ASTM A53 tus qauv yog ib qho ntawm feem ntau siv cov pa roj carbon steel yeeb nkab cov qauv hauv cov roj & roj, cov qauv, kev tsim kho, cov kav dej tsis tshua muaj siab, conveyor rollers, thiab lwm yam txheej txheem.
ASTM A53 yog ib qho ntawm cov qauv ntawm American Society for Testing and Materials. Qhov luaj li cas rau cov kav dej yog los ntawm NPS 1/8 "mus rau NPS 26". Cov phab ntsa tuab ntawm cov kav dej kuj tau hais nyob rau hauv tus qauv -astm a53 yeeb nkab Schedule 10, astm a53 yeeb nkab Teem caij 20, astm a53 yeeb nkab Teem caij 30, astm a53 yeeb nkab Teem caij 40, astm a53 yeeb nkab Teem caij 60, thiab astm a53 yeeb nkab Teem caij 80. Ntau hom kev ua tiav muaj rau ASTM A53 cov kav dej yog xim dub thiab kub-dipped, zinc-coated, welded, thiab seamless.
ASTM A53 Qib A
ASTM A53 Qib A yeeb nkab (tseem hu ua ASME SA53 yeeb nkab) yog npaj rau kev siv tshuab thiab siab. Nws yog tsim rau welding thiab shaping hauj lwm zoo li coiling, dabtsi yog khoov, thiab flanging nyob rau hauv tej yam tshwm sim.
ASTM A53 Qib B
ASTM A53 Qib B yeeb nkab (tseem hu ua ASME SA53 yeeb nkab). ASTM A53 Qib B yeeb nkab tsim nyog rau vuam thiab npog Seamless thiab Welded, Dub thiab Kub-Dipped Galvanized nominal (nruab nrab) phab ntsa yeeb nkab rau coiling, dabtsi yog khoov, flanging, thiab lwm yam. cov haujlwm tshwj xeeb.
ASTM A53 Qib B vs Qib A
1. Tshuaj muaj pes tsawg leeg: qhov sib txawv tseem ceeb ntawm ob qib ntawm cov hlau hauv cov ntsiab lus carbon thiab manganese. astm a53 qib ib qib carbon thiab manganese cov ntsiab lus kuj tsawg, yog li qib ib qib ntawm cov yeeb nkab steel weldability thiab ductility zoo heev, tab sis qib b ntawm carbon thiab manganese cov ntsiab lus siab, lub zog thiab hardness yuav zoo dua. Koj tuaj yeem pom cov lus hauv qab no
Tensile zog: 415 MPa (60 ksi) thiab siab dua VS 330 MPa (48 ksi) thiab siab dua
Yield zog: 240 MPa (35 ksi) thiab siab dua VS 205 MPa (30 ksi) thiab siab dua
Elongation: 25% ntawm 2- nti nplai VS 30% (hauv 2- nti nplai)
2. Daim Ntawv Thov: Qib A: Feem ntau yog siv rau cov ntawv thov nyob rau hauv qis qis thiab qis kub, xws li cov kav dej, cov kav dej, cov khoom siv hauv tsev, thiab lwm yam.
Qib B: Haum rau kev siv nyob rau hauv nruab nrab siab thiab kub tej yam kev mob, xws li roj, natural gas, chav, dej thauj.
ASTM A53 HOM e, f, s yeeb nkab specification
- ASTM A53 Hom F - Rauv taub qab welded nruam Welded yeeb nkab
ASTM A53 Hom F Qib A yeeb nkab yog tsim los ntawm kev sib txuas txuas txuas ntxiv, thiab qhov txuas txuas ntev yog welded los ntawm forge welding. Cov txheej txheem ntawm cov chais yog ua haujlwm nyob rau hauv cov txheej txheem no los siv cov cuab yeej siv siab rau cov cua sov kawg ntawm lub kauj.
ASTM A53 Hom E - Hluav Taws Xob Hluav Taws Xob Welded Yeeb Nkab.
ASTM A53 Hom E Garde A thiab ASTM A53 Garde B cov kav dej yog tsim los ntawm cov kav hlau txuas txuas ntxiv, thiab cov kab txuas txuas ntev yog welded los ntawm cov cua sov uas tsim los ntawm hluav taws xob tiv thaiv ntawm cov yeeb nkab tsis sib haum. Ib txheej ntawm rollers kuj tau ua haujlwm nyob rau hauv qhov kev ua haujlwm no los sib sau ua ke rhuab kawg. Tom qab vuam, lub vuam seam ntawm Qib cov kav dej yog kho cua sov kom tsawg kawg yog 540 degree.
ASTM A53 Hom S - Seamless Yeeb Nkab
Cov txheej txheem extrusion yog siv los tsim ASTM A53 Hom S kav.
Cov hlau nyoos uas xav tau los ua cov kav dej yog tsim los siv lub qhov cub qhib, lub qhov cub hluav taws xob, lossis cov txheej txheem pa oxygen.
