China Short Drill Pipe Manufacturing
Tsanangudzo:
Hardbanding: Majoini ezvishandiso uye dzimwe nguva muviri wepombi yekubooresa ipfupi inogona kusungirirwa kuti iwedzere kuramba kupfeka uye kuora.
End Connections: Magumo ekubatanidza anowanzo API kubatana kunobvumira pombi kuti ibatanidzwe kune zvimwe zvikamu mudhiri tambo.
Giredhi: Giredhi repombi yekuboora pfupi inoreva kusimba nekusimba kwepombi. Giredhi rinowanzotarwa nekusimba kwegoho rezvinyorwa.
Tsanangudzo:
Short drill pombi chishandiso chekugadzirisa kureba kwechigadziro chemudziyo wekuchera kuti usvike pane chimwe chinangwa chehunyanzvi mukuchera. Maererano nechimiro chepfudzi, yakakamurwa kuva chimiro chepfudzi yakatsetseka uye yakananga pfudzi chimiro.
Pfupi chibooreso pombi akatevedzana zvigadzirwa anonyanya kushandiswa oilfield mushandisi kurerukirwa pamwe drill pombi mbiru. Yakagadzirwa kubva kune yakakwirira-simba alloy structural simbi mushure mekupisa kupisa, mechanical performance, uye joint thread inopindirana nezvinodiwa zveAPI.
