API 5L X42 Pipe

API 5L X42 Pipes is a type of pipe that is used conveying oil and gas materials over long distances. The X42 Pipes is called the line pipes and X42 is one of the many grades that are available within this specification. The American Petroleum Institute monitors the material grades, standards and nominal sizes of the X42 Pipes Material and the products. The materials can vary depending on the mechanical properties required by the line pipes. High temperature services would require higher mechanical properties and the low temperature; low pressure services can use some lower grade Api 5l X42 Pipes types.

The specification covers both seamless and welded pipes. There are product specification level 1 and 2 in this specification as well. The Api 5l X42 Psl2 is used with applications that require higher mechanical properties such as high pressure containment, high temperature tolerance and high corrosion resistance. The Api 5l X42 Psl1 Pipes has lower mechanical properties which makes it cheaper and frequently used. The industries such as domestic water supply, oil and gas pipes lines, natural gas processing plants all use both of these pipes types interchangeably.
