Cov kav hluav taws xob xa mus rau cov khoom siv yeeb nkab siv rau kev tua hluav taws, txuas cov khoom siv tua hluav taws thiab cov khoom siv hluav taws xob, thiab thauj cov dej tua hluav taws, roj av lossis lwm yam xov xwm. Vim yog cov kev cai tshwj xeeb, cov tuab thiab cov khoom siv ntawm cov kav dej tua hluav taws muaj cov kev cai tshwj xeeb, thiab cov xim liab yog txau los thauj cov dej tua hluav taws.
Txij li thaum cov kav dej tiv thaiv hluav taws feem ntau nyob hauv lub xeev zoo li qub, cov kev cai rau cov kav dej kuj tseem nruj. Cov kav dej yuav tsum tau tiv taus siab, corrosion, thiab kub kub. Muaj tsib hom hluav taws kub ducts:
Cov kav dej ductile hlau
Tom qab ntxiv spheroidizing tus neeg sawv cev rau cov cam khwb cia hlau ntawm No. 18 thiab saum toj no, cov yeeb nkab yog nrum los ntawm high-speed centrifugal casting siv lub tshuab centrifugal ductile hlau. Nws yog hu ua "ductile hlau yeeb nkab", hu ua ductile hlau yeeb nkab lossis ductile hlau yeeb nkab. Xa mus rau cov yeeb nkab hlau thiab cov yeeb nkab hlau yeeb nkab.
cev tooj
Tube tooj liab kuj hu ua tooj liab raj. Ib yam ntawm cov yeeb nkab uas tsis yog-ferrous hlau, nws yog ib tug nias thiab kos seamless yeeb nkab. Cov yeeb nkab tooj liab muaj zog, corrosion-resistant zog tau ua rau nws yog ib qho kev xaiv nrov rau cov neeg cog lus niaj hnub los txhim kho cov kav dej, cua sov thiab cua txias hauv cov tsev nyob thiab cov tsev lag luam.
Alloy tube
Alloy yeeb nkab yog ib hom seamless steel yeeb nkab. Nws qhov kev ua tau zoo yog ntau dua li ntawm cov yeeb nkab seamless steel. Vim tias cov yeeb nkab steel no muaj ntau dua Cr, nws qhov kub thiab txias tsis kam, qhov kub tsis kam thiab corrosion kuj zoo dua li lwm cov kav dej seamless. cov kav dej. Yog li ntawd, cov kav hlau alloy yog dav siv hauv roj av, tshuaj, hluav taws xob, boiler, tub rog thiab lwm yam lag luam.
Cov yeeb nkab sib xyaw
Cov yeeb nkab sib xyaw yog cov yeeb nkab ua los ntawm ob lossis ntau cov khoom siv. Nws yog ua los ntawm cov kav hlau thiab yog ua los ntawm polyethylene, cross-linked polyethylene thiab lwm yam ntaub ntawv uas tsis yog xim hlau welded sab hauv thiab sab nraud. Nws muaj qhov zoo ntawm cov kav hlau thiab cov kav hlau tsis muaj hlau.
cov yeeb nkab yas
Raws li ib qho tseem ceeb ntawm cov khoom siv tshuaj hauv tsev, cov kav dej yas tau txais kev pom zoo los ntawm cov neeg siv rau lawv cov kev ua tau zoo, kev nyiam huv, kev tiv thaiv ib puag ncig, kev noj tsawg thiab lwm yam zoo. Lawv feem ntau suav nrog UPVC cov kav dej, UPVC cov kav dej, cov kav dej txhuas-yas, polyethylene (PE) ) cov kav dej no.
