminyaka ezayo.

Ukuphepha kubaluleke kakhulu ekwakhiweni kwamapayipi egesi emvelo engaphansi komhlaba. Amapayipi we-ASTM a139 akhiqizwa futhi ahlolwe kumazinga ezimboni aqinile kanye nokucaciswa, ukuqinisekisa ukuthi akwazi ukumelana nezinselelo ezihlukile zohlelo lokusebenza ngaphansi komhlaba. Lokhu kunikeza izinsiza zegesi zemvelo, abalawuli kanye nokuthula komphakathi kwengqondo bazi ukuthi ingqalasizinda enikezela igesi yemvelo ithembekile futhi iphephile.

Ekuphetheni, ASTM A139Kuvunguza i-welded carbon steel pipeUdlala indima ebalulekile ekwakhiweni kwamapayipi egesi emvelo engaphansi komhlaba. Ukuqina kwabo, ukumelana nokugqwala kanye nokuhambisana namazinga ezimboni kubenze balungele amaphrojekthi wengqalasizinda abucayi kanjena. Uma kukhulunywa ngokuqinisekisa ukuphepha, ukuthembeka, kanye nokusebenza kahle kwezinhlelo zegesi zemvelo kanye nezinhlelo zokuhambisa, ukusebenzisa i-ASTM A139 Pipeline kuyisinqumo esingenakunakwa. Ngokukhetha izinto ezifanele zalezi zinhlelo zokusebenza ezingaphansi komhlaba, singaqinisekisa ukuthi ingqalasizinda yethu yemvelo yemvelo ihlala iphephile futhi ithembekile ezizukulwaneni ezizayo ezizayo.
