ASTM A335 P5 Umuyoboro w'icuma udafise umugozi

ASTM A335 Grade P5 ni umuyoboro w’icuma gikozwe mu cuma c’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma. Kubera ko chromium iri hagati ya 4–6% na molybdenum iri hagati ya 0.45–0.65%, P5 itanga uruvange rw’ingirakamaro rwo guhangana n’uguhinduka kw’ibinyabuzima, inkomezi zo gukwegakwega, n’ubushobozi bwo gusudira. Ivyo bituma ari amahitamwo meza ku mirongo y’amaboteri n’ay’umwotsi, amatiyo y’ibikoresho vy’ugushushanya, imirongo y’ibikoresho vy’uguhindura n’ivy’ubuhinga bushushe aho ivyuma vy’umuyagankuba vyokwihuta cane canke bikabura inkomezi. Iyo ishikirijwe mu buryo busanzwe kandi buteye akaga, P5 iguma ishikamye mu bijanye n’ingero be n’ukwizigirwa kw’ubuhinga mu bihe birebire vy’ibikorwa.

Iyi nzira y’ivyuma iri hasi ya P22/P91, rero biroroshe gusudira no gutera PWHT, ariko iratanga uburyo bwiza bwo gucungera oxidation kuruta ivyicaro biri hasi-Cr.

Ivyo bipimo bihuye n'ivyo gutanga bisanzwe-na-bisabwa na ASTM A335.

P5 itegerezwa gukorwa no gukoreshwa neza n’ubushuhe-kugira ngo ishobore gukora igihe kirekire-ku bushuhe. Octal Pipe ikoresha inzira idafise umurongo itangura ku bipande vy’ama Cr-Mo bisukuye. Ivyuma bishushwa bigatoborwa kugira ngo bibe imyobo, hanyuma bishushe-bizungurutswa canke bikakonja-bikwegwa ku rugero rw’inyuma n’uburebure bw’uruhome vyategekanijwe. Inyuma yo guhingura, imiyoboro irasanzwe ku rugero rwa 900–950 kugira ngo itunganye ivyuma vy’ivyuma, ifungure ama carbides atari -ahuye kandi ikureho imibabaro. Intambwe ikurikira yo gushaza ku 675–750 degrees igarura uburemere kandi igashiraho umubumbe ushikamye w’ivya ferrite–carbide. Iyi nzira y’ubushuhe y’inzira zibiri-ni yo iha P5 ubushobozi bwo guhangana n’ugukwegakwega n’ugushikama kw’imitsi mu bikorwa.

Inyuma yo gukoresha ubushuhe, umuyoboro wose urageragezwa n’amazi, ugasuzumwa mu buryo bw’ingero n’isuzuma ritagiramwo -ugusambura (umuyagankuba w’amajwi canke w’umuyagankuba nk’uko vyategetswe). Amatiyo atangwa mu buryo busanzwe kandi bufise ubushuhe bushitse (EN 10204 3.1 canke 3.2), ivyo bikaba ari ngirakamaro ku migambi y’amashanyarazi n’iy’isuku.

Iyi nzira ipfutse imirongo y'umwotsi iri hagati-n'imitwe minini y'ibikorwa vy'isuku/ivy'imiti.

Ku bushuhe bwo gukoresha bushika nko kuri degre 565 (degre 1050 F), P5 ikora oxide y’ubutunzi bw’ivyuma vyitwa chromium-igabanya ububabare n’ugutakaza ivyuma. Kubera ko molibdène ikomeza ivyuma vy’ivyuma, uguhinduka kw’ivyuma bigenda buhoro kuruta uko bigenda mu vyuma vy’ivyuma vy’ivyuma. Ivyo bikoresho bifasha kandi kunanira uguhinduka kw’ubushuhe be n’ugusenyuka kw’imbere, ku buryo ubushuhe buva ku ruhande n’uburemere bw’uruhome biguma bishobora kumenyekana mu bihe vy’isuzuma. Ku bikorwa bisaba ubushuhe bwinshi canke umubabaro mwinshi, abahinga bashobora kwimukira kuri P11 canke P22, ariko ku bikorwa vy’ubushuhe buhambaye, buringaniye-, P5 ni yo akenshi ihitamwo ryiza.

Inguvu n'uburyo bw'amaboteri: imirongo y'umwotsi, imitwe y'amaboteri, ibikoresho vy'ubushuhe bwinshi n'ibikoresho vy'ubushuhe busubira mu rwego rw'ubushuhe buringaniye

Ivyumba vyo gusukura n'ivy'ubuhinga bwa peteroli: ifuru n'imiyoboro y'abahindura, imirongo y'ugutanga ubushuhe, imitwe y'umuriro n'imfashanyo

Ibikoresho vy'imiti n'ifumbire: ubushuhe bwinshi -ibikoresho bihindura ubushuhe, ibikoresho n'ibikoresho vyinshi

Ivyumba vy'amavuta na gazi: gutera umwotsi n'imirongo y'ugukora ishushe aho umuyoboro wa Cr-Mo ugaragara

Kugereranya n'amanota asanzwe ya Cr-Mo

Ivyo bifasha abahinga mu vy’imigambi guhitamwo ivyuma bibereye igihe hariho ivyicaro vyinshi vya ASTM A335 vyemewe.

Octal Pipe ikora ivyigwa bihuye n’ibisabwa vya ASTM A335 na ASTM A999. Ivyo birimwo igerageza ry’amazi, NDT y’umubiri w’imiyoboro n’iherezo ryayo, igenzura ry’uburemere n’uburemere, n’igerageza ry’ugusaza/ugusha kugira ngo bemeze uburemere bw’imiyoboro. Igerageza ry’ingaruka canke ry’amaradiyo rishobora kwongerwako igihe ivyerekeye umugambi bisaba ko haba umugwi w’abagenzuzi wo hejuru. Ivyavuye mu bipimo vyose bishirwa mu ncamake mu vyemezo vy’ibipimo vy’insyo kandi imiyoboro irashirwako ikimenyetso kugira ngo imenyekane neza.

Itanga umuyoboro w'ukuri ASTM/ASME A335 P5 udafise umurongo mu mimerere isanzwe kandi ikomeye

Inyandiko z'ingero zishitse, z'ubuhinga n'iza NDT zibereye imigambi y'amashanyarazi, ivy'ugusukura n'ivy'imiti

Gusohora hanze-biteguye gupakira, gukingira no gushirako ikimenyetso

Ubushobozi bwo gutanga amanota ari hafi (P11, P22) ku mirongo y’amazi n’ibikoresho vy’amazi bifise uturere dutandukanye tw’ubushuhe

Ibirimwo n'ibisobanuro vyanditswe mu gicuruzwa-mbere, uburyo bw'ubuhinga bubereye gusohora urubuga no gushaka

IBIBAZO bibazwa

 

 

IKIBAZO CA 1: Ni igiki ASTM A335 P5 umuyoboro ukoreshwa?

A1:Ivyuma vy’ivyuma bitagira umurongo vy’ubushuhe bwinshi, umuvuduko munini mu mahinguriro y’isuku, amahinguriro y’amashanyarazi, n’ibice vy’ibikorwa.

Ikibazo ca 2: "5Cr-0.5Mo" bisobanura iki ku muyoboro wa P5?

A2:Ni umubumbe w'ivyuma bitera imbere ubushobozi bwo guhangana n'ivyuma bitera umuriro n'ubukomezi bw'ubushuhe burengeye -.

IKIBAZO CA 3: Ni igiki gikoreshwa mu gusudira -kingana na ASTM A335 P5?

A3:ASTM A691 5CR ni ikintu gisanzwe kigaragazwa ku muyoboro w’ivyuma vy’agaciro -moly ukozwe mu gipande gihuye.

Ikibazo ca 4: Nohitamwo gute P5 vs P9 vs P11 vs P22?

A4:Hitamwo hakurikijwe ubushuhe bwo gukoresha, uburemere bw’uguhinduka kw’umubiri, n’umugambi spec-P5 akenshi utorwa igihe Cr nyinshi ikenewe kugira ngo umuntu ashobore gukora neza.
