Kazhinji kutaura, API 5L inoreva API 5L mutsetse pombi, iyo iri kunze kwevhu mafuta, gasi, mvura, inotakurwa nepombi kumakambani epombi emafuta uye gasi indasitiri.

zvinoenderana nemaitiro ekugadzira uye chubhu inotumbuka yakashandiswa akasiyana maumbirwo, api 5l inogona kukamurwa kuita api 5l isina musono simbi pombi uye api welded simbi pombi, pakati pehuwandu hwekushandisa welded simbi pombi inopfuura seamless simbi pombi.

Mutsara pombi giredhi uye makemikari zvinoriumba

API 5L inogona kukamurwa kuita API 5L PSL 1 uye API 5L PSL 2, kusanganisira API 5L PSL 1 nhanho uye mapoka ndeaya: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 nhanho. uye chikamu ndeichi B, x42, x46, x52, x56, x60, x65, xx70, x80.iyo yakakwirira nhanho ndiyo yakasimba yemagetsi emagetsi.

Chikumbiro: inoshandiswa indasitiri yemafuta uye gasi, gasi, mvura, kutakura kwemafuta.

API SPEC 5L Mutsara Pipe

API SPEC 5L mutsetse pombi yekugadzira maitiro yakakamurwa kuita isina musono simbi pombi, ERW simbi pombi, yakadzika arc welded pombi.Asi iyo yakanyanya kushandiswa yesimbi isina musono pombi (iyo Seamless), yakatwasuka musono yakakwira frequency kuramba welding simbi pombi (Electric-Resistance Arc Welding, yakapfupikiswa seERW), LSAW (Longigudinally Submerged Arc Welding short LSAW), spiral yakanyura arc welded pombi (Spirally). Yakanyura Arc Welding, ipfupi yeSSAW) ina.
