API 5L Payipu etaliiko musonyi

API 5L Seamless Steel Pipes-Tekinologiya ow'omulembe mu kukola payipu

Octal Pipe ekola eby’okugonjoola ebizibu bya API 5L Line Pipe ebijjuvu, nga bizingiramu payipu z’ekyuma ezitaliiko buzibu n’eza welded ezikoleddwa mu nkola z’okutambuza amafuta g’amafuta ne ggaasi ow’obutonde. Obusobozi bwaffe obw’okufulumya bukwata ku ddaala okuva ku API 5L Gr B okutuuka ku X80, esangibwa mu mitendera gyombi egy’okulaga PSL1 ne PSL2. Payipu zino zikoleddwa yinginiya okukozesebwa okukozesebwa ku lukalu/ku nnyanja n’embeera z’obuweereza obukaawa (embeera za H2S ezikosa nga zigoberera NACE).
API 5L Line Pipe eweereza amakolero g’amafuta ne ggaasi n’ebigonjoola ebinywevu eby’okugonjoola payipu ebikoleddwa ku mbeera ez’enjawulo ez’emirimu. Enzimba y’ekyuma kya kaboni egoberera ebisaanyizo bya API SPEC 5L, okukakasa nti ekola eyeesigika mu mbeera z’ebbugumu erisukkiridde, embeera ezivunda, n’okukozesa empeereza enkaawa ezirimu H2S.

Payipu ya Layini y'Ekyuma Etaliiko Musonno
Ekolebwa okuyita mu nkola ezikubiddwa mu bbugumu-ezizingiddwa nga tezirina musonno n’ezikubiddwa mu ngeri ennyogovu (ezizingiddwa), ezisangibwa mu buwanvu obutuuka ku yinsi 40. Okuzimba okutaliimu buzibu kumalawo obuzibu bw’omusono gwa weld, okuwa obulungi bw’enzimba obw’ekika ekya waggulu ku nkola za puleesa eya waggulu-.
Welded Ekyuma Layini Payipu
Ekoleddwa nga ekozesa tekinologiya ow’omulembe ow’okuweta omuli enkola za ERW (Electric Resistance Welding), LSAW (Longitudinally Submerged Arc Welding), ne SSAW (Spirally Submerged Arc Welding), nga ziwa eby’okugonjoola ebizibu ebigula ssente-okukozesebwa mu puleesa eya mutindo.

Ebyetaago by’Ensengekera y’Eddagala

Welded pipe chemical composition ekuuma stricter control parameters bw’ogeraageranya n’enjawulo seamless, okukakasa consistent ebintu eby’obugagga mu nkola yonna ey’okukola. Ebirimu kaboni, manganese, phosphorus, ne sulphur bifugibwa bulungi okutuukana n’ebiragiro bya API 5L.

Eby’obugagga by’omulimu gw’ebyuma

Ebiragiro by’amaanyi g’amakungula n’amaanyi g’okusika bisigala nga bikwatagana wakati w’enjawulo ezitaliiko musonno n’eziweta mu ddaala eryenkanankana. Ebintu by’ebyuma bikakasibwa okuyita mu nkola z’okugezesa ezijjuvu okukakasa nti zigoberera ebisaanyizo bya API 5L.

Okugumiikiriza kwa Diameter ey’ebweru:
omu. Diameters < 60.3mm (23⁄5"): Okugumiikiriza omubiri gwa payipu ±0.5mm, Enkomerero ya payipu ±0.5mm; Okugumiikiriza okwetooloola 0.9mm (omubiri), 0.6mm (enkomerero)b. Diameters 60.3mm okutuuka ku 610mm: Okugumira omubiri ±0.0075D, Okugumiikiriza enkomerero ±0.005D (ekisinga obunene ±1.6mm);
Ebigumiikiriza mu buwanvu bwa bbugwe:

Enkola z'okukola payipu ezitaliiko buzibu
Enkola ya Hot-Rolled Seamless Enkola:

Enkola ya Cold Drawn/Rolled:Okuteekateeka payipu ya maama → Okukebera → Okusiiga → Okujjanjaba ku nkomerero → Okusiika → Okusena → Okufuumuula → Okukuba ebifaananyi/okuzingulula mu nnyonta → Okwoza n’okuggyamu amasavu → Okulongoosa mu bbugumu → Okugolola → Okugezesa amazzi → Okussaako obubonero n’okusiiga langi → Okutereka

Enkola z’okukola payipu ezikoleddwa mu welded
ERW Manufacturing ( Entono oba yenkana 24" diameter):

LSAW/JCOE Okukola (20 "-40" obuwanvu):

SSAW Okukola (okutuuka ku 60" diameter):
Okusumulula → Okugolola → Okusiba koyilo → Okugolola → Okusiba ku mbiriizi →Tutuusa → Nga tekunnabaawo-okubeebalama → Okukola → Okuweta tack →Okusala pulasima → Okuweta tab → Okuweta munda & ebweru Submerged Arc Welding →Okuggyawo tab→ Okusenya kwa weld → Automatic UT→ X{1}}Okugezesa emisinde→ Okugezesa ku nkomerero ya payipu→Hydrostatic Test →End Facing/Bevelling → Base Metal & Weld Ultrasonic Testing→X-ray & Film Okukebera → Okukebera okusembayo→ Obuzito & Ekipimo→ Okusiiga→Okussaako obubonero

Omutindo gw’okungulu:Payipu za ERW ziraga okumaliriza okw’okungulu okw’ekika ekya waggulu bw’ogeraageranya n’enjawulo za SAW olw’enkola y’okuweta enyangu n’okukendeeza ku kunyweza okuweta.
Ebifaananyi by’obulema:Ebikyamu bya ERW bitera okuba eby’ennyiriri era nga byangu okuzuulibwa okuyita mu kwekebejja okw’amaloboozi amangi, ate payipu za SAW ziyinza okwoleka obulema mu bunene okuva mu bifo ebiterekeddwamu amazzi.
Stress Esigaddewo:Okukola ERW kivaamu okunyigirizibwa okusigaddewo okutono okuyita mu nkola ezifugibwa ez’okukyusakyusa n’okugerageranya obunene.
Obuwangaazi:Payipu za ERW ziwa okuddaabiriza okwongezeddwa - obulema mu welding busobola okuddamu okukolebwa, so nga okuddaabiriza obulema bwa SAW kuyinza okuleeta obulabe bw’okukutuka oba okukulukuta.

Emigaso gya Payipu Etaliiko Musono:

• Ebintu ebingi eby’obunene obw’omutindo
• Okukyukakyuka mu bungi obutono mu bipimo ebingi
• Obusobozi bw’obuwanvu obukoleddwa ku mutindo
• Ebikozesebwa ebikwatagana ne NACE MR 0175 biriwo
• Enteekateeka z’okutuusa ebintu mu bwangu

• Okuyungibwa ku pulatifomu ku nnyanja
• Ebikozesebwa mu ntambula ya payipu

Ebiragiro bya API 5L Line Pipe bikakasa omulimu ogwesigika mu nkola z’entambula ya payipu mu makolero gonna agakola amafuta ne ggaasi, nga bituukana n’omutindo gw’ensi yonna ku mitendera gyombi egy’okulaga ebintu bya PSL1 ne PSL2.

Ebintu byonna bikeberebwa mu bujjuvu omuli:

• Okwekenenya ebirungo by’eddagala
• Okukakasa eby’obugagga by’ebyuma
• Okugezesebwa okutali-okuzikiriza (NDT) .
