X42 pipeline steel pipe is a commonly used pipeline steel pipe that complies with the API 5L (American Petroleum Institute) standard. It belongs to the X-series (high-strength) pipeline steel pipes. The number "42" indicates its minimum yield strength of 420 MPa (approximately 60,000 psi).
X42 pipeline pipes include both seamless and welded steel pipe types. These pipes come with various end forms, such as plain end, threaded end, and socket end. Common connection methods for these pipes include welding, coupling connection, and socket connection.
The primary function of X42 pipeline pipes is to transport extracted oil, gas, and water from the ground to petroleum and natural gas industrial enterprises through pipeline systems.
