A seamless steel tube is usually a circle with no visible seams on it and generally has a hollow inner part. These are usually made out of stainless steel, iron, carbon fiber, or other non-metals. Steel manufacturers use different processes when forming them. One of the most common ways is by bending the steel to create the desired cylindrical shape.
In most cases, these tubes are used in automobiles because they can be completely seamless steel tube. However, there are also automotive parts that make use of the seamless tubes. One example would be the exhaust system in cars. This system allows exhaust gases to exit the vehicle at a higher velocity. This type of system may also be combined with solid tail pipes for a complete seamless design.
Another application of this seamless steel tube is in aerospace and defense industry. Since its invention in the mid 1960’s, its mechanical properties have enabled manufacturers to fabricate airframes, components, parts and other items using this material. Its corrosion resistance, thermal conductivity and ability to exhibit elasticity are also some of its notable properties.
A major benefit of the seamless steel tube is that they offer flexibility. They can be made to fit in any position. This property enables designers to create various shapes and dimensions. The tube itself may also be formed into the same shape as the part or item being manufactured.
Another advantage of the tube is its heat resistance. It can withstand extreme temperatures of up to 500 degree Celsius without any visible damage. The heat-resistant property of this pipe helps manufacturers avoid the use of different types of metals in the manufacturing process. They can use only the high alloy steels which do not suffer from heat stress corrosion.
Seam corrosion is one of the most important disadvantages of welding pipes using this material. The heat stress causes the filler metal to be stripped off the pipe after welding. Seam corrosion leads to blisters on the inside of the pipe and in some cases, the metal feed lips get completely detached from the inside of the pipe. Since the tube cannot be reused, manufacturers have to invest in new raw materials. Therefore, the investment they make in new seamless tubes or products is often replaced by the savings they make in the manufacture of products.
For seamless welded products, there are some steps which are generally taken during the manufacturing process. The basic process starts with the induction of electric current into the welded area. Then, a thin welding torch is used to heat up the welded area until it becomes molten. Finally, the item is pulled through the welded area and passed through a die. The seamless pipe comes out as two identical sections when the die cools.
Since there are some inherent challenges associated with welding steel, various techniques are used. Some of these include: ultrasonic welding, MIG welding, TIG welding and SAE (stainless steel) welding. Ultrasonic welding is a very convenient process where two pieces of the seamless pipe are placed close together, the electrical current is applied and the pieces are heated in an ultrasonic bath. The pieces come out as one piece to the bath cool. MIG welding uses the filler metal to create the seam while the TIG uses tungsten gas as the filler metal in the tig welding process.
Seamless steel pipes are mostly used for construction purposes. They are strong, flexible and lightweight. However, they have their own set of specific advantages. These are:
The above-mentioned advantages make seamless steel pipe an important component of the entire construction process. It is also used in the fabrication of tubes for the ships, trains and other heavy machinery. Most of the high-volume manufacturers prefer this kind of welding because it increases the precision, stability and longevity of the products they produce. In addition to that, they are generally used in the construction of the inner diameter and the external diameter joints of the products.
To manufacture seamless steel pipe, high precision cold drawn parts are made. These parts consist of good surface quality and high tolerance. This is so because a small amount of force is needed to get the desired results. The seamless steel pipe is usually manufactured by using high performance stainless steel with a low alloy steel content.
