Seamless Steel Pipe

Steel pipes are long, hollow tubes that are used for a variety of purposes. In general, they are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld. Specifically, the seamless steel pipe manufacturing starts with a solid, round steel billet. This billet is then heated to great temperatures and stretched and pulled over a form until it takes the shape of a hollow tube.

Today, seamless steel pipe has been widely used in a variety of applications in numerous market sectors including oil and gas pipelines, petrochemical and the construction industry. It is believed that you maybe encounter confusion about how to select the proper steel products for your project. Or you may be concerned on whether to welded pipe or seamless pipe on earth.

As a professional steel pipe manufacturer in China, we would like to give you further information about this type of steel pipe used in applications.

First of all, the greatest advantage of seamless steel pipes is their increased ability to withstand pressure. The weakest point in a welded steel pipe is the welded seam. But because a seamless steel pipe has not been welded, it doesn’t have that seam, making it equally strong around the entire circumference of the pipe. It is also much easier to determine pressure calculations without being required to take weld quality into consideration.

In the next place, although the steel pipe price can sometimes be more expensive than welded pipe. For the one thing, seamless steel pipe is a continuous extrusion of the alloy, meaning that it will have a round cross section that you can count on, which is helpful when you’re installing pipes or adding fittings. For the other thing, this type of pipe has greater strength under loading. Pipe failures and leaks in welded pipes usually occur at the welded seam. But because seamless pipe doesn’t have that seam, it isn’t subject to those failures.

Finally, another benefit of seamless pipes is that they can perform well in certain harsh conditions, both in extremely cold or hot environments.

In short, seamless steel pipes has become the preferred material in an array of commercial pipe applications, including ship building, pipelines, oil rigs, oil field equipment, pressure vessels, machinery parts and offshore rigs today. Based on your specific requirements of applications, you can select the proper pipe for your project soon.
