Ityhubhu yesikwere esenziwe ngesinyithi kunye netyhubhu exande

Ityhubhu yesikwere esenziwe ngesinyithi kunye netyhubhu yoxande Umfanekiso obonakalayo

Inkcazelo emfutshane:

Umbhobho we-galvanized rectangular ligama lombhobho wesikwere kunye nombhobho wexande, oko kukuthi, imibhobho yentsimbi enobude obulinganayo. Yenziwe ngokuqengqeleka komgca wentsimbi emva konyango lwenkqubo. Ngokuqhelekileyo, intsimbi ye-strip ayipakishwa, icwecwe, ifakwe i-crimp, kwaye idityaniswe ukuze yenze ityhubhu ejikelezayo, emva koko ityhubhu ejikelezayo ihlanganiswe kwityhubhu yesikwere kwaye inqunywe ubude 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 akuyi kudlula ukudibanisa okanye ukukhupha i-10% yobukhulu bodonga oluqhelekileyo xa ubuninzi bodonga bungaphantsi kwe-10mm, kwaye xa ubukhulu bodonga bukhulu kune-10mm, kudibanisa okanye thabatha i-8% yodonga. 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 ewusebenzisa. Ubunzima beemveliso ezifutshane kunye nobude obungaguqukiyo akufanele budlule i-5% yomthamo opheleleyo wokuhanjiswa, kunye neetyhubhu zesikwere esixande ezinobunzima obungaphezu kwe-20kg / m, akufanele idlule i-10% yomthamo opheleleyo 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 i-tube rectangular
Iityhubhu ezixande zihlelwa ngokwenkqubo yemveliso: iityhubhu ezisikweri ezingenamthungo ezishushu eziqengqelekayo, iityhubhu zesikwere ezingenamthungo ezitsalwa ngokubanda, iityhubhu zesikwere ezingenamthungo, kunye netyhubhu edityanisiweyo yesikwere. Phakathi kwabo, umbhobho odityanisiweyo wesikwere wahlulwe: (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) ngokwe-weld-straight Seam welded square pipe, i-spiral welded square pipe.

2. Ukuhlelwa kwezinto eziphathekayo ityhubhu yoxande
Imibhobho yesikwere ihlelwa ngokwezinto zabo: iibhobho ze-carbon steel square kunye ne-low-alloy square pipes. Intsimbi yekhabhoni eqhelekileyo yahlulwe yaba: 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 eskweri enqamlezileyo, imibhobho yesikwere esixande (2) imibhobho yesikwere esixande esixande, imibhobho eskweri emile okwentyatyambo, imibhobho eskweri enemilo evulekileyo.

5. Ukuhlelwa konyango lomphezulu wombhobho wexande
Imibhobho yesikwere yahlulahlulwe ibe lunyango lomphezulu: idiphu eshushu-dip yesikwere imibhobho, imibhobho yesikwere ene-electro-galvanized, imibhobho yesikwere egqunywe ngeoyile, imibhobho yesikwere echotshiweyo.

6. Sebenzisa ukuhlelwa kombhobho wexande
Imibhobho yesikwere ihlelwa ngenjongo-isikwere imibhobho yokuhlobisa, imibhobho yesikwere yezixhobo zoomatshini, imibhobho yesikwere yoshishino loomatshini, imibhobho yesikwere yoshishino lweekhemikhali, imibhobho yesikwere yezakhiwo zentsimbi, imibhobho yesikwere yokwakhiwa kweenqanawa, imibhobho yesikwere yeenqwelo, imibhobho yesikwere kwiintsimbi zentsimbi kunye neentsika Ityhubhu, injongo ekhethekileyo ityhubhu yesikwere.

7. Ukuhlelwa kobunzima bodonga lwetyhubhu exande
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 sensimbi, ubunjineli bamandla, izityalo zamandla, oomatshini bezolimo kunye neekhemikhali, iindonga zamakhethini eglasi, i-chassis yemoto, izikhululo zeenqwelo moya, njl.
