ASTM A53 Giredhi B Seamless chigadzirwa chedu chinonyanya kufarirwa pasi peichi chirevo uye pombi yeA53 inowanzopihwa zvitupa zviviri kuA106 B isina musono pombi.
ASTM A53 Giredhi B ndiyo zvinhu zviri pasi peAmerican steel pombi mwero, API 5L Gr.B iriwo American standard material, A53 GR.B ERW inoreva kupikisa kwemagetsi welded steel pombi yeA53 GR.B; API 5L GR.B Welded inoreva zvinhu Welded steel pombi yeAPI 5L GR.B.

(Cherechedza: Aya ndiwo mashoko akapfupikiswa kubva kuASME Specification A53. Ndokumbira utarise kune chaiyo Standard kana Mataurirwo kana kutibata kuti uwane rumwe ruzivo.)
ASTM A53 isina musono simbi pombi iAmerican standard brand. A53-F inoenderana neChina's Q235 material, A53-A inoenderana neChina's No. 10 material, uye A53-B inoenderana neChina's No.
Nzira yekugadzira
Seamless simbi pombi yekugadzira nzira yakakamurwa kuita inopisa-yakakungurutswa uye inotonhora isina musono pombi.
1. Kugadzirwa kwepombi yesimbi isina musono inopisa: chubhu billet → kudziyisa → perforation → matatu-roller/kuchinjika-kutenderedza & kuenderera mberi → de-pombi → saizi → kutonhora → kutwasanudza → hydraulic test → kumaka → musono pombi yesimbi ine leverage effect yaonekwa.
2. Nzira yekugadzira inotonhora inokweva seamless simbi machubhu: chubhu isina chinhu → kudziyisa → perforation → musoro → annealing → pickling → oiling → yakawanda inotonhora kudhirowa → blank chubhu → kupisa kupisa → kutwasanura → hydraulic test → kumaka → kuchengetedza.
Applications
1. Kuvaka: pombi iri pasi, mvura yepasi, uye kutakura mvura inopisa.
2. Mechanical processing, kutakura maoko, kugadzirisa michina michina, nezvimwe.
3. Magetsi: Kuendesa gasi, Hydroelectric power fluid pipeline
4. Anti-static machubhu emagetsi emhepo zvirimwa, nezvimwe.
