ASTM A53 Gr.Bndeimwe yemitemo yemapaipi esimbi yakagadzirwa neAmerican Society for Testing and Materials (ASTM). Inotevera inyaya yakadzama yeA53 Gr.B seamless steel pipe:
1. Pfupiso
Pombi yesimbi isina musono yeASTM A53 Gr.B. Pakati pemiyero yepombi yesimbi yakagadzirwa neAmerican Society for Testing and Materials (ASTM), ASTM A53 yakakamurwa kuita mazinga maviri, A neB. ASTM inomiririra seti yemiyero yeAmerica. Mwero weChina weA53A inoenderana neGB8163, iyo yakagadzirwa nesimbi nhamba 10, uye mwero weChina weA53B inoenderana neGB8163, iyo yakagadzirwa nesimbi nhamba 20. Inonyanya kushandiswa kumapombi anoshandiswa zvakanyanya.
2. Maitiro ekugadzira
ASTM A53 Gr.Binonyanya kushandisa tekinoroji yemapaipi asina musono mukugadzira. Tekinoroji yemapaipi asina musono inoreva maitiro ekugadzirisa billet kuita pombi yesimbi ine ukobvu hwakafanana hwemadziro uye nzvimbo dzakapfava dzemukati nedzekunze kuburikidza nemaitiro akadai sekuboorwa kwebillet, kutenderera, uye kuwedzera dhayamita. Kunyangwe chiyero cheASTM A53 chichibvumira kushandiswa kwetekinoroji yemapaipi akasungirirwa kugadzira mapaipi esimbi, mukugadziraASTM A53 Gr.B, tekinoroji yepombi isina musono ndiyo nzira huru yekugadzira.
3. Zvimiro zveChigadzirwa
Ukobvu hwemadziro hwakareba uye dhayamita yekunze: Ukobvu hwemadziro uye dhayamita yekunze yeASTM A53 Gr.B pombi isina musono zvine kunyatsojeka uye zvinogona kusangana nezvinodiwa zvezvivakwa zvakasiyana-siyana zvakaoma.
Kudzivirira kumanikidzwa kwakasimba uye kuramba ngura:ASTM A53 Gr.BPombi isina musono ine simba rekudzivirira kumanikidzwa kwakanyanya uye inodzivirira ngura, uye inogona kushanda zvakanaka kwenguva yakareba munzvimbo dzakasiyana-siyana dzakaoma.
Kushandiswa kwakafara: ASTM A53 Gr.B pombi isina musono yakakodzera masisitimu emapaipi ekutakura gasi, mvura nezvimwe zvinwiwa, kusanganisira kushandiswa mumaindasitiri, masisitimu emvura uye ekudziya.
4. Mhando yakajairika
ASTM A53 GRB standard inoshanda kumapombi esimbi yesimbi yakarukwa (weld) uye isina musono, ichifukidza dhayamita dzakasiyana-siyana dzekunze, ukobvu hwemadziro uye nzira dzekugadzirisa. Zvichienderana nezvinodiwa zvakasiyana zvekushandisa, mapaipi eASTM A53 GRB anogonawo kugadzirwa negalvanized, closed, coated, nezvimwewo kuti awedzere kuramba ngura uye hupenyu hwebasa rawo.
