I-ASTM A387 Gr11 CL2N Isitya sentsimbi yentsimbi, ipleyiti yentsimbi yealloyi
1. Ingcaciso elula:
1) Umgangatho we-ASTM we-A387/A387M-11 Chromium-Molybdenum Alloy Steel Sheets for Pressure Vessels Ukubunjwa kwemichiza
IMpembelelo yoBonelelo lweMeko eQinisekisiweyo + Bubushushu/buAnnealed.
2) Ibakala ngalinye le-excepi kumaBakala 21L 22L no-9 liyafumaneka kwii-intolasi zamanqanaba okuqina okuqina njengoko kuchaziwe kwiitheyibhile zeeMfuno zeTensile.
Grades 21L and 22L afumaneka kuphela njengoko Class 1 Grade 91 ifumaneka kuphela Class 2. QAPHELA 1- Grade 911, ngaphambili kufundiswa le
iinkcukacha, ngoku zigutyungelwe yi-Specification A1017/A1017M.
3) Ubukhulu bobukhulu beepleyiti bukhawulelwe kuphela ngumthamo wokwakheka ukuhlangabezana neemfuno zepropathi zoomatshini.
2. Ukuqulunqwa kwemichiza:

4. UMboniso weMifanekiso:
5. Ukuhanjiswa:
6. Ukufakwa kwesikhongozeli:
7. Isicelo:
Eyona njongo iphambili yesitya sesitya esisemgangathweni saseMelika: sisetyenziswa kakhulu kwipetroleum, kwikhemikhali, kwisikhululo samandla, kwibhoyila kunye namanye amashishini,
ezisetyenziselwa ukwenza iiactors, izitshintshi zobushushu, izahluli, iitanki ezingqukuva, iitanki zeoyile nerhasi, iitanki zerhasi enyibilikisiweyo, amaqokobhe oxinzelelo lwesixhobo senyukliya,
iibhoyila Imigqomo yomphunga, iisilinda zegesi yepetroleum elulwelo, imibhobho yamanzi enoxinzelelo oluphezulu lwezikhululo zombane wamanzi, iivoluthi zeinjini yomoya kunye nezinye izixhobo.
kunye namacandelo.
