What is a Stainless Steel ERW Pipe?
An ERW (Electric Resistance Welded) pipe is a type of pipe that is manufactured by welding metal sheets or strips using electric resistance. Known for their smooth finish, high strength, and uniformity, SS ERW pipes are widely used in industries such as construction, oil and gas, and water distribution.
Key Features:
- Made with electric resistance welding, ensuring durability.
- Available in various sizes and thicknesses to suit diverse requirements.
- Preferred for applications demanding high strength and corrosion resistance.
What is the Difference Between ERW and EFW Stainless Steel Pipes?
Though both ERW and EFW pipes are widely used, they differ significantly in their manufacturing process:
| Aspect | ERW Pipes | EFW Pipes |
| Manufacturing | Welded using electric resistance. | Welded using electric fusion. |
| Material | Typically thin sheets of stainless steel. | Often thicker plates of stainless steel. |
| Application | Ideal for medium-pressure systems. | Used in high-pressure and heavy-duty systems. |
| Cost | More cost-effective. | Relatively expensive. |
What is the Difference Between ERW and CDW Pipes?
The main difference between ERW (Electric Resistance Welded) and CDW (Cold Drawn Welded) pipes lies in their production process and application suitability:
| Aspect | ERW Pipes | CDW Pipes |
| Manufacturing | Electric resistance welding. | Cold drawing process after welding. |
| Strength | High tensile strength. | Higher precision and smoother surface finish. |
| Applications | Suitable for general purposes like water lines. | Used for precision applications such as hydraulics. |
Applications of Stainless Steel ERW Pipes
SS ERW pipes are versatile and cater to a variety of industries:

Types of Stainless Steel ERW Pipes by Mcneil Instrument
Stainless steel ERW pipes come in different types and sizes, including 304 and 316 types. They are used for high temperature and pressure applications.
Types of stainless steel ERW pipes
- 304L Stainless Steel ERW Pipe: This pipe is strong and can withstand temperatures up to 870°C. It has a minimum yield strength of 205 MPa and a minimum tensile strength of 515 MPa.
- 316 Stainless Steel ERW Pipe: This pipe is resistant to chloride ions. It is commonly used for medium pressure containment.
- ASTM A312 TP304 Seamless Tube: This pipe is made from a single piece of metal and is stronger than a welded pipe. It is used for high temperature and corrosive services.
Sizes of stainless steel ERW pipes
- Schedule 40 Stainless Steel Pipe: The dimensions of a schedule 40 stainless steel pipe depend on its outer diameter and wall thickness. For example, a 4 inch schedule 40 stainless steel pipe with an outer diameter of 4.5 inches and a wall thickness of 6.02 mm has a bore of 102.26 mm.
Grades, Materials, and Specifications of SS ERW Pipes
| Grade | Material | Common Specifications | Applications |
