ASTM A501 Giredhi Binopisa-yakagadzirwa welded uye isina musono kabhoni simbi pombi ine shoma tensile simba re 448 MPa (65,000 psi) kune akasiyana siyana madhizaini ekushandisa.
ASTM A501ndeyekugadzira uye kuita kweiyo inopisa-yakagadzirwa welded uye isina musono kabhoni simbi tubing yezvimiro zvekushandisa.
Aya machubhu esimbi anogona kunge ari matema (asina kuvharwa) kana anopisa-akanyungudutswa galvanized, iyo yekupedzisira iyo yakawedzera kushomeka kwekudzivirira kuburikidza nekuita galvanizing process, ichiita kuti ive yakakodzera kune dzakasiyana siyana mamiriro ezvakatipoteredza.
Aya mapaipi esimbi anoshandiswa zvakanyanya mumabhiriji, zvivakwa, uye zvimwe zvakawanda zvakajairika zvimiro zvekushandisa.
ASTM A501 inoronga simbi pombi kuita mamakisi matatu,giredhi A, giredhi B, uye giredhi C.
Giredhi B ndiro rinonyanya kushandiswa pamagiredhi matatu nekuti rinopa zvakadzikama zvivakwa kune akawanda maumbirwo ekushandisa.
Simbi ichagadzirwa nebasic-oxygen kana electric-arc-furnace steel-making process.
Simbi inogona kukandwa mune ingots kana inogona kukanda tambo.
Kana simbi dzemagiredhi akasiyana dzichikandwa sequentially stranded, mugadziri wesimbi acharatidza mhedzisiro yekuchinja zvinhu uye oibvisa achishandisa nzira yakagadziriswa inoparadzanisa mamakisi zvakanaka.
Iyo tubing inogadzirwa neimwe yeanotevera maitiro:seamless;furnace-butt-welding (inopfuurira welding);electric resistance welding (RW) kana pasi pemvura arc welding (SAW)inoteverwa nekudziisa mukati memuchinjika-chikamu uye kupisa kuumbwa nekudzikisa kana kuumba maitiro, kana zvese zviri zviviri.
Iyo SAW welding process yakakamurwa kuitaLSAW(SAWL) uye SSAW (HSAW).
Chimiro chekupedzisira chimiro chichaitwa nekupisa kuumba nzira.
Ichave inotenderwa kuwedzera yakajairika kupisa kurapwa kwechubhu neukobvu hwemadziro kupfuura 13mm [1/2 mukati].
