What is Seamless Stainless Steel tube

Seamless stainless steel tube is completely homogenous tube, the properties of which give seamless tubing more strength, superior corrosion resistance, and the ability to withstand higher pressure than welded tubes. This makes stainless seamless tubing more suitable for critical applications in harsh environments. When bending and torsion strength are the same, the weight of ss pipe is lighter. AHL Steel is one of the toppest professional seamless stainless steel pipe manufacturer. We provide additional customer services such as tube cutting and polishing.

Features of SS Steel Tube

Superior Corrosion Resistance

Seamless stainless steel tube has superior corrosion resistance and tensile strength because it has little potential impurities. Using stainless seamless tubing allows you to avoid the potential of defects and differences in malleability, seamless stainless steel tubes do not require testing for weld integrity.

Higher Working Pressure Resistance

Due to having no welded seam, stainless seamless tubing has 20% higher ASME (American Society of Mechanical Engineers) working pressures compared to welded tubing of the same material and size.

Stronger

Seamless stainless steel pipe contains a minimum of 10.5% chromium. Alloying elements such as nickel, molybdenum, titanium, carbon, nitrogen, and copper can increase the strength, hardness, formability, and other properties of stainless steel. In addition, stainless steel alloys offer greater cryogenic toughness, higher work hardening rate, increase ductility.

Low Maintenance Cost

Since the stainless steel is resistant to rust and other corrosive attack, the seamless stainless steel tube is easy to clean and maintain which cause lower maintenance cost in the future.

Applications of AHL Stainless Seamless Pipe

Seamless stainless pipe is often preferred by applications which require high anti-pressure ability and corrosion resistance in extreme harsh environments. With excellent performance, AHL seamless stainless tubes have been served in industries such as:
