Seamless Stainless Steel Pipe - 304 - 316L
Seamless Stainless Steel Pipe - 304 & 316L
Precision Manufactured · Corrosion Resistant · High Reliability
We supply high-quality304and316Lseamless stainless steel pipes, widely used in oil & gas, chemical, medical, food processing, shipbuilding, and architectural applications.
Key Features
● Excellent Corrosion Resistance
Grade 304 for general industrial and domestic use.
Grade 316L contains molybdenum (Mo), offering superior resistance to chlorides, acids, and alkalis - ideal for coastal and high-corrosion environments.
● Seamless Structure
Cold drawn or cold rolled without welding seams, ensuring higher pressure resistance and no weld defects.
● Smooth Inner & Outer Surfaces
Available in pickled, bright annealed, or polished finishes to meet sanitary and aesthetic requirements.
● High Dimensional Accuracy
Tight tolerances on OD and wall thickness for easy installation and secondary processing.
● Wide Temperature Range
Serviceable from -196℃ up to 800℃, suitable even for cryogenic applications.

Case: A seawater cooling system in a coastal chemical plant replaced welded pipes with 316L seamless stainless steel tubes. The seamless structure eliminated pitting corrosion at weld joints, while molybdenum content resisted chloride attack. Result: maintenance intervals extended from 6 months to over 3 years.
