Welded Stainless simbi pombi inogadzirwa nekugadzira masheets esimbi mune chubhu chimiro uye ipapo welding musono. Ese ari maviri anopisa-akaumbwa uye anotonhora-akaumbwa maitiro anoshandiswa kugadzira isina tsvina tubing, neinotonhora maitiro achigadzira kupera kwakatsetseka uye kushivirira kwakasimba pane kupisa kuumba. Maitiro ese ari maviri anogadzira pombi yesimbi isina tsvina inoramba corrosion, ine simba rakakwirira uye kusimba.

Pombi yesimbi isina tsvinainocheneswawo zviri nyore uye kucheneswa uye inogona kugadzirwa zviri nyore, kugadzirwa nemichina, kana kukotama kugadzira chimiro chakakombama. Uku kusanganiswa kwezvinhu kunoita kuti pombi yesimbi isina tsvina ive sarudzo yakanakisa yezvimiro zvekushandisa, kunyanya idzo uko machubhu anogona kuoneswa munzvimbo dzinoparadza.

Musi waMbudzi 1, 2024, US International Trade Commission (USITC) yakatanga ongororo yechitatu yekuvira kwezuva kweanti-dumping (AD) uye countervailing duty (CVD) pamapombi akaiswa simbi isina tsvina kubva kuChina, pamwe nekudzokorora kwechipiri kwezuva kweAD. mabasa pazvigadzirwa zvakafanana kubva kuMalaysia, Thailand, neVietnam, kuona kana kukanzurwa kweiyo AD uye CVD maodha pamusoro pezvigadzirwa zvingangoita kuti kuenderere mberi kana kudzoka kwekukuvara kwezvinhu kuindasitiri yeUS mukati menguva inofanoona. nguva.

Mapato anofarira anofanirwa kuendesa mhinduro yavo kuchiziviso ichi neruzivo rwunodiwa panosvika nguva yekupedzisira yaZvita 2, 2024, uye zvirevo pamusoro pekukwana kwemhinduro dzinofanirwa kuiswa muna Ndira 2, 2025.

300 series giredhisimbi isina ngurainogadzirwa mumhando yezvigadzirwa zvinosanganisira machubhu esimbi, pombi dzesimbi, uye zvimwe zvakasiyana zvigadzirwa. Ose 304 uye 316 simbi machubhu ane nickel-based alloys ari nyore kuchengetedza, anodzivirira kukora, uye anochengetedza simba nekusimba patembiricha yepamusoro.

Kuona kuti ndeipi giredhi resimbi rakanakira application yako zvinoenderana neyakagadzirirwa application pamwe nemamiriro ekunze akadai setembiricha kana kuratidzwa kune chloride.

• Type 304 Stainless simbi inodzivirira corrosion uye iri nyore kuchenesa, zvichiita kuti ive iyo yakajairika mhando yesimbi isina tsvina inoshandiswa pachubhu nezvimwe zvikamu zvesimbi. 304 simbi isina tsvina machubhu anowanzo shandiswa mukuvaka nekushongedza maapplication.
• Type 316 Stainless simbi yakafanana ne304 stainless pakuti zvakare haina corrosion uye iri nyore kuchenesa. 316 isina tsvina inoita, zvisinei, ine mukana mudiki nekuti asi inoshingirira mukuora kunokonzerwa nechloride, makemikari, uye zvinonyungudutsa. Ichi chekuwedzera chinoita kuti 316 simbi isina tsvina ive mhinduro inosarudzika yezvishandiso uko kunogara kuratidzwa kumakemikari kana yekunze kwekushandisa uko kune kuratidzwa kwemunyu. Maindasitiri anozivikanwa kushandisa 316 simbi isina tsvina anosanganisira maindasitiri, ekuvhiya, uye emugungwa.
