The production technology of LSAW steel pipe determines its performance

　　Talking about LSAW steel pipe, it is mainly used in oil, gas, liquid coal on land and offshore. Of course, its original material and production process have decided its special characters. Today, our topic would be its features for its function.

　　First of all, internal stress for LSAW steel pipe would be smaller than seamless steel pipe. And it would be uniformly distributed after the full length expansion.

　　Secondly, due to the inside and outside of the welding is made after the tack welding, thus, we should know that this welding process would be stable for customers’ good transportation.

　　In addition, compared with non-longitudinal seamless steel pipe, the length of LSAW steel pipe would be shorter than the seamless one. Thus, the probability of defects occurrence is very low.

　　What’s more, the pipe can be either in very large diameter with thick wall or in very small diameter with thick wall.

Advantages of hot-dip galvanized greenhouse pipe

　　The first aspect is that galvanized pipes have their own advantages in terms of their convenience. We also know that for users, when they use a product, the first thing is to make it very convenient. It has its own lightest weight, so it can be used on its own to give it a high advantage. 　　And it's on its own convenience, it is also reflected in its installation, because it has a good design on the installation, so it can make it very convenient when it is used by itself, for the user There is also a requirement in this respect. Then there is a user who can use it to achieve a good performance on his or her own service life. For the user, when using a product, it is hot. Galvanized greenhouse pipes have high requirements on their own service life. 　　Because the hot-dip galvanized greenhouse pipe is galvanized, it can achieve a high service life when it is used. If it is made of ordinary carbon steel pipe, it is prone to its own rust performance. If the user uses this product...

Application of large diameter seamless steel pipe

 1. Large diameter thick wall seamless steel pipe is used for the manufacture of large shaft and roller assemblies, oil cylinder and hydraulic oil cylinder, mechanical spare parts, mechanical structure, large airports, bridges, wharfs and building structures 2. In our daily life, large-diameter seamless steel pipe is a very common channel, which is mainly used in sewers and water pipes. Our tap water is transported to each of our homes through large-diameter seamless steel pipe. Our domestic water is inseparable from large-diameter seamless steel pipe. The water pipe will also be applied to the large-diameter seamless steel pipe, so that we have a steady stream of water resources. 3. With the development of science and technology, the transportation of gas from south to North has become a simple thing one after another, which is inseparable from the large-diameter seamless steel pipe. The large-diameter seamless steel pipe is mainly used for the transportation of gas and all kinds ...

Perfect delivery of thick wall welded pipe

 At the end of March 2021, Xinyue received the inquiry for thick wall pipe from old customer. Most of the dimensions of the inquiry are small diameter and thick wall thickness. The thickest wall thickness reaches 50.8mm, but the outer diameter is only 609.6mm. Under normal circumstances, this dimension is more suitable for seamless steel pipe. However, in order to save project cost, customer prefer to make welded steel pipe, but the outer diameter of welded pipe is small and the wall is thick, It was a challenge for Xinyue. At the first time after receiving the initial inquiry, Xinyue's spirit of not fearing difficulties drove us to try our best to hold many meetings with the technical team to overcome the difficulties, and finally won the order for 200 tons of thick wall welded pipe. In addition to the thick wall, the project has miscellaneous dimensions, disordered length and small number of single pieces. In order to better serve customer at a high cost, we have nev...
