Chiqgan po'lat, qotishmali po'lat, zanglamaydigan po'lat, mis, alyuminiy qotishma, pvc, PPR, RFPP (Temirlangan polipropilen) va boshqalar.
2. Ishlab chiqarish usuliga ko'ra, uni itarib, bosish, pikteptlash, quyish va hk.

4. Uning egilish radiusiga ko'ra: uni uzoq radius tirsagiga va qisqa radiusi tirsagiga bo'lish mumkin. Uzoq radiusni tirsa bay, uning egrilik radiusi 1,5 baravarga teng, ya'ni r =1; 5D; Qisqa radiusi tirsaklari uning egilish radiusi quvurning tashqi diametriga teng, ya'ni r 0 d. 0. (D tirsak diametri, R - bu egrilik radiusi). 5. Agar bosim darajasi bo'yicha tasniflangan bo'lsa: bu Amerika trubkasi, sch30, sch30, sch30, sm30, sm30, sms; Sch80, sch100, sch120, sch140, sm sm60, xxs; Eng ko'p ishlatiladiganlar std va XS.
