ASTM A179 (ASME SA179.
ASTM A179 na ASME SA179 ni amahame abiri ahwanye rwose.Kugirango byorohe, ASTM A179 ikoreshwa hepfo.
ASTM A179 ibereye imiyoboro yicyuma ifite diameter yo hanze ya 1/8 ″ - 3 ″ [3.2mm - 76.2mm].
Botop Steelni ububiko bwibyuma bidafite icyuma biva mubushinwa, biguha amahitamo manini yo mu rwego rwohejuru ASTM A179 / ASME SA179 imiyoboro ikonje ikonje ikonje.
Twiyemeje guha abakiriya bacu ibicuruzwa na serivisi byujuje ubuziranenge kugirango imishinga yawe igende neza.Hitamo Botop Steel, hanyuma uhitemo umufatanyabikorwa wizewe.
Tumaze kuvuga ko A179 ikorwa hifashishijwe uburyo bwo gukora ubukonje bukonje.Ni ubuhe buryo bwihariye bugira uruhare mubikorwa byo gukonjesha bikonje?Nyamuneka reba imbonerahamwe ikurikira.
Mubisanzwe ASTM,A556ikoresha kandi uburyo bukonje bukonjesha uburyo bwo gukora ariko bugenewe cyane cyane ubushyuhe bwamazi.Ababyifuza barashobora kumenya byinshi.
Nyuma yo gushushanya ubukonje bwa nyuma, imiyoboro yicyuma itunganywa nubushyuhe bwa 1200 ° F [650 ° C] cyangwa irenga.

ASTM A179 ntabwo yemerera kongeramo ibindi bintu mubigize imiti.
Ubukomezi bwicyuma ntigomba kurenga 72 HRBW (Gukomera kwa Rockwell).

Buri muyoboro ugomba gukorerwa igitutu cya hydraulic cyangwa, mugihe umuguzi abiteganya, hashobora gukoreshwa ikizamini cyamashanyarazi kidasenya.
Umuyoboro wibyuma ukomeza umuvuduko byibuze 5s udatemba.
Umuvuduko wikizamini ubarwa ukoresheje formula ikurikira:
Inch - Ibice bya Pound: P = 32000 t / D.
SI Ibice: P = 220.6t / D.
P = igitutu cya hydrostatike, psi cyangwa MPa;
t = uburebure bwurukuta rwerekanwe, muri. cyangwa mm;
D = yerekanwe hanze ya diameter, muri. Cyangwa mm.
Ibikurikira nububiko busanzwe bwa A179, kandi gupakira byabugenewe nabyo birashobora gutangwa ukurikije ibisabwa byumushinga.
Umuyoboro wuzuye, umwenda wirabura (wabigenewe);
6 "no munsi yubunini Muri bundles hamwe na pamba ebyiri, ubundi bunini bworoshye;
Byombi birangirana nabashinzwe kurinda;
Impera y'ibibaya, impera ya bevel;
Ikimenyetso.
