ASTM A53 Hlau Yeeb Nkab Hom thiab Qib
Rau ASTM A53 muaj ERW thiab Hom F, E, S seamless steel kav npog Qib A thiab B.
A53 Hom F, Rauv Butt Weld, Qib A Nruam Weld
A53 Hom E, Hluav taws xob tiv thaiv vuam (ERW), qib A thiab qib B.
A53 Hom S, seamless steel yeeb nkab, hauv Qib A thiab Qib B.
Nyob rau hauv cov ntaub ntawv ntawm ASTM A53 Qib B ntawm ERW (Electric Resistance Welded) yeeb nkab, vuam seam yuav tsum tau kho cua sov kom tsawg kawg yog 540 ° C [1000 ° F]. Nyob rau hauv no txoj kev, tsis muaj untempered martensite.
Nyob rau hauv rooj plaub ASTM A53 B yeeb nkab yog txias nthuav, ces qhov nthuav yuav tsum tsis txhob ntau tshaj 1.5% ntawm qhov yuav tsum tau sab nraud txoj kab uas hla.
Nco ntsoov tias Hom F tsis yog siv rau cov hlaws dai, thiab yog tias Hom S lossis Hom E tau thov rau cov hlaws lossis txias dabtsi yog khoov, nws raug nquahu kom siv ASTM A106 Qib A yeeb nkab.) Txawm li cas los xij, kev siv ASTM A106 Qib B rau kev khoov txias thiab dov tsis raug txwv. Nyob ntawm cov chaw tsim khoom tsim, ASTM A53 Hom E steel yeeb nkab tuaj yeem ua rau tsis txias-ntws lossis txias-ntws.

ASTM A53 Yeeb Nkab Daim Ntawv Thov
1. Kev tsim kho, kev thauj mus los hauv av, kev tshem tawm dej hauv av thaum tsim kho, kev thauj mus los hauv dej, thiab lwm yam.
2. Bearing poob lawm, machining ntawm machinery qhov chaw.
3. Daim ntawv thov hluav taws xob: kev xa hluav taws xob, kev ua kua dej rau lub zog hluav taws xob hydraulic.
4. Antistatic raj rau cua fais fab nroj tsuag, thiab lwm yam.
5. Cov kav dej yuav tsum muaj zinc txheej.
Standard packing:
Peb tuaj yeem muab cov packing packing, hauv cov khoom ntim, ntim lub thawv, tiv thaiv ntoo ntawm ob sab ntawm cov kav dej thiab tsim kom muaj kev tiv thaiv zoo rau kev xa khoom hiav txwv. Raws li cov neeg siv khoom xav tau.
