Os colares de perfuração são uma articulação integral de serviço pesado que é construído a partir de uma barra sólida do aço de liga modificado por AISI 4145H. Nossos colares de perfuração padrão são fornecidos com uma condição de acabamento de superfície "como enrolada". Todas as barras padrão recebem tratamento térmico que lhes fornece as propriedades mecânicas necessárias.
As barras são então trepadas e flutuadas.? Todos os nossos colares de perfuração são fabricados de acordo com a API Spec 7, Q1 e prática recomendada 7G, conforme aplicável. ASTM A519 ASTEM ASTM A213
