What is API steel pipe?

The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe. This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil. Size range is limited only by manufacturer’s capabilities.

What are the properties of steel pipe?

Carbon steel pipe is the most commonly and widely used in the gas project field. Its main advantages are: high strength, good toughness, bearing stress, impact resistance and rigor, good plasticity, ease of welding and thermal processing, thin wall thickness, to save metal.

What is X42 steel pipe?

API 5L X42 pipe also called L290 pipe (by ISO 3183), named by minimum yield strength 42100 Psi or 290 Mpa. It’s a higher grade than Grade B where API 5L has various grades up to X100, so x42 pipe is an low-medium level, and it requires large quantities in most of pipelines for oil and gas transmissions.

What is the purpose use of standard steel pipe?

Steel pipes are used to transport products such as oil, gas, and water, and are suitable for long-term installations.

Where are steel pipes used?

Steel pipes are the most commonly used pipes in water supply systems. They are also used in pipelines for natural gas, and sewerage systems.

Where ERW pipe is used?

ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge. It is mainly used for low/ medium pressure applications such as transportation of water / oil.

What is ERW steel pipe?

Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond.

What kind of pipe is API 5L X80?

These API 5L X80 PSL2 Line Pipesare broadly utilized for pipeline transportation systems in the petroleum, gas, water, and natural gas industries. API 5L X80 PSL 2 Pipes of American Petroleum Institute specification covers seamless and welded steel line pipe.

What does X80 stand for in steel category?

X represents the pipeline steel in the API Spec 5L standard, 80 is the strength grade, the unit is kpsi, and X80 is the pipeline steel with a minimum yield strength of 80 kpsi, which is converted to a metric unit of approximately 555 MPa. The X80 is an American classification of high strength pipeline steel.

How big is a high Nb X80 pipe?

In this work, the chemical composition and mechanical properties of high-Nb X80 grade steel pipes with a diameter of ϕ 1,219 mm and a wall thickness of 22 mm, which are coiled by steels manufactured by three mills, have been analyzed.

What is the tensile strength of X80 grade pipe?

Since the X80 strength grade line pipe belongs to the high steel grade product in the pipeline pipe, the strength requirement of the steel pipe is high, and the PSL2 technical grade product limits the product strength, that is, the yield strength is 555~705MPa, and the tensile strength is 625~825MPa.
