Galvanized steel pipepombi yesimbi yakagadzirwa nekunamira zingi pamusoro pepombi yesimbi yakajairika (kabhoni simbi pombi). Zinc ine maitiro emakemikari anoshanda uye inogona kuumba dense oxide firimu, nekudaro ichiparadzanisa okisijeni uye mwando uye kudzivirira pombi yesimbi kubva kuita ngura.GI simbi pombiipombi yesimbi ine zingi inonamira pamusoro pepombi yakajairika yesimbi kudzivirira ngura. Yakakamurwa kuita inopisa-dip galvanizing uye electro-galvanizing. Hot-dipmapaipi esimbivanonyudzwa mumvura yakanyungudutswa yezinc (inenge 450 ° C) kuti iite zinc layer yakakora (50-150μm), ine simba rekudzivirira kusvibiswa uye inokodzera nzvimbo dzekunze kana dzakanyorova; electro-galvanized simbi pombi inotora electrolysis process, iyo zinc layer itete (5-30μm), mutengo wakaderera, uye unonyanya kushandiswa mukati memba.

Zvinyorwa zveGarivanized Steel Pipe

Saizi uye Diameter

1.Nominal dhayamita (DN): The common range is DN15 ~ DN600 (kureva 1/2 inch ~ 24 inches).

2.Outer dhayamita (OD):

(1).Small dhayamita nyere: akadai DN15 (21.3mm), DN20 (26.9mm).

(2) .Medium uye hombe dhayamita nyere: akadai DN100 (114.3mm), DN200 (219.1mm).

3.British tsanangudzo: Zvimwe zvichiri kuratidzwa mumasendimita, zvakadai se 1/2 ", 3/4", 1 ", nezvimwewo.

Wall Thickness And Pressure Rating

1.Ordinary wall thickness (SCH40): yakakodzera kune yakaderera-inodzvinyirira mvura yekufambisa (yakadai semapombi emvura, gasi pombi).

2.Thickened wall thickness (SCH80): kupikisa kwepamusoro-soro, kushandiswa kwekutsigirwa kwemaitiro kana zviitiko zvepamusoro.

3.National mwero rusvingo ukobvu: Sezvakatsanangurwa muna GB/T 3091, rusvingo ukobvu DN20 kwakakurudzira simbi pombi iri 2.8mm (yakajairika giredhi).

Urefu

1.Standard urefu: kazhinji 6 mamita / chidimbu, 3m, 9m kana 12m inogonawo kugadziriswa.

2.Fixed urefu: kutema maererano nezvinodiwa zvepurojekiti, ± 10mm kukanganisa kunobvumirwa.

Materials And Standards

1.Base pombi zvinhu:Q235 carbon simbi, Q345 yakaderera alloy simbi, nezvimwe.

2.Galvanized layer ukobvu:

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

(2) .Electrogalvanizing: 5 ~ 30μm (isina simba ngura).

3.Implementation zviyero:

(1) .China: GB/T 3091 (weld galvanized pipe), GB/T 13793 (seamless galvanized pipe).

(2).International: ASTM A53 (American standard), EN 10240 (European standard).

Galvanized Steel Pipe Welding Process

Saizi uye Diameter

Welding nzira: Inowanzo shandiswa welding nzira dzinosanganisira manual arc welding, gasi shielded welding, CO2 gasi shielded welding, nezvimwewo.

Kugadzirira kweWelding: Usati waputira, zvakasvibiswa pamusoro pepende, ngura uye tsvina munzvimbo yewelding zvinoda kubviswa kuti zvive nechokwadi chehutano hweweld.

Welding process: Panguva yewelding, iyo yazvino, voltage uye welding kumhanya kunofanirwa kudzorwa kudzivirira matambudziko akadai se undercut uye isina kukwana kupinda. Mushure mekuputika, kutonhora uye kutema kunofanira kuitwa kudzivirira deformation uye kuputika.

Kudzora kwehutano: Panguva yekuputika, kutarisa kunofanira kubhadharwa kune flatness uye kutsetseka kweweld kudzivirira kukanganisa kwakadai se pores uye slag inclusions. Kana welding quality matambudziko akawanikwa, anofanira kubatwa uye kugadziriswa nenguva.

Kushandiswa kweGarivanized Steel Pipe

Kuvaka Uye Chimiro Injiniya

1.Kuvaka scaffolding

Shandisa: kutsigirwa kwenguva pfupi kwekuvaka, kunze kwemadziro ekushanda papuratifomu.

Zvinotsanangurwa: DN40~DN150, rusvingo ukobvu ≥3.0mm (SCH40).

Zvakanakira: simba rakakwirira, nyore disassembly uye gungano, rinoramba kuita ngura pane zvakajairika simbi pombi.

2.Steel chimiro chekubatsira zvikamu
Shandisa: stair handrails, matanda edenga, mbiru dzefenzi.

Zvimiro: Surface galvanizing inogona kushandiswa kunze kwenguva yakareba, kuderedza mari yekugadzirisa.

3. Kuvaka drainage system
