Iningi amapayipi square kukhona amapayipi ensimbi, kanyeamapayipi ayisikwele angama-hot-dipzimbozwe ungqimba lwe-zinc ebusweni bamapayipi ensimbi ngenqubo ekhethekile. Okulandelayo, sizochaza ngokuningiliziwe ukuthi singayixazulula kanjani inkinga yokugqwala kwamapayipi esikwele angama-galvanized.
Isinyathelo sokuqala ukungqongqoza: ukuze wenze inathi lixegeke kalula, kuyadingeka ukuthi ungqongqoze kancane ipayipi eligqwalile le-304 elingenamthungo eliyisikwele ngesando esiphezulu esiyisikwele. Imboni yamapayipi ayisikwele enziwe uthayela kufanele inqwabelanise ulwazi ngokunengqondo. Uma i-nati iyinsimbi ephonswe, idinga ukuba nzima kancane. Ipayipi eliyisikwele le-Q345B nezingxenye zepulasitiki ezijwayelekile zidinga kuphela ukungqongqozwa kahle. Uma kungenjalo, sebenzisa isando ukuze ujikelezise lapho ushaya khona ku-304ipayipi eliyisikwele elingenamthungo.
Isinyathelo sesi-2: ungasebenzisi isikrufu ukuze usikulule esiqinile isikulufu sensimbi egqwalile ukuze ugweme ukuphula isikulufu sensimbi engagqwali noma ukulimaza isikrufu. Ngalesi sikhathi, kuyadingeka ukusebenzisa isando sensimbi ukuze unyakazise isibambo se-wrench ukuze izikulufu zensimbi egqwalile zingavulwa kalula.
Isinyathelo sesithathu ukubhoboza: ngesinye isikhathi ipayipi lesikwele elingenamthungo elingu-304 lizokhubazeka ngenxa yokugqwala. Ipayipi eliyisikwele elinothayela - ipayipi lesikwele elinothayela - ipayipi eliyisikwele elishisayo - ifektri yamapayipi esikwele esiphekiweI-Tianjin galvanized square pipe factoryayikwazi ukuyisusa ngesikrufu noma isikrufu socingo. Ngalesi sikhathi, "indlela yethonya" isetshenziswa. Iyini "indlela yethonya"? Izothinta "umsele omise okwe-U" ohlangothini oluqondile phezulu kwepayipi eliyisikwele elingenamthungo elingu-304 ngesando sensimbi kanye nesando sophephela. Ifekthri yepayipi eliyisikwele elinothayela kufanele ibeke ulwazi ngokunengqondo bese ilungisa i-engeli yekhoni yokubhoboza. Ipayipi eliyisikwele le-Q345B eliyisikwele lingakhishwa ngemuva kokuthi uwoyela ungene.
Isinyathelo sesine siyavutha: lapho i-304 engenamthungo ifaka uthayelaipayipi lesikweleigqwalile, futhi ayikho kulezi zindlela ezingenhla esebenzayo, indlela "yokuhlasela ngomlilo" izokwamukelwa. Manje, izikulufi namantongomane zosiwe nge-gas welding oxidation flame. Ngemva kokuba ubuso bushiswe bubomvu, amafutha amancane ayawa. Indlela "yokwandisa okushisayo nokufinyela okubandayo" yamukelwa ukuze kwandiswe igebe phakathi kwenduku yesikulufa kanye nepayipi lesikwele elingenamthungo elingama-304. Ipayipi eligqwalile elingu-304 elingenamthungo eliyisikwele lingakhishwa isikulufu ngemva kokungena kukawoyela.
