Píobán Alloy ASTM A335 le haghaidh Ardteocht
Nov 05, 2025
Clúdaíonn an tsonraíocht A335/A335M píobáin déanta as cruach gan uaim cóimhiotal ferritic atá beartaithe le haghaidh seirbhíse ardteochta, lena n-áirítear tiús balla ainmniúil agus tiús bhalla íosta. Beidh píopaí a ordaítear don tsonraíocht seo oiriúnach le haghaidh lúbadh, bladhmadh (táthú gáis), agus oibríochtaí foirmithe comhchosúla, chomh maith le táthú comhleá. Beidh an roghnú bunaithe ar dhearadh, ar dhálaí seirbhíse, ar airíonna meicniúla agus ar shaintréithe ardteochta.

1/8 go 2 1/2 [6 go 65] san áireamh, gach cóimheas t/D: os cionn 20%, faoi 12.5%
Os cionn 2 1/2 [65], t/D < nó=5 %: os cionn 22.5%, faoi 12.5%
Os cionn 2 1/2 [65], t/D > 5%: os cionn 15%, faoi 12.5%

Clúdaíonn an tsonraíocht seo balla ainmniúil agus cóimhiotal ferritic gan uaim balla íosta-píobán cruach atá beartaithe le haghaidh seirbhíse ardteochta. Beidh píopa ASTM A335 a ordaítear don tsonraíocht seo oiriúnach le haghaidh táthú comhleá, lúbthachta, flanging (vanstoning), agus oibríochtaí foirmithe comhchosúla.
