ASTM A358 CL.1 TPTIONS HLAU STINLET HLAU

ASTM A358 qhia meej txog kev tsim khoom rau hluav taws xob fusion welded stainless hlau kav dej stainless hlau.

Cl1: ib leeg {{{-} huab vuam (muab tub lim hlau tso cai), haum rau nruab nrab thiab qis {2}{{30}} qhov kev siv siab.

CL3: ob npaug {-}}} portoric (100% {3} {{4 4}} kub strararios.

 

ASTM A358 TPTPIONL FAGER WELDED PIPES Muab los ntawm Gnee yog tsim los siv hluav taws xob vuam cov txheej txheem (xws li Tig lossis Mig). Class 1 features single-side welding, while Class 3 requires double-side welding and radiographic inspection.​​ These pipes are adjusted in carbon content (0.04–0.10%) based on 304-grade stainless steel, with possible additions of niobium/titanium elements to enhance creep resistance. Lawv cov tshuaj chromium thiab cov npib tsib xee yog 18-20% thiab 8-11%, feem ntau, thiab lawv tau ua kom muaj kev ntxhov siab thiab thiab lawv muaj kev ntxhov siab ntau dua. Lawv tau ua raws li txoj hlua kev nruj yuav tsum muaj ntawm Astm A358 rau chav kawm 1/3. ASTM A358 chav kawm 3 tengeced kav dej feem ntau yuav tsum muaj ob sab weld kev tshuaj xyuas nrog 57-1626mm thiab phab ntsa thicknesses ntawm 1.2-60mm.

Dab tsi yog qhov txawv ntawm Astm A358 thiab ASTM A312?
ASTM A358 yog rau hluav taws xob {{1} {{welded-}} Welded (EFW) cov yeeb nkab ntawm ob leeg (Erded) stainless hlau. A358 feem ntau yog siv rau qhov loj dua qub thiab siab- {}}}} lub hom phiaj kev tsim nyog rau ntau cov ntawv thov.

 

Cov Ntawv Thov
Petrochemical: Siv nyob rau hauv high - kub, siab}} pa taws pipelines, uas xav tau kev tiv thaiv kom sov

Lub Zog Hluav Taws Xob thiab Lub Zog Hluav Taws Xob: Chav Piping Systems Rely ntawm nws cov creep tsis kam thiab ntev {}} lub sij hawm ruaj khov

LNG: Chav 3 kav ntev feem ntau siv nyob rau hauv cryogenic pipelines vim muaj kev sim nruj.
