A/SA106 yeeb nkab specifications
ASTM A106 thiab ASME SA106seamless siab yeeb nkab feem ntau yog siv rau hauv kev tsim cov roj thiab roj refineries, fais fab nroj tsuag, petrochemical nroj tsuag, boilers, thiab ships qhov twg cov kav dej yuav tsum tau thauj cov kua thiab gases uas muaj ntau dua kub thiab siab.
Cov khoom lag luam muaj ntau yam ntawm A / SA106 yeeb nkab hauv:
Qib B thiab C
NPS ¼" to 36" OD
Teem caij 20 txog XXH
Phab ntsa Thickness mus txog 5.500 "Thick
Scope
ASTM A106 thiab ASME SA106 npog seamless carbon steel nominal phab ntsa yeeb nkab rau siab -kev pab kub. Haum rau kev khoov, flanging thiab zoo sib xws ua haujlwm.
NPS 1-1/2 ″ thiab qis dua tuaj yeem yog kub tiav lossis txias kos. NPS 2 ″ thiab loj dua yuav tsum kub tiav tshwj tsis yog tias tau teev tseg.

Txheej txheem
Cov hlau raug tua, nrog cov txheej txheem melting tseem ceeb tau qhib -hearth, yooj yim- pa oxygen, lossis hluav taws xob- cub, tejzaum nws ua ke nrog cais degassing lossis refining.
Steel cam khwb cia nyob rau hauv ingots los yog strand cam khwb cia yog permissible.
Kub- cov yeeb nkab tiav tsis tas yuav tsum tau kho cua sov.
Txias- cov yeeb nkab kos yuav tsum tau kho kom sov tom qab qhov kawg ntawm qhov kawg rub dhau.
