Ivyerekeye gukoresha imiyoboro y'icuma: Kuva ku nkengera y'ikiyaga gushika ku gufumbira

Ivyerekeye ugukoresha – Umuyoboro w'umunani

Kuva ku bikoresho vy’amazi maremare gushika ku mirongo y’amazi yo mu karere ka Arctique, imirongo y’amazi y’ibisagara bininibinini gushika ku mirongo y’amazi y’ubugaragwa, amatongo manini manini gushika ku bibanza vyo kujabuka amashamba y’imvura - Octal Pipe itanga umugongo w’icuma ukora cane -ku bijanye n’inguvu, amazi n’ibikorwa remezo vyo kw’isi yose.

Wohereze ikibazo ubu

Amavuta na Gazi yo mu kiyaga

Ivyuma vy’amazi maremare, FPSO topsides n’amajakete adahinduka bisaba amatiyo ashobora kurokoka inyigisho y’imipfunda idahinduka, umunyu n’imikazo irenga 15.000 psi. Igikoresho kinini-ca LSAW X65–X70 gifise 3LPE canke FBE + igipfukisho c’uburemere bwa beton ni co kigereranyo c’inganda hano. Amahuza y’imbere (VAM TOP, TENARIS BLUE) atuma gazi-ikora neza mu mirongo y’amazi n’iyo yohereza hanze iva ku kiyaga c’Uburaruko ija muri Brezil imbere y’-imirima y’umunyu.

Imirongo y'amazi yo munsi y'ikiyaga n'Ibohe-Imigongo

Ku burebure burenze 2.500 m, SSAW X60–X70 ifise 5-layer sintered epoxy canke insulation itose itanga uburinganire bwiza bw’igiciro, uguhinduka n’uburinzi bw’ugusenyuka. Igishushanyo c’umurongo w’uruzitiro gitanga umubabaro wo gupfukama mu buryo buringaniye mu gihe co gushiramwo uruzitiro-lay canke J-lay, mu gihe uburebure bwa CWC bwa 50–120 mm butanga icemezo co gushikama ku rwego rwo hasi mu migende ikomeye.

Ku butaka -Ugutangaza urugendo rurerure

Imirongo y’amavuta y’ibitoro, ibicuruzwa n’ibidukikije -ishingiye kuri API 5L X52–X80 LSAW kugira ngo igere ku bilometero amajana n’amajana n’ibibanza bikeyi vy’amapompa. 3ivyuma vy’amapompa n’uburinzi bwa katode bitanga 50+ ubuzima bw’umwaka mu bugaragwa, mu mirima no mu butaka buhoraho. Ukwihanganira OD gukomeye n’ibipimo vy’umwimbu vyinshi-bituma uruhome ruguma rufise uburebure - rero uburemere n’igiciro - biguma ari bike.

Ibishanga, ibishanga n'amashamba y'imvura

Ivu ryoroshe kandi rishobora guterera cane mu turere nk’Ikiyaga ca Amazone, Niger Delta, na Louisiana bayous bisaba ko hashirwako uburemere buremereye bwa beton (CWC) ku miyoboro ya SSAW canke LSAW kugira ngo haboneke ubushobozi bwo guterera nabi no gukingira guterera mu gihe c’umwuzure w’ibihe. Inkuta zikomeye cane zifatanijwe n’ivyuma bifatanye n’ibindi bihimba vy’umubiri (FBE) canke 3LPE zirashobora kunanira neza H2S, CO2, n’ibindi bihimba vy’umubiri bikunda gusangwa mu bidukikije vy’ibitoke.

Amazi n'imigende y'amazi yo mu bisagara

Munsi y’ibarabara ry’igisagara,AWWA C200 imiyoboro y'umugozikandiAmatiyo ya ASTM A53 ERWni vyo bihitamwo neza ku bijanye n’amazi yo kunywa, ibizingiti vyo gukingira umuriro, n’amazi y’inguvu y’amazi mabi.

Imbere mu gihugusimenti-ivu ry'ivucankeivyokurya-ivyo gupfuka epoxyyubahiriza bimwe bishitseNSF/ANSI 61ku bijanye n'umutekano w'amazi yo kunywa-, mu gihe hanzepoliyuretani, polyethylene isohotse, cankeanti-umugozi wo gukingira uburoziitanga uburinzi bw’igihe kirekire-ku butaka bwo mu bisagara bukomeye cane, amazi yo mu butaka, n’ugusenyuka kw’amazi agendagenda-kunze kuboneka mu bisagara bininibinini.

Gufumbira mu misozi no mu buhinzi

Ivyuma binini-vy’imbere n’ivyo gutonyanga bikoresha SSAW (12–48 in) ikozwe mu gitereko canke polyethylene- kugira ngo bigende amamiliyoni y’amagaloni ku musi ata n’imwe ivuza. Uburemere buke kuri metero n’uburebure bw’uburebure bwa metero 12–18 bigabanya igihe co gufatanya n’ugushiraho mu butaka bwo murima bufunguye.
