ASTM A537 Icyiciro 1,2,3 Icyuma nicyuma cyicyuma

Ibisobanuro bya ASTM A537 ni Ibipimo ngenderwaho byerekana ibyombo bya Vessel, Ubushyuhe-bushyushye, Carbone-Manganese-Silicon Steel ikoreshwa mugukoresha imiyoboro ya fusion yasuditswe hamwe nubwubatsi. Porogaramu zisanzwe ni imiyoboro yingutu yagenewe serivisi ziciriritse nubushyuhe bwo hasi busaba ubukana buhebuje kimwe nububiko bwa API 650 na API 620. Icyiciro cya 1 ibikoresho birahari nkuko bisanzwe kandi Icyiciro cya 2 kirahari nka Quenched & Tempered plaque.

Inyandiko

Ibipimo bya ASTM:

A20 / A20M: Ibisobanuro kubisabwa muri rusange kubisahani byamazi
A435 / A435: Kubisuzuma-Byibone Ultrasonic Ikizamini cya plaque
A577 / A577M: Kubizamini bya Ultrasonic Angle-Beam Ikizamini cya plaque
A578 / A558

Inyandiko zo gukora:

Isahani yicyuma munsi ya ASTM A537 Icyiciro cya 1, 2 na 3 igomba kwicwa ibyuma kandi ikubahiriza ingano nziza ya austenitike isabwa muri A20 / A20M.

Uburyo bwo kuvura ubushyuhe:

Isahani yose munsi ya ASTM A537 igomba gufatwa nkubukurikira:
Isahani ya ASTM A537 Icyiciro cya 1 igomba kuba isanzwe.
Icyapa cya 2 nicyiciro cya 3 bigomba kuzimwa no gutwarwa. Ubushyuhe bwubushyuhe bwicyapa cya 2 ntibugomba kuba munsi ya 1100 ° F [595 ° C] kandi ntiburi munsi ya 1150 ° F [620 ° C] kumasahani yo mucyiciro cya 3.
