Kumashubhu ensimbi angu-20# anobukhulu bodonga obufika ku-87mm, ubuqotho bangaphakathi bubaluleke kakhulu, njengoba ngisho nemifantu emincane nokungcola kungase kubeke engcupheni ubuqotho nokusebenza kwazo kwesakhiwo, futhi ukuhlolwa kwe-ultrasonic kungabona ngempumelelo la maphutha angenzeka.
Ukuhlolwa kwe-Ultrasonic, okubuye kubizwe ngokuthi yi-UT, kuyindlela yokuhlola engabhubhisi esebenzisa izakhiwo zokubonisa, ukuphindaphinda, kanye nokuncishiswa kwamagagasi e-ultrasonic njengoba ebhebhetheka ngento ukuze athole amaphutha ngaphakathi kwempahla.
Lapho i-wave ye-ultrasonic ihlangabezana nokukhubazeka ngaphakathi kwempahla efana nokuqhekeka, okufakiwe noma izimbobo, amagagasi abonisiwe azokhiqizwa, futhi indawo, ukwakheka kanye nobukhulu bezinkinga kunganqunywa ngokuthola lawa maza abonisiwe.
Ngokuhlola ngokucophelela, iqinisekisa ukuthi ipayipi lensimbi jikelele alinawo amaphutha futhi lihambisana ngokugcwele nezindinganiso kanye nezidingo zamakhasimende.
I-Botop ingumkhiqizi wamapayipi ensimbi ashiselwe futhi onokwethenjelwa kanye nesitokwe se-Seamless Steel Pipe e-China, ikunikeza imikhiqizo yamapayipi ensimbi enekhwalithi ethembekile kanye nenani elincintisanayo. Sithembisa ukusekela inhlangano yesithathu yokuhlola zonke izimpahla esizithengisayo, futhi sizohlela abahloli ukuthi bahlole amapayipi ensimbi futhi lapho iqoqo ngalinye lamapayipi ensimbi lilethwa ukuze kuqinisekiswe ikhwalithi yamapayipi ensimbi futhi.
I-GB/T 8162 iyisimiso esijwayelekile esikhishwe yi-Chinaamapayipi ensimbi angenamthungongezinhloso zesakhiwo. I-20 # iyibanga elivamile le-carbon steel elinezinto ezinhle zemishini nokucubungula, ezisetshenziswa kabanzi ekwakheni izakhiwo kanye nezakhiwo zemishini.
I-GB/T 8162 yeBanga lama-20 ukwakheka kwamakhemikhali kanye nezidingo zezakhiwo eziwumshini zimi kanje:
I-GB/T 8162 Ibanga lama-20 Ukwakheka Kwamakhemikhali:
