TxogASTM A234 WPB yeeb nkab fittings
ASTM A234 yog Standard Specification rau steel yeeb nkab fittings xws li carbon thiab alloy steel khoom rau nruab nrab thiab kub kev pab cuam.Nws npog steel fittings ntawm seamless thiab welded hom.Steel Pipe fittings yog siv nyob rau hauv siab pipelines thiab nyob rau hauv siab nkoj fabrications.Cov khoom siv fittings no muaj cov hlau tua, forgings, tuav, daim hlau, seamless los yog HFW (fusion welded) yeeb nkab khoom, nrog rau cov hlau muab tub lim ntxiv.
WPB yog dab tsi?
W = WELDABLE / wrought
P = RELATED RAU P NUMBER OF ALLOY MATERIAL
B = REFEER TO MINIMUM YIELD NTAWM MATERIAL
Lawv muaj nyob rau hauv kev kho tshiab ntawm ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, thiab MSS-SP-97.Tsis tas li ntawd dav siv nyob rau hauv siab piping thiab nyob rau hauv siab hlab ntsha fabrication rau kev pab nyob rau hauv nruab nrab thiab siab kub.Cov qib yog ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 thiab WP22.

Qhov txawv ntawm A105 thiab A234
ASTM A234 WPB Yeeb Nkab Fittings yog tsim los ntawm wrought carbon steel uas lawv muaj zog heev thiab tuaj yeem siv rau hauv cov kev xav tau siab.ASTM A234 WPB raug kho kom sov thiab tom qab ntawd tso cai kom txias sai.
Carbon Steel Forged Fittings yog cov yeeb nkab fittings ua los ntawm A105 Khoom.Cov no yog tsim nyob rau hauv annealed, normalized, normalized thiab tempered los yog quenched thiab tempered tej yam kev mob.
