90 degre koud asye pur se youn nan eleman yo koneksyon tiyo lajman itilize kounye a, ki se sitou itilize pou koneksyon ki genyen ant tiyo, konsa tankou amelyore degre nan patant ant tiyo. Sepandan, anpil itilizatè pa konnen anpil bagay sou konesans ki enpòtan yo. Sa ki anba la a se yon entwodiksyon tou kout:
I. 90 degre en fe koud klasifikasyon:
1. Kabòn asye, asye pur, asye alyaj, kwiv, elatriye.
2. Dapre metòd pwodiksyon an, li ka divize an pouse, peze, fòje, depoze, elatriye.
3. Dapre estanda fabrikasyon an, li ka divize an estanda nasyonal, estanda petwochimik, estanda chimik, estanda Ameriken, estanda Alman, estanda Japonè ak estanda Ris.
4. Dapre reyon koub li yo, li ka divize an reyon long 9 0 degre koud asye pur ak kout reyon 90 degre koud asye pur. Long reyon 90 degre koud asye pur refere a reyon koub li yo egal. a 1.5 fwa dyamèt deyò tiyo a, se sa ki, R=1.5D.Yon kout reyon 90 degre koud asye pur vle di ke reyon koub li egal a dyamèt ekstèn tiyo a, se sa ki, R.=1.0d.(D se dyamèt koud asye pur 90 degre, ak R se reyon koube).
5. Dapre nivo presyon yo, gen apeprè 17 kalite, ki se menm jan ak estanda tiyo Ameriken yo, ki gen ladan Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s ak XS.Sch80, SCH100. , Sch120, Sch140, Sch160, XXS; De ki pi souvan itilize yo se STD ak XS.
Ii. 90 degre Nerjaveèi asye koud fòme pwosesis.
Baj popilè: 90 degre asye tib koud, Lachin 90 degre asye tib koud manifaktirè, faktori
