Structural steel Pipe-ERW Steel Pipe
People have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists who diverted water from streams and rivers into their fields. Archeological evidence suggests that the Chinese used reed pipe for transporting water to desired locations as early as 2000 B.C. Clay tubes that were used by other ancient civilizations have been discovered. During the first century A.D. , the first lead pipes were constructed in Europe. In tropical countries, bamboo tubes were used to transport water. Colonial Americans used wood for a similar purpose. In 1652, the first waterworks was made in Boston using hollow logs.Read more -
Methods of Manufacturing used in the Metal Pipe and Tubing Industries-ERW Steel Pipe
Also referred to as Electric Resistance Welded or ERW tubing, is produced when a strip of steel is passed through rollers to form the desired shape. The seam is then welded, forming a flash along the length on the inside and outside of the tube. The weld is then tested to ensure it meets the standard. Once the weld passes the testing process the tubing is formed to the exact size, straightened, and cut to length. ERW tube and pipe is available with the Weld flash in, flash removed or controlled (typically to .010”).Read more -
HOW IS STAINLESS STEEL TUBING PRODUCED?-China Steel Pipe
Raw material begins in the form of hot extruded seamless pipe, which is then cold reduced and processed through tube reducers in a long, straight form. Cold reducing is the most effective manufacturing method for longer lengths of tubing. Rolled pipes are cut to the required lengths and cleaned to remove debris in preparation for heat treatment, which is applied to remove any stresses that could occur during the formation or welding process.Various heat treatments can be used for tubing manufacturing, particularly annealing – this improves the structure of the metal and makes it more ductile for use in applications.Read more -
Welded Tubing Manufacturing-ERW Steel Pipe
Though both the words tube and pipe are often used interchangeably, largely because both are hollow shaped, there are important distinctions between the two when determining welded vs. seamless tubing needs. Tubes are measured by the outside diameter (OD) and wall thickness. A pipe, on the other hand, is measured by its inside diameter (ID). In terms of functionality, tubing is generally used in structural and aesthetic applications whereas piping is used for transporting fluids, liquids, and gases.Read more -
How Are Welded Tubes Made?- ERW Steel Pipe
Manufacturing welded tubing on a large scale is a complex process that involves several steps.Metal coil is first selected using a thickness that will later match the thickness of the finished tube wall. The coil must also be wide enough so that the desired circumference and diameter can be achieved.The coil is fed through a series of dies and formed to shape. This brings two edges of the coil width towards each other until a tube is formed with one edge touching the other.A welding process is used to join these two edges together.Depending on the welded tube manufacturing process, the excess weld reinforcement may be removed at this time. The newly formed tubing may also undergo a heat-treatment process depending on the desired specifications.The tube is then cut to the desired length.Read more -
How Seamless Stainless Steel Tubing is Made-ERW Steel Pipe
The terms ‘tubing’ and ‘piping’ are often used interchangeably when talking about sanitary pipe fittings and valves, but there is a distinction. Tubes are measured by the outside diameter and wall thickness because they’re primarily used for aesthetic and structural purposes. Pipes, on the other hand, are measured by their inside diameter because pipes are used specifically for transporting liquids and gases.Read more -
How is Steel Pipe Manufactured?-ERW Steel Pipe
The first step in the manufacturing process of steel pipes is the selection of raw materials. As you could guess, the primary material used during this process is steel. Steel is an alloy made from iron and carbon, with the carbon content in the steel being a large determinant in the strength and durability of the finished product. It may also contain other materials like nickel, chromium, and molybdenum to improve specific properties of the product.Read more -
The Process of Manufacturing Stainless Steel Pipes and Tubing- Welded Steel Pipe
To begin our process, we first need to go through the rolling and welding stage. The stainless steel is placed through a checking process and cut at the edges in this stage. The stainless steel is pushed through and morphed into its required tubular size with a rolling machine. After being pressed and turned through the rolling machine, the edges are welded through a heating process called TIG. The TIG welding process joins the rolled metals together using an electric arc that has a built-in electrode.Read more -
Understanding the Manufacturing Process of Steel Pipes- China Steel Pipe
Steel pipes, also known as steel tubes, are hollow cylindrical constructions manufactured from steel, a strong and flexible material noted for its durability and resistance to corrosion. There are different kinds of steel pipes available, including seamless pipes and welded pipes. Seamless pipes are manufactured without any welding joints, while welded pipes are constructed by joining two pieces of steel using welding techniques.Read more
