Ityhubhu yesikwere esenziwe ngesinyithi kunye netyhubhu exande

Galvanized square tube & rectangular tube Featured Image

Inkcazelo emfutshane:

Umbhobho we-galvanized rectangular ligama lombhobho wesikwere kunye nombhobho wexande, oko kukuthi, imibhobho yentsimbi enobude obulinganayo.Yenziwe nge-rolling strip yentsimbi emva konyango lwenkqubo.Ngokuqhelekileyo, intsimbi yentsimbi ayipakishwanga, icwecwe, ikhutshiwe, kwaye idityaniswe ukuze yenze ityhubhu ejikelezayo, emva koko ityhubhu ejikelezayo idityaniswe kwityhubhu yesikwere kwaye isikwe kubude obufunekayo.Ngokuqhelekileyo amaqhekeza angama-50 ngepakethi.Ikwabizwa ngokuba sisikweri kunye noxande obumba intsimbi yecandelo elinomngxuma, elifinyeziweyo njengetyhubhu yesikwere kunye netyhubhu exande, iikhowudi nguF kunye noJ ngokulandelelanayo.

Iinkcukacha zeMveliso

Iithegi zeMveliso

1. Ukutenxa okuvumelekileyo kobunzima bodonga lwetyhubhu ye-galvanized rectangular akusayi kudlula ukudibanisa okanye ukuthabatha i-10% yobukhulu bodonga oluqhelekileyo xa ubukhulu bodonga bungaphantsi kwe-10mm, kwaye xa ubukhulu bodonga bungaphezulu kwe-10mm, kudibanisa okanye thabatha i-8% yobukhulu bodonga.Ngaphandle kobunzima bodonga kwindawo yomthungo.

2. Ubude obuqhelekileyo bokuhanjiswa kwetyhubhu ye-galvanized rectangular yi-4000mm-12000mm, ininzi i-6000mm kunye ne-12000mm.Iipayipi ezixande zivunyelwe ukuhambisa ubude obufutshane kunye neemveliso ezingaguqukiyo ezingekho ngaphantsi kwe-2000mm, kwaye zinokuhanjiswa ngendlela yemibhobho ye-interface, kodwa umthengi kufuneka anqumle umbhobho wokudibanisa xa usebenzisa.Ubunzima beemveliso ezinobude obufutshane kunye nobude obungaguqukiyo akufanele budlule i-5% yomthamo opheleleyo wokuhanjiswa, kunye neetyhubhu zesikwere esixande ezinobunzima obungaphezu kwe-20kg / m, akufanele idlule i-10% yomthamo wokuhanjiswa. .

3. I-curvature yombhobho we-galvanized rectangular ayiyi kuba mkhulu kune-2mm ngemitha nganye, kwaye i-curvature iyonke ayiyi kuba ngaphezu kwe-0.2% yobude obupheleleyo.

Intshayelelo yoHlelo

1. Ukuhlelwa kwenkqubo yokuvelisa umbhobho wexande
Iityhubhu ezixande zihlelwa ngokwenkqubo yemveliso: iityhubhu ezisikweri ezingenamthungo ezishushu eziqengqelekayo, iityhubhu zesikwere ezingenamthungo ezitsalwa ngokubanda, iityhubhu zesikwere ezingenamthungo, kunye netyhubhu edityanisiweyo yesikwere.Phakathi kwazo, umbhobho odityanisiweyo wesikweri wahlulwe waba: (a) Ngokwenkqubo-i-arc welding square pipe, ukumelana ne-welding square pipe (i-frequency ephezulu, i-frequency ephantsi), i-gas welding square pipe, i-furnace welding square pipe (b) i-weld-straight Seam welded square pipe, spiral welded square pipe

2. Ukuhlelwa kwezinto eziphathekayo ityhubhu yoxande
Imibhobho yesikwere ihlelwa ngokwezinto zabo: iipayipi ze-carbon steel square kunye ne-low-alloy square pipes.Intsimbi yekhabhoni eqhelekileyo yahlulwe: Q195, Q215, Q235, SS400, 20 # intsimbi, 45 # intsimbi, njl.;intsimbi ephantsi ye-alloy yahlulwe kwi-Q345, 16Mn, Q390, ST52-3, njl.

3. Ukuhlelwa okusemgangathweni kokuveliswa kweetyhubhu ezixande
Imibhobho yesikwere ihlelwa ngokwemigangatho yemveliso: imibhobho yesikwere esemgangathweni yesizwe, imibhobho yesikwere esemgangathweni yaseJapan, imibhobho yesikwere yobukhosi, imibhobho yesikwere esemgangathweni yaseMelika, imibhobho yesikwere esemgangathweni yaseYurophu, kunye nemibhobho yesikwere engaqhelekanga.

4. Ukuhlelwa kwemilo yecandelo lombhobho wexande
Imibhobho yesikwere yahlulahlulwe ngokweemilo zayo ezinqamlezileyo: (1) imibhobho yesikwere enqamlezileyo elula, imibhobho esisikwere esisikweri, imibhobho esisikwere esixande (2) imibhobho enqamlezileyo entsonkothileyo-emile okwentyatyambo. , imibhobho yesikwere edibeneyo, imibhobho yesikwere enemilo ekhethekileyo

5. Ukuhlelwa konyango lomphezulu wombhobho wexande
Imibhobho yesikwere yahlulahlulwe ibe lunyango lomphezulu: idiphu eshushu-dip yesikwere imibhobho, i-electro-galvanized square pipes, i-oyile-coated square pipes, pickled square pipes.

6. Sebenzisa ukuhlelwa kombhobho wexande
Imibhobho yesikwere ihlelwa ngokwenjongo-isikwere imibhobho yokuhombisa, imibhobho yesikwere yezixhobo zoomatshini, imibhobho yesikwere yoshishino loomatshini, imibhobho yesikwere yoshishino lweekhemikhali, imibhobho yesikwere yezakhiwo zentsimbi, imibhobho yesikwere yokwakha inqanawa, imibhobho yesikwere yemoto, imibhobho yesikwere yentsimbi. imiqadi kunye neentsika Ityhubhu, injongo ekhethekileyo ityhubhu yesikwere

7. Ukuhlelwa kobunzima bodonga lwetyhubhu yoxande
Imibhobho yoxande ihlelwa ngobungqingqwa bodonga-umbhobho woxande otyebileyo kakhulu, imibhobho yoxande enodonga olungqingqwa kunye nemibhobho ebhityileyo enoxande.

Sebenzisa

Isetyenziswa kakhulu kwiindonga zamakhethini, ukwakhiwa, ukuveliswa koomatshini, iiprojekthi zokwakha isinyithi, ukwakhiwa kweenqanawa, izibiyeli zokuvelisa amandla elanga, ubunjineli besakhiwo sentsimbi, ubunjineli bamandla, izityalo zamandla, oomatshini bezolimo kunye neekhemikhali, iindonga zamakhethini eglasi, i-chassis yemoto, izikhululo zeenqwelo moya, njl.
