Aluminium seamless pipes are lightweight yet incredibly strong, crafted from top-notch aluminium alloys through a unique extrusion process that avoids welded joints. This not only boosts their structural integrity but also gives them a smooth internal surface. Companies like Bosega Pipes & Tubes in Cape Town, South Africa, supply these pipes, which are highly regarded for their outstanding resistance to corrosion, excellent thermal conductivity, and ease of machining. Their seamless design enhances their ability to withstand pressure and ensures uniformity, making them perfect for applications that require precision, strength, and a lightweight profile—think aerospace, marine, and various industrial systems.
Typically, these pipes are made from alloys like 6061, 6082, 6063, and 5083, which feature aluminium as the primary metal, along with magnesium, silicon, and manganese to boost their mechanical strength and resistance to corrosion. Depending on the specific alloy and temper, you can expect tensile strengths between 150 to 350 MPa and yield strengths from 100 to 250 MPa, all while maintaining impressive elongation and ductility. They perform reliably even in low temperatures, making them suitable for both structural and cryogenic applications.
