Advantages of using seamless steel pipe in your project

There are two major categories of steel pipe in the current steel pipe market: welded steel pipe and seamless steel pipe. 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.

Seamless pipe is manufactured based on the diameter or the ration of diameter to wall thickness. The normal raw material is a round spool section preheated in a rotary furnace, or for larger diameters a hollow section preshaped in a perforation press, which is then prerolled in a rotary rolling mill. For steel pipe manufacturers, in the manufacturing of longitudinally welded pipes, either individual steel plates or coils are used as raw material. The pipes are produced in a series of different, sequenced process stages, including cold forming, welding, heat treatment, calibration and non-destructive testing.

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. However, 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.

Hot dipped galvanized steel pipe has been considered popular a lot among many users today. For one thing, the galvanization process protects the steel from rusting damage that can occur during transportation, installation and service. The zinc layer on the surface of pipe can form a barrier protection for steel products to extend the service life in applications. For the other thing, this layer is also resistant to wear and scratch, which makes the steel look more attractive. With the layer of protection, pipes can be used in outdoor areas, and can withstand the harm from some of the environmental effects. If you choose a galvanized pipe, you can avoid the cost of maintaining and replacing corroded pipes. With galvanized pipe, your pipes can last a lot longer than a non galvanized one, which will save you a lot of money in the project.
