90 graduslik zanglamaydigan po'latdan yasalgan tirsak hozirgi kunda keng tarqalgan bo'lib foydalaniladigan quvur ulanish elementlaridan biri bo'lib, u asosan quvurlar orasidagi ulanish darajasini oshirish uchun ishlatiladi. Biroq, ko'plab foydalanuvchilar tegishli bilimlar haqida ko'p narsa bilishmaydi. Quyida qisqacha tanishuv keltirilgan:
I. 90 daraja zanglamaydigan po'latdan yasalgan tirsak tasnifi:
1. Karbonli po'lat, zanglamaydigan po'lat, qotishma po'lat, mis va boshqalar.
2. Ishlab chiqarish usuliga ko'ra, uni surish, presslash, zarb qilish, quyish va boshqalarga bo'lish mumkin.
3. Ishlab chiqarish standartiga ko'ra, u milliy standart, neft-kimyo standarti, kimyoviy standart, amerika standarti, nemis standarti, yapon standarti va rus standartiga bo'linishi mumkin.
4. Egrilik radiusiga ko'ra, uzun radiusli 90 darajali zanglamaydigan po'latdan yasalgan tirsak va qisqa radiusli 90 daraja zanglamaydigan po'latdan yasalgan tirsakga bo'linishi mumkin. trubaning tashqi diametrining 1,5 barobariga, ya'ni R=1.5D.Qisqa radiusli 90 daraja zanglamaydigan po'latdan yasalgan tirsak uning egrilik radiusi quvurning tashqi diametriga teng ekanligini bildiradi, ya'ni R.=1.0d.(D - 90 daraja zanglamas po'latdan yasalgan tirsak diametri, R esa egrilik radiusi).
5. Bosim darajalariga ko'ra, Amerika quvurlari standartlari bilan bir xil bo'lgan taxminan 17 tur mavjud, ular orasida Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s va XS.Sch80, SCH100 mavjud. , Sch120, Sch140, Sch160, XXS;Eng ko'p ishlatiladigan ikkitasi STD va XS.
II. 90 daraja zanglamaydigan po'latdan yasalgan tirsakni shakllantirish jarayoni.
Issiq teglar: 90 daraja po'lat quvur tirsak, Xitoy 90 daraja po'lat quvur tirsak ishlab chiqaruvchilari, zavod
