Umehluko phakathi kwepayipi lensimbi elakhiwe ngaphambili kanye ne-hot-dip, indlela yokuhlola ikhwalithi yayo?

Umehluko phakathiipayipi pre-galvanizedfuthiIpayipi Lensimbi Elinothayela Elishisayo-DIP

1. Umehluko enqubweni: Ipayipi elinothayela elishisayo lifakwa ipayipi ngokucwilisa ipayipi lensimbi kuzinc encibilikisiwe, kuyilapho.ipayipi pre-galvanizedihlanganiswe ngokulinganayo nge-zinc ebusweni bomucu wensimbi ngenqubo ye-electroplating.

2. Umehluko wesakhiwo: Ipayipi likathayela le-hot-dip liwumkhiqizo we-tubular, kuyilapho ipayipi lensimbi elakhiwe ngaphambilini liwumkhiqizo odwetshwayo onobubanzi obukhulu kanye nogqinsi oluncane.

3. Izinhlelo zokusebenza ezehlukene: Amapayipi ashisayo asetshenziswa kakhulu ukuthutha uketshezi namagesi, njengamapayipi okuhambisa amanzi, amapayipi kawoyela, njll., kuyilapho amapayipi ensimbi afakwe ngaphambili asetshenziswa ikakhulukazi ukukhiqiza imikhiqizo ehlukahlukene yensimbi, njengezingxenye zezimoto, ikhaya. amagobolondo kagesi nokunye.

4. Ukusebenza okuhlukile kokunqanda ukugqwala: ipayipi likathayela elicwiliswayo elishisayo linokusebenza okungcono kokunqanda ukugqwala ngenxa yongqimba oluqinile lukathayela, kuyilapho umugqa wensimbi ewuthayela usebenza kabi uma kuqhathaniswa nokugqwala ngenxa yongqimba oluncane lukathayela.

5. Izindleko ezihlukene: inqubo yokukhiqiza ipayipi elifakwe emanzini ashisayo liyinkimbinkimbi futhi liyabiza, kuyilapho inqubo yokukhiqiza ipayipi lensimbi elithambile ilula futhi ibiza kancane.

Ukuhlolwa kwekhwalithi yamapayipi ensimbi enakekelwe ngaphambili kanye nediphu eshisayo
1. Ukuhlolwa kokubukeka
Ukuqedwa kobuso: Ukuhlolwa kokubukeka kugxile kakhulu ekutheni ingabe ingaphezulu lepayipi lensimbi liyisicaba futhi libushelelezi, ngaphandle kwe-zinc slag esobala, isimila se-zinc, ukugeleza okulenga noma okunye ukonakala kwendawo. Indawo enhle yepayipi lensimbi eyisivikelo kufanele ibe bushelelezi, ingabi namabhamuza, ingabi nemifantu, ingabi namathumba e-zinc noma ukugeleza kwe-zinc okulengayo nokunye ukukhubazeka.

Umbala nokufana: Hlola ukuthi umbala wepayipi lensimbi ufana futhi awuguquki, nokuthi ingabe kukhona ukusatshalaliswa okungalingani kwesendlalelo se-zinc, ikakhulukazi emithumeni noma ezindaweni ezishiselwe. Ipayipi lensimbi elicwebezelayo elidiphu elishisayo ngokuvamile libonakala limhlophe njengesiliva noma lingekho mhlophe, kuyilapho ipayipi lensimbi elakhiwe ngaphambili lingase libelula kancane ngombala.

2. Isilinganiso sokuqina kweZinc
I-Thickness Gauge: Ukujiya kongqimba lwezinki kukalwa kusetshenziswa igeji yokujiya emboziwe (isb. magnetic noma eddy current). Lesi yinkomba eyinhloko yokunquma ukuthi i-zinc coating ihlangabezana nezidingo ezijwayelekile. Ipayipi lensimbi elidiphu elishisayo livamise ukuba nongqimba lwezinki olujiyile, ngokuvamile oluphakathi kwama-microns angu-60-120, futhi ipayipi lensimbi elakhiwe ngaphambilini linongqimba oluncane lwezinki, ngokuvamile oluphakathi kwama-microns angu-15-30.

Indlela yesisindo (isampula): Amasampula akalwa ngokwezinga futhi isisindo sesendlalelo se-zinc endaweni yeyunithi ngayinye sibalwa ukuze kunqunywe ukushuba kongqimba lwezinc. Lokhu kuvame ukunqunywa ngokulinganisa isisindo sepayipi ngemva kokukhetha.

Izidingo ezijwayelekile: Isibonelo, i-GB/T 13912, i-ASTM A123 nezinye izindinganiso zinezidingo ezicacile zogqinsi lwesendlalelo se-zinc, futhi izidingo zogqinsi lwezinki zamapayipi ensimbi ezisetshenziswa ezahlukene zingahluka.

3. Ukufana kwesendlalelo esinothayela
Isendlalelo samagalazi sekhwalithi ephezulu siyafana ekuthunjweni, akukho ukuvuza futhi akukho monakalo wokunamathisela okuthunyelwe.

Akukho ukuwoza okubomvu okutholakala ngemva kokuhlolwa ngesisombululo se-copper sulfate, okubonisa ukuthi akukho ukuvuza noma ukulimala kwangemva kokucwenga.

Leli izinga eliphezulu lokufakwa kwamagalani ukuze kuqinisekiswe ukusebenza kahle nokubukeka.

4. Ukunamathela okuqinile kwesendlalelo sama-galvanized
Ukunamathela kwesendlalelo se-galvanized kuyinkomba ebalulekile yekhwalithi yepayipi yensimbi, ebonisa izinga lokuqina kwenhlanganisela phakathi kwesendlalelo se-galvanized kanye nepayipi yensimbi.

Ipayipi lensimbi lizokwenza ungqimba oluxubile lwe-zinc nensimbi nesisombululo se-galvanizing ngemva kokusabela kokugeza okucwiliswayo, futhi ukunamathela kongqimba lwe-zinc kungathuthukiswa yinqubo yesayensi nenembile.

Uma ungqimba lwe-zinc lungasuki kalula lapho luthelwa nge-mallet yerabha, lubonisa ukunamathela okuhle.
