Kodi tanthauzo la ASTM API 5L Gr.b ndi chiyani?

WOPANGA WA ASTM API 5L Gr.b STEEL PIPE KU CHINA

WOPANGA WA ASTM A106 Gr.b POPHUNZIRA ZOCHITA ZOSAVUTA

KUSINTHA KWA ASTM API 5L Gr.b SCH 40 SCH 80

MTENGO WABWINO WA ASTM A53 B CARBON STEEL PIPE

API 5L ndi chiyani:
The American Petroleum Institute (API),idakhazikitsidwa mu 1919,ndi bungwe lalikulu kwambiri lamafuta amafuta ndi gasi ku United States.

5L imayimira chiyani:
5L imayimira mipope yachitsulo: - Mwachidule, mzere wa API 5L ndi chitoliro chachitsulo cha kaboni chomwe chimagwiritsidwa ntchito pamakina otumizira mafuta ndi gasi.Pakalipano zakumwa zosiyanasiyana monga nthunzi, madzi, slurry zingathenso kutenga API 5L monga momwe zimakhalira pofalitsa.Mawonekedwe apulogalamu 5L mwatsatanetsatane amakhudza mitundu yosonkhanitsidwa mu welded komanso mosasinthasintha.American Petroleum Institute mwatsatanetsatane API 5L imakwirira chitoliro chachitsulo chokhazikika komanso chowotcherera.Ichi ndi chitoliro chachitsulo chamayendedwe oyendera mapaipi mumafuta amafuta ndi gasi woyaka moto.Pulogalamu ya 5L ndiyoyenera kupatsira gasi, madzi, ndi mafuta.Mawonekedwe a Programming Spec 5L ndi Mulingo Wapadziko Lonse womwe umatsimikizira zoyambira pakuphatikiza magawo awiri atsatanetsatane.

Dziwani zambiri za PSL 1 ndi PSL 2:
PSL 1 ndi PSL 2 ndi mapaipi achitsulo osasinthasintha komanso owotcherera kuti agwiritsidwe ntchito pamapaipi amayendedwe pamabizinesi amafuta ndi gasi.
PSL1 nthawi zambiri imagwiritsidwa ntchito yomwe ili yofanana ndi ASTM A106 B ndi A53 B.
PSL2 ili ndi mtengo wokhazikika pamankhwala ndi makina.Kupitilira PSL2 kumafunikira njira zoyesera zambiri monga None Distructive Test, CVN Impact Test, DWT etc.
Magiredi ophatikizidwa ndi izi ndi magiredi A25 okhazikika,A,B,x42,x46,X52,x56,X60,x65,X70 ndi X80;ndi magiredi aliwonse apakati.

Zambiri za API 5L:
Mafotokozedwe a API SPEC 5L amapereka miyezo ya chitoliro choyenera kugwiritsidwa ntchito potumiza gasi, madzi, ndi mafuta m'mafakitale a gasi ndi mafuta.API SPEC 5L imakwirira chitoliro chachitsulo chosasunthika komanso chowotcherera.Zimaphatikizapo chitoliro chomveka bwino, chopangidwa ndi ulusi, ndi-belled-end chitoliro, komanso chitoliro chodutsa (TFL), ndi chitoliro chokhala ndi malekezero okonzekera kugwiritsidwa ntchito ndi zolumikizana zapadera.

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.

Mapulogalamu a API 5L:
Mayendedwe a gasi, madzi ndi mafuta - amakondedwa pamapaipi aatali chifukwa cha kutsika mtengo kwa Pipeline chitsulo - kukana kufalikira kwa ming'alu.

Mukalumikizidwa API 5L Gr.b kapena A106 Gr.b chitoliro chachitsulo, zolumikizira zina ndi flange zitha kulowetsedwa m'malo ndikusinthana.Ngati ndiwelKutsata zopangira za ASTM A105 zachitsulo zachitsulo monga zopangira mapaipi, ma flanges, zomangira ndi ma gaskets.JINBAICHENG METALndi ogulitsa wabwino, timagulitsa ndikupereka mitundu yonse ya API 5L Grade B Mipaipi Yopanda Pamaso ndi Mapaipi Owotcherera, A106 Gr.B mapaipi opanda msoko okhala ndi kuchuluka kokwanira komanso mtengo wotsika, talandilani kutiimbira foni.
