How to choose erw pipe

The process of Electric Resistance Welding (ERW) utilizes an electric current to create a seam welded along the total length of steel-coil-crafted pipe, thereby producing the aptly titled ‘ERW Pipe’. This thusly created pipe is popularly used in applications necessitating extreme resistance to pressure, such as those found in oil and gas pipeline systems, yet is also well-suited to sewer and water transmitting lines. Available in a broad set of sizes, diameters, and thicknesses, ERW Pipe is one of the go-to selections for many plumbing projects.

Selecting a suitable ERW pipe requires evaluation of its size, diameter and thickness. The internal diameter (ID) is the length from one side to the other across the middle of the pipe, while the external diameter (OD) takes into account the thickness of the wall, allowing for a measurement from edge-to-edge. Ultimately, the wall thickness determines these overall parameters of a pipe.

A broad range of diameters are typically used for ERW pipe, varying from 1/8″ to a maximum of 30″. The standard wall thicknesses available with ERW pipe include Schedule 40, 80, and 160.

When it comes to deciding on an ERW pipe, the use-case must be taken into account. If the ERW pipe is intended for conveying oil or gas, ensure that its grade is suited to this purpose. The same goes for water, presupposing it is the commodity to be transmitted. Different grades of ERW pipe have been crafted for a range of purposes, so ensure you select an appropriate one.

Corrosion-resistance is an essential factor to take into consideration should the pipe be deployed in an area that is vulnerable to degradation. Consequently, it is prudent to ensure the pipe is composed of a material that can stand up to this form of damage.

When on the hunt for an ERW pipe, it is essential to find a reputable producer that provides warranties on their products. After all, there is a world of manufacturers out there, each one offering a range of sizes, diameters, and thicknesses of their respective pipes.

When deciding on an ERW pipe, acquiring expert advice is essential. The pipe must be the appropriate size, diameter, wall thickness and grade for the required purpose.
