Gusobanukirwa ASTM A139: Inyuma yumuyoboro wa COIDH na Porogaramu ya Spiral

Mw'isi yaka, code n'amahame agenga ibikoresho byakoreshejwe ni ngombwa kugira ngo umutekano urebye umutekano, kuragirana n'imikorere. Kimwe muri ibyo bipimo niASTM A139, igira uruhare runini mugukora no gushyira mu bikorwa ikiramu (arc yasukuye ubusa) imiyoboro isusurutsa. Muri iyi blog, tuzaganira ku kamaro ka ASTM A139, ibiranga umuyoboro wa SAMESH, kandi nibyiza gusudira gusudira mu nganda.

ASTM A139 ni iki?

ASTM A139 nicyo kisobanuro cyateguwe na societe yabanyamerika cyo kugerageza nibikoresho (ASTM) byerekana ibisabwa kuri electrofusion (arc) umuyoboro usuye. Ibipimo bikoreshwa cyane cyane kumiyoboro ikoreshwa mugutwara amazi na gaze. Ibisobanuro bikubiyemo amanota menshi yicyuma kandi byemeza ko imiyoboro yatangaga ryujuje imiterere yihariye hamwe nibigize imiti.

ASTM A139 Ibipimo nibyingenzi byababikora nabashakashatsi kuko bitanga ubuyobozi kumikorere, harimo no kwerekana uburyo bwo gusudira hamwe ningamba zo kugenzura ubuziranenge bugomba gufatwa. Mugukurikiza aya mahame, abakora barashobora kwemeza ko ibicuruzwa byabo byizewe kandi bikwiranye nibisabwa bitandukanye, bivuye kuri peteroli na gaze kugirango twubake.

Uruhare rw'umuyoboro wa Vach

Umuyoboro cyangwa spiral arc gusudira ni ubwoko bwumuyoboro usuye usukuye uragasumba imirongo ihindagurika muburyo bwa silindrike. Ubu buryo bwo gutanga umusaruro butuma hashyirwaho imiyoboro minini ya diameter byombi bikomeye kandi byoroheje. Ikoranabuhanga ryo muri spiral ryakoreshejwe muriUmuyoboro itanga ibyiza byinshi, harimo:

1. Kugenda neza:Igikorwa cyumusaruro wa sachh gikunze ubukungu kuruta uburyo gakondo, bigatuma habaho imishinga ishimishije kumishinga minini.

2. Verietuelity:Umuyoboro wa Vachsh urashobora gukorerwa muburyo butandukanye nubunini, bigatuma bikwiranye nuburyo butandukanye, harimo ibikoresho byamazi, sisitemu yamazi, nibikoresho byubaka.

3. Imbaraga zongerewe:Kubakwa gusunika gasutswe bitanga imbaraga no kurwanya igitutu cyo hanze, bigatuma hach ​​pipe nziza kubidukikije.

Ibyiza byo gusudira gusudira

Umuyoboro ususurutsa urubuga nubundi bwoko bwumuyoboro usutswe ukoresheje tekinoroji yo gusunika. Uburyo bukubiyemo gupfunyika ibyuma bikikije mandrel no gusudira muburyo bukomeza.Umuyoboro wa Helical itanga ibyiza byinshi, harimo:

1.Ubuso bwimbere bwimbere bwumuyoboro ususurutsa imivurungano no kuzamura amazi, bigatuma habaho gusaba inganda za peteroli na gaze.

2. Uburemere bwagabanutse:Igishushanyo mbonera cyemerera inkuta zinanutse zitubahiriza imbaraga, zituma urumuri rworoshye kandi rworoshye gukora no gutwara.

3. Uburebure bubi:Umuyoboro usukuye watanzwe urashobora gukorwa murebure igihe kirekire, kugabanya umubare wingingo zisabwa mumuyoboro no kugabanya ibishoboka byo kumeneka.

Mu gusoza

Muri make, ASTM A139 ni urugero rwingenzi rwo gukora umuyoboro wa sadh hamwe numuyoboro ususurutsa usukuye, kureba ko ibi bice byingenzi bihura numutekano nkenerwa. Umuyoboro wihariye wa POIPH na pipe isusurutsa ibara rituma bitagereranywa munganda ziva mu kubaka n'ingufu. Mugihe ikoranabuhanga rikomeje gutera imbere, akamaro ko gukurikiza amahame yashizweho nka ASTM A139 bizakura gusa kugirango habeho ibikorwa remezo bikomeza umutekano kandi neza. Waba ufite injeniyeri, rwiyemezamirimo, cyangwa umuyobozi wumushinga, usobanukirwe aya mahame kandi ibyiza byubwoko bwubwoko bwimiyoboro nibyingenzi kugirango dufate ibyemezo byuzuye kumishinga yawe.
