API 5CT Steel Pipe
PRODUCT DESCRIPTION
API 5CT Steel Pipe Description
API is an acronym for the American Petroleum Institute and is considered the most authoritative and comprehensive principle in the oil and gas industry. API 5B and API 5CT are mainly used for oil casing. API 5CT oil casing can be divided into seamless steel pipe and welded steel pipe, welded steel pipe mainly refers to the straight seam steel pipe, large diameter oil casing is generally submerged arc welding straight seam steel pipe.
