Product Description

API Petroleum Casing

The API petroleum casing adheres to API 5L, the esteemed American Petroleum Institute standards. These guidelines form the foundation of general petroleum casing export standards, hence the term API Petroleum Casing. These casings are primarily classified based on material into K55, J55, N80, and P110. The casing connections include the commonly used short round buckle (STC), long round buckle (LTC), and partial trapezoidal (BTC), along with airtight, threaded, and other special types. North China stands as the primary production hub for API oil casing, which is available in both seamless and welded forms. Seamless pipes, with their superior mechanical properties, command a higher price than welded pipes and are extensively used in oil drilling operations. Our key markets span Southeast Asia, East Asia, the Middle East, West Asia, and Latin America.
