ASTM A53 GR.B Seamless Steel Yeeb Nkab

ASTM A53 GR.B Seamless Steel Pipes Featured duab

Lus piav qhia luv luv:

ASTM A53 yog cov pa roj carbon steel alloy, siv los ua cov qauv hlau lossis rau cov kav dej tsis tshua muaj siab.Cov alloy specifications yog teem los ntawm ASTM International, nyob rau hauv specification ASTM A53 / A53M.

ASTM A53 Standard yog tus qauv tshaj plaws rau cov pa roj carbon steel kav. Cov pa roj carbon steel yeeb nkab feem ntau yog hais txog cov pa roj carbon ntau yog tsawg dua 2.11% yam tsis muaj txhob txwm tshaj tawm cov ntsiab lus ntawm cov hlau, nrog rau qib ntawm cov pa roj carbon monoxide yog ib qho ntawm cov hlau. Qhov tseem ceeb tshaj plaws los cuam tshuam rau nws lub zog ntawm cov hlau, hardness nce, thiab txo ductility, toughness thiab weld peev xwm.Tsis tas li ntawd, nws feem ntau kuj muaj me me ntawm silicon, manganese, sulfur, phosphorus ntxiv rau carbon.Piv nrog rau lwm hom hlau, nws yog qhov ntxov tshaj plaws, tus nqi qis, kev ua haujlwm ntau, qhov loj tshaj plaws.Haum rau nominal siab PN ≤ 32.0MPa, kub -30-425 ℃ dej, chav, cua, hydrogen, ammonia, nitrogen thiab roj av, thiab lwm yam xov xwm.Cov pa roj carbon steel yeeb nkab yog qhov ntxov tshaj plaws los siv cov khoom siv loj tshaj plaws hauv kev lag luam niaj hnub no.Lub ntiaj teb kev lag luam lub teb chaws, nyob rau hauv kev siv zog ua kom muaj zog tsawg alloy steel thiab alloy steel ntau lawm, uas yog heev mloog mus rau kev txhim kho qhov zoo thiab nthuav ntau yam ntawm ntau yam thiab siv.Tus nqi ntawm cov khoom tsim nyob rau hauv lub teb chaws 'tag nrho cov zis ntawm hlau, kwv yees li ntawm 80%, nws tsis yog tsuas yog dav siv nyob rau hauv lub tsev, txuas hniav, railways, tsheb, nkoj thiab txhua yam ntawm machinery manufacturing kev lag luam, tab sis kuj nyob rau hauv niaj hnub petrochemical. kev lag luam, kev tsim kho marine, kuj tau siv ntau heev.

Cov txheej txheem ntau lawm

Seamless steel yeeb nkab raug txheej txheem yog muab faib ua kub dov thiab txias seamless yeeb nkab.
1. Cov txheej txheem ntau lawm ntawm kub dov seamless steel yeeb nkab: raj billet → cua sov → perforation → peb-roller / cross-rolling & nruam dov → de-pipe → sizing → txias → straightening → hydraulic test → marking → seamless steel yeeb nkab nrog leverage cuam tshuam.
2. Cov txheej txheem tsim khoom ntawm cov khoom txias kos seamless steel raj: raj blank → cua sov → perforation → taub hau → annealing → pickling → oiling → ntau yam txias txias → blank raj → heat treatment → straightening → hydraulic test → marking → storage.

ASTM A53 yog cov pa roj carbon steel hlau, uas tuaj yeem siv los ua cov qauv hlau lossis rau cov kav dej tsis tshua muaj siab.

ASTM A53 (ASME SA53) carbon steel yeeb nkab yog ib qho tshwj xeeb uas npog seamless thiab welded dub thiab kub-dipped galvanized steel yeeb nkab nyob rau hauv NPS 1/8 "rau NPS 26. A 53 yog npaj rau siab thiab mechanical daim ntaub ntawv thiab kuj tau txais kev zoo tib yam. siv hauv chav dej, dej, roj, thiab cua kab.

A53 yeeb nkab los ntawm peb hom (F, E, S) thiab ob qib (A, B).
A53 Hom F yog tsim los nrog lub qhov cub tawg vuam lossis tej zaum yuav muaj qhov txuas txuas ntxiv (Qib A nkaus xwb)
A53 Hom E muaj hluav taws xob tsis kam vuam (Qib A thiab B)
A53 Hom S yog cov yeeb nkab seamless thiab pom hauv Qib A thiab B)

A53 Qib B Seamless yog peb cov khoom siv ntau tshaj plaws nyob rau hauv cov lus qhia no thiab A53 yeeb nkab feem ntau tau lees paub rau A106 B Seamless yeeb nkab.

ASTM A53 seamless steel yeeb nkab yog ib hom American standard hom.A53-F sib raug rau Tuam Tshoj cov khoom siv Q235, A53-A sib raug rau Tuam Tshoj cov khoom siv No.
