Seamless tubes and welded tubes are two widely manufactured products used in various applications like construction, chemical factories, and hydraulic boilers, oil and gas transportation, water supply, and more. The manufacturing methods are different. As the name suggests, welded tubes have welded joints, making them more vulnerable to leakage, breakage, and corrosion from the welded joints. On the other hand, seamless tubes are more durable and do not leak. At the most, they bend when the pressure is extreme. This is why carbon steel tubes with no joints are manufacturers’ favorite.
Materials used
The seamless steel pipes are made of high-quality alloy steel or carbon steel and are manufactured by hot rolling and cold drawn techniques. Seamless steel tubes are available in various shapes and sizes and are used in industries like petrochemicals, automobiles, oil and gas, nuclear stations, hydropower stations, construction, etc. These industries also use welded pipes to perform very similar functions, with the only difference that these pipes are prone to damage and erosion.
High pressure endurance and purity
Another benefit of seamless tubes over welded tubes is that it offers greater corrosion resistance because there is less opportunity for impurities. Using seamless tubes let you steer clear of the possible defect and flexibility that could be said about welded joints in welded tubes. Unlike welded tubes, seamless tubes do not additional testing for weld integrity. Thus, seamless tubing is often more suitable for critical applications.
However, both seamless and welded tubing has specific pressure standards to meet. Choose a trusted manufacturer of seamless tubes so you get the best quality every time.
