ASTM A672 Ingano Urwego
Ingano isabwa ingana: DN≥400mm [16 muri] na WT≤75mm [3 muri].
Kubindi bipimo byumuyoboro, mugihe byujuje ibindi bisabwa byose muribi bisobanuro, birashobora no gukoreshwa.
Kwirinda
Ikidodo kigomba gusudwa kabiri, cyuzuye-cyinjira.
Gusudira bigomba gukorwa haba mu ntoki cyangwa mu buryo bwikora hakoreshejwe amashanyarazi arimo gushira ibyuma byuzuza.
Weld irashobora kugenzurwa hakoreshejwe radiografiya kandi igomba gukurikiza ibivugwa mu gice cya VII UW-51 cya ASME Boiler na Code Vessel Code.
Uburebure bwa weld ntibushobora kurenza mm 3 [1/8 muri].
Kuvura Ubushuhe
Ibyiciro byose usibye 10, 11, 12, na13 bigomba gushyukwa mu ziko rigenzurwa na ± 25 ° F [± 15 ° C]:

Nyuma, kuzimya mumazi cyangwa amavuta.Nyuma yo kuzimya, umuyoboro ugomba gushyukwa kugeza ku bushyuhe buke bwo hasi bwerekanwa mu mbonerahamwe ya 2 kandi bugakomeza.
ubushyuhe byibuze 0.5 h / santimetero [0.2 h / cm] z'ubugari cyangwa 0.5 h, ubwo aribwo bunini, kandi bukonje.
Ibigize imiti
Inshingano yuwabikoze agomba gusuzuma imiterere yimiti yisahani hamwe nudusudira kugirango yubahirize ibisabwa byerekana isahani kubikoresho byateganijwe hamwe nuburyo bwo gusudira bwo kubitsa icyuma gisudira.
Ikizamini
Inshuro zigeragezwa: icyitegererezo kimwe kuri tombora.
Uburyo bwo Kwipimisha: Ibigereranyo bizakorwa hakurikijwe QW-150 mu gice cya IX cya ASME Boiler na Code Vessel Code.Ibigereranyo bizageragezwa ku bushyuhe bwicyumba hakurikijwe uburyo bwikizamini nubusobanuro A370.
Usibye icyiciro cya Dxx, Hxx, Jxx, na Nxx mu cyiciro cya 3x, 4x, na 5x transvers tensile ya plaque shingiro, bizagenwa ku ngero zaciwe ziva mu muyoboro ukoreshwa n'ubushyuhe.
Ibisabwa kubisubizo.
Guhindura-Kuyobora-Weld-Bend Ibizamini
Umubare w'ibizamini: Inshuro zigeragezwa: rimwe kuri buri cyiciro, ingero ebyiri
Uburyo bw'igerageza: Ibizamini bisabwa muburyo bwikizamini nubusobanuro A370, igika A2.5.1.7 bizuzuzwa.
Kubyimbye byurukuta hejuru3/ 8muri. [mm 10] ariko munsi ya3/4muri.
Ku bunini bw'urukuta3/4muri. [19 mm] no hejuru yingero zombi zigomba gukorerwa ikizamini cyo kuruhande.
Ibisabwa kubisubizo: Ikizamini cyunamye kigomba kwemerwa niba ntakibazo cyangwa izindi nenge zirenze1/8muri.
Ibice bituruka kumpera yikigereranyo mugihe cyo kugerageza, kandi biri munsi1/4muri. [6 mm] zapimwe mu cyerekezo icyo aricyo cyose ntizisuzumwa.
Ikizamini cy'ingutu
Ibyiciro bya X2 na X3 bigomba gupimwa hakurikijwe A530 / A530M, Ibisabwa bya Hydrostatike.
Ikizamini cya Radiyo
Uburebure bwuzuye bwa buri weld yo mu cyiciro cya X1 na X2 bigomba gusuzumwa ku buryo bwa radiyo hakurikijwe kandi byujuje ibisabwa na ASME Boiler na Pressure Vessel Code, Igice cya VIII, paragarafu ya UW-51.
Isuzuma rya radiografi rishobora gukorwa mbere yo kuvura ubushyuhe.
Kwihanganira ibipimo kuri ASTM A672
| Imikino | Agaciro ko kwihanganira | Icyitonderwa |
| Hanze ya Diameter | ± 0.5% | Ukurikije ibipimo bizenguruka |
| Hanze-Yuzuye | 1%. | Itandukaniro hagati yingenzi na ntoya hanze ya diameter |
| Guhuza | 1/8 muri. [3 mm] | Ukoresheje metero 10 z'ubugari bushyizwe ku buryo impande zombi zihura n'umuyoboro |

Kugaragara kwa ASTM A672
Umuyoboro urangiye ugomba kuba udafite inenge kandi ugomba kurangizwa nakazi.
Ibisabwa kimwe no mubisobanuro ASTM A20 / A20M yo kurangiza hejuru yicyuma.
Inenge no Gusana
Kwiyemeza neza
Igipimo cya ASTM A672 ntigaragaza urwego rwemewe rw inenge hamwe nigipimo cyo kugena imiyoboro kandi mubisanzwe bivuga ibipimo byubwubatsi nibikorwa byinganda.
Inenge zimbere: Inenge zimbere zishobora kuba zirimo porosity, slag, inclusitions, nibindi.
Inenge zo hanze: Inenge zo hanze zishobora kubamo ibice, amenyo, gushushanya, nibindi.
Gukuraho no Kwisubiraho
Ubusembwa bwubuso burashobora gukurwaho no gukabya cyangwa gutunganya hamwe nubunini busigaye bwa mm 0.3 munsi yubugari busanzwe.
Kwiheba kwa regrind bigomba guhuzwa kimwe mubidukikije.
Gusana gusudira
Inenge igomba gukurwaho nuburyo bukwiye bwo gukata cyangwa gukanika cyangwa gushushanya hanyuma bigategurwa gusana imyenge yasudutse.
na radiologue yasuzumwe hakurikijwe ASME Boiler na Pressure Vessel Code, Igice cya VIII, paragarafu UW-51.
Uburebure bwuzuye bwumuyoboro wasanwe bugomba gutunganywa nubushyuhe nyuma yo gusanwa hakurikijwe ibisabwa byateganijwe.
ASTM A672 Ikimenyetso
Ikimenyetso ni gikubiyemo ibi bikurikira:
Ibiranga uwabikoze, nk'ikirango cyangwa ikirango.
Ibisobanuro byumuyoboro (ubunini, uburebure bwurukuta, nibindi).
Urwego rwibikoresho cyangwa ubwoko bwumuyoboro.Urugero: C60-22 (mu magambo ahinnye y'icyiciro: C60 n'icyiciro cya 22).
Igipimo cyo gukora umuyoboro ni ASTM A672.
Itariki yumusaruro cyangwa nimero yumusaruro.
Gukoresha ASTM A672 Umuyoboro wibyuma
Mu nganda z’amashanyarazi, ASTM A672 Umuyoboro w’amashanyarazi Welded Steel umuyoboro ukunze gukoreshwa mugutanga amavuta muri sisitemu yo guteka.
Mu nganda z’imiti, umuyoboro w’icyuma ASTM A672 usanzwe ukoreshwa mu gutwara imiti itandukanye, aside, n’ibisubizo bya alkali, n’ibindi bitangazamakuru.
Mu nganda za peteroli na gaze, umuyoboro w’icyuma ASTM A672 usanzwe ukoreshwa mu gutwara peteroli, gaze gasanzwe, n’andi mazi cyangwa gaze.
Turi abanyabugeni bo mu rwego rwo hejuru basudira ibyuma bya karuboni kandi bitanga ibicuruzwa biva mu Bushinwa, kandi tunabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
