Ipayipi lensimbi eliphehliweipayipi lensimbi elenziwe ngokumboza ungqimba lwezinc ebusweni bepayipi elivamile lensimbi (ipayipi lensimbi ye-carbon). I-Zinc inamakhemikhali asebenzayo futhi ingakha ifilimu ye-oxide eminyene, ngaleyo ndlela ihlukanise umoya-mpilo nomswakama futhi ivimbele ipayipi lensimbi ukuthi lingagqwali.Ipayipi yensimbi ye-GIiyipayipi yensimbi ene-zinc enamathela phezu kwepayipi elivamile lensimbi ukuvimbela ukugqwala. Ihlukaniswe yaba i-hot-dip galvanizing kanye ne-electro-galvanizing. I-Hot-dipamapayipi ensimbibacwiliswa oketshezini lwezinki oluncibilikisiwe (cishe u-450°C) ukuze bakhe ungqimba lwezinc olujiyile (50-150μm), olunokumelana nokugqwala okuqinile futhi lufanele indawo yangaphandle noma enomswakama; Ipayipi lensimbi elenziwe nge-electro-galvanized lamukela inqubo ye-electrolysis, isendlalelo se-zinc mncane (5-30μm), izindleko ziphansi, futhi isetshenziswa kakhulu endlini.

Imininingwane Yepayipi Elikhandiwe Lensimbi

Usayizi Nobubanzi

1.Ububanzi begama (DN): Ibanga elijwayelekile lithi DN15 ~ DN600 (okungukuthi 1/2 intshi ~ 24 amayintshi).

2.Ububanzi bangaphandle (OD):

(1).Ipayipi lobubanzi obuncane: njenge-DN15 (21.3mm), DN20 (26.9mm).

(2).Ipayipi lobubanzi obuphakathi nendawo elikhulu: njenge-DN100 (114.3mm), DN200 (219.1mm).

3.Izincazelo zaseBrithani: Ezinye zisavezwa ngamayintshi, njengokuthi 1/2", 3/4", 1", njll.

Ukuqina Kwezindonga Nezilinganiso Zokucindezela

I-1.I-Ordinary wall thickness (SCH40): ifanele ukuthuthwa kwamanzi okucindezela okuphansi (njengamapayipi amanzi, amapayipi egesi).

I-2.I-Thickened wall thickness (SCH80): ukumelana nokucindezela okuphezulu, okusetshenziselwa ukusekelwa kwesakhiwo noma izimo zokucindezela okuphezulu.

3.Ukujiya kodonga olujwayelekile kuzwelonke: Njengoba kucaciswe ku-GB/T 3091, ubukhulu bodonga lwepayipi lensimbi elithathiwe le-DN20 lingu-2.8mm (ibanga elivamile).

Ubude

1.Ubude obujwayelekile: ngokuvamile amamitha angu-6/piece, 3m, 9m noma 12m nakho kungenziwa ngezifiso.

I-2.Ubude obulungisiwe: ukusika ngokuvumelana nezidingo zephrojekthi, iphutha le-± 10mm livunyelwe.

Izinto kanye Namazinga

1.Impahla yepayipi yesisekelo:Q235 carbon steel, Q345 low alloy steel, njll.

2.Ugqinsi lwesendlalelo esiphehliwe:

(1).I-Hot-dip galvanizing: ≥65μm (GB/T 3091).

(2) .I-Electrogalvanizing: 5~30μm (ukumelana nokugqwala okubuthakathaka).

3.Amazinga okusebenzisa:

(1).I-China: I-GB/T 3091 (ipayipi elinothayela elishiselwe), i-GB/T 13793 (ipayipi elinothayela elingenamthungo).

(2).Okwamazwe ngamazwe: ASTM A53 (Izinga laseMelika), EN 10240 (Izinga laseYurophu).

Inqubo Yokushisela Ipayipi Lensimbi Elivunyiwe

Usayizi Nobubanzi

Indlela yokushisela: Izindlela zokushisela ezivame ukusetshenziswa zifaka i-arc welding manual, i-gas shielded welding, i-CO2 yegesi evikelekile ye-welding, njll. Ukukhetha indlela yokufaka i-welding efanele kungathuthukisa ikhwalithi ye-welding.

Ukulungiswa kokushisela: Ngaphambi kokushisela, ukungcola okungaphezulu okufana nopende, ukugqwala nokungcola endaweni yokushisela kudingeka kususwe ukuze kuqinisekiswe izinga le-weld.

Inqubo yokushisela: Ngesikhathi sokushisela, ijubane lamanje, i-voltage kanye ne-welding kufanele ilawulwe ukuze kugwenywe izinkinga ezifana nokungena ngaphansi nokungena okungaphelele. Ngemuva kwe-welding, ukupholisa nokusikwa kufanele kwenziwe ukuvimbela ukuguquguquka nokuqhekeka.

Ukulawulwa kwekhwalithi: Ngesikhathi sokushisela, ukunakwa kufanele kukhokhwe ekubangeni kanye nokushelela kwe-weld ukugwema amaphutha afana nama-pores kanye ne-slag inclusions. Uma izinkinga zekhwalithi yokushisela zitholakala, kufanele ziphathwe futhi zilungiswe ngesikhathi.

Ukusetshenziswa Kwepayipi Lensimbi Elikhandiwe

Ubunjiniyela Bokwakha Nokwakha
