ASTM A53 Giredhi B (inozivikanwawo seASTM A Giredhi B 53kanaA53 GrB) ichiri imwe yemhando dzemapaipi esimbi yekabhoni anozivikanwa zvikuru pasi rose. Inoshandiswa zvakanyanya mu kutapurirana kwemvura, mafuta negasi, mapaipi ekuvaka, masisitimu emakanika, uye mapaipi ebhoyira.
Asi kana mapurojekiti epasi rose akasanganisa mwero, vatengi vanobvunza kuti:
"Chii chinonziASTM A53zvinhu zvakafanana mu EN, DIN kana JIS?
Gwaro iri rinowedzera kuenzanisa, rinounza mamakisi akaenzana esimbi, rinotsanangura mutsauko wekuyedza, uye rinokubatsira kuongorora kuchinjana paunenge uchitenga.ASTM A53 pombi yesimbi, pombi isina musono, kana zvimwe zvinotsiva.
Kunzwisisa ASTM A53 Giredhi B: Hunhu Hukuru
Mavharo eASTM A53/A53Mpombi yesimbi isina musono (Rudzi S)uyeERW welded pombi(Rudzi E)nechinangwa chakajairika.
✔ Simba reASTM A53 Giredhi B riri pakati nepakati, rinowanzo shandiswa mukutakura mvura uye mabasa ekutakura kumanikidzwa.
Mhando dzeMakemikari (ASTM A53 Gr B):
Kabhoni ≤ 0.30%
Manganese ≤ 1.20%
Fosforasi ≤ 0.05%
Sarufa ≤ 0.045%
Zvimiro zveMichina:
Simba reKusimba ≥415 MPa
Simba reGoho ≥240 MPa

Zvinhu zvakafanana zveASTM A53 GrB mu EN, DIN & JIS
Magiredhi aya anoenderana zvakanyanya nezvinhu zvakafanana zveASTM A53 maererano nesimba, kuumbwa kwekabhoni uye hunhu hwekureba.
Sei Vachidaro?Zvinoenzaniswa?
EN P235GH→ Kugohorera: ~235 MPa, Kusimba: 360–500 MPa — zvakafanana neASTM A53 Giredhi B.
JIS STPG410→ Mwero wekabhoni wakafanana uye kureba — zvakanakira kushandiswa kunoda kuramba kumanikidzwa uye kugona kusundirwa.
Saka, zvinhu izvi zvinogona kutariswa seASTM A53 GrB, kunyanya mumapaipi ebhoyira, ekuvaka uye epressure.
ASTM A53 vs ASTM A106 vs API 5L — Kuvhiringidzika Kwakajairika Kwevatengi
Mainjiniya mazhinji epasi rose haangotsvage chete"A53 GrB yakaenzana"asi bvunzawo kuti:
✔ "Ko ASTM A106 yakaenzana neASTM A53 here?"
✔ "API 5L yakaenzana neA53 GrB here?"
Mhinduro: kwete chaizvo.
Saka chiile ASTM A106 Grade B uyeAPI 5L Gr B anowanzo taurwa, varidzimwe sarudzo, kwete zvakaenzana zvakanyanya.
Kusiyana Kwekugadzira Kune Basa
Kunyangwe kana zvinhu zvakaenzana zveASTM A53 zvichienzaniswa nemakemikari, mitemo yekuongorora inosiyana:

Nzira yekusimbisa Kuenzana Pamwe Chete?
✔ Enzanisa kukosha kwemakemikari nemakemikari (±5% kushivirira kunogamuchirika)
✔ Kumbira zvitupa zveMTC kana EN/DIN/JIS
✔ Kuongorora kwevamwe (senge SGS / BV / TÜV) kuti vaone kana zvinhu zvanyatsoenderana nezvinodiwa
Maitiro aya anoderedza njodzi pakusarudzaASTM A53 zvinhu zvakaenzanayemapurojekiti epasi rose.
SeiYUANTAI DERUNMutengesi weASTM A53 Akavimbika
Iine ruzivo rwemakore anopfuura makumi maviri mukugadzira, YUNTAI DERUN inopa:
✔ ASTM A53 ERW pombi yesimbi
✔ ASTM A53 GrB pombi isina musono
✔ EN / DIN / JIS mapaipi esimbi yekabhoni yakaenzana negiredhi
Tinovimbisa kuti:
Chitupa Chekuyedza Chigayo
Kuyedzwa kwemakemikari, zvemakanika, zvehydrostatic, uye zve ultrasonic
Chitupa Chakajairika
Kunyangwe vatengi vakatsanangura zvinhu zvakafanana neASTM A53, ASTM A106, API 5L, kana A53 GrB, YUANTAI DERUN inopa mhinduro dzinoenderana nesevhisi yakanakisisa.
Pfungwa Dzekupedzisira
Kunzwisisa zviyero zvakaenzana zveASTM A53 Grade B kwakakosha pakutenga kwenyika dzese.
Kunzwisisa kuti pombi yesimbi yeASTM A53 ERW inoenzaniswa sei neEuropean P235GH kana Japanese STPG410 kunobatsira vatengi:
✔ kudzivirira zvikanganiso zvemagadzirirwo
✔ kuderedza kunonoka kwezvitupa
✔ kuchengetedza uye kutevedzera mitemo
