Ajụjụ Ndị A Na-ajụkarị:

A: Olee mgbe m ga-ahọrọ UOE kama JCOE maka X42?
A: UOE na-enye gburugburu ka mma (±0.2% vs ±0.5% maka JCOE) yana obere nrụgide fọdụrụnụ, na-eme ka ọ bụrụ ihe a na-ahọrọ maka pipelines mmiri miri emi (okpuru mmiri) na ọrụ mmiri ara ehi ebe nkwụsi ike nha n'okpuru nrụgide mpụga dị oke mkpa. JCOE na-arụ ọrụ dị ọnụ ala karịa maka ọtụtụ ọrụ n'akụkụ mmiri.

A: Ị nwere ike ime paịpụ mgbidi X42 dị arọ karịa 50mm?
A: Ee. Maka ọkpụrụkpụ mgbidi site na 50mm ruo 60mm, anyị na-eji otu efere a kpụrụ akpụ nke nwere PWHT. Maka 60–80mm, okpukpu abụọ nke ogologo oge. A na-ejikarị ha eme ihe maka eriri mmiri na 20–30 MPa ma ọ bụ maka penstoks hydroelectric.

Ajụjụ: Kedu ihe dị iche n'etiti PSL1 na PSL2 maka X42?
A: PSL2 nwere oke C, P, S siri ike karị, mmetụta Charpy dị mkpa (27J @ 0°C), ike kachasị elu 90 HRB, ma chọọ NDT karịa. Maka ahịrị nchịkọta gas nke nwere ike ịnwe obere okpomọkụ gburugburu ebe obibi ma ọ bụ akara H₂S, a na-atụ aro PSL2.

A: Ị na-enye ọrụ mmiri ara ehi X42?
A: Ee. Anyị na-enye X42 PSL2 yana ule HIC (NACE TM0284) na SSC (NACE TM0177). Ihe ndị a na-anabatakarị: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. Anyị enyela ọrụ X42 dị nro nye ọrụ Middle East na West Africa.

Ajụjụ: Kedu ka esi ejide n'aka na ọkpọkọ ndị dị arọ (40–60mm) na-arụ ọrụ nke ọma na ịgbado ọkụ?
A: Anyị na-eji igwe SAW nke nwere njikwa okpomọkụ kpọmkwem, nlekota okpomọkụ nke interpass, na UT akpaka 100% yana oge mgbasa ozi (TOFD) maka nyocha volumetric. A na-etinye PWHT iji belata nrụgide fọdụrụ.

Ngwa:A na-anakọta gas sitere n'oghere mmiri isii gaa n'ebe a na-ahazi ihe n'etiti ala apịtị Niger Delta. E jiri paịpụ mgbidi dị arọ nke dị sentimita iri atọ n'ogologo mee isi ihe na-agafe akụkụ apịtị nke dị kilomita 1.2, ebe paịpụ JCOE nke dị sentimita iri abụọ n'obosara bụ akara alaka.

Ihe Ịma Aka na Ngwọta Teknụzụ:

●Ngafe apịtị nwere paịpụ mgbidi dị arọ– A ga-etinye paịpụ 30″ × 19.0mm (ihe dị ka 355 kg/m2) n'elu apịtị nwere ụrọ dị nro nke ukwuu. Ụgbọ mmiri nkịtị enweghị ike ịbanye ebe ahụ. Womic Steel nyere paịpụ nwere njikọ otu ogologo (18m kama 12m2) iji belata ọnụọgụ nke njikọta ubi site na 33%, na-ebelata njikọta n'ebe ahụ n'ọnọdụ siri ike. Anyị nyekwara ndụmọdụ zuru ezu maka ibuli na ijikwa ya gụnyere oghere nkesa mgbasa.

●Nrubeisi ọrụ siri ike (H₂S dị ugbu a)– Gas ejikọtara ya nwere ruo 30 ppm H₂S. Womic mere nnwale HIC na ma paịpụ efere 20″ JCOE na 30″ a kpụrụ akpụ. Ihe nlele niile gafere na CLR 0%, CTR 0%, CSR 0%. Maka paịpụ 30″ (19mm WT), onye ahịa chọrọ ike dị n'okpuru 85 HRB (siri ike karịa API 5L's 90 HRB). Womic tinyere ọkụ induction mpaghara na seam weld iji hụ na ọ siri ike otu. Nsonaazụ: metal base 78–82 HRB, weld 80–85 HRB.

● Nrapado mkpuchi 3LPE na oke iru mmiri– Ntinye apịtị pụtara na a ga-emikpu paịpụ n'ime mmiri ruo ọtụtụ izu tupu e jupụta ya. 3LPE ọkọlọtọ nwere ike ịnweta mwepụ nke cathodic ma ọ bụrụ na anaghị achịkwa iru mmiri itinye ya. Womic tinyere mkpuchi ahụ n'ebe a na-arụ ọrụ na ihu igwe (kachasị 60% RH) ma mee nchọpụta ezumike 100% na 5kV. Ike ịkpụcha ahụ nke a nwalere na 25°C nyere ihe karịrị 200 N/cm, nke karịrị ihe achọrọ na ISO 21809 nke 100 N/cm.

●Lọjistik gaa ebe dị anya– E si Shanghai bufee paịpụ gaa Tin Can Island Port, Lagos, wee buru gwongworo gaa kilomita 380 gaa ebe Niger Delta dị. Ọnọdụ okporo ụzọ adịghị mma n'ihi oke ibu.

Onye ahịa ahụ kọrọ na enweghị ntụpọ njikọta n'oge njikọta girth ubi, nke a na-ekwu na ọ bụ n'ihi usoro bevel na njikwa ovality (≤ 0.3% maka paịpụ JCOE, ≤ 0.5% maka paịpụ efere a kpụrụ akpụ). Womic Steel ka edepụtara ugbu a dị ka onye na-eweta ngwaahịa akwadoro maka mgbasawanye paịpụ nke onye ahịa n'ọdịnihu.
