Ajụjụ Ndị A Na-ajụkarị:

Q: Gịnị mere ị ga-eji họrọ X60 karịa X52 maka ọkpọkọ gas?
A: X60 na-enye ike mmepụta dị elu nke 15% (415 MPa vs 360 MPa), na-enye ohere maka mgbidi dị gịrịgịrị (nke na-abụkarị mbelata 10-15%) maka otu ọkwa nrụgide ahụ. Nke a na-ebelata ibu na ọnụ ahịa ihe, ọkachasị maka paịpụ ndị dị anya. Agbanyeghị, X60 chọrọ usoro ịgbado ọkụ siri ike ma na-enwe mmetụta karịa na mgbawa hydrogen. Maka nrụgide dị n'okpuru 10 MPa, X52 na-adịkarị ọnụ ala karịa. Maka nrụgide karịrị 12 MPa, a na-atụ aro X60 ma ọ bụ X65.

Ajụjụ: Kedu ihe dị iche n'etiti X60 PSL1 na PSL2?
A: PSL2 nwere oke kemịkalụ siri ike (karịsịa obere C, P, S), nnwale mmetụta Charpy dị mkpa (27J @ 0°C ma ọ bụ obere), ike kachasị elu 90 HRB, ma chọọ 100% UT nke njikọta weld (PSL1 chọrọ naanị ntụpọ UT). Maka ahịrị ogwe gas na-arụ ọrụ na mpaghara ndị mmadụ bi ma ọ bụ obere okpomọkụ, a na-akọwapụta PSL2 mgbe mgbe.

A: Ị nwere ike inye X60 asambodo ọrụ dị ụtọ?
A: Ee. Anyị na-enye X60 PSL2 na nnwale HIC (NACE TM0284) na nnwale SSC (NACE TM0177). Nnabata nkịtị: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5% maka HIC. A na-etinye PWHT maka ọrụ mmiri niile X60 n'agbanyeghị ọkpụrụkpụ mgbidi iji hụ na ọ siri ike ≤ 85 HRB. Anyị enyela ọrụ mmiri X60 nye ọrụ Middle East na Southeast Asia.

Ajụjụ: Kedu nnwale mmetụta okpomọkụ dị ala ị nwere ike ime maka pipelines X60 arctic?
A: Anyị nwere ike ịnwale ruo -60°C. Paịpụ gas arctic nkịtị chọrọ mmetụta Charpy nke kacha nta 27J na -46°C. Womic na-enwetakarị 80-120J na -46°C. Maka njikwa mgbasa nke mgbawa, anyị na-emekwa DWTT na -20°C yana mpaghara ịkpụcha kacha nta 85%. Biko kọwaa okpomọkụ na ike nnwale achọrọ.

A: Kedu usoro kacha mma maka pipeline X60 nke dị n'èzí - JCOE ma ọ bụ UOE?
A: A na-ahọrọ UOE maka mmiri dị n'èzí n'ihi na ọ na-emepụta gburugburu ka mma (±0.2% vs ±0.5% maka JCOE) yana obere nrụgide fọdụrụnụ. Nke a dị oke mkpa maka iguzogide nrụgide hydrostatic mpụga (mda) yana maka ịgbado ọkụ ubi a pụrụ ịdabere na ya na arịa ndị a na-etinye n'ime ala. UOE na-enyekwa arụmọrụ ike ọgwụgwụ ka mma maka ndị na-arị elu na-agbanwe agbanwe. Maka mmiri dị omimi (<100m) n'akụkụ mmiri dị nso, a na-anabata JCOE.

Q: Kedu oge ndu nkịtị maka ọkpọkọ X60 LSAW?
A: Oge ndu ọkọlọtọ maka X60 PSL1: ụbọchị 35-50. Maka X60 PSL2 yana nnwale ọrụ sour na PWHT: ụbọchị 50-70. Iwu ọsọ ọsọ (ụbọchị 25-35) enwere ike maka obere ọnụọgụ (< tọn 1,000) ma ọ bụrụ na efere dị na ngwaahịa. Maka iwu buru ibu (> tọn 20,000), oge ndu nwere ike ịgbatị ruo ụbọchị 90.

A: Ị na-enyocha paịpụ X60 LSAW nke ndị ọzọ?
A: Ee. Anyị na-arụ ọrụ na SGS, BV, TÜV, DNV, ABS, na LR. Enwere ike inyocha ya n'ụlọ ọrụ mmepụta ihe anyị n'oge mmepụta, onye nnọchi anya onye ahịa ahụ hụrụ ya. Anyị na-enye asambodo EN 10204 Ụdị 3.2 mgbe a rịọrọ ya.

Ihe Ịma Aka na Ngwọta Teknụzụ:

●Nrubeisi ọrụ siri ike maka gas nwere akara H₂S– Gas sitere n'okike nwere 5-10 ppm H₂S na okpomọkụ ọrụ 55°C. Womic mere nnwale HIC na SSC na mpaghara mmepụta 12. Ha niile gafere na CLR 0%, CTR 0%, CSR 0% maka HIC. Nnwale SSC (NACE TM0177, 720h) egosighi mgbawa elu. Anyị rụzuru nke a site n'ịnọgide na-enwe CEV ≤ 0.38%, itinye PWHT maka paịpụ WT 19.0mm na 22.0mm niile (n'agbanyeghị API 5L anaghị achọ PWHT n'okpuru 25.4mm), na ijikwa ntinye okpomọkụ ịgbado ọkụ ruo ≤ 2.8 kJ/mm. Onye nyocha nke onye ahịa (BV) hụrụ nnwale niile ma kwado nsonaazụ ya.

●Ala ugwu nwere mgbagọ ogologo dị elu– Ụzọ ọkpọkọ ahụ gụnyere mkpọda ruo ogo 25. Ngbagọ ọkpọkọ X60 siri ike karịa ọkwa dị ala n'ihi ike dị elu. Womic nyere ọkpọkọ nwere njikọ otu ogologo (18m kama 12m ọkọlọtọ) iji belata ọnụọgụ nke mgbagọ ubi site na 33%.
