Special welded tubes are manufactured to meet specific industry standards and customer specifications:
Special welded tubes offer a versatile and cost-effective solution for various industrial applications. Their ability to meet specific performance requirements, combined with their strength and corrosion resistance, makes them an essential component in many industries.
Special welded tubes are used in a variety of industries due to their unique properties and performance capabilities:
The welding process is one of the key ways in which we manufacture custom precision tubing. Our high quality tubing starts as a flat strip of metal. The strip is formed into a tube by a series of rollers and the joint, also known as the seam, is then welded.
Welded tubes play a crucial role in various industries, serving as conduits for fluids, gases, or structural components. Among these, special welded tubes stand out as tailored solutions designed to meet the specific needs of critical applications. These tubes are characterized by their unique features, materials, and manufacturing processes, making them indispensable in a range of sectors. Here, we explore what makes special welded tubes special and their applications in different industries.
Carbon Steel pipe is superior in strength, workability, and adaptability.
Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing - are used to ensure a consistent weld. Just like with seamless manufacturing, welded tubes can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of coiled tube, these can also be measured during coiling using a laser measurement.
And it’s available in sizes, pressure classes, and chemical compositions to meet the most diverse project specifications.
Straight seam or spiral, forged fittings or fabricated, steel pipe can be designed and manufactured into virtually unlimited configurations to service the demands of nearly any system.
Whether you’re looking for single cut-to-length pieces or truckload quantities, we’ll have what you need, or we’ll find it for you - we have access to a considerable variety of stock material, imported and domestic.
Regardless, all materials supplied by Imperial Pipe are guaranteed and certified to your specified standards
Welded tubing offers the advantage of high quality, low cost tubing produced in large volumes. Tubing made from metal strip that is cold-rolled and then welded offers a high degree of tolerance control and it's possible to produce such tubing from alloy grades that are less suitable for extrusion, either for quality or cost reasons.
Special welded tubes, often used in critical industrial applications, require careful handling and transportation to ensure they reach their destination in optimal condition. These tubes may vary in size, material, and specifications, making their proper delivery essential.
