API 5L x60 ning materiallari nima
API 5L x60 po'lat quvuri Amerika neft instituti (API) tomonidan API-ning 5L standartiga muvofiq ishlab chiqarilgan po'latdan yasalgan po'lat quvur. Ushbu standart quvur liniy xususiyatlarining keng doirasini qamrab oladi, unda x60 quvurning minimal kuchlanishining kuchi 413 MPa ekanligini anglatadi. Ushbu turdagi quvur asosan neft va gaz uzatish va boshqa sohalarda qo'llaniladi va uning mukammal mexanik xususiyatlari va ishonchliligi tufayli dunyo atrofidagi neft va gaz uzatish tizimlarida keng qo'llaniladi.
