Quality Control of Welded Steel Pipe and Stainless Steel Pipe

Tag: carbon steel pipe,seamless steel pipe

Stainless steel pipe is among the most preferred gas or liquid distribution piping products at present in a lot of nations. High quality stainless steel pipe is relatively light in weight and will never fall to corrosion thanks to its special coasting. What is more, stainless steel pipe is available in coil lengths, and easy to install with the help of fittings, professional staff and mechanical tools. This is why stainless steel pipe has been proven to be reliable and durable since it was first introduced to the piping market decades ago. Standard coil lengths provide long, uninterrupted run capabilities of the stainless steel pipe. In other words, more ground can be covered during the installation process and the cost of unnecessary joints can be largely eliminated since longer lengths not only provide convenience in installation but also allow for significant savings in terms of labor and equipment.

As a matter of fact, stainless steel pipe is suitable for a wide range of applications such as gas distribution and water gathering. In addition, some stainless steel pipe manufacturers take great pride in the quality and workmanship of their piping products because they have comprehensive quality control programs that encompass all the important stages of the stainless steel pipe manufacturing process. This is also the case with some welded steel pipe manufacturers since they have the similar quality control procedures when producing welded steel pipe. And the most difficult part of welding steel pipe is maintaining the weld puddle without overheating the connection.

To be more specific, there are mainly three crucial aspects in the quality control of the piping production. First of all, the incoming steel and the fittings should be carefully inspected and tested to ensure that they meet all the applicable requirements. Then during the piping production, stainless steel pipe or welded steel pipe will be visually examined for any cosmetic defect from time to time. At the same time, a certain number of pipe samples will be collected for physical verification and testing for compliance with customers' requirements. Finally, the finished stainless steel pipe or welded steel pipe is subjected to further inspection to ensure it well meets all the appropriate ASTM specifications and the packaging requirements. What is more, without exception, the finished stainless steel pipe or welded steel pipe is constantly monitored throughout the entire manufacturing process to ensure that they are in accordance with all applicable specifications.

With such a strict manufacturing process, the piping products will naturally have good resistance to most chemicals that it is likely to encounter in the gas or liquid distribution services. Furthermore, with a relatively smooth inside surface, stainless steel pipe or welded steel pipe provides high volume flow and will tolerate most corrosion chemicals.
