There are mainly three types of API 5l steel pipe, like seamless steel pipe, stainless steel pipe and so on. Here we will talk something about the seamless steel pipe. Generally, there are various kinds of steel pipes that can be found very easily both in domestic and international markets. They are designed with different materials and manufacturing techniques to satisfy different kinds of requirements. For example, they can be used to transport water, natural gas, air and so forth.
The seamless steel pipe as one of the API steel pipe, is made using an extrusion mold. It is different from the welded pipe which is produced by rolling a sheet of steel into a tube and welding the seam. Frankly speaking, seamless steel pipe is more expensive than the welded steel pipe. The seamless pipe can bear higher pressure than the welded steel pipe. One of the greatest advantages of using seamless steel pipes is the increased pressure ratings.
Whether you know or not, the most weak point of the welded steel pipe is the welded seam. However, there is no seam on the seamless steel pipe. Hence the tensile strength of seamless steel pipe is uniform around the entire circumference of pipe. Although it is more expensive to use seamless pipe, it allows for smaller wall thickness and pipe weight which can affect design and costs.
Different from the welded steel pipe, seamless steel pipe maintains its round cross-section since it is a continuous extrusion of the alloy. It takes advantages of true roundness of the circumference. The round cross-section is important during installation and the addition of pipe fittings.
What's more, seamless steel pipe is easier to design than the welded steel pipe. Compared with other steel pipes, the seamless pipe is more safe and reliable. Another advantage of using seamless steel pipe is its strength under loading.
