Stainless Steel Pipes

What Is Stainless Steel Pipes?
 

Stainless Steel Pipes are pipes made of stainless steel in different grades. These pipes are primarily used for creating piping systems for transport of liquid or gas. These pipes are highly resistant to corrosion and rusting.

When transporting highly chemical gases, corrosive fluids, etc., stainless steel pipes are the pipe of choice. You might also refer to these pipes as corrosion-proof conduits.

Since it includes more than 8% of these elements, stainless steel is classified as high-quality alloy steel. Essentially, a thin layer of chromium is applied to the exterior of an alloy metal pipe to serve as a protective coating.

As a result, the outside has no effect on, and can't hurt, the interior environment. The market has a significant demand for these pipes due to their high quality and wide range of sizes. It's a hit not just in India, but everywhere in the world.

They are costly because of the wide range of components they incorporate, which gives them a great deal of flexibility but also makes them susceptible to damage. It's resilient, producing top-notch outcomes even under the worst of circumstances.

Stainless Steel Pipes are used in many different applications, such as:

·  Pharmaceuticals

·  Water treatment plants

·  Food processing

·  Oil and gas processing

·  Textile operations

·  Breweries

·  Automotive components

·  Fertilizers and pesticides

·  Chemical applications

·  Construction

Grades of Stainless Steel

Stainless steel is manufactured in several grades. SS304 and SS316 are the most commonly used grades in the production of steel products. These grades come under the 300 series grade stainless steel. This series of stainless steel contains primarily chromium and nickel alloy. However, molybdenum is also used in some grades. A raise in chromium content increases the resistant to corrosion and rusting. The choice of stainless steel grade for pipes is dependent on the types of application. For instance, SS304 grade is used in food and beverage application because it is highly corrosion-resistant and is easy to sanitize

Which is better 316 or 316L?

What is 316 Stainless Steel?

Stainless steel grade 316, or 316 stainless steel as it is more often known, is a typical austenite-containing stainless steel alloy. The highest carbon level it can have is 0.08%, while the highest molybdenum content is 2% to 3%. These properties—as well as its use in acidic conditions and resilience to pitting and elevated temperature—are all attributable to the inclusion of molybdenum.

Properties:

- With its tremendous strength, it can be shaped into various forms without breaking.

- Its excellent resistance to corrosion and pitting makes it useful in applications where chemicals and acids will be present during fabrication.

- It's aesthetically pleasing and easy to weld.

- A value of roughly 193 GPa is obtained when calculating the elastic modulus.

- Melting point is between 13710 and 13990 degrees Celsius.

- It has a tensile strength of 515 MPa at its weakest point.

- 7.98 g/cm3 is its density.

Applications:

1. Pharmaceutical 

2. Heat Exchanger

3. Photographic Equipment

4. Pumps 

What is 316L Stainless Steel?
 

The carbon content of 316l stainless steel, also known as Grade 316l, is lower than that of 316 stainless steel. Molybdenum and carbon contents of up to 0.03 are found in this compound. As a result, carbide precipitation is mitigated during welding and other sheet metal manufacturing processes thanks to the material's low carbon concentration.

Properties:

1. Excellent creep resistance

2. It may transform into a wide variety of shapes and sizes.

3. 316L has a high temperature of rupture and a high tensile strength.

4. Most noticeably, 316L stainless steel differs from its 316 counterpart in that it has less carbon and molybdenum. This means it is more resistant to corrosion than 316.

Applications:

1. Power Generation

2. Jewelry manufacturing

3. Marine

4. Food Processing 

5. Chemical Industries

6. Water Treatment Companies

316 VS 316 L- The difference
 

The following points will help you choose between 316 and 316L stainless steel for your project:

1. Corrosion Resistance 

When working with extreme conditions, such as high temperatures and corrosion, 316L is the best option. Because of its superior intergranular corrosion resistance, 316L welds will not deteriorate like those made from 316 stainless steel due to its lower carbon content.

2. Cost

The price of 316 and 316L stainless steels are very similar despite the difference in carbon content.

3. Magnetic Properties 

The magnetic response of 316 stainless steel is quite low. Most stainless steel variations (including 316) are austenitic, effectively nonmagnetic, as opposed to basic stainless steels which are ferromagnetic.

However, the austenitic crystal structure of some 316 stainless steel products can be converted into ferromagnetic martensite through operations including cold shaping and welding. 316L steel is more likely to become magnetized than other types of steel.

4. Uses in Daily Life

In a wide range of fields, both forms of Stainless Steel Pipes prove invaluable. 316, however, finds its most common application in the building and maintenance of infrastructure due to its high strength, low ductility, and high resistance to pitting and corrosion under normal conditions. Because of its resistance to welding and chemical corrosion, 316L finds widespread usage in the medical and photographic industries.

Difference Between Seamless And Erw Stainless Steel Pipe?
 

ERW Vs Seamless Pipes- The difference

Every carbon steel pipe, comprising Casing pipe & Tubing pipe, are made using either a seamless or electric-weld providing technique in accordance with API regulations. Seamless pipe and ERW pipe are not the same in many ways. 

Experts have traditionally viewed erw pipes as weaker than seamless pipes, which has cast a shadow on the true meaning of erw pipes. To further improve the erw pipe's resistance to corrosion and oxidation, it is cold rolled after the hot rolling processes. 

These tubes are suitable for both high and low pressure systems. You can get them with a variety of different tube endings, including plain, threaded, and beveled. 

The rolling metal is then welded longitudinally across the length to create an ERW pipe, which stands for electric resistance welding. The difference between ERW and seamless pipes is seen in their cross-sections; ERW pipes have welds, while seamless pipes have not.

Seamless stainless steel pipes are made without the use of any joints or welding and are cast from a solid piece of billet. These pipes range in OD from 1/8 inch to 26 inches and are finished on both the vertical and horizontal dimensions. High-pressure uses are thought to be feasible for these seamless pipes.

Electric resistance welded pipes, or ERW pipes, are made by welding a coil or strip of metal together lengthwise. Common outside diameters for such pipes are 12" - 24". An electric charge is utilized to fuse the steel ribbon that is cold formed into a tube for these pipes. Low to medium pressure systems make frequent use of the pipes. 

Such stainless steel pipes can be purchased in a range of popular diameters, from 2 3/8 inches outside diameter (OD) to 24 inches OD, and in lengths of up to 100 feet. ERW pipe can be finished in a variety of ways, including coated and bare, and processing is done locally according to each client's needs.
