API 5L X42 seamless pipes are part of the API 5L specification for line pipes used in the oil and gas industry. Manufactured to meet both PSL1 and PSL2 standards, X42 grade offers a minimum yield strength of 42,000 psi (290 MPa), making it suitable for moderate-pressure fluid transport applications. These pipes provide good weldability, toughness, and corrosion resistance.

Key Features

Strong and durable for medium-pressure pipelines
Good weldability and formability
Available in both PSL1 and PSL2 grades
Resistant to cracking and stress corrosion
Ideal for onshore and offshore environments
