ERW pombi chiyerozviri sezvinotevera:
API 5L, ASTM A53 B, ASTM A178, ASTM A500/501, ASTM A691, ASTM A252, ASTM A672

API 5L Standard inotarisira gasi uye mvura muindasitiri yemafuta negasi sereferensi, iyo inoshandiswa seamless simbi pombi uye welded simbi pombi, kusanganisira yakajairika port uye chiteshi, pombi socket port uye yakananga rwizi chubhu (TFL) uye chiteshi chine imwe. kubatanidza tube processing.

ASTM A53 pombi yakagadzirirwa kushandiswa kwemakanika uye kumanikidza uye inogamuchirwa kune zvakajairika kushandiswa muutsi, mvura, gasi uye mhepo mitsara.

ASTM A178 zviyero zvemagetsi-resistance-welded machubhu ane hushoma-madziro-ukobvu akagadzirwa nekabhoni simbi uye kabhoni-manganese simbi kuti ishandiswe mumachubhu ebhailer, mafirita ebhailer, flue inopisa, uye magumo akachengeteka.

ASTM A500 inovhara inotonhora-yakaumbwa welded uye isina seamless kabhoni simbi kutenderera, sikweya, rectangular, kana yakasarudzika chimiro chechimiro tubing yeakasungwa, akarukwa, kana mabhaudhi ekuvaka mabhiriji uye zvivakwa, uye nezvinangwa zvakajairika.

ASTM A691 inovhara kabhoni uye alloy simbi pombi, yemagetsi-fusion-yakaiswa simbi yekuzadza yakawedzerwa, yakagadzirwa kubva mukumanikidza-mudziyo-yemhando yeplateti yekuongorora kwakati uye mazinga esimba uye akakodzera kune yakanyanya-kudzvanywa sevhisi pakupisa kwakanyanya.

ASTM A252 inovhara zita remadziro cylindrical simbi pombi mirwi umo silinda yesimbi inoshanda senhengo yekusingaperi inotakura mutoro kana segoko kugadzira akakanda-mu-nzvimbo kongiri mirwi.

ASTM A672 inovhara magetsi-fusion-welded simbi pombi ye-high-pressure sevhisi pane tembiricha ine mwero.
