Product Introduction
API 5CT is a specification for casing and piping used in the oil and gas industry. It includes several grades of seamless and welded steel pipe for different applications.

For pipeline applications, the API 5L specification is typically used. It covers seamless and welded steel pipe used to transport gas, water and oil in the natural gas and oil industries. the API 5L specification includes several grades such as A25, A, B, X42, X46, X52, X56, X60, X65, X70, X80 and X100. each grade has specific chemical composition and mechanical property requirements.

Whether you need standard length and diameter pipes and tubing or you need high strength, high tensile, heavy wall linepipe requirements for deep sour wells, drilling, offshore drilling and production, arctic exploration and production, or you need standard linepipes for natural gas, oil or water transport,GNEE can meet the demands of your company. All products are industry standard conforming to or exceeding API, ASTM, ASME, ANSI and other national and international standards.
