Umbhobho wesikwere ligama lombhobho wesikwere kunye nombhobho wexande, oko kukuthi, umbhobho wentsimbi kunye nobude obulinganayo kunye nokungalingani. Yenziwe ngentsimbi yentsimbi eqengqelekayo emva konyango lwenkqubo. Ngokuqhelekileyo, insimbi yomgca ikhutshwe, ifakwe, igxininiswe kwaye ifakwe kwi-welded ukwenza umbhobho ojikelezayo, emva koko ifakwe kumbhobho wesikwere ukusuka kumbhobho ojikelezayo, kwaye emva koko inqunyulwe ubude obufunekayo.

1. Ukutenxa okuvumelekileyo kobukhulu bodonga lombhobho osisikwere akusayi kudlula kudityaniswe okanye thabatha i-10% yobukhulu bodonga xa ungqimba lungekho ngaphezu kwe-10mm, dibanisa okanye thabatha i-8% yobukhulu bodonga xa ubukhulu bodonga bungaphezulu. ngaphezu kwe-10mm, ngaphandle kobunzima bodonga lweekona kunye neendawo zokuwelda.

2. Ubude obuqhelekileyo bokuhanjiswa kombhobho we-square rectangular yi-4000mm-12000mm, ubukhulu becala 6000mm kunye ne-12000mm. I-tube ye-rectangular ivumelekile ukuhambisa imveliso emfutshane kunye nobude obungaguqukiyo obungekho ngaphantsi kwe-2000mm, kwaye ingahanjiswa ngendlela ye-tube interface, kodwa i-Demander iya kunqumla ityhubhu yokujongana nayo xa iyisebenzisa. Ubunzima begeyiji emfutshane kunye neemveliso zegeyiji ezingaguqukiyo aziyi kuba ngaphezu kwe-5% yomthamo opheleleyo wokuhanjiswa. Kwiityhubhu zomzuzu wesikweri ezinobunzima obungaphezulu kwe-20kg / m, ayisayi kudlula i-10% yomthamo opheleleyo wokuhanjiswa.

3. Iqondo lokugoba lombhobho we-square rectangular aliyi kuba likhulu kune-2mm ngemitha nganye, kwaye idigri yokugoba iyonke ayiyi kuba nkulu kune-0.2% yobude obupheleleyo.

Ngokwenkqubo yemveliso, iityhubhu zesikwere zahlulwe zaba ziityhubhu zesikwere ezingenamthungo ezishushu-eziqengqelekayo, iityhubhu zesikwere ezipholileyo ezitsalwa ngokubanda, iityhubhu zesikwere ezingenamthungo kunye netyhubhu edityanisiweyo yesikwere.

Umbhobho wesquare odibeneyo uhlukaniswe

1. Ngokwenkqubo - i-arc welding square tube, ukumelana ne-welding square tube (i-frequency ephezulu kunye ne-frequency ephantsi), i-gas welding square tube kunye ne-furnace welding square tube.

2. Ngokwe-weld - i-welded square pipe kunye ne-spiral welded square pipe.

Ukuhlelwa kwezinto

Iityhubhu zesikwere zohlulwe zibe ziityhubhu zesikwere zentsimbi eziqhelekileyo kunye neetyhubhu zesikwere sealloy ephantsi ngokwezinto eziphathekayo.

1. Intsimbi ye-carbon eqhelekileyo yahlulwe kwi-Q195, Q215, Q235, SS400, 20 # intsimbi, i-45 # intsimbi, njl.

2. Insimbi ye-alloy ephantsi ihlukaniswe kwi-Q345, 16Mn, Q390, St52-3, njl.

Ukuhlelwa komgangatho wemveliso

ityhubhu yesikwere yahlulwe yaba ityhubhu yeskweri esemgangathweni yesizwe, ityhubhu yesikweri esemgangathweni yaseJapan, ityhubhu yaseBritani enesikweri esiqhelekileyo, ityhubhu yesikweri esiqhelekileyo saseMelika, ityhubhu yesikwere esiqhelekileyo saseYurophu kunye netyhubhu yesikwere esingeyosiqhelo ngokwemigangatho yemveliso.

Ukuhlelwa kwemilo yecandelo

Imibhobho yesikwere ihlelwa ngokwemilo yecandelo:

1. I-tube yesikwere yecandelo elilula: ityhubhu yesikwere, i-rectangular tube.

2. Ityhubhu yesikwere enecandelo elintsonkothileyo: ityhubhu yesikwere emile okwentyatyambo, ityhubhu yesikwere evulekileyo, ityhubhu yesikwere enethati kunye netyhubhu yesikwere enemilo ekhethekileyo.

Ukuhlelwa konyango olungaphezulu

Imibhobho yesikwere yahlulwe yaba yimibhobho yesikwere eshushu-diphu, imibhobho yesikwere enezikwere ze-electro galvanized square, imibhobho yesikwere eneoyile kunye nemibhobho yesikwere echoliweyo ngokonyango lomphezulu.

Sebenzisa ulwahlulo

Iityhubhu zesikwere zihlelwa ngokusetyenziswa: iityhubhu zesikwere zohombiso, iityhubhu zesikwere zesixhobo somatshini, iityhubhu zesikwere kushishino lomatshini, iityhubhu zesikwere kushishino lweekhemikhali, iityhubhu zesikwere sokwakhiwa kwentsimbi, iityhubhu zesikwere sokwakha inqanawa, iityhubhu zesikwere semoto, iityhubhu zesikwere iintsimbi zentsimbi kunye neentsika, kunye neetyhubhu zesikwere ngeenjongo ezikhethekileyo.

Ulwahlulo lokutyeba kweendonga

Iityhubhu ezibuxande zihlelwa ngokobunzima bodonga: iityhubhu ezishinyeneyo ezityebileyo eziluxande, iityhubhu ezishinyeneyo ezinongxande kunye neetyhubhu ezinodonga olucekethekileyo. Umzi-mveliso wethu unobuchwephesha bemveliso kwimarike, kwaye unobuchule kakhulu. Wamkelekile abahlobo bamazwe ngamazwe ukuba bathethe. Siza kuzama konke okusemandleni ethu ukuhlangabezana neemfuno zakho ezahlukeneyo.
