What is API 5L X42 SAW Pipe?
API 5L X42 Line Pipes are manufactured as per specifications established by American Petroleum Institute (API). API 5L is a specification of API which defines the standard for the dimension, physical, mechanical and chemical properties of the steel. We also stock the API Line pipe of Top Steel pipe mills who manufacture the API 5L pipes specially for Oil and Gas industry. API 5L X42 Seamless line pipe is produced to the API 5L specification, and is intended for the conveyance of oil and natural gas & other fluids in pipe lines, transmission lines, or gathering lines. Line pipe may also be certified to the ASTM A-1024 specification.
API SPEC 5L is a international standard specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of welded steel pipes for use in pipeline transportation systems in the petroleum and natural gas industries. Pipe Specifications for these pipes regulate usage for standard Grade A and Grade B pipes, with Grade X indicating stronger variants for drilling, production and transport requirements for offshore, arctic, deep well or harsher environments.
API 5L Seamless Line Pipe available in all special steel grades like X42 Pipe/X46 Pipe/X52 Pipe/X56 Pipe/X60 Pipe/X65 pipe/X70 pipe/X80 pipe in PSL-1 & PSL-2. Grades covered by this specification are A25, A, B (and the following “X” Grades), X42, X46, X52, X56, X60, X65, X70, X80. The two digit number following the “X” indicates the Minimum Yield Strength (in 000’s psi) of pipe produced to this grade.

Submerged arc welding is a process in which the joining of metals is produced by heating with an arc or arcs between a bare metal electrode or electrodes and the work. SAW PIPE commonly refer to large diameter weld pipe. SAW means submerged arc weld, it can be classified into L SAW and S SAW. L SAW MEANS lognitudinal welding, S SAW means spiral weld tube.
