Seamless Stainless Steel Pipe

Seamless Stainless Steel Pipe

Seamless Stainless Steel Pipes are engineered for demanding environments where high-temperature strength, corrosion resistance, and durability are essential. Available in sizes ranging from 1/8″ to 36″+ and in schedules from S/5s to XXS, these pipes are widely used across industries including petrochemical, food processing, pharmaceuticals, energy, and construction. Seamless construction ensures a uniform structure and superior pressure resistance compared to welded alternatives.

Key Features and Standards:

These pipes are manufactured in compliance with international standards such as ASTM A312, ASTM A213, ASTM A269, and ASTM A270. These cover both general service and specialized applications such as heat exchangers, boilers, and sanitary systems. Available services include bending, cutting, grooving, polishing, and threading, making them adaptable for custom requirements. Surface treatments vary from annealed and pickled for industrial use to polished finishes (180, 240, 400 grit) for sanitary and decorative purposes.

Material Grades and Corrosion Resistance:

The available stainless steel grades include austenitic and ferritic alloys like TP304, TP304L, TP316, TP316L, TP310S, TP321, and TP347, among others. Each grade is selected based on mechanical strength, temperature resistance, and corrosion performance. For instance, TP316L offers superior corrosion resistance in chloride environments, while TP321 and TP347 are ideal for high-temperature service with excellent creep strength.

Manufacturing Process:

Seamless stainless steel pipes are produced from solid round billets through piercing or gun drilling methods. The manufacturing process involves billet inspection, heating, mandrel piercing, and precision rolling and stretching. This results in a seamless structure with consistent wall thickness, high dimensional accuracy, and enhanced mechanical properties. Every pipe is meticulously formed to meet strict tolerance and performance standards.

Applications and Versatility:

Due to their seamless integrity, these pipes are ideal for use in chemical processing plants, oil and gas refineries, food and beverage systems, pharmaceutical manufacturing, and power generation. Their ability to handle high pressure, temperature, and corrosive media makes them indispensable in critical systems where failure is not an option. From sanitary environments to extreme industrial settings, these pipes deliver reliable performance and long-term value.
