API 5L PSL1 Vs PSL2 Pipes

API 5L PSL1 Vs PSL2 Pipes

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 the 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 which are mostly used in Oil and Gas Industries.
Trio Steel API 5L Pipes suppliers further adhere to the International Organization for Standardization ISO 3183 and it specifies the production of two product specification levels (PSLs): API 5L PSL1 Vs PSL2 Pipes. The previous is a standard quality for line pipe though the last conveys extra mechanical, synthetic properties, and testing requirements. These pipes are recognized and trusted names for organizations working in the oil, flammable gas, and petrol area just as different areas where API 5L Pipes are needed to do tasks.

API 5L Pipe

Types Of API 5L Pipes?

What are the Types Of API 5L Pipes?

 API 5L Pipes When authoring the standards, the technical committee recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2.

API 5L PSL1 Standards :

PSL-1 is a loose standard quality for line pipe. PSL 1 Pipes are used to distribute line pipes. Grades covered by this specification are A25, A, B and “X” Grades API 5L X42 PSL1 Pipes, API 5L X46 PSL1 Pipes, API 5L X52 PSL1 Pipes, API 5L X56 PSL1 Pipes, API 5L X60 PSL1 Pipes, API 5L X65 PSL1 Pipes, API 5L X70 PSL1 Pipes, API 5L X80 PSL1 Pipes. The two digit number following the “X” indicates the Minimum Yield Strength (in 000′s psi) of pipe produced to this grade.

API 5L PSL2 Standards :

PSL-2 contains additional testing requirement, stricter chemical physicals, along with different ceiling limits of mechanical properties, and require Charpy impact testing conditions. Furthermore, additional testing requirements under PSL-2 include CVN testing, non-destructive inspection of seamless products, Read more


What is Stainless Steel Pipe?

Stainless-Steel-PipesStainless Steel Pipes: Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium—the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing. Let’s know more about Stainless Steel Pipes. What is Stainless Steel? Stainless steel, also known as inox steel and is an alloy with a minimum of 10.5%chromium content by mass. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal’s internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present. Stainless steel is used where both the properties of steel and corrosion resistance are required.

What are API 5L Pipes?

API 5L Pipes:

API 5L Pipes are one of the main classifications of pipes. Let’s take a brief look at how they’re manufactured, Composition, Applications as well as some of the potential benefits they present.
What are API 5L Pipes?
API Stands for American Petroleum Institute, In General the API 5L specification provides standards for pipe suitable for use in conveying gas, water, and oil in the natural gas and oil industries.
The API 5L covers seamless and welded steel line pipe. It includes plain-end, threaded-end, and belled-end pipe, as well as through-the-flowline (TFL) pipe, and pipe with ends prepared for use with special couplings.

Understanding Carbon Steel

Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute (AISI) definition says:

Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten,vanadium or zirconium, or any other element to be added to obtain a desired alloying effect;when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.6, copper 0.6.

7 oil and gas projects to watch in 2015

1.Another new Russia – China pipeline
In the wake of the $400bn deal Russia signed this May to sell its gas to China through the under-construction Power of Siberia pipeline, a second November agreement between the two countries may have not made quite as many headlines as it should.
The new contract will see Gazprom supply 30 bcm of gas a year to the Chinese state oil company CNPC, and it will involve more major pipeline work in Russia. China will receive its gas through a new 2,600km pipeline network called Altai, named after one of the regions of western Siberia it will run through on its way to China’s northwestern border with Russia.

Low Oil, Gas Investment to Have Long-Term Impact on Supply, IEA Chief Says

OSLO—The International Energy Agency’s executive director said Monday that global oil and gas investments were expected to drop in 2015 and 2016, marking the first two-year spending decline in decades, and he warned of the long-term impact on supply.

“We have never seen this in the last 30 years, two consecutive years of investment decline,” the IEA’s executive director, Dr. Fatih Birol, told The Wall Street Journal on the sidelines of a Statoil conference. “This will have implications for the oil markets, if not tomorrow then the day after tomorrow.”
The IEA, the energy watchdog of the Organization for Economic Cooperation and Development, has forecast oil prices will pick up slowly toward $80 per barrel by around 2020, as demand keeps growing and the current oversupply is gradually reduced.

The US steel pipe makers, which lodged a complaint against dumping, are Bull Moose Tube Company, EXLTUBE, Wheatland Tube Company and Western Tube and Conduit .

The investigation would be carried for circular welded carbon-quality steel pipes.

EN 10204 3.1 Certification Vs EN 10204 3.2 Certification

Looking for an EN10204, 3.2 Certification?

EN10204 is a Euronorm (issued by the European Community) specification that describes different types of material test reports and certifications.  The standard contains no requirements relative to actual material requirements.  The most common reference is to a 3.1 type certification (3.1 is the paragraph number within EN10204 that describes the content).  A 3.1 certification is simply the common mill test report that reports test results on the lot of material in question, performed by a laboratory (often operated by the mill itself) that is independent of the personnel actually producing the material.  Sending samples to an independent laboratory for testing to the ordering specifications will still result in a 3.1 certification.  It is just being tested by a second source.
