Specifications of Api 5l X52 SMLS Thick DN150 DN200 Sch 40 CS Seamless Steel Petroleum Pipes

These API 5L X52 seamless steel pipes are built tough for demanding oil and gas pipeline systems. They meet the strict API 5L specification for line pipe. The X52 grade means the steel has a minimum yield strength of 52,000 psi. This high strength is vital for handling the pressures found in petroleum transport.

The pipes are seamless (SMLS). They are formed without welding a seam along their length. This seamless construction makes them inherently stronger. They are more reliable under high pressure. They resist leaks better than welded pipes. This is especially important for critical pipeline sections.

Available in common sizes DN150 (6 inches) and DN200 (8 inches). Both sizes come in Schedule 40 (Sch 40) wall thickness. This schedule provides a good balance. It offers strong pressure containment. It keeps the pipe weight manageable for installation. Sch 40 is a standard thickness widely used in mid-pressure oil and gas applications.

Carbon steel (CS) is the base material. This steel offers good strength and durability. It performs well in typical pipeline environments. Proper coatings and cathodic protection are still needed for long-term corrosion resistance underground or underwater.

Manufacturing involves piercing solid steel billets. The steel is heated and shaped into a hollow tube. This process ensures a uniform structure throughout the pipe wall. The pipes undergo rigorous testing. This includes hydrostatic testing to check for leaks under high water pressure. Non-destructive testing (NDT) methods like ultrasonic or radiographic inspection scan for hidden flaws. These tests guarantee the pipes are sound and safe for operation. API 5L certification confirms the pipes meet all required chemical and mechanical properties.

5 FAQs of Api 5l X52 SMLS Thick DN150 DN200 Sch 40 CS Seamless Steel Petroleum Pipes

What is API 5L X52?
API 5L X52 is a steel grade standard. This standard is set by the American Petroleum Institute. X52 means the pipe has a minimum yield strength of 52,000 psi. This strength is important. It helps the pipe handle high pressure safely. The pipe is made for transporting oil and gas.

What sizes do these pipes come in?
These pipes are available in DN150 and DN200 sizes. DN stands for Diameter Nominal. DN150 is about 6 inches in outside diameter. DN200 is about 8 inches in outside diameter. Schedule 40 tells you the wall thickness. Schedule 40 is a common thickness for standard pressure piping.

What does Schedule 40 mean?
Schedule 40 refers to the wall thickness of the pipe. It is a standard classification. For DN150 pipe, Schedule 40 wall thickness is about 7.1 mm. For DN200 pipe, Schedule 40 wall thickness is about 7.9 mm. This thickness provides good strength. It balances pressure handling and material use.

Why use seamless (SMLS) pipe?
Seamless pipe means the pipe has no welded seam. It is formed from a solid steel billet. This process makes the pipe very strong. It has uniform strength all around. Seamless pipe is better for high pressure. It is better for critical applications like oil and gas lines. Welded pipe has a seam that could be a weak point.

Where are these pipes mainly used?
These pipes are designed for the petroleum industry. They transport crude oil. They transport natural gas. They transport refined petroleum products. They are used in gathering lines. They are used in transmission pipelines. They are used in distribution networks. The API 5L standard ensures they are safe and reliable for these uses.
