Kodi mungatani kuti muyesere SML Pipe Tensile Test motsatira EN877?

Pa zinthu zopangidwa ndi chitsulo cha graphite chopangidwa ndi spheroidal, mphamvu yokoka iyenera kuyezedwa motsatiraEN 598:2007+A1:2009, 6.3. Pazinthu zopangidwa ndi chitsulo chotuwa kapena mtundu wina uliwonse wa chitsulo chotuwa, kudziwa mphamvu yokoka kuyenera kuchitika motsatira 2 kapena 3.

Fotokozani mphamvu yokoka pa mapaipi achitsulo chotuwa ndi zomangira

1. Zitsanzo

Kuti mupeze zotsatira zomwe zikugwirizana ndi zinthu zomalizidwa, mayeso omangika ayenera kuchitidwa pa zitsanzo:kapena kuchokera kuMapaipi a SMLkapena zolumikizira zachitsulo. Chitsanzocho chiyenera kudulidwa motsatira mzere wa chitolirocho kapena cholumikizira; kapena zokhazo zolumikizira, kuchokera ku zidutswa zoyesera zopangidwa padera, zoponyedwa nthawi imodzi ndi zolumikizirazo.

Chidutswa choyesera chomwe chadulidwa kuchokera ku chitsanzocho chiyenera kukhala chogwirizana ndi Zithunzi, ndipo ngati chachokera ku zidutswa zoyesera zopangidwa padera, chingakhale chosalala m'malo mopindika.

2. Zipangizo ndi Njira Yoyesera

Makina oyesera ayenera kukhala ndi zida zoyenera kuti alole kugwiritsa ntchito mphamvu yoyesera popanda kutsetsereka.
Makina oyesera ayenera kukhala ndi mphamvu yokwanira kuswa zidutswa zoyesera pamene akuwonetsa katundu wogwiritsidwa ntchito.
Kulondola kwa makina oyesera kuyenera kutsagana ndiEN IS0 6892-1:2019, Gawo 9.
Liwiro la katundu liyenera kukhala lofanana momwe zingathere malinga ndiEN IS0 6892-1:2019, Gawo 10.
Mphamvu yokoka iyenera kuwerengedwa pogawa mphamvu yomwe yasonyezedwa pakusweka ndi dera la gawo loyambira la chidutswa choyesera. Gawo lopingasa (m'lifupi ndi makulidwe) liyenera kuyezedwa molondola 0,1 mm mayeso asanayambe.

3. Kutsimikizika kwa Mayeso a Mphamvu Yolimba

Mayesowa amalengezedwa kuti ndi olondola ngati zinthu zotsatirazi zakwaniritsidwa:

• pa mapaipi: avareji ya zinthu zitatu zomwe zimatengedwa pakupanga kwa tsiku limodzi ziyenera kukhala osachepera 200 MPa ndipo mtengo umodzi wokha ungakhale pakati pa 180 MPa ndi 200 MPa;
• pa zolumikizira: mtengo wonse uyenera kukhala osachepera 150 MPa

Zotsatira za Mayeso Olimba

Dinani kuti muwone Kodi EN13501-1:2018 (DS SML PIPE A1) ndi chiyani?
