4. About API 5L Pipes
The American Petroleum Institute specification API 5L is mostly used for the transportation of natural
gas and petroleum.
These API 5L pipes are both seamless and welded. Their main purpose is the transportation of
water, oil and gas from one location to another. The capability of the manufacturer ascertains the
size of the pipe.
An API 5L pipe is manufactured by adhering to the specifications laid down by the International
Organization for Standardization (ISO) 3183.
It standardizes the criteria for the materials, equipment and offshore structures for petrochemical,
petroleum and natural gas industries.
PSL 1 and PSL 2 are the two (Product Specification Levels ) that have been recognized by the
technical committee.
API 5L Pipes have many variants starting from API 5L X42 PSL 1 / PSL 2 till API 5L X80 PSL 1/ PSL 2

8. About Seamless Pipes
Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing
rod to create the hollow shell. As the manufacturing process does not
include any welding, seamless pipes are perceived to be stronger and
more reliable

9. About LSAW Pipe & DSAW Pipe
In LSAW pipes, the welding is longitudinal, which means that steel (hot
rolled coil plate) is rolled into a pipe and the seam is welded
longitudinally.
Double submerged arc welded pipe (DSAW) derives its name from the
welding process wherein the welding arc is submerged in flux while the
welding takes place. Both inside and outside welds are required and are
usually accomplished in separate processes, hence the word "double
