ASTM A501 Giredhi Bipombi yesimbi yekabhoni yakasungirirwa yakagadzirwa nekupisa uye isina musono ine simba rekudhonza risingasviki 448 MPa (65,000 psi) yekushandiswa kwakasiyana-siyana kwechivakwa.
ASTM A501ndeyekugadzira nekushanda kwemachubhu esimbi yekabhoni yakasungirirwa yakagadzirwa nekupisa uye isina musono yekushandisa pakuvaka.
Machubhu aya esimbi anogona kunge matema (asina kuputirwa) kana kuti akanyudzwa nemagetsi anopisa, ayo ekupedzisira anowedzera kuramba ngura kuburikidza nekuita kwekugadzirisa machubhu, zvichiita kuti akwanise kushandiswa munzvimbo dzakasiyana-siyana.
Mapaipi aya esimbi anoshandiswa zvakanyanya mumabhiriji, zvivakwa, uye mamwe mashandisirwo akawanda ekuvaka.
ASTM A501 inoronga mapaipi esimbi muzvikamu zvitatu,giredhi A, giredhi B, uye giredhi C.
Giredhi B ndiro rinoshandiswa zvakanyanya pamagiredhi matatu aya nekuti rinopa hunhu hwakaenzana hwekushandisa zvakawanda mukuvaka.
Simbi inofanira kugadzirwa namaitiro ekugadzira simbi ye okisijeni kana yemagetsi.
Simbi inogona kuumbwa muzvikamu zvesimbi kana kuti inogona kuumbwa netambo.
Kana simbi dzemhando dzakasiyana dzakaiswa muchimiro chakatevedzana, mugadziri wesimbi anofanira kuona chinhu chinoshanduka ochibvisa achishandisa nzira yakatarwa inoparadzanisa mhando dzacho zvakanaka.
Tubing inofanira kugadzirwa neimwe yenzira dzinotevera:musono; kupinza-kupinza-muhuni (kupinza kunoramba kuchiitwa); kupinza nemagetsi (ERW) kana kupinza arc pasi pemvura (SAW)zvichiteverwa nekudziisazve muchikamu chose uye kupisa kuchigadzirwa nekudzikisa kana kuumba, kana zvese zviri zviviri.
Maitiro ekubatanidza eSAW akakamurwa kuita zvikamu zviviri:LSAW(SAWL) uye SSAW (HSAW).
Kuumbwa kwechimiro chekupedzisira kunofanira kuitwa nemaitiro ekupisa.
Zvinotenderwa kuwedzera mushonga wekupisa unogadzirisa machubhu ane ukobvu hwemadziro hunopfuura 13mm [1/2 in].
