Pipe ea ho Epa Boima ba Boima
Pipe ea ho cheka e boima e kenyellelitsoeng ke sebaka sa phetoho lipakeng tsa molala oa ho cheka le phala ea ho phunya.E ke ke ea fokotsa feela khatello ea maikutlo mabapi le khokahanyo ea molala oa ho phunya le phala ea ho phunya, empa hape e fokotsa ho roala ho OD.
Pipe ea ho cheka e boima e kopantsoeng e entsoe ka karolo e le 'ngoe ea AISI 4145H bareng e tiileng, e ts'oaroe ka mocheso o felletseng, thepa eohle ea 'mele e lumellana le API spec7 khatiso ea morao-rao.
HWDP's wear resistance banding ke ntho e tlwaelehileng mabapi le dikgokelo tsa disebediswa le ho ferekana bohareng.Mefuta ea li-banding tse thata li kenyelletsa Arnco 100XT le100XT.Likhoele tsohle li entsoe ka phosphated, copperized kapa batang.Lihokelo tsohle li na le lisebelisoa tse sireletsang likhoele tsa tšepe tse hatelitsoeng.Lipapali tsohle li entsoe ka likhoele tsa CNC - likhoele tse mahetla a mabeli le likhoele tse khethehileng.
