Benefits of Stainless Steel Pipes

Sometimes it may be hard to determine if the steel pipe is appropriate for your specific application. There are many different types, grades and standards for stainless steel pipes, and a number of challenges may arise in choosing the best for its intended use. Other procedures, such as welding, will present their own set of variables, as will the external structure of the application. For example, will the pipe be indoor or outdoor, exposed to chemicals or harsh weather conditions? Knowing the answers to these questions will make it much easier to choose the appropriate pipe.

Stainless steel 304 pipes is commonly and widely used in many industries where its strength and resistance to corrosion are incredibly valuable. It is often used where thermal and chemical resistance, sanitation and lower maintenance costs are significant. Whether you are a first-time designer or a highly experienced construction engineer looking for a better type of material, the industry in which you work is most likely to require a certain grade of stainless steel to be used.

There are several benefits and drawbacks involved in trying to determine whether stainless steel pipes are right for your chosen application. Most of these will relate to your industry needs (if any) for pipes, in addition to the specific requirements that your application will have to meet. For example, the medical industry will inherently have specifications that are different from the petrochemical industry due to the need for sterilization, implantation and equipment. Choices for pipe materials may be multiple, particularly with dozens of grades available for each type of pipe. Narrowing all this down can be really stressful, and the pros and cons of these products would be very helpful.

There are many benefits to each material, regardless of the intended application, including strength, weight, and versatility and, of course, cost. The power, flexibility and lack of reactivity to certain chemicals are some of the benefits of using steel pipes instead of other materials. The stainless steel pipe also normally needs less preparation time before any assembly; the carbon steel is normally coated as a protection before shipment and this protective coating must be removed before any assembly or welding takes place.

The stainless pipe is also obtainable as welded tubing, which is usually cheaper and more readily available than seamless tubing, but the application requirements that restrict the use of welded pipes as the seam was deemed to be a weak area of the pipe. With improved manufacturing techniques over the last few years, weld seam is much less of a problem than it used to be. It is always a good idea to check for any pressure-related requirements or other relevant issues before choosing between welded and seamless stainless pipes.

Types of Stainless Steel Pipes

Stainless steel is a steel alloy with chromium content. When steel is mixed with other elements like chromium, molybdenum, nickel, silicon, carbon, and aluminum it makes an alloy which is called stainless steel. Stainless steels are engineered materials with good corrosion resistance, strength and fabrication characteristics. They can readily meet a wide range of design criteria – low maintenance, service life and load-bearing capacity.

The advantage of having such a product in the market is that it can be milled into sheets, coils, bars, wires, plates, tubes, and pipes. Pipes and tubes made from diverse stainless steel grades are popular in the market and are offered depending upon the use and type of user. This post will discuss 6 popular categories of stainless steel pipes/tubing.

1. Standard Stainless Steel Pipes:

2. Stainless Steel Tubing for General Corrosion-Resistance

3. Stainless Steel Pressure Pipe

4. Stainless Steel Sanitary Tubing

5. Stainless Steel Mechanical Tubing

6. Stainless Steel Aircraft Tubing

7. Aircraft Hydraulic-Line Tubing

Feature of Stainless Steel Pipes

First, the thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher the processing cost will be. Secondly, the process of the product determines its limited performance. Seamless steel tube has low precision: uneven wall thickness, low brightness inside and outside the tube, high fixed-length cost, and pitting on the inside and outside, black spots are not easy to remove; third, its detection and shaping must be processed off-line so it is at high pressure , high strength, mechanical structural materials reflect its superiority.

Production process of stainless steel pipes:

The rolling method is divided into hot rolling, hot extrusion and cold drawing (rolling) of stainless steel pipes.

According to the stainless steel metallographic structure, it is divided into semi-ferritic semi-Martensitic stainless steel pipes, martensitic stainless steel pipes, austenitic stainless steel pipes, austenitic-ferritic iron stainless steel pipes.

Stainless Steel Pipes Manufacturing process

Hot rolling, cold drawing, hot expansion

According to different production methods, it can be divided into SS hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe.

1. SS Hot rolled seamless pipes are generally produced on automatic rolling mills. The solid tube blank is inspected and the surface defects are removed, cut into the required length, centered on the end face of the perforated end of the tube blank, then sent to a heating furnace for heating and perforated on the punching machine. At the same time, the perforation is continuously rotated and advanced. Under the action of the roll and the head, a cavity is gradually formed inside the tube blank, which is called a capillary tube. It is sent to the automatic pipe mill for further rolling. Finally, the whole machine is uniform in wall thickness, and the sizing machine is sizing to meet the specification. The production of hot-rolled seamless steel tubes by continuous rolling mills is a more advanced method.

2. if you want to obtain a smaller size and better quality seamless pipe, you must use cold rolling, cold drawing or a combination of the two. Cold rolling is usually carried out on a two-roll mill in which the steel pipe is rolled in an annular hole formed by a variable-section circular hole groove and a stationary tapered head. Cold drawing is usually carried out on a single-chain or double-chain cold drawing machine of 0.5 to 100T.

3. Extrusion the pipe blank to be heated is placed in a closed extrusion cylinder, and the perforated rod moves together with the extrusion rod to extrude the extrusion from the smaller mold hole. This method can produce steel pipes with smaller diameters.
