** 1. Dab tsi yog qhov tuab ntawm A106 gr? **
* ASTM A106 GR. B cov yeeb nkab tsis muaj ib qho tuab ib qho tuab. Lub phab ntsa tuab yog nyob ntawm cov yeeb nkab ntawm cov yeeb nkab nominal loj (nps) thiab sijhawm (piv txwv li cov School 40, SchE 160). Koj yuav tsum xa mus rau cov qauv nyob sab hauv zoo li ASME B36.10M (rau NPS 1) lossis ASME B36.19m (rau qhov loj me) kom pom cov qhov loj me me) kom pom qhov loj me me rau muab cov yeeb nkab tuab thiab cov yeeb nkab. Cov sijhawm ib txwm muaj los ntawm SCH 40 (qauv) rau SCH 160 (hnyav hnyav).
** 2. Dab tsi yog ASTM A53 steel sib npaug rau? **
* Astm A53 Qib B yog ** Feem ntau cov khoom siv tau sib hloov tau ** rau ntau qhov kev siv ua ke nrog **} Cov yeeb nkab A106 1} Txawm li cas los xij, tsis muaj * kiag * sib npaug specification. A53 Gr kuj tseem ceeb heev nyob rau hauv cov neeg tawm tswv yim / tensile lub zog rau ** API 5L Qib B ** Kab 5.
** 3. Dab tsi yog qhov sib txawv ntawm A53 thiab A106 yeeb nkab? **
* ** Kev tsim: ** A53 tuaj yeem yog seamless (hom s) lossis hluav taws xob tiv thaiv welded (ERW, hom e lossis f). A106 tsuas yog seamless (sms).
* **Temperature Service:** A106 is specifically designed for **high-temperature service** (up to 750℃F / 400℃). A53 yog npaj rau ** qis dua kub ** iPhone thiab cov ntawv thov siab siab.
* ** KEV SIV SIV: ** A53 tau siv dav rau cov kav dej uas dav dav, qis {}}} cov kab siab, huab cua, thiab dej kab. A106 yog nyiam rau cov nroj tsuag hluav taws xob, ua kom zoo dua thiab cov kav dej piping nrog cov ntsuas kub ntau dua thiab ntsuas.
** 4. Dab tsi yog API 5l Qib X60 sib npaug rau ASTM? **
* Muaj ** tsis muaj cov yeeb nkab tiv thaiv kab mob ncaj qha ** rau API 5L X60. X60 txhais lus tsawg kawg yog los lub zog muaj zog ntawm 60,000 psi (414 mpa). ASTM cov yeeb nkab xaim qib (zoo li A53 / A106 / A333) tsis yog muaj kev txwv los ntawm kev cog lus lub zog hauv tib txoj kev. Qhov ze tshaj plaws lub zog yuav pom nyob rau hauv ** ttm A333 qib 6 ** (siab li cov khoom siv hluav taws xob nrog cov tshuaj sib txawv, kuaj, thiab kev thov yuav tsum tau ua. API 5L X60 yog nws tus kheej qhov tshwj xeeb tshwj xeeb rau kev kis lub raj xa pa.
** 5. Puas yog A53 qib B zoo dua li U500 Qib B? **
* ** "Zoo dua" yog nyob ntawm daim ntawv thov: **
* ** Rau cov piping siab: ** ** A53 qib B yog qhov zoo dua. ** Nws tau sim, thiab muaj ntawv pov thawj rau cov ntawv thov raws li cov ntawv tso cai raws li cov cim piping (piv txwv li, ASME B31). A500 yog cov qauv tub ua yeeb yam, tsis yog npaj lossis muab ntawv pov thawj rau cov piping siab.
* ** Rau cov ntawv thov teeb tsa: ** ** A500 qib B feem ntau zoo dua. ** Nws muaj qhov zoo tshaj plaws los ntawm cov tsev, txuas ntxiv rau cov tsev neeg, thiab lwm yam.
* ** Lawv tau tsim los rau cov hom phiaj sib txawv. ** Siv A500 rau cov piping siab yog qhov tsis zoo thiab ua txhaum cai. Siv A53 rau cov tswv cuab txheej txheem tseem ceeb yog qhov tsis muaj txiaj ntsig thiab tsis tuaj yeem ntsib cov qauv tsim qauv.
