BabaganFitting pipa ASTM A234 WPB
ASTM A234 minangka Spesifikasi Standar kanggo fitting pipa baja kalebu karbon lan bahan baja campuran kanggo layanan suhu moderat lan dhuwur.Isine fitting baja saka jinis rapi lan gandheng.Fitting Pipa Baja ditrapake ing pipa tekanan lan ing fabrikasi prau tekanan.Bahan fitting kasebut kalebu baja sing dibunuh, tempa, bar, piring, produk pipa sing mulus utawa HFW (fusi las), kanthi logam pengisi ditambah.
Apa WPB?
W = WELDABLE / tempa
P = RELATED TO P NOMOR MATERIAL ALLOY
B = RUJUKAN MINIMUM PENGELUARAN MATERI
Padha kasedhiya ing revisi paling anyar saka ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, lan MSS-SP-97.Uga digunakake digunakake ing pipa tekanan lan ing fabrikasi prau tekanan kanggo layanan ing suhu moderat lan dhuwur.Gelar kasebut yaiku ASTM A234 WPB, WPC, WP5, WP9, WP91, WP11, WP12 lan WP22.

Bedane antarane A105 lan A234
ASTM A234 WPB Pipe Fittings digawe saka baja karbon tempa sing kuwat banget lan bisa ditrapake ing syarat kekuatan dhuwur.ASTM A234 WPB diolah kanthi panas banjur diidini adhem kanthi cepet.
Carbon Steel Forged Fittings yaiku fitting pipa sing digawe saka Bahan A105.Iki diprodhuksi ing kondisi anil, normal, normal lan tempered utawa quenched lan tempered.
