ASTM A53 GR.B Mapaipi Azitsulo Opanda Msokonezo
Kufotokozera Kwachidule:
ASTM A53 ndi carbon steel alloy, ntchito ngati chitsulo structural kapena otsika-pressure plumbing.
ASTM A53 Standard ndi muyezo wamba kwa mapaipi mpweya zitsulo. Mpweya zitsulo chitoliro makamaka amatanthauza mpweya misa kagawo ndi zosakwana 2.11% popanda munali anawonjezera dala zinthu alloying zitsulo, ndi mlingo wa mpweya zili mu zitsulo kukhala chimodzi mwa zinthu zofunika kwambiri kukhala chikoka pa mphamvu yake ya chitsulo, kuuma kumawonjezeka, ndipo amachepetsa ductility, toughness ndi weld luso.Kupatula apo, nthawi zambiri imakhala ndi silicon, manganese, sulfure, phosphorous komanso kaboni.Poyerekeza ndi mitundu ina yazitsulo, ndiyo yoyamba, yotsika mtengo, yochuluka ya machitidwe, kuchuluka kwakukulu.Oyenera kukakamiza mwadzina PN ≤ 32.0MPa, kutentha -30-425 ℃ madzi, nthunzi, mpweya, haidrojeni, ammonia, nayitrogeni ndi mafuta a petroleum, ndi media zina.Chitoliro chachitsulo cha kaboni ndiye woyamba kugwiritsa ntchito kuchuluka kwakukulu kwazinthu zofunikira m'makampani amakono.Mayiko mafakitale padziko lonse, pofuna kuonjezera mphamvu mkulu otsika aloyi zitsulo ndi aloyi kupanga zitsulo, amenenso chidwi kwambiri kuwongolera khalidwe ndi kukulitsa osiyanasiyana mitundu ndi ntchito.Gawo la kupanga m'mayiko linanena bungwe okwana zitsulo, pafupifupi anakhalabe pafupifupi 80%, si chimagwiritsidwa ntchito kwambiri mu nyumba, milatho, njanji, magalimoto, zombo ndi mitundu yonse ya mafakitale makina kupanga, komanso petrochemical masiku ano. mafakitale, chitukuko cha m'madzi, chagwiritsidwanso ntchito kwambiri.
