Noocyadaxirmooyinka xaashida birta ah
Sida laga soo xigtay "Duulimaadyada xaashida birta ah ee kulul” (GB∕T 20933-2014), xaashida xaashida kulul ee duuban waxay ka kooban tahay saddex nooc, noocyada gaarka ah iyo magacyadoodu waa sidan soo socota:U-nooca xaashida xaashida birta ahMagaca koodka: PUZ-nooca xaashida birta ah ee tuulan, magaca koodhka: PZ xaashida birta toosan, magaca code: PI Xusuusin: halka P ay tahay xarafka ugu horreeya ee xaashida birta ee Ingiriisi (Pile), iyo U, Z, iyo I u istaag qaabka iskutallaabta ah ee tuulmada xaashida birta ah.
Tusaale ahaan, tuulista xaashida birta ee nooca U-nooca inta badan la isticmaalo, PU-400X170X15.5, waxaa loo fahmi karaa 400mm ballaaran, 170mm sare, 15.5mm qaro weyn.
Tusmada xaashida birta nooca z
U-nooca xaashida xaashida birta ah
Waa maxay sababta aysan ahayn nooca Z ama nooca tooska ah balse U-nooca inta badan loo isticmaalo injineernimada? Dhab ahaantii, sifooyinka farsamada ee nooca U iyo nooca Z asal ahaan waa isku mid hal hal, laakiin faa'iidada U-nooca xaashida xaashida birta ah waxay ka muuqataa ficil wadajir ah oo ah noocyo badan oo U-nooca xaashida birta ah.
Laga soo bilaabo shaxanka kor ku xusan, waxaa laga arki karaa in qallafsanaanta mitirka toosan ee U-nooca xaashida xaashida birta ah ay aad uga weyn tahay tan hal-nooca xaashida birta ah (booska dhidibka dhexdhexaadka ah ayaa loo beddelay wax badan) ka dib U- nooca xaashida birta ah ayaa la wada qaniinay.
2. Walxaha tuulmada xaashida
Heerka birta Q345 waa la joojiyay! Marka loo eego heerka cusub ee "Steel Alloy High High Structural Steel" GB/T 1591-2018, laga bilaabo Febraayo 1, 2019, darajada Q345 ee birta ah waa la joojiyay oo loo beddelay Q355, oo u dhiganta heerka EU S355 heerka birta.Q355 waa caadi. bir bir ah oo aad u hooseeya oo leh awood wax-soo-saarka 355MPa.
