ASTM A871 / A871M chitsulo

Mafotokozedwe a ASTM A871 ndizomwe zimapangidwira mbale zachitsulo zamphamvu zotsika kwambiri zokhala ndi kukana kwa kutu mumlengalenga zomwe zimagwiritsidwa ntchito pamapangidwe a tubular ndi mitengo. Magiredi 60 ndi 65 amapezeka m'malo ogubuduzika, okhazikika, kapena ozimitsidwa komanso osasunthika momwe amafunikira kuti akwaniritse zomwe zidanenedwazo.

Mafotokozedwe:
makulidwe: 3mm-150mm
M'lifupi: 30mm-4000mm
Utali: 1000mm--12000mm
Standard: ASTM EN10025 JIS GB

A871 Giredi 65 atha kuperekedwa ngati-yokulungidwa, yokhazikika kapena yozimitsidwa ndi kupsya mtima.
