Product Description

Type of stainless steel pipe tube

As a manufacturer and supplier of high-quality stainless steel pipe & tube in China, Metal in China® produces stainless steel welded pipe & tube and seamless stainless steel pipe & tube. You can also Contact our stainless steel pipe & tube salesman to specify to buy stainless steel pipe & tube with hot-rolled or cold-rolled specifications.

Stainless steel pipes are generally stainless steel round pipes. Stainless steel pipes are mostly used in gas and liquid transportation.Stainless steel tubes are distinguished from stainless steel tubes and are divided into stainless steel round tubes, stainless steel square tubes and stainless steel rectangular tubes.Stainless steel tubes are mostly used in medical equipment with precise outer diameters.

difference between tube and pipe

The term “pipe” and “tube” are often used to describe the same product, but it is important to know the difference. Though they share the same cylindrical shape, steel pipes are measured by the interior diameter (ID), whereas steel tubes are measured by the outside diameter (OD) and wall thickness. Another difference is that pipes are used to transport fluids and gases, while tubes are used to build parts or structural components. 

difference between seamless pipe and welded pipe

When comparing different types of stainless steel pipe & tube, there are a few factors that should be taken into account.Just like many other metal products, the forming method changes the properties of the finished products in distinct ways. From strength and corrosion resistance to speed and cost of manufacturing, welded and seamless are uniquely suited for specific tasks.

Welded Stainless steel pipe tube

Welded pipe & tube is produced by rolling strips of stainless steel into a tube and then welding along its full length. After welding, the weld seam, or bead, can be refined by cold rolling and forging methods or left as is.

welded pipe manufacturing process
304 welded stainless steel pipe tube

Cold forming results in smoother finishes and tighter tolerances. Welded tubing can even be drawn like seamless tubing to offer a better weld seam, and surface finish. Welded tubing can also be produced with thinner walls on larger diameter tubes, compared to seamless tubing. Because welded tubing requires less processing, it is typically quicker to produce as well as lower in cost than seamless tubing.

The down side of welded tubing comes in the form of high pressure and heavy wall applications. The long welded seam causes a stress concentration point, reducing pressure ratings to 80% of comparable seamless tubing. Also, the stainless material used to create welded tubing must be thin enough to roll effectively. Therefore, heavy wall tubing is less feasible as welded tubing.

seamless Stainless steel pipe tube

To make seamless tubing, the first step is to form a seamless pipe known as a hollow/mother tube. Starting with solid round stock, the billet is first drilled through then heated and forced through a narrow die. The center of the hollow tube is supported during this process by a long rod known as a mandrel. Next, the mother tube is put through a pilger mill.  This machine uses a pair of rolling dies and a second mandrel to elongate and reduce the tube to size.

seamless stainless pipe manufacturing process

This process can quickly reduce the tube cross section by as much as 90% in a single run. However, pilgering is not well suited for smaller diameter tubing.

For small diameter tubing, drawing is a better option. In this process, the mother tube is crimped for grasping on one end, then pulled through a narrowing die. By doing so, the tube is narrowed and elongated.

How to Make Seamless Stainless Steel Pipe

This process may need to be repeated several times to achieve the size reduction needed.

Seamless tubing can contain higher pressure because it does not have the large stress concentration point that welded tubing has. Additionally, seamless tubing often has a cleaner surface finish meaning it is less susceptible to pitting and corrosion. However, there are many more steps needed to manufacture seamless tubing. Because of this, seamless takes much more time to produce and can be more expensive than its welded counterpart.

cutting Service

For parts that require extremely high wear resistance, we use abrasive waterjet cutting to maintain hardness throughout the part without creating a heat-affected zone. For thicker plates up to 200mm, we use precisely controlled CNC oxy-fuel cutting. For products requiring high cut quality and dimensional tolerances, we use high-definition underwater plasma cutting to maximize plate performance in abrasive applications.

frequently asked questions

What is stainless steel tubing used for?

What is the difference between 304 and 316 stainless steel tubing?

Stainless steel tubing is a versatile material used for structural applications. Widely used throughout numerous industrial sectors, stainless steel tubing sizes and varieties vary considerably depending on the application requirements.

The key difference between 304 vs 316 stainless steel that makes them different is the addition of molybdenum, an alloy that drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum, but 304 does not.
