Cov kav dej thauj mus los yog cov yeeb nkab uas muaj qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Nws yog siv los thauj cov kua dej xws li dej, roj, thiab roj.
Seamless kav dej rau kev thauj mus los muaj cov hollow seem thiab tau dav siv los ua cov kav dej thauj cov kua dej, cov kav dej thauj cov roj, cov nkev roj, cov roj nkev, dej thiab qee cov khoom siv, thiab lwm yam. Piv nrog cov khoom siv hlau xws li cov hlau puag ncig, thaum khoov thiab torsional lub zog yog tib yam, cov kav dej thauj mus los yog sib dua hauv qhov hnyav. Nws yog ib qho kev lag luam hla ntu hlau thiab tau siv dav hauv kev tsim cov khoom siv thiab cov khoom siv tshuab, xws li cov kav dej tho roj thiab cov tsheb sib kis. Axles, tsheb kauj vab racks thiab steel scaffolding siv nyob rau hauv kev tsim kho vaj tse, thiab lwm yam.

Mechanical cwj pwm
Seamless Steel Yeeb Nkab rau kev thauj mus los
ntev
1. Kub dov (extruded, expanded) steel yeeb nkab yog 3-12m 2. Cold drawn (dov) steel yeeb nkab yog 3-10.5m
Curvature 1. When the wall thickness is ≤15mm, it shall not be greater than 1.5mm/m. 2. When the wall thickness is >15mm, nws yuav tsum tsis txhob siab tshaj 2. 0mm/m. 3. Thaum txoj kab uas hla sab nraud loj dua lossis sib npaug li 351mm, nws yuav tsum tsis txhob siab dua 3.0mm/m.
(Ob txoj kab uas hla-phab ntsa thickness) * phab ntsa thickness * 0 02466=kg / meter (hnyav ib 'meter')
Cov kev cai kav dej rau kev thauj mus los
Rau welded kav nrog API thiab lwm yam yuav tsum tau, ultrasonic flaw detection thiab hydraulic siab kuaj kuj yuav tsum tau rau cov welds ntawm txhua welded yeeb nkab;
Rau kev thauj cov tshuaj corrosive, tag nrho cov kav hlau yuav tsum tau kho los tiv thaiv corrosion ntawm phab ntsa sab hauv.
Cov kav dej yuav tsum muaj cov burrs sab hauv tshem tawm kom txo tau cov dej xa tawm.
Nrog rau kev tsim tawm txhua xyoo ntawm 10 lab tons, gnee yog cov chaw tsim khoom loj tshaj plaws ntawm ERW square kav, cov kav dej, cov kav dej hollow, cov kav dej galvanized thiab kauv welded kav. Kev muag khoom txhua xyoo ncav cuag US $ 5 nphom. Nws muaj 59 dub ncaj seam welded yeeb nkab ntau lawm kab, 10 galvanized yeeb nkab ntau lawm kab, 3 kauv welded yeeb nkab ntau lawm kab, thiab 1 JCOE LSAW steel yeeb nkab ntau lawm kab.
