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]:

Ibyiciro 20, 21, 22, na 23

Umuyoboro ugomba gushyukwa kimwe murwego rwoherejwe nyuma yubushyuhe bwo kuvura ubushyuhe bwerekanwe kumeza 2 byibuze byibuze 1 h / in.[0.4 h / cm] z'ubugari cyangwa kuri 1 h, iyo ari nini.

Ibyiciro 30, 31, 32, na 33

Umuyoboro ugomba gushyuha kimwe kugirango ubushyuhe bugabanuke kandi ntiburenze ubushyuhe busanzwe busanzwe bwerekanwa mu mbonerahamwe ya 2 hanyuma bigakonjeshwa mu kirere ku bushyuhe bw’icyumba.

Ibyiciro 40, 41, 42, na 43

Umuyoboro ugomba kuba usanzwe.

Umuyoboro ugomba gushyuha ubushyuhe bwubushyuhe bwerekanwe mu mbonerahamwe ya 2 nkibisanzwe kandi bigashyirwa ku bushyuhe bwa byibuze 0.5 h / muri. [0.2 h / cm] z'ubugari cyangwa kuri1/2h, icyaricyo cyose kinini, kandi gikonjesha ikirere.

Icyiciro cya 50, 51, 52, na 53

Umuyoboro ugomba gushyukwa kimwe nubushyuhe buri murwego rwo kugabanya ubukana kandi ntiburenze ubushyuhe bwo kuzimya bwerekanwe kumeza 2.

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.

ASTM A672 Ibipimo byo kuvura ubushyuhe

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
Umubyimba 0.01 muri. [0.3 mm] Uburebure bwurukuta ntarengwa munsi yubugari bwizina
Uburebure 0- + 0.5in [0- + 13mm] Impera zidasanzwe

 

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.

Gukoresha ASTM A672 Umuyoboro wibyuma
Gukoresha ASTM A672 Umuyoboro wibyuma

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!
