S275jr Qauv ERW Hlau Yeeb Nkab

S275JR Structural Welded Pipe Taw Qhia

S275JR steel yeeb nkab yog ua los ntawm ib qho yooj yim -rau- vuam qis- carbon manganese steel nrog ntxiv tooj liab los txhim kho nws lub zog. S275JR seamless steel yeeb nkab tau dhau ISO 9000-2001 series certifications nrog rau API certifications xws li CE, CCS, PED, thiab UKAS. TS EN 10025 S275JR steel yeeb nkab yog qhov kev xaiv zoo tshaj plaws rau qis - thiab cov kav dej nruab nrab hauv kev lag luam xws li tshuaj thiab chiv.

Qhov zoo ntawm S275JR Structural Welded Pipe

Ob leeg S275JR thiab S355 yog cov qauv hlau, tab sis lawv qhov kev tawm dag zog yam tsawg kawg nkaus txawv. S275JR muaj lub zog tawm los ntawm 275 N / mm² (li no nws lub npe), thaum S355 steel muaj lub zog tawm los ntawm 355 N / mm². Qhov no yog vim lawv cov tshuaj sib txawv; S355 muaj cov ntsiab lus carbon ntawm 0.20%, qis dua S275JR's 0.25%.

S355 muaj tib yam manganese cov ntsiab lus xws li S275JR, ntawm 1.6%, tab sis nws cov silicon (0.55%), sulfur (0.25%), thiab phosphorus (0.25%) cov ntsiab lus yog tag nrho siab dua S275JR (0.505%, 0.04% feem).

Txawm hais tias S275JR steel yeeb nkab muaj lub zog qis dua li S355 steel, nws boasts zoo weldability thiab yog dav siv.

Ob lub ASTM A 36 thiab S275JR steel kav yog ua los ntawm cov hlau tsis muaj - carbon steel thiab feem ntau siv hauv kev tsim kho kev lag luam. Qhov no yog vim hais tias lawv cov compositions yuav luag zoo tib yam, ua rau muaj ntau yam khoom sib koom. Txawm li cas los xij, muaj qee qhov sib txawv ntawm A 36 thiab MS S275JR steel kav, suav nrog cov hauv qab no:

S275JR steel kav muaj ntau dua manganese thiab tooj liab ntau dua li A36 steel (1.50% thiab 0.55%, feem).

S275JR EN 10025 square tubing muaj cov ntsiab lus qis dua (21-22%) dua li A36 steel (25-29%).

S275JR steel kav muaj zog tensile thiab yield zog dua A36 steel kav, ua rau lawv nrov nyob rau hauv ntau industries.

S275JR steel kav ua tau zoo dua lwm yam qis - carbon steel kav, ua rau lawv nyiam cov khoom siv rau ntau daim ntawv thov. Vim lawv cov load ntau dua -cov kabmob muaj peev xwm, lawv muaj ntau yam kev siv, suav nrog:

Lawv yog cov zoo tagnrho rau qis -load Cheebtsam nyob rau hauv mechanical manufacturing, xws li shafts, axles, thiab bushings.

Nws yog tsim rau ntau yam kev siv, los ntawm petrochemicals thiab kev lag luam tshuaj, mus rau boilers, kws, thiab hluav taws xob kev lag luam.

Nws daim ntawv thov yog dav heev, xws li kev tsim kho choj thiab kev tsheb ciav hlau ntsuas thiab lub tank cia rau ntau yam tshuab engineering.
