What is NORSOK M650?

NORSOK M650 was in fist hand established for qualification of the grades of materials standardised in NORSOK standard M630, which does not include lean duplex SS. The second paragraph may be read to understand that all grades of duplex SS, including lean duplex and hyper duplex, should be qualified.

What is NORSOK standard?

The NORSOK standards are developed by the Norwegian petroleum industry to ensure adequate safety, value adding and cost effectiveness for petroleum industry developments and operations. There are forty years of petroleum experience from the Norwegian continental shelf behind the NORSOK standards.

What is the difference between NORSOK M630 and M650?

Two NORSOK standards that are often referenced are M650, Qualification of Manufacturers of Special Materials and M630, Material Data Sheets and Element Data Sheets for Piping. M650 is a specification that establishes a very detailed process for obtaining approval as a manufacturer.

What is NORSOK M630?

NORSOK M-630 specifies additional material requirements in a collection of material data sheets and element data sheets for use in piping systems designed according to ASME B31. 3 normal and highpressure service.

What are API oil ratings?

The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. It specifies the viscosity grade required for your car’s engine.

What is API in gas?

API gravity is a commonly used index of the density of a crude oil or refined products. API stands for the American Petroleum Institute, which is the industry organization that created this measure. Calculation of API gravity.

How do you read motor oil grades?

In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil’s cold temperature/ cold start performance. The number after the W describes how thick the oil is at the engine’s normal operating temperature.

How do you convert API to density?

The formula can be reversed to find the density of the petroleum liquid. Add 131.5 to the API gravity. The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured. For example, for an API gravity of 50, add 131.5 to obtain 181.5.

Is higher API oil better?

A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude. Lower API indicates a heavier (more dense) crude. Generally, lighter (high API) crudes are more valuable because they yield more high-value light products when run through a refinery.

What 5W-30 means?

5w30 motor oil has a winter viscosity grade of five, meaning it’s less viscous (less thick) at very low temperatures compared to, say, 10w30. It has a hot viscosity grade of 30, which means it is less viscous at high temperatures than an oil such as 5w50.

What is the NORSOK m-650 specification?

A committee of experts works together to constantly maintain and update the specifications but, the Norsok M-650 specification allows any organization, as long as they meet some conditions, to perform qualifications of manufacturers. The standard states that the qualifying organization needs to be acknowledged by the purchaser/end user.

What is the m-650 qualification used for?

NORSOK standard M-650 may also be used for the qualification of manufacturers of various materials, product forms and manufacturing processes according to other specifications or standards when specified by the Purchaser. In such cases shall this be highlighted onto the QTR Front Page.

What does m-650 qtr stand for?
