In modern industrial applications,  spiral steel pipes  have become indispensable due to their high structural strength, ease of construction, and significant cost-effectiveness. They are widely utilized across various sectors, including petroleum, natural gas, water conservancy, and construction. The specific application range of these pipes varies according to diameter, significantly impacting project safety and economic efficiency. In this blog post, we will explore the application scope of the DN200 small diameter spiral steel pipe.  Overview of Small Diameter Spiral Steel Pipe The term "small diameter spiral steel pipe" typically refers to pipes with diameters below 200 millimeters. These pipes have thinner walls and lighter weights, making them ideal for low-pressure fluid transportation and structural support. Let’s delve into their application areas: 1. Municipal Water Supply and Drainage Projects In urban water supply networks, the small diameter spiral steel pip...

  When working within the piping industry, understanding how pipe is measured is crucial for ensuring that you are selecting the right materials for your projects. This blog post will explain the fundamentals of pipe measurement, including Nominal Pipe Size (NPS), wall thickness defined by Schedule (SCH), and the weight of steel pipe.  How is  Pipe  Measured? Pipe is primarily identified by its Nominal Pipe Size (NPS), which is a dimensionless designator that indicates the size of the pipe but does not correspond to actual dimensions. This can create confusion, especially for those new to the piping industry. The outside diameter (OD) of pipes ranging from NPS 1/8 to NPS 12 is defined according to ANSI pipe sizes. For example, in standard practice, a Schedule 40 pipe dimension for sizes up to NPS 12 is roughly equal to its inside diameter (ID). Beyond NPS 12, pipe sizes become less ambiguous. A 14 NPS pipe directly equals a 14” outer diameter. This straightforward co...

When it comes to manufacturing and engineering applications, the surface finish of materials plays a crucial role in determining their performance and longevity. One such material, which has gained significant traction in various industries, is the  carbon steel precision tube . But what exactly is the acceptable level of surface finish for these tubes? What is the Surface Finish of Carbon Steel Precision Tubes? The surface finish of carbon steel precision tubes can significantly vary depending on the application scenario. Generally, the standard surface finish ranges between 0.2 to 1.6 micrometers. However, for high-precision applications—such as those found in semiconductors, precision instruments, and medical devices—the required surface finish can drop to below 0.05 micrometers. This difference underscores the importance of understanding specific industry standards and requirements when it comes to precision tubing. Factors Influencing the Surface Finish Several key factors aff...

This difference underscores the importance of understanding specific industry standards and requirements when it comes to precision tubing. Improving the Surface Finish of Carbon Steel Precision Tubes To achieve an optimal surface finish, manufacturers can consider a variety of approaches: - Using High...

When discussing  fluid pipes , we delve into the essential infrastructure that facilitates the transportation of various fluids such as water, oil, and gas. One of the most significant types of fluid pipes is the  seamless steel pipe . However, it is important to note that not all fluid pipes fall under the category of seamless steel pipes. This article aims to provide a comprehensive analysis of fluid pipes, particularly the relationship and distinctions between fluid pipes and seamless steel pipes. 1. Main Types of Fluid Pipes Seamless Steel Pipes: Seamless steel pipes are the most common type of fluid pipes. These pipes feature a hollow cross-section and, crucially, lack any welds from one end to the other. This design makes them particularly suited for fluid transportation, as their seamless nature allows them to withstand higher pressures and more demanding operational conditions. Seamless-like Steel Pipes: A relatively newer entry into the category of fluid pipes, seamle...
