Ukulethwa okusheshayo Ikhwalithi Ephakeme Engenamthungo Ye-Carbon Steel Boiler Tube/Pipe ASTM A192
Siphikelela ekunikezeni isizukulwane sekhwalithi enhle enomqondo omuhle kakhulu webhizinisi, imali engenayo ethembekile kanye nosizo olungcono kakhulu nolusheshayo. ngeke ikulethele kuphela umkhiqizo noma isevisi yekhwalithi ephezulu kanye nenzuzo enkulu, kodwa mhlawumbe okubaluleke kakhulu ngokuvamile ukuhlala emakethe engapheli yokulethwa okusheshayo Ikhwalithi Ephakeme Engenamthungo Ye-Carbon Steel Boiler Tube/PipeI-ASTM A192, Kusukela iyunithi yokukhiqiza yasungulwa, manje sesizinikele ekuqhubekeleni phambili kwezimpahla ezintsha. Ngokuhambisana nesivinini senhlalo nezomnotho, sizoqhubeka nokuqhubekisela phambili umoya “wokuseqophelweni eliphezulu, ukusebenza kahle, ukusungula izinto ezintsha, ubuqotho”, futhi sihlale nomgomo wokusebenza “wesikweletu ekuqaleni, ikhasimende lokuqala, izinga elihle kakhulu”. Sizokhiqiza ikusasa elihle kakhulu elibonakalayo ekuphumeni kwezinwele nabangane bethu.

Uma unentshisekelo kokuthengiswayo kwethu, akufanele ungangabazi ukusithinta ukuze uthole ulwazi olwengeziwe.
Uhlolojikelele
Isicelo
Isetshenziswa kakhulu ukwenza ipayipi lensimbi ye-alloy esezingeni eliphakeme yepayipi le-boiler elicindezela kakhulu, ipayipi lokushintshanisa ukushisa kanye nepayipi lokushisa eliphakeme.
Ibanga Eliyinhloko
Ibanga eliphezulu lensimbi ye-Alloy: T2, T12, T11, T22, T91, T92 njll.
