ASTM A252 ni iki?

ASTM A252 ni igipimo cyateguwe cyane cyane kugirango gikoreshwe hamwe nicyuma kirunda ibyuma.

ASTM A252 ikoreshwa mubirundo byumuyoboro aho silinderi yicyuma ikora nkumunyamuryango uhoraho utwara imizigo, cyangwa nkigikonoshwa kugirango ikore ibirundo bya beto.

Icyiciro cya 2 nicyiciro cya 3 ni bibiri muribi byiciro.

ASTM A252 / A252M -2019

ASTM A252 Icyiciro

A252 igabanijwemo ibyiciro bitatu hamwe nuburyo bukurikiranye bwimashini.

Bari: Icyiciro cya 1, Icyiciro cya 2, naIcyiciro cya 3.

Icyiciro cya 2 nicyiciro cya 3 nicyiciro gikunze gukoreshwa muri ASTM A252, kandi turasobanura imiterere yibyiciro byombi muburyo bukurikira.

Uburyo bwo Gukora

ASTM A252Irashobora gukorwa nuburyo budasubirwaho, gusudira birwanya, gusudira flash, cyangwa uburyo bwo gusudira fusion.

Mubikoresho biringaniye, ibyuma bitagira ibyuma bitanga ubufasha buhebuje bitewe nimbaraga zabo nyinshi hamwe nimbaraga ziranga imbaraga.

Byongeye kandi, ibyuma bitagira ibyuma birashobora gukorwa hamwe nuburebure bwurukuta rwinshi, bubafasha kwihanganira imihangayiko myinshi, bikarushaho kongera ubwizerwe mubikorwa byubufasha.

Nyamara, imiyoboro yicyuma idafite icyerekezo irashobora kubyara kugeza kuri diameter ntarengwa ya mm 660, igabanya imikoreshereze yabyo isaba ibirundo binini bya diameter.Muri uru rubanza,LSAW(Longitudinal Submerged Arc Welded) naSSAW(Spiral Submerged Arc Welded) imiyoboro y'ibyuma nibyiza cyane.

Ibigize imiti ya ASTM A252 Icyiciro cya 2 nicyiciro cya 3

Ibirimo fosifore ntibirenza 0.050%.

Nta bindi bintu bisabwa.

ASTM A252 Icyiciro cya 2 nicyiciro cya 3 Ibikoresho bya mashini

Imbaraga za Tensile nimbaraga zo gutanga cyangwa gutanga umusaruro

	Icyiciro cya 2	Icyiciro cya 3
Imbaraga zingana, min	60000 psi[415 MPa]	60000 psi[415 MPa]
Gutanga umusaruro cyangwa gutanga imbaraga, min	35000 psi[240 MPa]	45000 psi[310 MPa]

Kurambura

Ibisobanuro birambuye murashobora kubisanga muriASTM A252 Umuyoboro wuzuye.

Ubworoherane

Urutonde	Sort	Umwanya
Ibiro	Uburemere bw'imyumvire	95% - 125%
Hanze ya Diameter	Kugaragara Hanze ya Diameter	± 1%
Uburebure bw'urukuta	Kugaragaza uburebure bw'urukuta	min 87.5%

Uburebure

Uburebure bumwe	16 kugeza 25 ft [4.88 kugeza 7,62 m], santimetero
Uburebure bubiri	hejuru ya metero 25 na 7,62 m hamwe byibuze byibuze metero 35
Uburebure bumwe	uburebure nkuko byasobanuwe hamwe no gutandukana byemewe ± 1 muri.

Ibipimo bijyanye

ASTM A370: Uburyo bwikizamini nubusobanuro bwo gupima imashini yibicuruzwa byibyuma;

ASTM A751: Uburyo bwo Kwipimisha, Imyitozo, na Terminologiya yo gusesengura imiti yibicuruzwa byuma;

ASTM A941: Amagambo ajyanye nicyuma, ibyuma bitagira umuyonga, Amavuta afitanye isano, na Ferroalloys;

ASTM E29: Imyitozo yo gukoresha imibare yingenzi mumibare yikizamini kugirango umenye imikorere hamwe nibisobanuro;

Ibyerekeye Twebwe

Botop Steel nicyiza cyo mu rwego rwohejuru cyogosha ibyuma bya karubone ikora kandi ikanatanga ibicuruzwa biva mubushinwa, kandi ikanabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
