Square chubhuimhando yehollow square chikamu chimiro chesimbi chubhu, inozivikanwawo sesquare chubhu,rectangular chubhu.Tsanangudzo yaro inoratidzwa mu mm yekunze dhayamita * madziro ukobvu.Iyo inogadzirwa neinopisa yakakungurutswa simbi tambo nekutonhora kukunguruka kana kutonhora kudhirowa.
Kushandiswa kweseamless square pipe:
Seamless square uyeyuantai rectangular chubhudzinoshandiswa zvakanyanya.Inowanzo shandiswa kugadzira zvimiro zvemukati uye memechani zvikamu, senge pombi yekuchera oiri, mota yekufambisa shaft, bhasikoro furemu uye simbi scaffolding inoshandiswa mukuvaka, iyo inogadzirwa nemhando yepamusoro kabhoni structural simbi nekupisa kana kutonhora kudhirowa. inonyanya kushandiswa semapombi kana zvikamu zvakaumbwa kutakura zvinwiwa.
Mhando ye seamless rectangular chubhu:
1. Zvinoenderana nenyaya, inogona kukamurwa kuita yakajairwa kabhoni chimiro simbi uye yakaderera alloy yakakwira simba rekuvaka simbi.Iyo kabhoni yemukati yekare haingapfuuri 4.5%;sarufa ≤ 0.035;phosphorus ≤ 0.005;chromium ≤ 0.15;nickel content <0.25;mhangura ≤ 0.30;Iyo yekupedzisira ine shoma shoma yesilicon, manganese uye vanadium kuwedzera kune kabhoni, sarufa, phosphorus uye chromium.
2. Zvinoenderana nemhando yepamusoro:
(1) Pedzisa:
1 Nzvimbo dzemukati nekunze dzeiyo seamless square chubhu ichave yakatsetseka uye yakati sandarara isina mabubbles nemakwinya.
2 Kana nzvimbo yemukati iri pasi pe 100 mm2, iyo inobvumirwa kushivirira kwenzvimbo yemukati ndeye ± 0.2 mm.
3 Kana iyo nzvimbo yemukati yakakura kupfuura 100 mm2, iyo inobvumirwa kushivirira kwenzvimbo yemukati ndeye ± 0.5 mm.
4 Hapana kutsemuka kana kupeta zvinotenderwa mukati memukati;5 Hapazovi nevanga 6 Hapana mavanga akajeka uye mavanga.
(2) Flatness:
1 Nzvimbo dzemukati nekunze dzemachubhu asina musono anofanirwa kunge akati sandarara uye akatsetseka.
2 Hapafanirwe kuve nekusaenzana kuri pachena kana ichionekwa negirazi rinokudza 10X.
3 Chiso chekupedzisira chemuromo chinoenderana nechepakati pepombi.
4 Nechekunoperera pamuromo wepombi panofanira kuva pasina mabura.
5 Hapafaniri kuunyana panokona pombi;
6 Migumo yose yenyere inofanira kufanana;
7 Hapana bundu riri pachena rinotenderwa pakupisa kana ngura yabviswa.
8 Hapafaniri kuva nemakomba ari pachena.
9 Hapana kukanganisa kunokanganisa kushandiswa kunobvumidzwa.
10 Kana muchina wekukungurusa ndiro uchishandiswa kupinza, fillet radius paweld haizove shoma pane ukobvu hwesimbi yepasi.
(3) Kurongeka kwedimensional:
1 Iko kukanganisa kwekutenderera hakufaniri kudarika kutsauka kwakanyanya kunotsanangurwa muyero inoenderana neinopfuura 2 mm/m2.
2 Kutwasanuka uye kutsauka kwekona hakufanire kudarika 1/20 yekutsauka kwakanyanya kunotsanangurwa muyero inoenderana.
3 Muganho wekutsauka kwehurefu hauzove wakakura kupfuura 1.5 nguva dzeiyo inoenderana kukosha kwakatarwa.
The quality control ofyuantai simbi pombiyakasimba kwazvo, saka vatengi vanogona kusarudza nechivimbo.Yuantai kambaniYakawana 77 patents,Yuantai simbiakahwina shasha imwe chete yerectangular chubhu indasitiri kwemakore gumi akateedzana,
Kana iwe uchida kuwanayuantai simbi pombi mutengo，Ndapota taura nesu.
