Ukubaluleka kwe-ASTM A139 Ekwakhiweni Kwepayipi Legesi Yemvelo Ngaphansi Komhlaba

Incazelo emfushane:

Lapho kwakhiwa amapayipi egesi yemvelo angaphansi komhlaba, kubalulekile ukusebenzisa izinto ezifanele ukuqinisekisa ukuphepha, ukuqina, nokusebenza kahle.Into eyodwa evame ukusetshenziswa lapho kwakhiwa le migqa yegesi i-ASTM A139, okuwumgomo ojwayelekile wepayipi lensimbi lensimbi elivunguzayo.Kule bhulogi, sizohlola ukubaluleka kwe-ASTM A139 ekwakhiweni kwepayipi legesi yemvelo ngaphansi komhlaba nokuthi idlala kanjani indima ebalulekile ekuqinisekiseni ubuqotho nokuthembeka kwalezi zingxenye ezibalulekile zengqalasizinda.

Kuvunguza ashiselwe ipayipi lensimbi lensimbi elakhiwe ukuzeI-ASTM A139yakhelwe ngokukhethekile ukusetshenziswa komhlaba okufana nokudluliswa kwegesi yemvelo kanye nezinhlelo zokusabalalisa.Lawa mapayipi akhiqizwa kusetshenziswa inqubo yokushisela okukhethekile eyakha amajoyinti aqinile futhi aqinile, abaluleke kakhulu ekubhekaneni nezingcindezi ezingaphansi komhlaba kanye nezimo zemvelo la mapayipi azobhekana nazo.

Inqubo yokushisela okuvunguzayo esetshenziswa ku-ASTM A139 inika ipayipi indawo yangaphakathi engaguquki futhi ebushelelezi, okubalulekile ekuqinisekiseni ukugeleza kahle kwegesi yemvelo ngepayipi.Lawa mapayipi ayatholakala futhi ngezinhlobonhlobo zamadayamitha kanye nobukhulu bodonga, okuvumela ukuguquguquka ekuklanyweni nasekukhiweni ukuze kuhlangabezane nezidingo ezithile zokudlulisa igesi yemvelo noma uhlelo lokusabalalisa.

Ngaphezu kokuthembeka nokuqina, ipayipi le-ASTM A139 linikeza ukumelana nokugqwala, okubalulekile ekuqinisekiseni ubuqotho besikhathi eside bamapayipi egesi yemvelo angaphansi komhlaba.Insimbi ye-carbon steel esetshenziswa kula mapayipi yakhelwe ngokukhethekile ukumelana nokugqwala, iqinisekisa ukuthi amapayipi ahlala eqinile ngokwesakhiwo futhi engavuzi iminyaka ezayo.

Ukuphepha kubaluleke kakhulu ekwakhiweni kwamapayipi egesi yemvelo angaphansi komhlaba.Amapayipi e-ASTM A139 akhiqizwa futhi avivinywa kumazinga aqinile nezicaciso zemboni, ukuqinisekisa ukuthi angakwazi ukumelana nezinselelo eziyingqayizivele zezicelo ezingaphansi komhlaba.Lokhu kunikeza izinsiza zegesi yemvelo, abalawuli kanye nokuthula kwengqondo komphakathi ukwazi ukuthi ingqalasizinda eletha igesi yemvelo ithembekile futhi iphephile.

Sengiphetha, i-ASTM A139Kuvunguza ashiselwe carbon steel pipeidlala indima ebalulekile ekwakhiweni kwamapayipi egesi yemvelo angaphansi komhlaba.Ukuqina kwazo, ukumelana nokugqwala kanye nokuhambisana nezindinganiso zemboni kuzenza zilungele amaphrojekthi engqalasizinda abalulekile njengalena.Uma kuziwa ekuqinisekiseni ukuphepha, ukwethembeka, kanye nokusebenza kahle kwezinhlelo zokudlulisa nokusabalalisa igesi yemvelo, kusetshenziswa ipayipi le-ASTM A139 kuyisinqumo esingenakuzitshwa.Ngokukhetha izinto ezifanele zalezi zicelo ezingaphansi komhlaba, singaqinisekisa ukuthi ingqalasizinda yethu yegesi yemvelo ihlala iphephile futhi ithembekile ezizukulwaneni ezizayo.

Okwedlule: Ukubaluleka Kwezinqwaba Zamashubhu Ensimbi Ekwakhiweni Kwelayini Yamanzi Angaphansi

Olandelayo: Ukubaluleka kwamapayipi ashiselwe kabili kanye namapayipi ane-Polyurethane Lined ku-Pipe Welding
