P22 cov khoom siv yeeb nkab muaj qhov hnyav thiab siab hnav thiab tsim kua muag, nws tuaj yeem siv los tsim cov yeeb nkab fittings xws li lub luj tshib, tee, reducers hauv ASTM A234 WP22 chrome moly yeeb nkab fittings.
ASTM A335 Txuj Specification
ASTM A335 tshwj xeeb npog cov phab ntsa nominal thiab phab ntsa yam tsawg kawg nkaus seamless ferritc alloy-steel yeeb nkab npaj rau cov kev pabcuam kub. Cov yeeb nkab tau txiav txim rau qhov kev qhia tshwj xeeb no yuav tsum tsim nyog rau kev khoov, flanging (vanstoning), thiab kev ua haujlwm zoo sib xws, thiab rau fusion vuam. Kev xaiv yuav nyob ntawm tus qauv tsim, cov khoom siv kho tshuab, cov kev pabcuam thiab cov yam ntxwv ntawm qhov kub thiab txias.
Ferritic steels hauv qhov kev qhia tshwj xeeb no txhais tau tias yog cov hlau qis thiab nruab nrab-cov hlau uas muaj txog li thiab suav nrog 10% chromium.
