API 5L Grade B Carbon Steel Pipe Line Pipe

API 5L Grade B Carbon Steel Pipe Line Chitoliro Chowonetsedwa

Kufotokozera Kwachidule:

Chitoliro chachitsulo cha API 5L Gulu B ndi chitoliro wamba wamba wamapaipi amafuta ndi gasi.Imadziwikanso kuti chitoliro cha L245, chotchulidwa ku ISO 3183, chomwe chimatchedwanso mphamvu zokolola zochepa za 245 Mpa (355,000 Psi).

Zofananira za ASTM A106 B kapena ASTM A53 B zokhala ndi mtengo wofanana pamapangidwe amankhwala, makina amakina ndi kugwiritsa ntchito.

API 5L B imakwirira PSL1, PSL2, ntchito zowawa za mapaipi akumtunda ndi kunyanja.Mitundu yopangira zinthu imakhala yopanda msoko komanso yowotcherera.

Chiyambi cha Zamalonda

PSL1, PSL2 ndi Acidic Media Types.

Nthawi zambiri PSL1 imagwiritsidwa ntchito, yomwe ili yofanana ndi ASTM A106 B ndi A53 B.

PSL2 ndi chitoliro chapamwamba chapamwamba chomwe chili ndi zofunikira zokhwima zamakina ndi mphamvu zamakina.PSL2 imafuna njira zambiri zoyesera monga kuyesa kosawononga, kuyesa kwamphamvu kwa CVN, DWT, ndi zina zambiri.

API 5L B PSL2 ikuimiridwa ndi API 5L BN/Q/R/M.

Acidic sing'anga: Kwa mapaipi a asidi monga chilengedwe cha H2S, zinthu zapaipi zimakhala ndi zofunikira pazamankhwala monga mpweya, phosphorous ndi sulfure.NACE MR0175.

Chiwonetsero cha Zamalonda

Suffix Letter

Malembo omangika amafotokoza momwe mapaipi amaperekera:

R: Pamene akugudubuza.

N: normalizing kugudubuza, normalizing kupanga, normalizing.

Q: Kutentha ndi kuzizira.

M: Thermomechanical rolling kapena thermomechanical kupanga.

S: Sing'anga yowawasa yokhala ndi machubu a PSL2 a NS, QS, MS, mwachitsanzo API 5L Grade B NS, API 5L B QS.

Mitundu yopanda msoko komanso yowotcherera (RW, LSAW, SSAW/HSAW).

Mtundu wa Zamalonda

Mtundu Wopanda Msoko:kuphatikiza mapaipi opanda msoko otenthedwa opitilira mainchesi atatu, mapaipi opanda msoko ozizira osakwana mainchesi atatu.

Mtundu Wowotcherera wa ERW:Resistance Welding, yoyenera mapaipi mpaka mainchesi 24.

Mtundu Wowotcherera Msoko Wowongoka wa Arc:Longitudinal segmented arc kuwotcherera, oyenera mapaipi okhala ndi mainchesi 20 mpaka 48 mainchesi.LSAW imadziwikanso kuti JCOE, kutanthauza kupanga mawonekedwe kuchokera kumapaipi owoneka ngati J, owoneka ngati C, owoneka ngati O, kenako mapaipi owonjezera ozizira.

Mtundu wa SSAW/HSAW:Spiral Submerged Arc Welding kapena Spiral Saw ya chitoliro mpaka 100" OD.

API 5L Grade B, ASTM A106 Grade B ndi A53 Grade B, zida zitatuzi ndizomwe zimagwiritsidwa ntchito kwambiri pomanga mapaipi kapena mafakitale amafuta ndi gasi ndi zamadzimadzi.

Chitoliro cha ASTM 106 chimatanthawuza chitoliro chachitsulo chotenthedwa kapena chozizira (chogudubuzika) chopanda mpweya.

Chitoliro cha ASTM A53 chimaphatikizapo mapaipi achitsulo opangidwa ndi chitsulo chakuda, komanso nthawi zina otentha-kuviika kanasonkhezereka (malata).
