Yuav luag txhua tus paub tias cov kav hlau zoo li cas. Feem ntau lawv muaj ib seem ntawm ntau yam diameters. Cov kav dej profiled yog tsim nrog ib ntu hauv daim ntawv ntawm oval, duab plaub, square, polygon.
cov ntaub ntawv dav dav
Cov yam ntxwv ntawm cov hlau dov no yuav tsum ua raws li GOST 13663-86. Tam sim no, cov kav dej profiled ntawm 120 tus qauv loj tuaj yeem pom ntawm muag. Lub assortment ntawm cov khoom siv hluav taws xob welded sib haum raws li lub xeev cov qauv hauv qab no: oval - 8642-68; square - 8639-82; ib-8645-68. Rau kev tsim cov kav dej, cov hlau ntawm cov qib hauv qab no feem ntau yog siv: St2ps, St2sp, St2kp, St4ps, St4sp, St4kp (GOST380-94); 10, 20, 35, 45, 10PS, 08 KP (GOST 1050-88). Profiled kav kuj tuaj yeem ua los ntawm cov hlau tsis tshua muaj hlau 09G2S. Cov khoom lag luam stainless hlau txawv ntawm cov khoom zoo tib yam tsis yog nyob rau hauv ntu ntu, tab sis kuj nyob rau hauv phab ntsa thickness.
Kev faib tawm ntawm cov kav dej profiled
Raws li lub hom phiaj ntawm cov khoom siv hlau no, cov yeeb nkab hauv qab no tau muab faib:
- A - rau nws normalizedmechanical zog.
- B - txhua yam thiab tshuaj lom neeg muaj zog rau nws.
Cov kav dej Profiled tuaj yeem ua tau ob txoj hauv kev: nrog thiab tsis muaj kev kho cua sov. Raws li txoj kev tsim khoom, lawv tau muab faib ua ob peb pawg: txias-tsim (muaj cov qauv kev ua haujlwm siab), kub-tsim, hluav taws xob-welded, txias-tsim hluav taws xob-welded kav ua los ntawm carbon steel (kub, tab sis kim dua).
Cov kav dej profile muaj lub zog siv tshuab ntau dua li cov kav dej ib puag ncig. Nyob rau tib lub sijhawm, qhov hnyav ntawm cov khoom zoo li no nrog cov yam ntxwv zoo sib xws yuav yog kwv yees li 20% tsawg dua. Xws li cov kav dej yog welded thiab seamless. Cov qub yog ua los ntawm sawb los yog cov ntawv hlau, thaum lub tom kawg yog ua los ntawm tubular blanks thiab khoom hlau ingots.
Cov kav dej Profiled yooj yim dua rau nruab, uas tso cai rau lawv siv rau ntau qhov chaw ntawm kev lag luam. Lawv yog cov universal dov hlau, vim lawv muaj cov khoom nram qab no: siab manufacturability, kev ntseeg tau thiab yooj yim ntawm nodal kev twb kev txuas, tsawg kawg nkaus welds, tsawg aerodynamic kuj. Cov qauv tsim los ntawm xws li hlau-yob txo lub peev xwm ntawm lub hauv paus, tus nqi ntawm nws cov installation thiab ua rau nws muaj peev xwm tsim tau zoo heev ruaj hlau-pob zeb lug. Ua tsaug rau kev siv cov kav dej profiled, qhov nrawm ntawm kev teeb tsa ntawm cov qauv thiab cov tsev nce ntxiv.
Scope of profiled pipes
hom dov hlau no yog siv rau hauv kev tsim kho, kev tsim kho tshuab, kev tsim kho ntawm ntau yam thav duab (rau kev txhawb nqa, spans thiab ceilings). Feem ntau, oval dov cov khoom siv rau cov khoom siv kho kom zoo nkauj thiab hauv kev tsim cov rooj tog. Rectangular thiab square kav yog tsim nyog rau cov qauv tso rau ntawm qhov chaw tiaj tus. Tam sim no nws tau dhau los ua fashionable siv cov kav dej profiled rau lub laj kab. Rau nws cov khoom siv, ncej ntawm 60x60 mm yog haum. Lub sijhawm nruab nrab ntawm lawv yog 3 m. Qhov tob yog 1.2 m. Thaum tsim lub laj kab, siv cov yeeb nkab profiled 20, 40x25 mm. Tag nrho cov seem yog tsim los ntawm nws, welded rau ncej.
