● Cikakken bin diddigin bayanai tare da bin diddigin RFID

Tambayoyin da Ake Yawan Yi:

T: Me yasa za a zaɓi X70 maimakon X65 don bututun iskar gas mai nisa?
A: X70 yana ba da ƙarfin samar da amfanin gona mafi girma da kashi 8% (485 vs 450 MPa), wanda ke ba da damar rage kauri daga bango na kimanin kashi 10-12% don irin wannan matsin lamba. Ga bututun mai nisan kilomita 1,000, wannan zai iya adana tan 50,000-80,000 na ƙarfe, wanda hakan ke rage farashin kayan aiki da kuma sawun carbon. Duk da haka, X70 yana buƙatar faranti TMCP masu tsada, sarrafa walda mai tsauri, da kuma ƙarin farashin dubawa. Matsakaicin wurin da ake keɓancewa yawanci yana kusa da kilomita 500-800. Ga gajerun bututun, X65 ya fi arha.

T: Shin X70 ya fi wahalar walda a filin fiye da X65?
A: Eh. X70 yana da mafi girman daidai da carbon (CEV 0.38-0.43% vs X65 0.35-0.40%) kuma yana da sauƙin kamuwa da fashewar hydrogen. Walda a fili yana buƙatar dumamawa kafin lokaci (yawanci 100-150°C don X70 da 75-100°C don X65) da kuma kula da zafin da aka shigar da zafi da kuma zafin interpass. Duk da haka, tare da ingantattun hanyoyin walda (WPS) da ƙwararrun masu walda, ana iya walda X70 cikin aminci. Womic tana ba da shawarwarin amfani da walda kuma tana iya samar da takardun shaida na cancanta.

T: Za a iya amfani da X70 don hidimar tsami (H₂S)?
A: Haka ne, amma yana buƙatar ƙarin ma'auni: CEV ≤ 0.38% (zai fi dacewa ≤ 0.36%), PWHT ga duk kauri na bango, tauri ≤ 85 HRB, HIC da gwajin SSC. Womic ta samar da sabis na tsami X70 ga ayyukan da ke da har zuwa 50 ppm H₂S. Lura cewa X70 ya fi saurin kamuwa da H₂S fiye da X65 ko X60, don haka masu aiki da yawa har yanzu suna fifita X65 don yanayin H₂S mai yawa.

T: Menene matsakaicin kauri na bango don bututun X70 LSAW?
A: JCOE/UOE matsakaicin 50.8mm, farantin da aka naɗe guda ɗaya har zuwa 70mm. Don kauri daga bango sama da 40mm, kayan aikin UOE suna da iyaka, kuma farantin da aka naɗe ya fi kyau. Kwanan nan mun samar da bututun CO₂ mai ƙarfi mai nauyin X70 914mm × 60mm WT (aikin CCS).

Tambaya: Wane gwajin taurin karyewa ake buƙata don X70?
A: API 5L yana buƙatar gwajin Charpy V-Notch (minti 27J) amma yawancin ayyukan suna ƙayyade ƙimar mafi girma (misali, 100J a -20°C). Ana buƙatar DWTT don sarrafa yaɗuwar karyewa (yankin yankewa ≥ 85% a zafin gwaji). Ga bututun ruwa na teku ko na arctic, ana ƙara gwajin CTOD (≥ 0.25mm a -20°C ko -46°C). Womic tana yin duk waɗannan gwaje-gwajen a cikin gida ko ta hanyar dakunan gwaje-gwaje na ɓangare na uku da aka amince da su.

T: Menene lokacin jagora na yau da kullun don bututun X70 LSAW?
A: X70 yana buƙatar faranti na TMCP waɗanda ke da tsawon lokacin jagora (makonni 8-12 daga injin niƙa). Jimlar lokacin jagora: kwanaki 70-100 daga oda zuwa jigilar FOB. Umarni na gaggawa (kwanaki 45-60) zai yiwu idan faranti suna cikin kaya.

T: Shin X70 yana buƙatar PWHT don sabis mara tsami?
A: API 5L ba ya tilasta wa PWHT yin amfani da bututun X70 ƙasa da 50.8mm WT. Duk da haka, masu aiki da yawa suna amfani da PWHT don bututun X70 ba tare da la'akari da kauri na bango ba don rage damuwa da kuma tabbatar da taurin HAZ. Womic na iya samar da PWHT idan an buƙata (ƙarin farashi da lokacin jagora).

Bayanin Aiki - Layin Gas na Gas na Gas na Tsakiyar Asiya Mai Nisa

Ƙasa:Iyakar Uzbekistan - Tajikistan - China (wani ɓangare na bututun iskar gas na Tsakiyar Asiya da China)
Daidaitacce & Matsayi:API 5L X70 PSL2 (ba mai tsami ba, amma tare da buƙatun ƙarancin zafin jiki)
Girma da Adadi:

● OD 1,219mm (48″) × WT 19.0mm – mita 85,000 (kimanin tan 48,500) wanda aka ƙera ta hanyar tsarin UOE

● OD 1,219mm (48″) × WT 22.2mm – mita 15,000 (kimanin tan 9,500) wanda tsarin UOE ya ƙera (bango mai kauri don ketare tsaunuka da yankunan kuskure)

● OD 1,016mm (40″) × WT 17.5mm – mita 40,000 (kimanin tan 17,800) wanda tsarin JCOE ya ƙera (layin reshe)
Jimilla:Mita 140,000 (kilomita 140), kimanin tan 75,800

Bayani dalla-dalla:Rufin 3LPE na waje (jimlar 3.0mm), ƙarshen da aka yanke 30°/1.6mm, gwajin hydro a 19.5 MPa (matsin lamba na ƙira 15.0 MPa). Tasirin Charpy da ake buƙata a -20°C (minti 80J, an cimma 150-220J) da kuma a -46°C (minti 50J, an cimma 100-160J). DWTT a -20°C: yankin yanke ≥ 85% ga jikin bututu, ≥ 70% don walda. Cikakken jiki UT (100% na girman bututu, ba kawai dinki ba). Dubawa na ɓangare na uku ta TÜV Rheinland a duk lokacin samarwa. DNV ta shaida gwajin hydrostatic akan 10% na samarwa.

Aikace-aikace:Fadada bututun iskar gas na Tsakiyar Asiya da China (Layi na D), jigilar iskar gas daga filayen iskar gas a Uzbekistan ta hanyar Tajikistan zuwa kan iyakar China. Jimillar tsawon wannan layin: kilomita 140. Bututun ya ratsa gindin tsaunukan Pamir, ciki har da yankuna huɗu masu aiki na girgizar ƙasa, manyan hanyoyin ketare koguna guda uku, da kuma canjin tsayi daga mita 400 zuwa mita 2,800.

Kalubalen Fasaha da Magani:

● Bambancin yanayi mai tsanani da kuma yanayin zafi– Tsawan bututun ya kama daga mita 400 zuwa mita 2,800, tare da yanayin zafi daga -35°C a lokacin hunturu zuwa +45°C a lokacin rani. Bututun 48" X70 suna buƙatar tauri mai ƙarancin zafi har zuwa -46°C (Charpy min 50J). An zaɓi faranti TMCP tare da ƙarin nickel (Ni ≤ 0.50%) don cimma tasirin Charpy a matsakaicin -46°C 120J. DWTT a yankin yankewa -20°C: 92-96% ga jikin bututu, 82-88% don walda. Duk gwaje-gwajen sun ci nasara.

● Ketare matsalar girgizar ƙasa - ƙira bisa ga matsin lamba– Sassan bututun mai guda huɗu sun haɗu da lahani masu aiki tare da yuwuwar ƙaura zuwa ƙasa har zuwa mita 1.5. An tsara bututun ta amfani da ƙira mai tushen matsin lamba (ba bisa ga matsin lamba ba). Wannan yana buƙatar bututun X70 tare da takamaiman rabon yawan amfanin ƙasa ≤ 0.85 (API 5L PSL2 yana ba da damar 0.93) da tsawaitawa iri ɗaya ≥ 15%. Womic ta samar da wani musamman "babban nau'in" X70 tare da rabon yawan amfanin ƙasa 0.80-0.84 da tsawaitawa iri ɗaya 16-18%. Mun kuma bayar da gwajin tensile na cikakken sashe (ba kawai tsiri ba) don tabbatar da ƙarfin matsin lamba.

● Ƙasa mai tsaunuka tare da buƙatun lanƙwasawa mai tsanani– Bututun ya ƙunshi kilomita 22 na bututun 48" da aka sanya a kan gangaren digiri 20-30. Lanƙwasa bututun X70 a cikin sanyi yana da iyaka (API 5L yana ba da damar 1.5° a kowace mita 12). An samar da bututun da ke da dogon haɗin gwiwa na mita 18 don sassan madaidaiciya da haɗin gwiwa na mita 12 don sassan lanƙwasa. Mun kuma yi gwajin lanƙwasa akan samfuran cikakken sikelin: an lanƙwasa bututun 48" × 19.0mm a cikin sanyi zuwa 2.0° a kowace mita 12 ba tare da fashewa ba (wanda UT da MT suka tabbatar bayan lanƙwasa).

● Matsewar kogi da ke buƙatar kauri mai yawa na bango– Magudanar ruwa guda uku (magudanar ruwa ta Oxus) suna buƙatar 22.2mm WT maimakon 19.0mm don ƙarin rugujewa da juriyar lanƙwasa yayin shigarwa. Womic ta yi amfani da tsarin UOE don waɗannan bututun don cimma ovality ≤ 0.2% (ainihin 0.12-0.18%), don tabbatar da santsi ta hanyar ramin. Bututun bango masu kauri suma suna buƙatar ƙarancin shigar zafi yayin walda (≤ 2.0 kJ/mm) don kiyaye ƙarfin HAZ.

● Tsarin jigilar kayayyaki na nesa a faɗin ƙasashe uku– An ƙera bututu a masana'antar Tianjin ta Womic, an jigilar su ta jirgin ƙasa zuwa Almaty (Kazakhstan), sannan aka mayar da su zuwa manyan motoci don isar da su ga wuraren gini a Uzbekistan da Tajikistan. Jimillar nisan da ake yi a sufuri: sama da kilomita 5,000. Womic ta yi amfani da motocin jirgin ƙasa na musamman tare da tallafi masu kauri da kuma manne na ƙarfe. An duba kowace bututu da RFID a kowane wurin canja wuri. Babu bututun da ya lalace yayin jigilar su duk da ketare iyaka guda 3 da kuma jigilar su sau 6.

● Bukatun rufewa masu tsauri don fallasa UV mai tsayi– A tsayin mita 2,800, hasken UV ya fi na teku girma da kashi 40%. Na'urar 3LPE ta yau da kullun na iya lalacewa a cikin babban UV. An yi amfani da 3LPE na womic tare da ingantaccen saman saman UV mai daidaita (baƙin carbon 2.5% idan aka kwatanta da na yau da kullun 2.0%). An yi amfani da murfin a gwajin yanayin UV mai sauri (awanni 1,000 QUV, riƙe sheƙi ≥ 80%). Ƙarfin barewa ya kasance > 200 N/cm bayan fallasa UV.

● Sakamako:An kammala tsawaita bututun mai tsawon kilomita 140 kuma an fara aiki da shi a kwata na biyu na shekarar 2025. Duk tan 75,800 na bututun X70 PSL2 sun wuce binciken TÜV ba tare da an yi watsi da su ba. Sassan ƙirar da aka yi bisa matsin lamba sun tsira daga girgizar ƙasa sau biyu (girman 4.2 da 5.1) a cikin watanni 18 na farko na aiki ba tare da wata alamar fashewa ko zubewa ba. Abokin ciniki (kamfanin iskar gas na ƙasa na Uzbekistan) ya yaba wa Womic Steel bisa "ingantaccen kula da inganci da tallafin fasaha." Womic yanzu ita ce mai samar da kayayyaki ga sassan Line D na gaba.
