ASTM A335 P11 yog ib qho kev qhia tshwj xeeb tsim los ntawm American Society for Testing and Materials (ASTM) uas cuam tshuam rau seamless ferritic alloy steel yeeb nkab rau kev pabcuam kub. Cov qib tshwj xeeb ntawm cov yeeb nkab steel no paub txog nws qhov kev ua tau zoo hauv qhov chaw siab-kub, ua rau nws muaj kev xaiv nrov hauv kev lag luam xws li kev tsim hluav taws xob, petrochemical, thiab refineries.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm ASTM A335 P11 yog nws cov alloy muaj pes tsawg leeg, uas suav nrog cov ntsiab lus xws li chromium thiab molybdenum. Cov ntsiab lus alloying no txhawb cov khoom siv kho kom zoo thiab kev tiv thaiv corrosion, tshwj xeeb tshaj yog thaum raug kub thiab siab. Yog li ntawd, qhov kev qhia tshwj xeeb no yog qhov tshwj xeeb zoo rau cov ntawv thov uas muaj xwm txheej hnyav heev.
ASTM A335 P11 cov kav dej yog seamless, uas txhais tau hais tias lawv tsis muaj cov vuam seams pom nyob rau hauv welded kav. Qhov kev tsim kho seamless no muaj ntau qhov zoo, suav nrog kev txhim kho lub zog thiab txo qis kev cuam tshuam rau kev tawg thaum muaj kev ntxhov siab. Lub npe P11 qhia txog cov tshuaj muaj pes tsawg leeg hauv A335 specification, kom ntseeg tau cov khoom siv meej.
Cov kav dej no feem ntau yog siv rau hauv cov chaw tsim hluav taws xob rau cov khoom siv xws li boiler tubes thiab superheater thiab reheater tubes, qhov uas lawv yuav tsum ua kom muaj qhov kub thiab txias thiab qhov chaw corrosive. Tsis tas li ntawd, ASTM A335 P11 tau txais kev pom zoo rau nws txoj kev sib raug zoo nrog cov txheej txheem vuam, ua rau nws muaj ntau yam kev xaiv rau kev tsim cov kav dej.
Nyob rau hauv cov ntsiab lus, ASTM A335 P11 yog ib tug zoo-tsim specification rau seamless alloy steel kav uas zoo heev nyob rau hauv high-kub thiab high-pressure daim ntaub ntawv nyob rau hauv ntau yam industries, muab durability, kev cia siab, thiab kev ua tau zoo heev.
