Stainless Seamless Steel Pipe


Stainless steel is an iron alloy that contains a minimum of 10.5% chromium. Alloying elements such as nickel, molybdenum, titanium, carbon, nitrogen, and copper can boost the strength, formability, and other properties of stainless steel. Different alloys offer different levels of corrosion resistance.

Stainless steel alloys offer greater cryogenic toughness, a higher work hardening rate, increased strength and hardness, greater ductility, and a more attractive appearance compared to carbon steel.

Application of stainless seamless steel pipe:

Chemical plants
Aviation fields
Marine equipment
Cryogenic transportation
Medical & architectural industries
High-Pressure Fuel Lines
Hydraulic Control Applications

Benefits of stainless seamless steel pipe:

Stainless steel pipe is resistant to rust and other corrosive attack. It is heat-resistant for high-performance and high-temperature use.

Manufacturing process of stainless seamless steel pipe:

Typical methods for manufacturing seamless stainless steel tubing are by extruding, gun drilling or piercing. However, the extrusion process provides the most uniform OD (outside diameter) and ultimately the most concentric ID (inside diameter). In addition, extrusion is the only process most suitable for long length seamless stainless steel coil tubing.

Tests of stainless seamless steel pipe:

Stainless seamless steel pipe should be manufactured to applicable standards and fully tested for potential defects before being prepared for shipment to the customer.


After the tube is fully formed to the desired specification it is hydrostatically tested to ensure integrity. Hydrostatic testing determines and verifies the tubing meets the specification. Several types of information can be obtained through this verification process. Key inspection data can be identified through the hydrotest process, such as:

Material flaws
Mechanical properties
Specific hard spots that can fail when hydrogen is present
Stainless steel coil tubing can be level wound on spools for shipment or straightened
and cut to specific lengths designated by the customer.
Products can be polished and stenciled with pertinent information for lot traceability and manufacturing identification.
