Ibisobanuro ku bicuruzwa
ASTM A53 nigisobanuro gisanzwe cyumuyoboro wicyuma cya karubone mubunini bwumuyoboro wa nominal, ugamije kugeza amazi, gaze, umwuka, umwuka hamwe nuburyo rusange bukoreshwa mubukanishi. Irimo umuyoboro udafite ikizinga, umuyoboro wa ERW weld hamwe nitanura - umuyoboro usudira, muburyo bubiri (Icyiciro A na Grade B).
Umuyoboro wa Octal utanga ASTM A53 Icyiciro A na Grade B hamwe na galvanizing itabishaka, kurangiza gutandukanye, hamwe nicyemezo cyuzuye cyo gutanga imishinga.
Ubwoko bwibicuruzwa
- Andika S - Nta kinyabupfura
Ashyushye - yarangije cyangwa ikonje - yarangije umuyoboro udafite kashe. Bikunzwe kuri sisitemu yo kotsa igitutu, ibikorwa byinganda nibikorwa bya mashini aho bisabwa guhuza urukuta.
- Ubwoko E - ERW (Amashanyarazi - Kurwanya Welded)
Umuyoboro muremure usudira hamwe nubushyuhe bwo gusudira - ufatwa nkuko bisabwa nibisobanuro. Igiciro - guhitamo neza kumurongo wamazi, sisitemu yumuriro hamwe nuburyo bukoreshwa.
- Andika F - Itanura - Butt Welded
Iraboneka Icyiciro A gusa. Byakoreshejwe kumurongo - serivisi yumurimo aho ibisobanuro byemerera iki gikorwa.
- Impamyabumenyi
Icyiciro A:imbaraga zisanzwe muri serivisi rusange
Icyiciro B:hejuru cyane kandi itanga imbaraga, mubisanzwe byerekanwe kubitutu no gukoresha imashini
Ibigize imiti
| Ikintu | Icyiciro A (max%) | Icyiciro B (max%) | Imikorere |
|---|---|---|---|
| Carbone (C) | 0.25 | 0.30 | Imbaraga, zigenzurwa no gusudira |
| Manganese (Mn) | 0.95 | 1.20 | Gukomera, ubuziranenge |
| Fosifore (P) | 0.05 | 0.05 | Kugabanya ubukana |
| Amazi (S) | 0.045 | 0.045 | Igenzurwa no gukomera / imashini |
| Umuringa (Cu) * | 0.40 | 0.40 | Kurwanya ruswa |
| Nickel (Ni) * | 0.40 | 0.40 | Komeza imbaraga |
| Chromium (Cr) * | 0.40 | 0.40 | Kuramba hejuru |
| Molybdenum (Mo) * | 0.15 | 0.15 | Kugumana ubukana |

Ibikoresho bya mashini
| Umutungo | Icyiciro A. | Icyiciro B. | Inyandiko |
|---|---|---|---|
| Imbaraga zingana | Biruta cyangwa bingana na 330 MPa (48 ksi) | Biruta cyangwa bingana na 415 MPa (60 ksi) | Muri rusange imbaraga z'umuyoboro |
| Tanga imbaraga | Kurenza cyangwa bingana na 205 MPa (30 ksi) | Biruta cyangwa bingana na MPa 240 (35 ksi) | Ubushobozi bwumuvuduko |
| Kurambura | Kurenza cyangwa bingana na 30% | Kurenza cyangwa bingana na 30% | Bikwiranye nuudodo, kunama, guhimba |
Icyiciro B, hamwe nuburemere bukabije kandi butanga agaciro, nuburyo busanzwe bwo guhitamo imirongo yumuriro, sisitemu yumuriro na serivisi yubukanishi.
Gukora & Igenzura
ASTM A53 yemerera inzira zombi zidafite icyerekezo. Imiyoboro idafite ubushyuhe irashyushye - ikora kandi nini kugeza kuri OD isabwa hamwe nubunini bwurukuta. Imiyoboro ya ERW igomba kuba ifite amajwi, ikomeza gusudira; agace kegereye ni ubushyuhe - bivurwa iyo byerekanwe kugirango martensite itageragejwe idahari. Itanura - buto yo gusudira umuyoboro ugarukira mu cyiciro cya A.
Uburebure bwa buri muyoboro bukorerwa:
- ubugenzuzi bugaragara kandi buringaniye kubugororotse, OD, urukuta n'ubuso
- ikizamini cya hydrostatikecyangwabyemewe ntabwo - ikizamini cyangiza
- kugoreka / gusibanganya ibizamini byo gusudira kugirango hemezwe ubuziranenge
Uru rwego rwo kugenzura rutuma A53 yemerwa mumazi, gaze na serivisi zubatswe mumazu, ibimera nibikorwa rusange.
Ibipimo & Tolerances
| Parameter | Ibisobanuro |
|---|---|
| Ingano ya Nominal | 1/8 muri - 26 muri (DN 6 - DN 650) |
| Uburebure bw'urukuta | ICYIGISHO CYA 10 - SCH XXS (harimo ibisanzwe, 40, 80, 160) |
| Uburebure | 5-12 m (SRL / DRL) cyangwa gukata - kugeza - uburebure |
| Ubworoherane bwa OD | mubisanzwe ± 1% kuri NPS 2 nini |
| Kwihanganira Urukuta | mubisanzwe ± 12.5% |
| Kurangiza | byoroshye, bishushanyije, bifatanye cyangwa bifatanye hamwe |
Bishyushye - Shira Amahitamo
Imiyoboro ya ASTM A53 irashobora gutangwa ashyushye - kwibiza hamwe no kwibizwa. Zinc igomba guhura na ASTM B6, kandi misa yo gutwikira ntishobora kuba munsi yagaciro kavuzwe muri ASTM A53. Igipfundikizo kigomba guhoraho, kitarangwamo ibibara byambaye ubusa, ibisebe hamwe ningoma ziremereye.
Galvanized A53 irasabwa kumurongo wo hanze, serivisi zamazi nikirere, kurinda umuriro kugaragara, hamwe nibidukikije bisaba kunoza ruswa. Umuyoboro wa Octal urashobora gutanga imiyoboro yumukara na galvanised kuva murwego rumwe, hamwe no kugenzura.
Ibisanzwe
- Amazi, gaze hamwe na compression - imirongo yikirere mumazu, ibimera na sisitemu ya komini
- Hasi - kotsa igitutu na serivisi za kondensate
- Umuriro - kurinda no kumena imiyoboro (aho ASTM A53 yemerewe na sisitemu)
- Abagize imiterere nubukanishi bakoresheje umuyoboro nkinkingi, gutondeka cyangwa amakadiri
- Serivise rusange yimiyoboro hamwe nugukoresha insinga / imiyoboro aho API 5L idakenewe
Gutanga & Icyemezo - Umuyoboro wa Octal
- ASTM A53 Ubwoko S / Ubwoko E / Ubwoko F.
- Icyiciro A na B.
- Umukara, irangi cyangwa ishyushye - kwibiza kurangiza
- Ibibaya, byegereye, bifatanye cyangwa bifatanye
- Hydrostatike / NDE igerageza kuri buri burebure
- EN 10204 3.1 Icyemezo cyo gupima urusyo hamwe nibisubizo bya chimique na mashini
- Kohereza hanze - bundles ziteguye hamwe nimpera - kurinda cap no gushiraho ikimenyetso neza
