Chitoliro chachitsulo chosasinthika cha API

Mafotokozedwe a API SPEC 5L amapereka miyezo yamapaipi oyenera kugwiritsidwa ntchito potumiza gasi, madzi, ndi mafuta m'mafakitale agasi ndi mafuta. API SPEC 5L imakwirira chitoliro chachitsulo chosasunthika komanso chowotcherera. Zimaphatikizapo chitoliro chomveka bwino, chopangidwa ndi ulusi, ndi chitoliro cha belled-end, komanso chitoliro chodutsa (TFL), ndi chitoliro chokhala ndi malekezero okonzekera kugwiritsidwa ntchito ndi zogwirizanitsa zapadera.

Kufotokozera	OD	6mm-660.4.4mm
	WT	1-80 mm
	Utali	1-12m

Chitoliro chopangidwa ku ASTM106 Giredi A kapena B sichisinthana ndi API 5L. Zofunikira pamagulu a API 5L X ndizokhazikika; magiredi ogubuduzika sizovomerezeka ndipo kukonzanso sikuloledwa. Kuphatikiza apo, chidwi chimaperekedwa pakuyesa kulimba komanso kulimba kwa ntchito zowawasa komanso makalasi apamwamba komanso kutentha.

Milingo Yamphamvu & Desulphurization

Manganese sulfide ndizomwe zimaphatikizidwa muzitsulo zonse za manganese alloyed. Chifukwa amakonda kupatukana zomwe zimapangitsa kuti mphamvu ya sulfure ikhale yochepa, sulfure iyenera kuchepetsedwa. Timalongosola zopitirira 0.007%.

API 5L Benefits & Applications Kuyendera gasi, madzi ndi mafuta - zokondedwa pamapaipi aatali chifukwa chotsika mtengo
Chitsulo chapaipi - kukana kufalikira kwa ming'alu
Line Pipe / Sour Service Line Pipes API Standard Specification ya Line Pipe

American Petroleum Institute specification API 5L imayankhulira chitoliro chachitsulo chosasunthika komanso chowotcherera pamapaipi oyendetsa mapaipi m'mafakitale amafuta ndi gasi. API 5L ndiyoyenera kutumiza gasi, madzi, ndi mafuta.

Zofotokozera za API 5L zimatsatiridwa ndi International Organisation for Standardization ISO 3183, kuyimilira machitidwe amapaipi mkati mwa zida, zida ndi zida zakunyanja zama gasi achilengedwe, mafuta amafuta, ndi mafakitale amafuta. Polemba miyezo, komiti yaukadaulo idazindikira kuti pali ma Level Specifications Levels (PSL) ofunikira zaukadaulo motero adapanga PSL 1 ndi PSL 2.  PSL 1 ndi mtundu wokhazikika wa chitoliro pomwe PSL 2 imakhala ndi mankhwala owonjezera, makina amakina. , ndi zofunika kuyesa.

Magiredi ophatikizidwa ndi izi ndi A25, A, B ndi "X" Magiredi X42, X46, X52, X56, X60, X65, X70, ndi X80. Nambala ziwiri zotsatizana ndi "X" zikuwonetsa Mphamvu Zochepa Zokolola (mu 000's psi) za chitoliro chopangidwa mpaka giredi iyi.
