1. Incazelo Elula:
1) ASTM Standard A387/A387M-11 Chromium-Molybdenum Alloy Steel Sheets for Pressure Vessels Chemical Composition
Isimo Sokulethwa Kwezinga Lokushisa Okunomthelela Sijwayelekile + Sishubile/Sifakiwe.
2) Ibanga ngalinye i-excepi Amabanga 21L 22L kanye no-9 ayatholakala ama-intolasi wamazinga wamandla aqinile njengoba kuchazwe kumathebula Ezimfuneko Ze-Tensile.
Amabanga 21L kanye no-22L atholakala kuphela njengoba i-Class 1 Grade 91 itholakala kuphela njenge-Class 2. QAPHELA 1- IBanga 911, ngaphambilini elalifundiswa yilesi
imininingwane, manje imbozwa yi-Specification A1017/A1017M.
3) Ubukhulu obukhulu bamapuleti bukhawulelwe kuphela umthamo wokwakheka ukuze kuhlangatshezwane nezidingo zezakhiwo ezicacisiwe.

6. Ukulayishwa Kwesitsha:
7. Isicelo:
Inhloso eyinhloko yepuleti lesitsha elijwayelekile laseMelika: elisetshenziswa kabanzi ku-petroleum, amakhemikhali, esiteshini samandla, kubhayela nezinye izimboni,
asetshenziselwa ukwenza ama-reactors, izishintshi zokushisa, izihlukanisi, amathangi ayindilinga, amathangi kawoyela negesi, amathangi egesi anoketshezi, amagobolondo omfutho we-nuclear energy reactor,
ama-boilers Izigubhu ze-steam, amasilinda egesi kaphethiloli afakwe uketshezi, amapayipi amanzi anomfutho ophezulu weziteshi eziphehla ugesi ngamanzi, amavoluthi ophethroli nezinye izinto zokusebenza.
kanye nezingxenye.
