Los collares de perforación son una articulación integral de servicio pesado que se construye a partir de una barra sólida de acero de aleación modificado AISI 4145H. Nuestros collares de perforación estándar se suministran con una condición de acabado superficial "como enrollado". Todas las barras estándar reciben tratamiento térmico que les proporciona las propiedades mecánicas necesarias.
Los bares se vuelven a hacer y se desvanecen. Todos nuestros collares de perforación se fabrican de acuerdo con la API Spec 7, Q1 y la práctica recomendada 7G, según corresponda. tubería de acero ASTM A519 ASTM A213
