Improve Corrosion Resistance by Lowering Sensitivity during Welding

Pipes form an integral part of many industries including foodstuff process and packaging, oil and gas, transportation, and construction. The high utility of pipes has augured the change in many sectors to use them for increasing the efficiency at the workplace.

High utility of pipes

For instance, for conveying a fluid over a long distance, the manual method of carrying and depositing the material will prove time consuming and laborious. Instead, the use of pipes to convey the needed material in the proper manner helps you save time and effort. For this reason, people use pipes a lot in a variety of applications. To place your order for your construction or industry, contact the ERW Stainless Steel Pipe Tubes Wholesaler for the best price. He will also tell you the delivery schedule so you can take possession of the order.

The stainless steel ERW pipe differs from the standard stainless steel pipe in one major way. It has a weld joint running throughout the length of the pipe. This is due to the method of manufacture of the ERW pipe. In this, they roll the steel sheet lengthwise and then weld them. The Electric Resist Welded (ERW) pipes are cold rolled by pulling the ribbons of steel through rollers. Then, they fuse them into a tube and fuse them with an electric charge.

Versatility of ERW pipes

The application of ERW pipes is for low pressure or medium pressure applications. They find use in the oil and gas industry or for conveying water. You have pipes with different types of finishes. Bare pipes also find a use but they use coated ones. When you weld, take care to use the proper filler metals. Use more time with your joint preparation and maintain the cleanliness to ensure the welding process gets done well.

Get your pipes from a standard Stainless Steel ERW Pipes Manufacturers to make sure that the quality of the pipes is good. You can visit the website of the manufacturer and read the customer reviews there. This will give you a picture of what you may expect from them. You can do an onsite check by visiting their factory and see whether they have followed the prescribed standard in the manufacturing process. Then, you can place your order.

Decrease sensitivity of the weld

The corrosion resistance will drop due to the sensitization of the steel pipe. Sensitization depends on the chemical reaction between the base metal and the filler metals also. In the stainless steel, chromium oxide helps the steel become stainless. Chromium oxide prevents the formation of rust. In the welding process, you raise the carbon levels in the weld and the nearby heat zones. This leads to the formation of chromium carbides. These carbides prevent the formation of chromium oxide and this allows the formation of rust on the pipes. You can combat sensitization by decreasing the carbon base or avoid carbon in the welding process.

When you take care to see that you have used the proper method and material to make the welds, the pipe will meet the standard specified by the industry. Also, the corrosion resistant qualities will remain for a long time.
