API 5L Chitoliro Chopanda Msokonezo

API 5L Seamless Steel Pipes-Advanced Pipe Manufacturing Technology

Octal Pipe imapanga mayankho athunthu a API 5L Line Pipe, ophatikiza mapaipi achitsulo opanda msoko komanso owotcherera opangira makina oyendera mafuta ndi gasi. Kuthekera kwathu pakupanga kumayambira pa API 5L Gr B mpaka X80, yomwe imapezeka mumitundu yonse ya PSL1 ndi PSL2. Mapaipiwa amapangidwa kuti azifuna kugwiritsa ntchito kumtunda/kunyanja komanso malo ochitira zinthu zowawa (H2S corrosive conditions with NACE compliance).
API 5L Line Pipe imathandizira mafakitale amafuta ndi gasi okhala ndi mayankho amphamvu a mapaipi opangidwira malo osiyanasiyana ogwirira ntchito. Ntchito yomanga zitsulo za kaboni imatsatira zofunikira za API SPEC 5L, kuwonetsetsa kuti ikugwira ntchito modalirika m'malo otentha kwambiri, malo owononga, ndi ntchito zowawa zomwe zili ndi H2S.

Seamless Steel Line Pipe
Amapangidwa pogwiritsa ntchito njira zotentha-zogudubuzika komanso zozizira (zogudubuzika), zomwe zimapezeka m'mimba mwake mpaka mainchesi 40. Kumanga kopanda msoko kumachepetsa kuopsa kwa weld seam, kumapereka kudalirika kwapamwamba pakugwiritsa ntchito{3}}zovuta kwambiri.
Welded Steel Line Pipe
Amapangidwa pogwiritsa ntchito njira zamakono zowotcherera monga ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), ndi njira za SSAW (Spirally Submerged Arc Welding), zomwe zimapereka mtengo-zothetsera zogwira mtima zogwiritsira ntchito zokakamiza.

Zofunikira Zopangira Chemical

Chitoliro cha ma welded chitoliro chimasunga magawo owongolera okhwima poyerekeza ndi mitundu ina yopanda msoko, ndikuwonetsetsa kuti zinthu sizisintha panthawi yonse yopangira. Mpweya wa kaboni, manganese, phosphorous, ndi sulfure zimayendetsedwa bwino kuti zigwirizane ndi API 5L.

Ma Mechanical Performance Properties

Mphamvu zokolola ndi mphamvu zolimba zimakhalabe zosagwirizana pakati pa mitundu yopanda msoko ndi yowotcherera m'makalasi ofanana. Mawonekedwe amakina amatsimikiziridwa kudzera mumayendedwe oyesera kuti awonetsetse kuti akutsatira zofunikira za API 5L.

Kulekerera kwa Diameter Yakunja:
a. M'mimba mwake <60.3mm (2⅜"): Kulekerera kwa chitoliro ± 0.5mm, Kutha kwa chitoliro ± 0.5mm; kulolerana kozungulira 0.9mm (thupi), 0.6mm (mapeto) b. Makulidwe 60.3mm mpaka 610mm: Kulekerera kwathupi ± 0.00075D ± 0.00075D ± 1.6mm Kuzungulira Kuchepera kapena kofanana ndi 0.015D (thupi), Ochepera kapena ofanana ndi 0.01D (mapeto)
Kulolera kwa Wall Makulidwe:

• < 4mm: +0.6mm, -0.5mm tolerance
• 4mm mpaka 10mm: +0.150t, -0.125t kulolerana
• 10mm mpaka 25mm: ± 0.125t kulolerana
• Chachikulu kuposa kapena chofanana ndi 25mm: +3.7mm kapena +0.1t (chilichonse chachikulu), -3.0mm kapena -0.1t (chilichonse chachikulu)

Zofunikira Zowongoka:

• Kupatuka kwautali wonse: 0.15% ya kutalika konse
• Kupatuka kwa mapaipi: Ochepera kapena ofanana ndi 0.3mm/mita
• Standard kutalika kulolerana: ± 200mm (yambiri), ± 25.4mm (ntchito yapadera)

Njira Zopangira Mapaipi Opanda Msoko
Hot-Njira Yosasinthasintha:

Njira Yokokedwa Yozizira/Yozungulira:Kukonzekera Chitoliro cha Amayi → Kuyendera → Kuwonjeza → Kuthetsa Chithandizo → Kutola → Kutola → Kugaya → Phosphorization → Kujambula Kozizira/Kugudubuza → Kuyeretsa & Kuwotcha → Kuchiza Kutentha → Kuwongola → Kuyeza kwa Hydrostatic → Kulemba Chizindikiro & Kupenta → Kusungirako

Njira Zopangira Mapaipi Owotcherera
ERW Manufacturing (Ochepera kapena ofanana ndi 24" awiri):

LSAW/JCOE Manufacturing (20"-40" awiri):

Kupanga kwa SSAW (mpaka 60" awiri):
Kutsegula → Kuwongola → Cholumikizira cha Coil → Kuwongola → Kugaya M'mphepete →Kupereka → Kukonzekera-kupindika → Kupanga → Kuwotcherera → Kudula Plasma → Kuwotcherera Tab → Kuwotcherera Mkati & Kunja Kwakakulu → Kuchotsa Tab→ Kuwotcherera Pitirizani → Kupera Koperani → Mayeso → Mayeso Odziimira Kukulitsa→ Kuyesa kwa Hydrostatic → End Facing/Bevelling → Base Metal & Weld Ultrasonic Testing→X-ray & Film Examination → Final Inspection→ Weight & Dimension→ Coating→Marking

Ubwino wa Pamwamba:Mapaipi a ERW amawonetsa kutsirizika kwapamwamba poyerekeza ndi mitundu ya SAW chifukwa cha njira yowotcherera yosalala komanso kuchepetsedwa kulimbitsa ma weld.
Zolakwika:Zowonongeka za ERW nthawi zambiri zimakhala zozungulira ndipo zimawonekera mosavuta kudzera mu kuyendera kwa akupanga, pomwe mapaipi a SAW amatha kuwonetsa zolakwika za volumetric kuchokera ku ma depositi otuluka.
Residual Stress:Kupanga kwa ERW kumapangitsa kuti pakhale kupsinjika kotsalira kocheperako kudzera mumayendedwe oyendetsedwa ndi ma saizi.
Kukhalitsa:Mapaipi a ERW amatha kukonzedwa bwino - zowotcherera zimatha kukonzedwanso, pomwe kukonza zolakwika za SAW kungayambitse ngozi yong'aluka kapena dzimbiri.

Ubwino wa Chitoliro Chopanda Msoko:

• Kufufuza kwakukulu kwa kukula kwake
• Kusinthasintha kwapang'ono pamagawo angapo
• Makonda kutalika kuthekera
• Zida zogwirizana ndi NACE MR 0175 zilipo
• Madongosolo otumizira zinthu mwachangu
• Kuthekera kwakukulu m'mimba mwake kudzera pakukulitsa kotentha (mpaka 40")
• Complete zinthu traceability ndi khalidwe chitsimikizo

Ubwino wa Chitoliro cha Welded:

• Mtengo-zothetsera zazikulu zakuya
• Njira zingapo zamakono zowotcherera
• Kuthekera kokulirapo kosiyanasiyana
• Kulondola kofanana kwa dimensional
• Kukonzekera bwino kwa kupanga

Mapulogalamu Oyambirira:

• Njira zotumizira mapaipi amafuta
• Maukonde ogawa gasi
• Njira zosonkhanitsira malo opangira mafuta
• Njira yoyeretsera mapaipi
• Kulumikizana kwa nsanja za Offshore
• Mapaipi oyendera mayendedwe

Mafotokozedwe a API 5L Line Pipe amatsimikizira kugwira ntchito modalirika pamapaipi oyendera m'mafakitale onse amafuta ndi gasi, akukwaniritsa miyezo yapadziko lonse lapansi ya PSL1 ndi PSL2.

Zogulitsa zonse zimayesedwa mozama kuphatikiza:

• Kusanthula kwa mankhwala
• Kutsimikizira katundu wamakina
• Non-mayeso owononga (NDT)
• Kuyeza kuthamanga kwa Hydrostatic
• Akupanga kuyendera
• X-kuunika kwa ray (mipopi yowotcherera)
• Dimensional kutsimikizira

Mafotokozedwe Aukadaulo akuyenera kutsimikiziridwa panthawi yoyitanitsa. Lumikizanani ndi gulu lathu la mainjiniya kuti mumve zofunikira pakugwiritsa ntchito komanso zolemba zambiri zaukadaulo.
