Umbhobho wentsimbi owenziwe ngamachizangumbhobho wensimbi owenziwe ngokugquma umaleko we-zinc phezu kombhobho wentsimbi oqhelekileyo (umbhobho we-carbon steel). I-Zinc ineempawu zeekhemikhali ezisebenzayo kwaye inokwenza ifilimu ye-oxide exineneyo, ngaloo ndlela ihlukanise i-oksijini kunye nomswakama kunye nokuthintela umbhobho wensimbi ukuba ungagqwali.Umbhobho wentsimbi we-GIngumbhobho wesinyithi kunye ne-zinc yokubeka phezu kombhobho wentsimbi oqhelekileyo ukukhusela ukubola. Yahlulwe ibe yi-galvanizing eshushu-dip kunye ne-electro-galvanizing. Ishushu-dipimibhobho yentsimbibantywiliselwe kulwelo lwezinki olunyibilikisiweyo (malunga nama-450°C) ukuze benze umaleko we-zinc ongqindilili (50-150μm), onokumelana ne-corrosion eyomeleleyo kwaye ifanele iindawo ezingaphandle okanye ezifumileyo; i-electro-galvanized steel pipe ithatha inkqubo ye-electrolysis, i-zinc layer iyancipha (5-30μm), ixabiso liphantsi, kwaye lisetyenziswa kakhulu ngaphakathi.

Iinkcukacha zoMbhobho weNtsimbi

Ubungakanani kunye nobubanzi

1.I-diameter ye-Nominal (DN): Uluhlu oluqhelekileyo yi-DN15 ~ DN600 (okt 1/2 intshi ~ 24 intshi).

2.Idayimitha yangaphandle (OD):

(1).Umbhobho wedayamitha omncinci: njenge-DN15 (21.3mm), DN20 (26.9mm).

(2) .Phakathi kunye nedayamitha enkulu umbhobho: ezifana DN100 (114.3mm), DN200 (219.1mm).

I-3.Iinkcazo zaseBritani: Ezinye zisabonakaliswa ngee-intshi, ezifana ne-1/2 ", 3/4", 1", njl.

Ukutyeba kweendonga kunye noxinzelelo loxinzelelo

I-1.I-Ordinary wall thickness (SCH40): ilungele ukuthuthwa kwamanzi okuphantsi koxinzelelo (njengemibhobho yamanzi, iipayipi zegesi).

I-2.I-Thickened wall thickness (SCH80): ukumelana noxinzelelo oluphezulu, olusetyenziselwa ukuxhaswa kwesakhiwo okanye iimeko zoxinzelelo oluphezulu.

I-3.Ubukhulu bodonga oluqhelekileyo lweSizwe: Njengoko kucacisiwe kwi-GB / T 3091, ubukhulu bodonga lwe-DN20 umbhobho wensimbi owenziwe ngamatye yi-2.8mm (ibakala eliqhelekileyo).

Ubude

1.Ubude obuqhelekileyo: ngokuqhelekileyo iimitha ezi-6 / iqhekeza, i-3m, i-9m okanye i-12m nayo inokwenziwa ngokwezifiso.

2.Ubude obulungisiweyo: ukusika ngokweemfuno zeprojekthi, i-± 10mm impazamo ivumelekile.

Izixhobo kunye neMigangatho

1.Isiseko semathiriyeli yombhobho:Q235 carbon steel, Q345 intsimbi ephantsi ye-alloy, njl.

2. Umaleko owenziwe ngegalvanized:

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

(2) .I-Electrogalvanizing: 5 ~ 30μm (i-rust resistance resistance).

3.Imigangatho yokuphunyezwa:

(1) .China: I-GB / T 3091 (umbhobho we-galvanized welding), i-GB / T 13793 (umbhobho we-galvanized ongenamthungo).

(2) .International: ASTM A53 (umgangatho waseMelika), EN 10240 (umgangatho waseYurophu).

Inkqubo yokuWelding yentsimbi yombhobho weGalvanized

Ubungakanani kunye nobubanzi

Indlela ye-Welding: Iindlela ezisetyenziswa ngokuqhelekileyo zibandakanya i-arc welding manual, i-gas shielded welding, i-CO2 ye-gas shielded welding, njl. Ukukhetha indlela efanelekileyo yokudibanisa kunokuphucula umgangatho we-welding.

Ukulungiswa kwe-Welding: Ngaphambi kwe-welding, ukungcola komhlaba okufana nepeyinti, i-rust kunye nokungcola kwindawo ye-welding kufuneka isuswe ukuze kuqinisekiswe umgangatho we-weld.

Inkqubo ye-Welding: Ngexesha le-welding, i-current, i-voltage kunye ne-welding speed kufuneka ilawulwe ukuphepha iingxaki ezifana nokungena ngaphantsi kunye nokungena okungaphelelanga. Emva kwe-welding, ukupholisa kunye nokunciphisa kufuneka kuqhutywe ukukhusela i-deformation kunye nokuqhekeka.

Ukulawulwa komgangatho: Ngexesha le-welding, ingqalelo kufuneka ihlawulwe kwi-flatness kunye ne-smooth ye-weld ukuphepha iziphene ezifana ne-pores kunye ne-slag inclusions. Ukuba iingxaki zomgangatho we-welding zifunyenwe, kufuneka ziphathwe kwaye zilungiswe ngexesha elifanelekileyo.
