Cov kav hlau tsis muaj qhov txuas tuaj yeem muab faib ua ASTM American tus qauv seamless steel kav, DIN German tus qauv seamless steel kav, JIS Japanese tus qauv seamless steel kav, GB lub teb chaws seamless steel kav, API seamless steel kav thiab lwm hom raws li lawv cov qauv. ASTM American tus qauv seamless steel kav yog nyob rau hauv Nws yog qhov sib xws thoob ntiaj teb thiab muaj ntau hom thiab ceg.
Tam sim no cov kev cai tseem ceeb ntawm ASTM seamless steel yeeb nkab ASTM stm a210 / a210m / astm sa210 / sa-210s American standard seamless steel yeeb nkab tau teev raws li hauv qab no:ASTM A210/A210M/ASME SA-210/SA-210M Lub Hom Phiaj: tsim nyog rau cov raj boiler thiab cov boilers Cov kav dej Flue, suav nrog cov qhov kawg kev nyab xeeb, cov qhov rooj thiab cov kav dej txhawb nqa, thiab cov kav dej hlau nruab nrab uas tsis muaj qhov tuab tsawg kawg nkaus rau cov kav dej superheater. Feem ntau tsim cov yeeb nkab hlau qib: A-1, C, thiab lwm yam. Tom qab kev sib tham, lwm cov yeeb nkab hlau kuj tuaj yeem muab tau.
Cov txheej txheem tsim cov yeeb nkab hlau tsis muaj seamless:
Cov kav hlau tsis muaj seamless raug muab faib ua cov kav hlau kub dov seamless, cov kav hlau txias kos seamless, thiab lwm yam raws li lawv cov txheej txheem tsim khoom. Lub cheeb ntawm cov kav hlau tsis muaj seamless feem ntau yog 406mm-1800mm, thiab phab ntsa tuab yog 20mm-220mm. Raws li lawv siv, lawv tuaj yeem muab faib uacov kav hlau tsis muaj seamless rau cov qauv, cov kav hlau tsis muaj seamless rau cov kua dej, cov yeeb nkab hlau tsis muaj seamless rau cov boilers, thiabcov kav hlau tsis muaj seamless rau cov kav dej roj.
