Ingano ya ASTM A106 na ASTM A53:
Ibisobanuro bya ASTM A53 bikubiyemo ubwoko bwo gukora imiyoboro yicyuma muburyo budasubirwaho kandi busudira, ibikoresho mubyuma bya karubone, ibyuma byirabura.Ubuso busanzwe, umukara, nubushyuhe-bushyushye bwa galvanised, zinc isize umuyoboro wibyuma.Diameter iri hagati ya NPS 1⁄8 kugeza NPS 26 (10.3mm kugeza 660mm), uburebure bwurukuta.
ASTM A106 ibisobanuro bisanzwe bikubiyemoCarbone idafite ibyuma, wasabye serivisi zubushyuhe bwo hejuru.
Ubwoko butandukanye hamwe n amanota kubisanzwe byombi:
Kuri ASTM A53 hari imiyoboro ya ERW hamwe nicyuma kitagira icyuma Ubwoko F, E, S butwikiriye Icyiciro A na B.
A53 Ubwoko bwa F, itanura ryibumba ryarasuditswe, rikomeza gusudira Icyiciro A.
A53 Ubwoko E, Kurwanya amashanyarazi gusudira (ERW), mu cyiciro cya A na B.
A53 Ubwoko S, Umuyoboro w'icyuma utagira ikizinga, mu cyiciro cya A na B.
Niba ibyuma bibisi byibyiciro bitandukanye murwego rwo gukomeza guta, ibisubizo byinzibacyuho bizamenyekana.Kandi uwabikoze agomba gukuraho ibikoresho byinzibacyuho hamwe nibikorwa bishobora gutandukanya amanota neza.
Mugihe ASTM A53 Icyiciro B mu muyoboro wa ERW (amashanyarazi arwanya amashanyarazi), icyuma gisudira kizakorwa hifashishijwe ubushyuhe byibuze 1000 ° F [540 ° C].Muri ubu buryo, nta martensite itageragejwe isigaye.
Mugihe umuyoboro wa ASTM A53 B mubukonje wagutse, noneho kwaguka ntigomba kurenga 1.5% ya OD isabwa.
Kuri ASTM A106 umuyoboro wibyuma, gukora Ubwoko gusa muburyo budasubirwaho, butunganya ubushyuhe bushyushye hamwe n'imbeho ikurura.Icyiciro muri A, B na C.
ASTM A106 Icyiciro A: Ikintu ntarengwa cya Carbone 0,25%, Mn 0.27-0.93%.Imbaraga ntarengwa 48000 Psi cyangwa 330 Mpa, gutanga imbaraga 30000 Psi cyangwa 205 Mpa.
A106 Icyiciro B: C ntarengwa C 0,30%, Mn 0.29-1.06%.Imbaraga ntarengwa 60000 Psi cyangwa 415 Mpa, gutanga imbaraga 35000 Psi cyangwa 240 Mpa.
Icyiciro C: Ntarengwa C 0.35%, Mn 0.29-1.06%.Imbaraga ntarengwa 70000 Psi cyangwa 485 Mpa, gutanga imbaraga 40000 Psi cyangwa 275 Mpa.
Bitandukanye naASTM A53 GR.B imiyoboro idafite ibyuma,ASTM A106 GR.B imiyoboro idafite ibyumaifite Si min 0.1%, A53 B ifite 0, A106 B rero irwanya ubushyuhe bwiza kuruta A53 B, kuva Si itezimbere ubushyuhe.
Ahantu ho gusaba byombi:
Imiyoboro yombi yakoreshejwe kuri sisitemu ya mashini nigitutu, gutwara amavuta, amazi, gaze, nibindi.
Porogaramu ya ASTM A53:
1. Kubaka, gutwara abantu munsi yubutaka, gukuramo amazi yubutaka mugihe wubaka, gutwara amazi meza nibindi.
2. Gutwara ibikoresho, gutunganya imashini.
3. Gukoresha amashanyarazi: Gukwirakwiza gaze, umuyoboro w'amazi utanga amazi.
4. Umuyaga w'amashanyarazi urwanya anti-static nibindi
5. Imiyoboro isaba zinc yashizwemo.
Porogaramu ya ASTM A106:
Cyane cyane kuri serivisi zubushyuhe bwo hejuru bugera kuri 750 ° F, kandi irashobora gusimbuza umuyoboro wa ASTM A53 muribenshi.Mu bihugu bimwe byibuze muri Reta zunzubumwe zamerika, mubisanzwe ASTM A53 ni iy'umuyoboro usudira mugihe ASTM A106 ari iy'imiyoboro y'icyuma idafite kashe.Niba kandi umukiriya yasabye ASTM A53 bazatanga na ASTM A106.Mu Bushinwa, uruganda ruzatanga umuyoboro wujuje ibipimo bitatu ASTM A53 GR.B / ASTM A106 GR.B /API 5L GR.B imiyoboro idafite ibyuma.
