API 5CT R95

API 5CT R95 is a type of steel pipe that is commonly used in the oil and gas industry. It is designed to protect well casings and tubing from corrosion and abrasion. API 5CT R95 is part of a family of products known as OCTG (oil country tubular goods). OCTG products are made from steel pipes that are used in drilling and production operations. API 5CT R95 is available in a variety of sizes and lengths to meet the needs of different well applications.
