Njira Yopangira
DIN 17175 St45.8 mapaipi achitsulo osasunthika amatha kupangidwa ndi kugudubuza kotentha, kugudubuza kozizira, kukanikiza kotentha, kujambula kotentha kapena kujambula kozizira.
Mapaipi achitsulo amatha kusungunulidwa pamalo otseguka kapena ng'anjo yamagetsi molingana ndi njira yowombera mpweya, ndipo zitsulo zonse ziyenera kuponyedwa mokhazikika.
Kupezeka
17175 St45.8 chitoliro chopanda chitsulo chidzaperekedwa ndi chithandizo choyenera cha kutentha.Chithandizo cha kutentha chimaphatikizapo:
- Kukhazikika.
- Kuwongolera.
- Kutentha;kuchokera ku kutentha kozimitsa, sikuzizira, koma kupsa mtima.
- Sinthani misa ndi njira yosinthira isothermal.

Pepala lopyapyala liyenera kutengedwa kumapeto kwa mzere uliwonse wozungulira kapena square bar ingot kuti muyesedwe kuti muwone ngati kumapeto kwake kwadulidwa mokwanira.Akupanga kuyezetsa angathenso kuchitidwa pa dzenje shrinkage monga anasankha ndi katundu.
Yesani:
Mayeso otsimikizira kapangidwe kake
hydrostatic test
Tensile test
Notched impact test
Mayeso a mphamvu zokolola
Kuyesa kwa mphete
Kuyesa kosawonongeka
Mbendera ya Tube
Mipope yonse yachitsulo yomwe imaperekedwa kuti iyesedwe ndikuvomerezedwa idzalembedwa kumanzere ndi kumanja kwa mapeto a chitoliro pa 300 mm.Chizindikiro nthawi zambiri chimakhala nambala.Machubu okhala ndi mipanda yopyapyala amathanso kugwiritsidwa ntchito mwanjira zina.
Kulemba ndi kuyitanitsa
Gawo lachitsulo kapena nambala yazinthu iyenera kulembedwa ku chidule cha chinthucho monga momwe tawonetsera pachitsanzo chotsatirachi:
Chitsanzo 1:
