Alagbara Seamless Pipe
Lile:
Awọn tubes irin alagbara ni a lo nigbagbogbo lati wiwọn lile ti Brinell, Rockwell ati Vickers.Lile Brinell Lara awọn iṣedede paipu irin alagbara, irin alagbara, lile Brinell jẹ lilo pupọ julọ, ati lile ti ohun elo nigbagbogbo ṣafihan nipasẹ iwọn ila opin indentation, eyiti o jẹ intuitive ati irọrun.Sibẹsibẹ, ko dara fun awọn paipu irin ti irin lile tabi tinrin.
Rockwell lile:
Awọn irin alagbara, irin tube Rockwell líle igbeyewo jẹ kanna bi Brinell líle igbeyewo.Iyatọ naa ni pe o ṣe iwọn ijinle indentation.Idanwo líle Rockwell jẹ ọna lilo pupọ ninu eyiti HRC ti lo ni keji nikan si Brinell hardness HB ni awọn ajohunše paipu irin.Lile Rockwell le ṣee lo si ipinnu awọn ohun elo irin lati rirọ pupọ si lile pupọ.O isanpada fun ọna Brinell.O rọrun ju ọna Brinell lọ ati pe o le ka iye líle taara lati titẹ ti ẹrọ lile.Sibẹsibẹ, nitori itọsi kekere rẹ, iye líle ko ṣe deede bi ọna Brinell.
Vickers líle
Idanwo líle irin alagbara, irin Vickers tun jẹ ọna idanwo indentation fun wiwọn awọn ohun elo irin tinrin pupọ ati lile Layer dada.O ni awọn anfani akọkọ ti awọn ọna Brinell ati Rockwell, ati bori awọn ailagbara ipilẹ wọn, ṣugbọn kii ṣe rọrun bi ọna Rockwell.Ọna Vickers ṣọwọn lo ni awọn ajohunše paipu irin.
