  Schedule 20 vs Schedule 40 steel pipe

  In the field of pipeline engineering, there are many types of steel pipes, and different application environments have different requirements for steel pipes. Steel pipes are divided into different grades according to the wall thickness, among which Schedule 20 and Schedule 40 steel pipes are the most common. Both types of steel pipes are widely used in the industrial and commercial fields, especially in the process of conveying liquids and gases. This article will explore the characteristics, application differences and selection considerations of Schedule 20 and Schedule 40 steel pipes in depth to help you make an informed decision in your specific project.

  ERW Pipe Manufacturing Process

  ERW stands for Electric Resistance Welding and is primarily used to describe a specific method in pipe manufacturing. In this process, two unwound coils of steel plates are joined together without welding filler wire or metal. Instead, the steel plates are joined together by passing an electric current and applying a constant force. Unlike other pipe manufacturing methods you may be aware of, ERW pipe manufacturing does not start with a billet and then further refined through a perforator.

  Black Steel Pipe VS ERW Steel Pipe

  The main difference between black steel pipe and ERW steel pipe lies in their manufacturing process and application range. Black steel pipe is produced by forging process, while ERW steel pipe is manufactured by resistance welding process. ERW steel pipe is made of very fine hard steel, while black pipe is usually made of forgeable steel. The application of black steel pipe is mainly concentrated in gas pipelines and hot water circulation systems in houses, while the use of ERW steel pipe is more extensive, covering oil and gas pipelines, structural engineering and industrial applications.

  ERW Pipe Meaning

  ERW steel pipe, or "Electrical Resistance Welded Pipe", refers to a steel pipe produced by resistance welding technology, with the weld parallel to the pipe body. This type of steel pipe is formed by hot-rolled coils through a forming machine, and the edge of the tube is heated to a molten state by the skin effect and proximity effect of high-frequency current, and then pressure welding is performed under the action of extrusion rollers to form a weld. This weld is formed by melting the steel strip parent material, which ensures the reliability of mechanical strength. Therefore, ERW welded pipes are widely used in various projects, especially in oil and gas transportation, structural engineering and construction industries.

  Standard length range and chart of seamless steel pipe

  The standards for the length range of seamless pipes are divided into international standards and domestic standards. The length range is generally between 3 and 12 meters, but different industries have different requirements for pipe length. Choosing the appropriate seamless pipe length requires considering many factors, including the purpose of the pipe and the required length range, the manufacturer's specifications, prices, etc. ​

  What is black steel pipe?

  Black steel pipe, as the name implies, is a steel pipe whose surface has not been galvanized. This steel pipe is called black steel pipe because of the dark iron oxide coating that forms naturally on its surface. It is widely used in various fields, especially in environments that require high temperature resistance, high pressure resistance and corrosion resistance. The unique properties of black steel pipe make it an ideal choice for transporting important fluids such as natural gas, water, and oil. This article will explore the properties, manufacturing processes, advantages, application areas, and comparisons with other types of steel pipes.

  Schedule 20 Steel Pipe

  Schedule 20 steel pipe is one of the most common and widely used steel types in the steel pipe industry, favored by many users for its excellent performance and affordable price. Due to its cost-effectiveness and high-quality, Schedule 20 steel pipes are used extensively around the world, though different countries have various ways of representing this steel type. Steel pipes come in various grades and categories. Categories are based on the pipe wall thickness, while grades are determined by the pipe's performance. Schedule 20 is one such category, known for its corrosion resistance and ability to operate under low-pressure conditions. The pipe's wall thickness, measured in millimeters, directly influences its pressure-handling capacity. The pressure rating of Schedule 20 pipes provides information about the specific pressure capabilities of the pipes.

  PVC Pipe VS Stainless Steel Pipe

  When comparing PVC and stainless steel pipes and fittings, many people assume that plastic materials are not as durable and long-lasting as metals, especially stainless steel. However, in actual applications, this assumption does not always hold true. While it may seem unreasonable to compare PVC to stainless steel, there are areas where PVC outperforms stainless steel. Below we will compare the performance and characteristics of the two materials from multiple aspects.

  What are the categories of stainless steel pipes?

  Stainless steel pipes are a common type of pipe in engineering, and the most common materials are 201 and 304. It has advantages that other pipes cannot replace. It will be used more and more in engineering, and its use will become more and more popular, and its prospects are promising. In some cases, stainless steel pipes have advantages, especially thin-walled stainless steel pipes with a wall thickness of only 0.6 to 1.2 mm. They are safe, reliable, hygienic, environmentally friendly, and economical in high-quality drinking water systems, hot water systems, and water supply systems that put safety and hygiene first. It has been proven by domestic and foreign engineering practices that it is one of the best comprehensive performance, new, energy-saving and environmentally friendly pipes for water supply systems. Stainless steel pipes are widely used and come in many types. So what are the categories of stainless steel pipes? The following is a detailed introduction to stainless steel pipes.
