Otu n'ime isi ihe na-ahụ maka iguzosi ike n'ezi ihe nke ntinye pipeline gas na-eji spiral submerged arc welded steel pipe bụ nhọrọ nke usoro ịgbado ọkụ kwesịrị ekwesị.Nke a gụnyere iji nlezianya tụlee ụzọ ịgbado ọkụ, ihe ndochi na nkwadebe tupu welding.Na mgbakwunye, nnabata na ụkpụrụ ụlọ ọrụ na ụkpụrụ dị oke mkpa iji hụ na ntụkwasị obi na nchekwa nkeeriri gassusoro.
Nkwadebe nke ọma tupu ịgbado ọkụ dị oke mkpa iji hụ na ịgbado ọkụ nke spiral submerged arc welded steel pipes na nrụnye ahịrị gas.Nke a na-agụnye ihicha nke ọma na nyocha nke elu ọkpọkọ iji wepụ ihe ọ bụla na-emerụ emerụ ma ọ bụ ntụpọ nwere ike imetụta àgwà nke weld.Na mgbakwunye, iji nweta weld siri ike ma bụrụ nke a pụrụ ịdabere na ya, a ga-atụrịrị ọkpọkọ nke ọma ma kwekọọ.
N'oge usoro ịgbado ọkụ n'ezie, nlebara anya na nkọwa zuru oke na ịgbaso usoro ziri ezi dị oke mkpa.Ịhọrọ usoro ịgbado ọkụ kwesịrị ekwesị, ma TIG (tungsten inert gas welding), MIG (metal inert gas welding) ma ọ bụ SMAW (stick arc welding), ga-ahọrọ dabere na ihe achọrọ maka ntinye pipeline gas.Na mgbakwunye, iji ihe ndochi dị elu yana usoro ịgbado ọkụ nke ọma dị oke mkpa maka imepụta welds a pụrụ ịdabere na ya na nke na-adịgide adịgide nke na-emezu ihe achọrọ nke ọrụ pipeline gas.
Na mgbakwunye, nyocha na nyocha weld post-weld bụ usoro dị mkpa iji hụ na ịdị mma weld na iguzosi ike n'ezi ihe na nrụnye pipeline gas site na iji SSAW ígwè ọkpọkọ.Ụzọ nnwale na-adịghị emebi emebi, dị ka nyocha redio na nyocha ultrasonic, nwere ike inye aka chọpụta ntụpọ ọ bụla nwere ike ime ma ọ bụ nkwụsị na nkwonkwo welded ka e wee dozie ha ngwa ngwa ma hụ na ntụkwasị obi nke sistemu ọkpọkọ gas gị.
Na nchịkọta, usoro ịgbado ọkụ ziri ezi dị oke mkpa maka ịwụnye ahịrị gas site na iji spiral submerged arc welded steel pipe.Iguzosi ike n'ezi ihe na nchekwa nke sistemụ ọkpọkọ gas gị na-adabere n'ịdị mma nke ịgbado ọkụ gị, ya mere a ga-agbaso ụkpụrụ ụlọ ọrụ ịgbado ọkụ na omume kacha mma.Site n'ịkwado nkwadebe tupu weld kwesịrị ekwesị, usoro ịgbado ọkụ nke ọma, na nyocha nke ọma mgbe weld, ndị na-etinye ọkpọkọ gas nwere ike hụ na ntụkwasị obi na nchekwa nke nrụnye ọkpọ ígwè SSAW maka ngwa ọkpọkọ gas.
