Square tubyog ib hom hollow square seem zoo li steel raj, tseem hu ua square raj,lub cev. Nws specification yog qhia nyob rau hauv mm ntawm txheej kab * phab ntsa thickness. Nws yog ua los ntawm kub dov steel sawb los ntawm txias dov los yog txias kos duab.
Kev siv seamless square yeeb nkab:
Seamless square thiabyuantai lub rajyog siv dav. Nws yog feem ntau siv los tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li roj laum yeeb nkab, tsheb sib kis ncej, tsheb kauj vab ncej thiab steel scaffolding siv nyob rau hauv kev tsim kho, uas yog ua los ntawm high-zoo carbon structural steel los ntawm kub dov los yog txias daim duab, thiab yog feem ntau yog siv los ua cov kav dej lossis cov khoom siv los thauj cov kua dej.
Hom Seamless Rectangular Tube:
1. Raws li cov khoom siv, nws tuaj yeem muab faib ua cov pa roj carbon zoo tib yam steel thiab tsis tshua muaj hlau alloy siab zog steel qauv. Cov ntsiab lus carbon ntawm qhov qub yuav tsum tsis pub tshaj 4.5%; sulfur ≤ 0.035; phosphorus ≤ 0.005; chromium ≤ 0.15; nickel cov ntsiab lus <0.25; tooj liab ≤ 0.30; Cov tom kawg muaj ib qho me me ntawm silicon, manganese thiab vanadium ntxiv rau carbon, sulfur, phosphorus thiab chromium.
2. Raws li qhov chaw zoo:
(1) Ua tiav:
1 Qhov chaw sab hauv thiab sab nraud ntawm seamless square raj yuav tsum du thiab tiaj yam tsis muaj npuas thiab wrinkles.
2 Thaum lub cheeb tsam sab hauv yog tsawg dua 100 mm2, qhov kam rau siab ntawm qhov chaw sab hauv yog ± 0.2 hli.
3 Thaum lub cheeb tsam sab hauv yog ntau dua 100 mm2, qhov tso cai kam rau ntawm qhov chaw sab hauv yog ± 0.5 hli.
4 Tsis muaj kab nrib pleb lossis folds raug tso cai rau ntawm sab hauv; 5 Yuav tsum tsis muaj caws pliav 6 Tsis muaj qhov kos thiab qhov nqaij tawv.
(2) Flatness:
1 Sab hauv thiab sab nraud ntawm seamless square raj yuav tsum tiaj tus thiab du.
2 Yuav tsum tsis muaj qhov tsis sib xws thaum pom nrog 10X magnifying iav.
3 Lub ntsej muag kawg ntawm lub nozzle yog perpendicular mus rau qhov nruab nrab ntawm cov yeeb nkab.
4 Lub ntsej muag kawg ntawm cov yeeb nkab orifice yuav tsum tsis muaj burrs.
5 Yuav tsum tsis txhob muaj qhov txhab ntawm qhov khoov ntawm cov yeeb nkab.
6 Ob qhov kawg ntawm cov yeeb nkab yuav tsum sib npaug.
7 Tsis pub muaj qhov pom tseeb ntawm qhov vuam tom qab tshem tawm xeb.
8 Yuav tsum tsis txhob muaj qhov pom tseeb.
9 Tsis muaj qhov cuam tshuam rau kev siv tau tso cai.
10 Thaum lub phaj dov tshuab yog siv rau vuam, lub vojvoog fillet ntawm qhov vuam yuav tsum tsis txhob tsawg dua qhov tuab ntawm lub hauv paus hlau.
(3) Dimensional raug:
1 Qhov yuam kev roundness yuav tsum tsis pub tshaj qhov siab tshaj qhov sib txawv uas tau teev tseg hauv cov qauv sib xws los ntawm ntau dua 2 mm / m2.
2 Qhov ncaj thiab qhov sib txawv ntawm lub kaum sab xis yuav tsum tsis pub tshaj 1/20 ntawm qhov sib txawv siab tshaj plaws uas tau teev tseg hauv cov qauv sib xws.
3 Qhov kev txwv qhov sib txawv ntawm qhov ntev yuav tsum tsis txhob ntau tshaj 1.5 npaug ntawm tus nqi sib thooj.
