Chitoliro cha API 5L chimatanthauza chitoliro cha chitsulo cha kaboni chomwe chimagwiritsidwa ntchito mumakina otumizira mafuta ndi gasi. Chimagwiritsidwanso ntchito kunyamula madzi ena monga nthunzi, madzi, ndi matope.

Mitundu Yopangira

Mafotokozedwe a API 5L amakhudza mitundu yonse ya zomangira zolumikizidwa komanso zopanda msoko.

Mitundu Yowotcherera: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe

Mitundu yodziwika bwino ya chitoliro cholumikizidwa cha API 5L ndi iyi:

ERW: Kuwotcherera kolimba kwa magetsi kumagwiritsidwa ntchito pa chitoliro chokhala ndi mainchesi osakwana 24.

DSAW/ SAW: Kuwotcherera arc yolumikizidwa mbali zonse ziwiri/kuwotcherera arc yolumikizidwa pansi ndi njira ina yowotcherera yomwe ingagwiritsidwe ntchito m'malo mwa ERW pa chitoliro chachikulu.

LSAW: Kuwotcherera kwa Arc Yokhala ndi Madzi a Longitudinal komwe kumagwiritsidwa ntchito pa chitoliro chofika mainchesi 48 m'mimba mwake. Kumadziwika kuti njira yopangira JCOE.

SSAW/HSAW: Kuwotcherera kwa arc yozungulira/kuwotcherera kwa arc yozungulira mpaka mainchesi 100 m'mimba mwake.

Lumikizanani nafe kuti mudziwe kusiyana pakati pa chitoliro cha ERW, LSAW, ndi SSAW.

Mitundu ya Mapaipi Opanda Msoko: Chitoliro Chopanda Msoko Chotentha ndi Chitoliro Chopanda Msoko Chozizira

Chitoliro chopanda msoko nthawi zambiri chimagwiritsidwa ntchito pa mapaipi ang'onoang'ono a m'mimba mwake (nthawi zambiri osakwana mainchesi 24).

(Chitoliro chachitsulo chopanda msoko chimagwiritsidwa ntchito kwambiri kuposa chitoliro cholumikizidwa pa mapaipi okhala ndi mainchesi osakwana 150 mm (mainchesi 6).

Timaperekanso chitoliro chachikulu chopanda msoko. Pogwiritsa ntchito njira yopangira yotenthetsera, titha kupanga chitoliro chopanda msoko chofika mainchesi 508 (508 mm) m'mimba mwake. Ngati mukufuna chitoliro chopanda msoko chopitirira mainchesi 20 m'mimba mwake, titha kuchipanga pogwiritsa ntchito njira yotenthetsera yofika mainchesi 1016 (1016 mm) m'mimba mwake.

API 5L Chitoliro Giredi

API 5L imafotokoza magiredi otsatirawa: Giredi B, X42, X46, X52, X56, X60, X65, X70, ndi X80.

Pali mitundu yosiyanasiyana ya chitsulo cha API 5L monga Giredi B, X42, X46, X52, X56, X60, X65, X70, ndi X80. Ndi kuwonjezeka kwa giredi yachitsulo, kuwongolera kofanana ndi kaboni kumakhala kolimba kwambiri, mphamvu yamakina imakhala yokwera.

Komanso, kapangidwe ka mankhwala a mapaipi a API 5L osasemphana komanso olumikizidwa a mtundu winawake sikofanana, chitoliro cholumikizidwa chili ndi zofunikira zambiri komanso kaboni ndi sulfure zochepa.

PSL1 ndi PSL2 zimasiyana pamlingo woyesera komanso mu kapangidwe kake ka mankhwala ndi makina.

PSL2 ndi yokhwima kwambiri kuposa PSL1 pakupanga mankhwala, mphamvu zomangirira, mayeso okhudzika, mayeso osawononga ndi zina zotero.
Kuyesa Zotsatira

PSL2 yokha ndiyo imafunika kuyesa kukhudzidwa: kupatula X80.

NDT: Kuyesa Kosawononga. PSL1 sikufuna kuyesa kosawononga ngati pali kuchotsera. Kuyesa kosawononga kumagwiritsidwa ntchito. PSL2 imafuna.

(Kuyesa kosawononga: Kuyesa kosawononga mu muyezo wa API 5L kumagwiritsa ntchito njira zowunikira pa wailesi, ultrasound, kapena njira zina (popanda kuwononga zinthuzo) kuti zizindikire zolakwika ndi zolakwika m'mapaipi.)

Kuti mudziwe zambiri, titumizireni uthenga kuti mudziwe zambiri za kusiyana pakati pa API 5L PSL1 ndi PSL2.
