Mexanik sanoat standartida sirt yukining ta'rifi:

Mexanik sanoat standartida sirt yukining ta'rifi:

Isitish yuzasida birlik maydoniga to'g'ri keladigan quvvat, kvadrat santimetr uchun vattlarda o'lchanadi (Vt/sm²)

Isitish trubasining kuchini bilganimizda, bu quvvatni isitish trubasining isitish qismining sirt maydoniga bo'lish, isitish trubasining sirt yukini beradi.

Har bir material turli xil muhitda bardosh bera oladigan maksimal sirt yuki har xil, shuning uchun sirt yuki material tanlashda muhim elementga aylandi.

Shunday qilib, savol tug'iladi, biz materialning bardosh bera oladigan maksimal sirt yukini qanday bilamiz?

Yuqorida aytib o'tganimizdek, Internetda haqiqat va yolg'on ma'lumotlarni ajratish qiyin. Biroq, JB / T2379-2016 mexanik sanoat standartida, tez-tez ishlatiladigan muhitda tez-tez ishlatiladigan isitish trubkasi materiallarining maksimal ruxsat etilgan sirt yuki ko'rsatilgan, bu juda professional va mos yozuvlar qiymatiga ega. Shu bilan birga, issiqlik to'lqinli elektr isitish texnologiyasining o'n yildan ortiq ishlab chiqarish tajribasiga ham mos keladi:
