ASTM A53 ERWumuyoboro w'icyuma niAndika E.mubisobanuro bya A53, byakozwe na gahunda yo gusudira yo kurwanya, kandi iraboneka mubyiciro byombi A na Grade B.
Irakenewe cyane cyane mubukanishi nigitutu kandi ikoreshwa kandi nkintego rusange yo kugeza amavuta, amazi, gaze, numwuka.
Ibyiza bya ERW umuyoboro wibyuma, nkaigiciro gitonaumusaruro mwinshi, kora ibikoresho byo guhitamo mubikorwa byinshi byinganda.
Botop Steelni ubuziranenge bwo mu rwego rwo hejuru bwo gusudira ibyuma bya karuboni ikora kandi ikanatanga ibicuruzwa biva mu Bushinwa, kandi ikanabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
Ibarura ryacu rirahunitse neza kandi turashobora guhaza ibyifuzo byabakiriya bacu byihuse kubintu byinshi nubunini.
ASTM A53 / A53M ikubiyemo ubwoko n'amanota akurikira:
Andika E.: Amashanyarazi-arwanya-gusudira, Icyiciro A na B.
Andika S.: Nta kinyabupfura, Icyiciro A na B.
Andika F.: Itanura-butt-gusudira, gukomeza gusudira Icyiciro A na B.
Andika E.naAndika S.ni bibiri bikoreshwa cyane.Ibinyuranye,Andika F.ni Byakoreshejwe Kuri Utubuto duto twa diameter.Kubera iterambere mu buhanga bwo gusudira, ubu buryo bwo gukora bukoreshwa gake.
Diameter: DN 6 - 650 [NPS 1/8 - 26];
Diameter yo hanze: 10.3 - 660 mm [0.405 - 26 muri.];
Ubunini bwurukuta hamwe nicyuma cyerekana uburemere:
Imiyoboro ya Flat-end irashobora kuboneka mu mbonerahamwe X2.2;
Imiyoboro ifatanye kandi ihujwe irashobora kuboneka mu mbonerahamwe X2.3.
ASTM A53 iremerera kandi gutanga imiyoboro hamwe nibindi bipimo mugihe umuyoboro wujuje ibindi bisabwa byose.
ERWikoreshwa cyane mugukora uruziga, kare, hamwe nurukiramende rwa karubone hamwe nu miyoboro mito mito.
Ibikurikira bikurikira nuburyo bwo kubyara umusarurokuzenguruka umuyoboro wa ERW:
a) Gutegura ibikoresho: Ibikoresho byambere mubisanzwe ni ibyuma bishyushye bishyushye.Izi ngofero zabanje gutondekwa no gukemurwa mubugari bukenewe.
b) Gushiraho: Buhoro buhoro, binyuze murukurikirane rw'imizingo, umurongo ugizwe muburyo buzengurutse uruziga.Muri iki gikorwa, impande zumurongo zegeranijwe buhoro buhoro hamwe mugutegura gusudira.
c) Gusudira: Nyuma yo gukora imiterere ya tubular, impande zumurongo wibyuma zishyutswe no kurwanya amashanyarazi muri zone yo gusudira.Umuyoboro mwinshi cyane unyuzwa mubikoresho, kandi ubushyuhe butangwa nuburwanya bukoreshwa mugushyushya impande kugera aho zishonga, hanyuma bikazunguruka hamwe nigitutu.
d) Gutanga: Nyuma yo gusudira, burrs yo gusudira (ibyuma birenze urugero byo gusudira) bivanwa imbere no hanze yumuyoboro kugirango harebwe neza neza imbere mu muyoboro.
e) Ingano n'uburebure.Imiyoboro noneho iracibwa kugirango uburebure bwateganijwe.
f) Kugenzura no kugerageza: Umuyoboro wibyuma uzakorerwa igeragezwa nubugenzuzi bukomeye, harimo gupima ultrasonic, gupima hydrostatike, nibindi, kugirango ubuziranenge bwumuyoboro wibyuma bujuje ubuziranenge nibisobanuro.
g) Kuvura hejuru: Hanyuma, umuyoboro wibyuma urashobora gukorerwa ubundi buryo bwo kuvura nko gushyushya ibishishwa bishyushye, gushushanya, cyangwa ubundi buryo bwo kuvura hejuru kugirango hirindwe ruswa hamwe nuburanga.
Weld mu bwoko bwa E cyangwa Ubwoko F Urwego B.umuyoboro ugomba kuvurwa nubushyuhe cyangwa ukundi kuvurwa nyuma yo gusudira kugirango martensite itageragejwe idahari.
Ubushyuhe bwo kuvura ubushyuhe bugomba nibura1000 ° F [540 ° C].
Iyo umuyoboro ukonje wagutse, kwaguka ntigushobora kurenga1.5%ya diametre yagaragaye hanze ya pipe.
